Cells that secrete hormones into the bloodstream which are then carried away to target cells are referred to as __________ cells.a. paracrine
b. endocrine
c. autocrine
d. exocrine

Answers

b. endocrine

Paracrine cells are the ones that secrete a sign directly to its neighbors, to the extra cell space and not to the blood.

Endocrine cells are the ones that secrete a hormone to the blood system to be distributed to some specific place in the body.

The autocrine system is the release of a hormone from the cell to that same cell.

The exocrine glands are those who release a specific type of hormone or enzyme to some part of the body, through canals.

Can the genotype for a gray-bodied fly be determined? Why or why not? Describe all of the possible genotypes for a fly with that phenotype

Answers

Answer:

The genotype of a fly can be determined gray bodied is dominant over black body flies. The possible genotype of a fly is either YY or Yy.

Explanation:

The genotype of a gray bodied fly can be determined with the help of punnett square. The gray bodied fly is crossed with black bodied fly, the original genotype of the fly can be determined. This type of cross is known as test cross.

If the cross results in the formation of all gray bodied progeny, the fly is homozygous dominant with the genotype YY. The cross results in  the mixture of progeny with gray and black body , then the genotype of a fly is heterozygous dominant Yy.

Thus, the genotype of a fly can be determined by the test cross. The fly may have genotype either YY or Yy.

Why is it necessary for each gemete to contain only half as many chromosomes as a body cell

Answers

Answer:

This is for the offspring to show traits that come from both the mother and father.

Explanation:

Gametes are formed by a kind of cell division called meiosis in which the chromosome number is halved. Thus the said gamete cell is said to contain a haploid number of chromosomes.

The fusion of two haploid gametes is called fertilization. It results in the formation of single celled zygote which has a diploid number of chromosomes. The zygote now divides and develops to produce the offsprings whose somatic cells are diploid.

Answers

Explanation:

It is produced industrially by fermentation using yeast or bacteria. Marmite's defining ingredient is made from brewer's yeast heated to create glutamic acid, which is used by farmers to increase plant growth and boost crop yields.

Why would cells die if they were unable to make (or otherwise obtain) the amino acid arginine?

Answers

Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.

Explanation:

Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.

Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.

Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning. So the cell dies because it cannot function properly.
