How is your weight different on Earth and on the moon
Answer:
Your weight on the Moon is 16.5% what you would experience on Earth
Explanation:
Answer:
To find the weight on the moon, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. ... So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:
Also:The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. ... But if you measure your weight on the Earth and on the moon, your weight will be far less on the moon because of a weaker gravitational force,

Explain why Chargaff’s data was an important clue for putting together the structure of DNA.
Answer:
Chargaff's data was an important clue for putting together the structure of DNA because it provided the basis for determining the ratios of the four nitrogenous bases in DNA. Specifically, Chargaff's data showed that the amount of adenine (A) was equal to the amount of thymine (T), and the amount of guanine (G) was equal to the amount of cytosine (C). This helped scientists to understand that the two strands of a DNA molecule pair together in a specific way, with A always pairing with T and G always pairing with C. This information was essential in determining the double-helix structure of DNA.

Question 3: Discuss the four macromolecules that occur in nature, including the building block units of each different macromolecule. ( Only answer if you know the answers to all 3 questions) Will Mark Brainliest.
Answer: 1. Plastics are polymers. A polymer is a substance made of many repeating units. The word polymer comes from two Greek words: poly, meaning many, and meros, meaning parts or units. A polymer can be thought of as a chain in which each link is the “mer,” or monomer (single unit). 2. Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. ... They can even join "head-to-tail" to make rings of carbon atoms. An example of two molecules that contain carbon is compound methane ( 1 carbon bounded to four hydrogen. ) ... Carbon is able to form so many molecules/compounds because each carbon atom can form four chemical bonds to other atoms and, because of its size, it fits in nicely as part of large molecules. 3.

What is the function of the placenta?
A. To protect the developing fetus
B. To help the developing fetus communicate with the mother
C. To hold the developing fetus in place
D. To provide the developing fetus with food, water, and oxygen
Answer:
it's either a or d I know this I'm in child development but I'm pretty sure it's a d but it might help protect the fetus because it's trying to keep it attached and keep it from floating around but it could be d because to provide developing food water and oxygen that would be the only way it could breathe and that's how it gets his nutrients because when the mother is breathing in oxygen and eating that's how the baby gets to take in all that stuff with the mother
To provide the developing fetus with food, water, and oxygen is the function of placenta. Therefore, option (D) is correct.
What do you mean by placenta?An organ that grows inside the uterus during pregnancy is the placenta. A developing infant receives oxygen and nutrients from this structure.
As your womb gets smaller, your placenta will fall out and the blood vessels that were holding onto it will close. This assists with forestalling a lot dying - despite the fact that draining a little is ordinary.
The placenta is the membrane that the mother and fetus use to exchange gases, nutrients, and other things. Syncytiotrophoblast, cytotrophoblast, embryonic connective tissue, and the endothelium of fetal blood vessels all contribute to the formation of the membrane.

The image shown is of a cell cycle. Cycle phases are prophase, metaphase, anaphase, and telophase.
What is a cell cycle?
A cell cycle is the sequence of events that take place in a cell leading to its division and duplication (replication). It consists of two main parts: interphase and the mitotic phase. During interphase, the cell grows and DNA is replicated in preparation for cell division. During the mitotic phase, the cell divides into two daughter cells.
A cell spends the majority of its time in interphase, which is when it develops, duplicates its chromosomes, and prepares to divide.
The cell then exits interphase, enters mitosis, and divides to completion. Each of the resulting cells, known as daughter cells, enters its own interphase to begin a new cell cycle.
The cell cycle is the process by which cells multiply and divide into two new cells. The cell cycle phases are G1, S, G2, and M. At the G1 stage, cells are getting ready to divide.
Therefore, The given image is of cell cycle. The phases of cycle are prophase, metaphase, anaphase and telophase.

Fluffernutter labradors are identical to Earth labradors in every way, except that they grow marshmallows instead of fur. The three possible types of marshmallow skin are: a. Black (tastes like licorice); b. Chocolate (tastes like chocolate); c. Yellow (tastes like vanilla). There are two genes that control for this phenotype, acting in a recessive epistatic manner. The two-locus genotypes that correspond to the phenotypes are:
Answer:
Alleles at the two genes/loci:
- Locus 01: A (dominant), a (recessive)
- Locus 02: B (dominant), b (recessive)
A_B_ (Licorice)
aaB_ (Chocolate)
__bb (Vanilla)
Explanation:
Recessive epistasis is the genetic interaction phenomenon where recessive alleles at one locus mask the phenotypic expression of another gene locus. In a recessive epistatic interaction between two genes, the phenotypic ratio of the three resulting phenotypes is 9: 3: 4. In this case, there are two genes responsible for the three phenotypes Licorice, Chocolate, and Vanilla. One locus is responsible for determining if Fluffernutter labradors will be Licorice or Chocolate. Licorice is dominant and will be expressed if the Fluffernutter labrador has a AA or Aa, while Chocolate is recessive and therefore it is expressed only in aa Fluffernutter labradors. However, the expression of the phenotype is determined by another gene pairing. The epistatic allele b in homo-zygous condition will produce Fluffernutter labradors with Vanilla phenotype.

