Be safe!
"Enzymes are organic catalysts" refers to the fact that enzymes are an organic class of biological molecule that act as catalysts in chemical reactions.
Catalysts are compounds that speed up chemical reactions without being consumed or changed in any way. In living organisms, enzymes are essential for many biochemical processes, including the breakdown of food during digestion, the synthesis of molecules, and the facilitation of cellular processes. Enzymes help maintain vital biochemical processes, maintaining the fundamental activities of life, by reducing the activation energy required for a reaction.

Heat Transfer discussion based question
Your response needs to be AT LEAST 2 paragraphs.
DISCUSSION QUESTION: How is thermal energy transferred?
Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.
Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.

Consider a hypothetical scenario in which the genes that determine body color, eye color, and wing type in fruit flies occur on the same chromosome. To determine the order of the three genes on the chromosome, a researcher looks at hundreds of flies and makes these observations: 90% of flies with red eyes have curly wings. 75% of flies with red eyes have black bodies, whereas the remaining 25% have brown bodies. 1% of flies have curly wings, white eyes, and black bodies. Based on these observations, what is the most probable location of each gene on the given chromosome
Answer:
The most probable location on the chromosome of each gene is:
wing shape gene ------- eye color gene -------- body color gene
Explanation:
To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.
By comparing the parental and the double recombinant we will realize which is the allele that changes in position. The position of this gene is in the middle of the other two genes because in a double recombinant only the central gene changes position in the chromatid.
So, according to this knowledge and the available information in the problem we can estimate the position of the genes in the chromosome.
Phenotypic proportions:
90% of flies with red eyes have curly wings (Parental)75% of flies with red eyes have black bodies (Simple recombinant)25% of flies with red eyes have brown bodies (Simple recombinant)1% of flies have curly wings, white eyes, and black bodies (Double recombinant)90% of individuals are red-eyed and curly-winged. This is a high frequency, which means that this is the parental phenotype. The other parental phenotype must be white eyes and straight wings.
Flies with curly wings, white eyes, and black bodies represent the lower proportion (1%) so this phenotype must be the double recombinant.
Flies with red eyes and black bodies, and flyes with red eyes and brown bodies are intermediate in proportion, so they must be simple recombinant phenotypes.
Parental)
Red, Curly
White, Straight
Double recombinant)
White, Curly, Black
Red, Straight, Brown
Simple recombinant)
Red, Black
Red, Brown
In the chromatid, there are two regions, Region 1 (from the first gene to the gene in the middle), and region 2 (from the gene in the middle to the gene of the other extreme).
The fact that both simple recombinants are red, tells us that the eye color gene and the body color gene are together, and the recombination occurred either in region 1 or 2.
We know that the double recombinant is White, Curly, Black. We also know that the eye color gene and the body color gene are together, so one of these two must be in the middle.
Parentals are red and curly, which means that the eye color gene and wing shape gene are also together. This leads us to assume that the eye color gene is in the middle.
Finally, the fact that the double recombinant is White, Curly, Black, and knowing that the eye color is in the middle and that both the extreme alleles change position, we can assume that the parental Red, Curly is also black, while the other parental is white, straight and brown. So:
Parental)Curly ------ Red ------Black (90%)
Straight ----- White ----- Brown
Simple recombinant)Curly -----White-----Brown
Straight-----Red -----Black (75%)
Curly----Red-----Brown (25%)
Straight ----White-----Black
Double recombinant)Curly-----White------Black (1%)
Straight----Red------Brown

What term is used to describe the state in which molecules are evenly distributed in the available space?
Answer:
equilibrium
Explanation:
The term that is used to describe the state in which molecules are evenly distributed in the available space is dynamic equilibrium.
The molecules of a substance refers to a group of two or more atoms of the substance held together b chemical bonds.
Molecules of solids are fixed about a particular point except they are dissolved in solution. Molecules of liquids and gases, however, move about randomly.
When the molecules of a particular substance are more to one side between two adjacent points in a space, a gradient is created. However, when the molecules of the substance are uniformly distributed in a space, they are said to be in dynamic equilibrium.

please help. i’m literally going to fail biology
Answer: Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Georgia has hypochondriasis, and Leo has a pain disorder. Which of the following do Georgia and Leo most likely
have in common?
O a history of normal medical exams
O significant pain in a specific area
O a preoccupation with the idea of being sick
O an onset of the disorder before the age of 30
Answer:
C. a preoccupation with the idea of being sick
Explanation:
Hypochondriasis and pain disorder are two conditions that deviates from the normal human health. Hypochondriasis, also known as health anxiety, is a condition whereby an individual is fearfully worried about having a serious illness. On the other hand, pain disorder is a condition in which pain results in certain areas of an individual's body due to psychological disposition of such individual i.e. his/her mindset.
Based on the description of both conditions above, it can be observed that both hypochondriasis and pain disorder are as a result of a preoccupied mindset of being sick. One is worried PSYCHOLOGICALLY about being terribly ill (Hypochondriasis) while the other PSYCHOLOGICALLY induces pain on him/herself.
