ANSWER is A
When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.
Explanation:
giving the cell a rigid, inflexible shape.
B
allowing water to pass into the cell.
с
protecting the cell from the outer environment.
D
regulating movement of materials in and out of the cell.
Cell membranes have each of the following functions except for giving the cell a rigid, inflexible shape. Thus, the correct option for this question is A.
A cell membrane may be defined as a type of biological membrane which separates the inner surroundings of the cell with respect to the outer environment. It is semi-permeable in nature. It performs numerous functions for increasing the survival of an organism.
Cell membranes generally protect the inner content of the cell along with various organelles from the outer environment. It also regulates the movement of materials in and out of the cell either by simple diffusion or by transporters. It allows the easy passage of water into the cell.
Therefore, cell membranes have each of the following functions except for giving the cell a rigid, inflexible shape. Thus, the correct option for this question is A.

Pepsin is found in the stomach. Salivary amylase is found in the mouth. Arginase is also found in the liver. The pH of the pepsin in the stomach is acidic. The pH of the pepsin in the stomach is acidic (around 2), the mouth pH is nearly neutral, and the liver pH is basic.
Different organs of the body function well at different pH levels because enzymes exhibit their best activity in a specific pH range The enzyme that acts in the stomach can't act in the mouth due to a change in pH. The mouth has a nearly neutral pH, ranging from 6.5 to 7, and in this place, the salivary amylase works best and carries out the initial digestion of the carbohydrates. Pepsin works in stomach having a pH nearly 2.
Hence, the pepsin enzyme in the stomach works best at an acidic pH of about 2. The amylase works best at neutral pH. The liver enzyme arginase works best at a basic pH.

Answer:
the answer is B ( the stomach is more acidic thank the mouth, which is more acidic than the liver
Explanation:
B. the integration of the bacteria's genome with the viral genome outside of the bacteria's cell wall.
C. the integration of the viral genome into the ribosomes present in the bacteria to direct protein synthesis for the capsid formation.
D. the integration and stabilizing of a virus into its capsid, which provides protection until conditions are better for reproduction.
Answer:
The correct answer is A. the integration and stabilizing of the lambda 1 phase into a host cell's genome.
Explanation:
Viruses have two reproductive cycle i.e, lytic and lysogenic cycle. During the lysogenic cycle, the viral genetic material gets incorporated into the bacterial DNA and gets replicated with the bacterial genome using bacterial molecular machinery.
During the lytic cycle, the viral protein is expressed which forms the progeny phages which release from the cell through cell lysis. Then the new phages infect other cells. Therefore during the lysogenic cycle, integration and stabilization of the viral genome in the host cell's genome occurs. Therefore the right answer is A.
O A. The proteins of the viral capsids kill all the cells around an
infected cell
B. The virus particles produce toxins that poison cells throughout the
body
C. The new viruses formed inside one cell infect and quickly kill other
cells.
D. The viral nucleic acid attaches to the DNA in a host cell and then
lies dormant

Answer:
A genetic disorder is a disease that is caused by the change in the sequence of DNA. Down Syndrom and Huntington disease are two examples of genetic disorders.
Explanation:
A genetic disorder is a change in the sequence of the DNA that results in a disease or condition. These disorders are caused by the mutation of one or multiple genes, by damage in chromosomes, or by environmental factors.
Down syndrome is a known genetic disorder where there is an extra copy of chromosome 21 instead of the two copies. People with Down Syndrom have intellectual difficulties and a different physical complexion that can lead to some problems.
Huntington disease is a genetic disorder that causes the degeneration of neurons, which brings emotional, cognitive, and movement problems that worsen with time since it is a progressive disease.
