O Traits are inherited when genes are passed from parents to offspring.
Answer:
C and e ( The 3rd and the 5th one)
Explanation:
Offspring get everything from parents. One could look like either the parental sex: xx or the parent sex: xy
Or the offspring could look like a mixture of each parental or the parental's parents.

2. Cyanobacteria were the first photosynthesizing organisms and Cyanobacteria lived in the ocean.
3. Oxygen increase weathering leads to formation of soil.
Factors made the land a place where the first land plants could thrive are abundant sunlight for photosynthesis and new, nutrient-rich soil made of cyanobacteria as well as deteriorating of rock.
Cyanobacteria were the first photosynthesizing organisms that lived on Earth 3 billion years ago. Cyanobacteria live anywhere on the earth where light and moisture is available i.e. in the open oceans, lakes and streams, in soils, hot and cold deserts, hot springs and salty water.
Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increase which help in the formation of soil. Oxygen directly take part in the chemical weathering of rocks through the process of oxidation. In this process, oxygen reacts with a substance present in the rock and forms oxides which will result in weathering.

2. The food comes from the air through the plants leaves
3. The plant makes its food from the carbon dioxide and water
4. The plant makes its food from minerals and water
Answer:
Actually, you made me confused!
The food comes from plant root in the form mineral's and water and they also use Gas as CO2.
If there is sunlight, they can even convert the light energy into Chemical, in the form of sugar (Glugose)
We call this process as Photosynthesis.
Answer is 3, food dont come from ground, nor just CO2, it requirs minerals and Water too...

1. Is combined with oxygen to make sugar molecules
2. Is absorbed through the roots of plants
3. Comes from the air
4. Is actually a source of food
Answer:

Choose which assumption must be made in order for this estimate of broad-sense heritability to be correct.
a. The phenotypic variance of the genetically identical plants is the same as the genetically variable population.
b. The genetic variance component is strictly the result of additive genetic variance.
c. The environmental variance of the genetically identical plants is the same as that of the genetically variable population.
d. There is no phenotypic variance associated with the environment.
The assumption 'environmental variance of the genetically identical plants is the same as that of the genetically variable population' is CORRECT. It is used to estimate the variation due to genetic factors.
Heritability (h2) refers to the proportion of the variability of a given phenotypic trait due to genetic factors.
Broad-sense heritability is affected by genetic and environmental factors.
Broad-sense heritability can be estimated as H² = VG/VP, where VG and VP represent genetic variability and phenotypic variability, respectively.

How waste is removed from plant body ?
Answer:
Living organisms sustain life, based on certain life processes. These life processes help to regulate their daily activities. Excretion is one among them. The metabolism takes place in the cells of living organisms resulting in both useful and toxic products. The accumulation of toxins may harm the organism. Thus, the living organisms remove all these metabolic wastes from their body and this process is called excretion. Different organisms follow different modes of excretion. Let’s have a glance at excretion in plants and how excretion in plants is different from that of animals.

Which side is hypertonic ? A or B ?
Which side will gain water
What is c ?
Answer:
1-b
2-b
3-phospholipid bilayer
B side is hypertonic. It will gain water. C is Phospholipid layer.
What is Hypotonic Solution?
A hypotonic solution is a type of solution that has a lower osmotic pressure than any other solution to which it is compared. It is a solution in which a small amount of solute passes across a semipermeable membrane compared to the amount of solute in the other solution.
If the solute concentration outside the cell is lower than inside the cell, these solutes cannot cross the membrane, so the solution is hypotonic to the cell.
The cell membrane consists of a phospholipid bilayer containing embedded proteins present between these two solutions where a hypotonic solution has a relatively low concentration of solutes.
Thus, B side is hypertonic. It will gain water. C is Phospholipid layer.

what type of weather is typically associated with the air pressure system near Salem
Answer:
According to common weather maps of the region surrounding Salem, Massachusets, the weather typically associated with the air pressure system is rain.
Explanation:
Given the nature of warm air and its tendency to rise, warmer regions tend to fall under the low-pressure system category. These systems, due to the movement of the warm air, have lower pressure at their center than in the areas surrounding them. As the wind blows towards the low-pressure air systems, the cooler and warmer air meet within the atmosphere, which causes the water vapor to condense and form clouds. Oftentimes, these clouds then precipitate, causing rain.

what is a protein that recognizes and responds to a signal
The answer to your question is receptors.
What are the 4 steps of protein synthesis?
Answer:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled.
The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.
Since the DNA cannot leave the nucleus , copies of the section needed to make the protein are made, this is called transcription.
This done by first opening the double helix with an enzyme called DNA Helicase. Another enzyme called RNA polymerase will match new bases to the original DNA attaching them in a long strand of mRNA. When the enzyme reaches the end the strand will be removed and the DNA can close.
Which phrase best defines the orbit of Earth? A. the position in pace of Earth at a certain time B. the distance from the sun to Earth at any point C. the spin of Earth on its axis as it moves forward D. the path Earth travels as it revolves around the sun
The phrase that best defines the orbit of Earth is the path Earth travels as it revolves around the sun. That is option D.
Rotation of the EarthThe earth is one of the nine planets that makes up the solar system.
An orbit is a regular, repeating path that an object takes around another one.
The earth and other planets travels round the sun. That is to say, the orbit of earth is defined as the path the earth passes through or travels as it revolves around the sun.
The earth rotates about its own axis within 24 hours causing day and night while it travels round the sun in every 365.25 days.