The cell cycle can be explained as a sequence of events by which a cell duplicates its genome, synthesizes other cell constituents, and eventually divides into two daughter cells.
explanation
The two primary phases of the cell cycle are
1. The interphase It is the phase between two successive M phases. It follows cytokinesis. It is divided into G1, S, and G2 phases.The DNA replication occurs in the S phase of the interphase2. The M phaseThe M phase has four stages
ProphaseMetaphaseAnaphaseTelophaseCytokinesis follows the M phase.
The prophase is the first stage of the M phase. Here, the initiation of condensation of chromosome material takes place. As a result of this, the mitotic spindle is developed. The metaphase is characterized by the complete disintegration of the nuclear envelope. And, the chromosomes move to the spindle equator. In anaphase, two daughter chromatids are formed from the chromosomes. Telophase is characterized by the decondensation of the chromosome material and the formation of two new nuclei (Karyokinesis) and as a result, the mitotic spindle disappearsThe cytokinesis is the last step. Here, the cell gets divided into two daughter cells. In animal cells, it can be achieved by the appearance of a deep furrow in the plasma membrane. However, plant cells require a cell plate as they are enclosed by a cell wall.ConclusionSo, the final answers are,
Interphase - Replication of DNA and follows the cytokinesis.Prophase - Formation of the mitotic spindleTelophase - Mitotic spindle disappears as two new sets of chromosomes arrive at the opposite poles.Cytokinesis - The cell is split into two daughter cells and plants require the formation of a cell plate.Does Plantae have a peptidoglycan
Plants Produce Immunogenic Peptidoglycans, almost all bacterial cell walls, with the exception of those of Archaea, include it as a hard component and it helps give bacteria their characteristic form.
What is Peptidoglycans?In most bacterial species, the cytoplasmic membrane is encased in a hard material called peptididoglycan. It helps maintain cell shape throughout the life cycle and shields bacterial cells from environmental stress. The production of peptididoglycans has a significant role in controlling bacterial cell division. A polymeric macromolecule known as peptididoglycan is composed of linear glycan strands joined together by peptide bridges. The sacculus, which surrounds the cell and is made of covalently closed peptididoglycan, is formed when peptididoglycan is polymerized at the exterior of the cytoplasmic membrane.

If the Earth did not spin what would happen?
Select one:
a. The Earth's wind would bend due to gravity.
Ob. The Earth would only have two large convection currents.
Oc. The Earth would have the same temperature throughout.
Od. The Earth would have several difference convection currents at different latitudes.
Answer:
B. The Earth would only have two large convection currents. The power of Earth's spin to turn flowing air is known as the Coriolis Effect. If the Earth didn't spin, there would be just one large convection cell between the equator and the North Pole and one large convection cell between the equator and the South Pole.
Explanation:
At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
If the planet stopped suddenly, everything on the surface would be destroyed, as the atmosphere, oceans and anything not nailed down kept spinning. Even braking to a halt over a minute would mean everything experienced a sideways deceleration of three-quarters of Earth’s gravity, so ‘down’ would feel like it was at an angle of 38° from the vertical. That’s enough to knock over most buildings.
If it slowed down over several years, it would still be a disaster. Without centrifugal force, the oceans would move towards the poles, dropping ocean depth by 8 km around the equator. Since this is less than the depth of the ocean there, Earth’s water would be divided into two huge polar oceans separated by a belt of land in the middle. Everything north of Spain would be underwater, as well as all of Antarctica.
Once Earth doesn’t spin on its own axis, a day lasts as long as a year. Everywhere receives six months of daylight, gradually heating up the planet to well over 100 °C. The huge central continent would get the hottest, and any remaining lakes and rivers would boil away and be blown to the poles by fierce winds. Even primitive life would only be possible along a narrow strip at the coast.

b. translocation
c. post-translationally
d. dTDP
e. post- transcriptionally
f. hydroxylation
g. DNA synthase
h. phosphorylation
i. methylation
j. GMP
e. CMP
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating deoxythymidine monophosphate (dTMP), which then undergoes phosphorylation to deoxythymidine diphosphate (dTDP), then to Deoxythymidine triphosphate (dTTP), and incorporated into DNA by the DNA polymerase (DNA pol). Thymine in tRNA arises post-transcriptionally, by S-adenosylmethionine-dependent methylation of a uridine 5'-monophosphate (UMP) residue in RNA.
Explanation:
Thymidylate synthase is an enzyme involved in de novo DNA synthesis. This enzyme (thymidylate synthase) catalyzes the transfer of the one-carbon group from 5,10-methylene-tetrahydrofolate (5,10-CH2-THF) to deoxyuridine monophosphate (dUMP) and subsequent methylation to produce deoxythymidine monophosphate (dTMP), which is then phosphorylated to deoxythymidine triphosphate (dTTP) by kinases and incorporated into DNA. On the other hand, specific tRNA methylases catalyze the methylation of transference RNA (tRNA) by using S-adenosylmethionine as a methyl donor. Since tRNA methylation is a post-transcriptional modification, this chemical reaction is considered an epitranscriptomic modification on the RNA molecule.

