Answer:
The correct answer will be-
1. decrease in blood volume
2. secretion of renin from juxtaglomerular apparatus
3. production of angiotensin II
4. secretion of aldosterone
5. sodium reabsorbed from distal tubules and collecting ducts
Explanation:
The RAAS pathway or Renin-angiotensin II-aldosterone pathway gets activated in the human body to maintain the osmolarity and blood volume.
When the receptors in the blood sense the low volume of water in the body sends signals to the brain which activates the secretion of the renin from the juxtaglomerular cells. Renin helps converts the inactive angiotensin to angiotensin I and II which help reabsorption of sodium ions. This activates the production of aldosterone which increases the reabsorption of the sodium ions into distal and collecting ducts.
Answer:
Explanation:
Given -
Total Population - 
Individuals with homozygous HbA/hbA genotype - 
Individuals with homozygous hbs/hbs genotype -
Individuals with heterozygous hba/hbs genotype - 
Let us assume the given population is in Hardy Weinberg' equilibrium
The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.
The frequency of hba allele is equal to
Surface area is an important factor in limiting cell growth because
a. the cell can burst if the membrane becomes too large.
b. materials cannot enter the cell if the surface is too large.
c. the cell may become too large to take in enough food and to remove enough wastes.
d. waste products cannot leave the cell if the cell is too small.
Answer:
c. the cell may become too large to take in enough food and to remove enough wastes.
Explanation:
The exchange of substances with surroundings is done by cells by the process of diffusion. The rate of diffusion of substances requires the presence of a higher surface area than volume. As the cells become larger, their surface area is reduced with respect to the volume. Therefore, larger cells can not support the diffusion of substances in and out as required for its proper functioning. If cells are allowed to grow continuously, they will not be able to intake the requires materials such as food and to release the waste outside.
