The environment determines how the genotype is expressed. The environment influences gene activity, which leads to a change in the phenotype of fur color.

Coloration of the fur of Himalayan rabbits is regulated by gene C. The rabbit raised at 20°C (left) has pigmentation on its ears, nose, and paws because the gene is active when environmental temperatures are between 15 and 25°C. These areas are where the rabbit's body loses the most heat. Because gene C is dormant at temperatures above 30°C, the rabbit raised in this environment (on the right) lacks fur pigmentation.

Gene expression for fur color in Himalayan rabbits is influenced by temperature. The follicle cells taken from Himalayan rabbits tend to die when kept at warmer temperatures. Himalayan rabbits use fur color to communicate fitness during the breeding season.

The statement that best describes the most important factor that allows cells to keep accomplishing their many tasks is that Cells are constantly producing usable energy in the form of ATP.

ATP is also produced during the cellular respiration process in a cell's mitochondria. This can be accomplished through either aerobic respiration, which demands oxygen or anaerobic respiration, which does not. From glucose and oxygen, aerobic respiration generates ATP (as well as carbon dioxide and water).

Adenosine triphosphate (ATP) is the cellular energy source for use and storage. ATP is a nucleoside triphosphate with the structure of a nitrogenous base (adenine), a ribose sugar, and three sequentially bonded phosphate groups.

Our cells produce ATP in two ways: substrate-level phosphorylation and oxidative phosphorylation. Plants have one more. They use sunlight energy to produce ATP during photosynthesis.

Gene expression is the process of turning genes on or off. Gene expression can occur at any point of the transcription-translation process but most often occurs at the transcription level.

Gene expression is the process of turning genes on or off. Proteins that can be activated by other cells and signals from the environment are called transcription factors. Transcription factors bind to regulatory regions of the gene and increase or decrease the level of transcription. Other mechanisms of gene regulation include regulating the processing of RNA, the stability of mRNA and the rate of translation.

Turning the correct genes on and off is an essential component to maintaining a cell’s functionality. Only some of a cell's genes are translated and expressed (transcribed) by the cell. By activating or deactivating the expression of the proper genes, cells respond to environmental cues. Gene regulation is the process of turning genes on or off.

The two organelles from the cell body that are involved in preparing for the release of neurotransmitters are the endoplasmic reticulum and the Golgi apparatus.

The neuron's cell body contains a nucleolus, nucleus, Golgi apparatus, endoplasmic reticulum, ribosomes, lysosomes, endosomes, mitochondria, and peroxisomes. A vesicle is a tiny sac made of a membrane that contains liquid. This facilitates the movement of materials into or out of the cell.

In neurons, the vesicle helps to transport and store the neurotransmitter. The ribosomes in the rough endoplasmic reticulum are the location where the proteins that make up the vesicles are produced. Vesicle biosynthesis starts once this protein migrates from the smooth ER to the Golgi apparatus. From there, the vesicles will bud off and be transported to the neuron terminal to become neurotransmitter vesicles.

If the organism secretes an excess of ADH, urine would be less diluted and showing a bright yellow color due to salts concentration. Options: less water in it and bright yellow.

Anti Diuretic Hormone is a molecule that helps kidneys to control water loss through urine.

The ADH, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. Through these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism's needs.

When the organism secretes too much ADH, the body retains too much water, and blood volume increases.

In these cases, urine would have less water and would be bright yellow because there would be a higher concentration of salts and other waste elements.

Citrulline have to be supplied to the mutants of Neurospora that identified three classes of mutants that needed arginine added to minimal media that had a defective enzyme in order to grow.

The amino acid arginine is synthesized by first converting a precursor to ornithine, that is then transformed to citrulline, which is then converted to arginine. Every one of these three steps is controlled by a different enzyme, which is encoded by a different gene.

The synthetic pathway is undamaged in wild type Neurospora, and spores can thrive on minimal medium even without addition of amino acids. Some enzymes in the pathway are non-functional in mutant Neurospora, preventing spores from growing on minimal medium. All of the mutants in this section are referred to as arg- mutants because they all grow when the minimal medium is supplemented with arginine.

Performing a Punnett square would be too extensive. So we can think about an easier way.

We know that the three genes assort independently from each other. So we can analyze each trait separately, to get

F1) 1/4 YY, 1/2 Yy, 1/4 yy

F1) 1/4 ZZ, 1/2 Zz, 1/4 zz

So, to get all the possible genotypic proportions of the progeny, for each combination, we must multiply their respective genotypic proportions. For instance,

Genotype                Proportion

XXYYZZ                  1/4 x 1/4 x 1/4 = 1/64

XXYyZZ                   1/4 x 1/2 x 1/4 = 1/32

XXYYZz                   1/4 x 1/4 x 1/2 = 1/32

XXYyZz                    1/4 x 1/2 x 1/2 = 1/16

And so on until you complete all the possible combinations.

We are asked about the fraction of offspring that are predicted to have the genotype xxyyzz. So, following what we  did before, we just need to multiply the proportions only for homozygous recessive genotypes. This is
