Which of the following provides an example of epistasis? A) Recessive genotypes for each of two genes (aabb) results in an albino corn snake.
B) The allele b17 produces a dominant phenotype, although b1 through b16 do not.
C) In rabbits and many other mammals, one genotype (cc) prevents any fur color from developing.
D) In Drosophila (fruit flies), white eyes can be due to an X-linked gene or to a combination of other genes.
E) In cacti, there are several genes for the type of spines.

Answers

Answer 1
Answer: D) In Drosophila (fruit flies), white eyes can be due to an X-linked gene or to a combination of other genes. 

Epistasis is the communication and the interaction of the genes. These are not within the alleles but with the genes themselves only. Also known as the genetic background, the genes are dependent on their effect to show the trait. 
Answer 2
Answer:

Answer: c) in rabbits and many other mammals, one genotype (cc) prevents any fur color from developing

Explanation: idk i just got the answer wrong and it said that was correct lol

Which of the following best describes a characteristic of Fungi that differentiates them from Bacteria? (2 points)Fungi are eukaryotes, while Bacteria are prokaryotes.
Bacteria are heterotrophs, while Fungi are autotrophs.
Bacteria have gametangia, while Fungi do not.
Fungi have cell walls, while Bacteria do not.

Answers

The correct answer to the question above is the first option, Fungi are eukaryotes, while Bacteria are prokaryotes. That statement best describes a characteristic of a Fungi and how it differentiates them from Bacteria. 

Answer:

The correct answer would be "Fungi are eukaryotes, while bacteria are prokaryotes.

Fungi are referred to the group of eukaryotic organisms which include microorganisms (such as yeast, molds) as well as a mushroom.

They contain chitin in their cell wall.

They are heterotrophic in nature that is, they obtain their food by absorbing molecules from the outside environment.  

Fungi can reproduce sexually as well as asexually.

Which of the following is a nutritional monomer that can be transported in the blood? A. Sucrose B. Maltose C. Alanine D. Dipeptide

Answers

Answer:

Alanine

Explanation:

The nutritional monomer that can be transported in the blood is C. Alanine.

Sucrose and maltose are disaccharides made up of two sugar molecules and are not transported directly in the blood. Dipeptides are formed by the combination of two amino acids, and they are typically broken down into individual amino acids before being absorbed into the bloodstream. Alanine, on the other hand, is an amino acid and can be transported in the blood as part of the body's protein metabolism.

Answer:

The nutritional monomer that can be transported in the blood is option C: Alanine. Alanine is an amino acid, which is a monomer of proteins. Amino acids can be transported in the blood to be used for various cellular functions and protein synthesis.

Answer:

nervous

Explanation:

The nervous tissue is one of the four basic tissues of the organism, it is formed by two types of cellular elements, it represents the fundamental component of the structures and organs that make up the nervous system. The main function of the nervous tissue is to capture internal and external stimuli and transform them into nerve impulses. All modifications of the external or internal environment and sensory stimuli such as temperature, pressure, light, sounds and taste, among others, are detected, examined and transmitted by nerve cells. On the other hand, the nervous tissue is in charge of coordinating the motor, glandular, and visceral functions of the individual.

Although I would tell you that whenever mRNA is affected, protein synthesis is one of the most important and relevant causes in cell life.

Explanation:

Another fact to add is that according to the protein that is selected, determine the vitality or not of the cell.

In the inoculation of the toxin if the synthesis of a protein that makes up the membrane structure, or of the fundamental structures for vitality, is affected, the cell will go into apoptosis or die.

On the other hand, if the protein synthesis is referred to some enzyme, or a second protective messenger, the cell continues with its vitality.
