Explanation:

Genes:
A. in plants exist only in some individuals
B. they determine the structural and functional characteristics of each individual
C. they determine only the functional characteristics of each individual
D. they determine only the characteristics structural of each individual
E. do not exist in prokaryotes

Answers

Answer:

B. They determine the structural and functional characteristics of each individual

Explanation:

Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.

Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics.

Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.

So, the correct answer is B.

Answers

Answer:

d. visceral.

Explanation:

The visceral reflex is one that happens autonomously in the body, aiming to maintain the balance of the body through quick responses to some specific impulses. An example of a visceral reflex is the reduction in body temperature with the release of sweat from the sweat glands.

The visceral reflexes are controlled by the autonomic nervous system, using the sympathetic and parasympathetic nervous system.

The protein salmon has an isoelectric point of 12.1. Suppose you did a pH titration of a solution containing salmon. At what pH will the protein aggregate

Answers

Answer:

The correct answer is - 12.1.

Explanation:

In the case of the same isoelectric point of protein and the pH value of the solution, it is the only condition when aggregation of proteins takes place.

When there is intrinsically disordered proteins or misfolded proteins aggregates known as the protein aggregate. So for the first aggregation takes place at pH= 12.1.

The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?

Answers

Answer:

The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).

Explanation:

Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.

In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.

In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..

Describe the normal process of osteogenesis for compact and spongy bone using the three different types of bone cells and their functions

Answers

Answer:

Osteoblasts penetrate the disintegrating cartilage and replace it with spongy bone. This forms a primary ossification center. Ossification continues from this center toward the ends of the bones. After spongy bone is formed in the diaphysis, osteoclasts break down the newly formed bone to open up the medullary cavity.

Dark skin ( a result of increased melanin production in equatorial populations), is likely a response to ultraviolet radiation because UV radiation causes:

Answers

Answer: Skin cancer

Explanation:

Melanin is a pigment derived from an amino called acid tyrosine. The most common form of melanin is called eumelanin, which is a polymer of dihydroxyindole carboxylic acids and their reduced forms. When a person is exposed to the ultraviolet light (UV) from the sun, the melanocytes will produce eumelanin to prevent the skin from burning and damage to the cell nuclei (where DNA is found) of the epidermis. This melanin production causes the skin to darken. The eumelanin in the skin then acts as a natural sunscreen by blocking the damaging effects of sunlight. So, skin darkens when exposed UV light, thus providing greater protection when needed by producing more eumelanin, but it also becomes more likely to develop melanoma, which is a type of skin cancer. This is because UV rays damage the DNA of skin cells. The DNA (deoxyribonucleic acid) is the genetic material that has the instructios to the growth and functioning of an organisms). Skin cancers begin when eumelanin protection is not sufficient and this damage affects the DNA of the genes that control the growth of skin cells. This results in a tumor, which is the uncontrolled growth of cells (in this case, skin cells) because there will be a mutation in DNA that affects the function of the cells.

What is rcbL, and why is it a particularly useful molecule for studying evolutionary relationships in plants and green algae

Answers

Answer:

RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.

Answers

Answer:

The prime agonist of inspiration is the diaphragm muscle.

The conditions when expiration becomes an active process is : Emphysema, Pneumonia, Bronchitis.

-Expiration is the passive process as there is elastic recoil of lungs following inspiration without contraction of any muscles.

-The elastic fibers in alveoli are damages or filled with mucus and fluid in the disease such as conditions such as emphysema or pneumonia.

-Elastic recoil of lungs.

-Hence, muscle contraction is required to forcefully exhale the air from lungs. Internal intercostal muscles contract to pull the ribs downward and remove air from the lungs.

There are six major groups of enzymes. The categories are based on the types of reactions that they catalyze. What type of enzyme can join together two molecules to make a larger molecule such as a long strand of DNA

Answers

Answer:

DNA ligase.

Explanation:

DNA ligase is a type of enzyme that is responsible for join together of two molecules to make a larger molecule such as a long strand of DNA. This enzyme joins the end of two DNA molecules making it a long strand of DNA. In DNA cloning process, restriction enzymes and DNA ligase enzymes are used to incorporate genes and other pieces of DNA into plasmids so we can say that DNA ligase is responsible for long strand of DNA.