OA large seaweed alters the direction of water as it flows in the ocean.
A plant's roots absorb water from the nearby soil. This is the best example of how living things play a role in the water cycle. Thus, the correct option is A.
What is Water cycle?The water cycle is the biogeochemical cycle which shows the continuous movement of water within the Earth and its surrounding atmosphere. Water cycle is a complex system that includes many different processes such as evaporation, precipitation. Liquid water evaporates into the form of water vapor, condenses back to form clouds, and precipitates back to the earth in the form of rain and snow particles.
Plants absorb water from the soil. The water then moves from the roots through the stems to the leaves of the plant. Once, this water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the atmosphere. This process of evaporation through the plant leaves surface is called transpiration.
Therefore, the correct option is A.

On a geology field trip, Toccara’s class studies a sedimentary rock formation. Is it possible that material from this sedimentary rock could ever form igneous rock?
Answer:
It is possible for material from a sedimentary rock to become an igneous rock through a process called metamorphism.
Explanation:
It is possible for material from a sedimentary rock to become an igneous rock through a process called metamorphism. Metamorphism is the process of change in the structure, texture, or composition of a rock as a result of being subjected to high pressure, temperature, or both. During metamorphism, the original sedimentary rock is subjected to heat and pressure that is sufficient to cause the minerals in the rock to recrystallize into a new rock with a different composition and structure. If the conditions of metamorphism are high enough, the metamorphosed rock may become an igneous rock. This process can take place deep underground, where the rock is subjected to high temperatures and pressures due to the weight of the overlying rock and the heat of the Earth's interior.
In order to determine the rate of photosynthesis (the conversion by plants of carbon dioxide and water into glucose and oxygen), the oxygen gas emitted by an aquatic plant is collected over water at a temperature of 293 K and a total pressure of 754.0 mmHg. Over a specific time-period, a total of 1.62 L of gas is collected. The partial pressure of water at 293 K is 17.55 mmHg. What mass of oxygen gas (in grams) forms
Answer:
2.87 g
Explanation:
Step 1: Given data
Temperature (T): 293 KTotal pressure (P): 754.0 mmHgPartial pressure of water (pW): 17.55 mmHgVolume of gas (V): 1.62 LStep 2: Calculate the partial pressure of CO₂
The total pressure is the sum of the partial pressures of CO₂and water.
P = pCO₂ + pW
pCO₂ = P - pW = 754.0 mmHg - 17.55 mmHg = 736.5 mmHg
We will convert this pressure to atm using the conversion factor 1 atm = 760 mmHg.
736.5 mmHg × 1 atm/760 mmHg = 0.9691 atm
Step 3: Calculate the moles (n) of CO₂
We will use the ideal gas equation.
P × V = n × R × T
n = P × V/R × T
n = 0.9691 atm × 1.62 L/(0.0821 atm.L/mol.K) × 293 K = 0.0653 mol
Step 4: Calculate the mass corresponding to 0.0653 moles of CO₂
The molar mass of CO₂ is 44.01 g/mol.
0.0653 mol × 44.01 g/mol = 2.87 g
The pressure exert on the one gas in the mixture by the other gases is called partial pressure.
The answer to the question is 2.87g.
The data is given in the question and the data is as follows:-
Temperature (T): 293 K Total pressure (P): 754.0 mmHg Partial pressure of water (pW): 17.55 mmHg Volume of gas (V): 1.62 L
In the question we have to find the total pressure is the sum of the partial pressures of CO₂ and water. The equation we gonna use is:-
[tex]P = pCO_2 + pW[/tex]
To find the pCO2,
[tex]pCO_2= P - pW \\= 754.0 mmHg - 17.55 mmHg \\= 736.5 mmHg[/tex]
Pressure must be in ATM therefore, 1 atm = 760 mmHg.
=[tex]\frac{736.5 mmHg * 1 atm}{760 mmHg} = 0.9691 atm[/tex]
The ideal gas equation is as follows:-
[tex]PV = nRT\\n =\frac{PV}{RT}\\n = \frac{ 0.9691 atm * 1.62 L}{(0.0821 atm.L/mol.K) × 293 K}\\ = 0.0653 mol[/tex]
The mass of the following is:-
The molar mass of CO₂ is 44.01 g/mol.
Therefore,
[tex]0.0653 mol * 44.01 g/mol \\= 2.87 g[/tex]
Hence, the correct answer is 2.87g.
