After the pairs of chromosomes are aligned, anaphase I begins. During this stage, the microtubules, or spindle fibers, pull the homologous chromosomes apart and move them to opposite ends of the cell.
Its called Anaphase when Chromosomes pull apart
Answer:
Answer is hemolytic anemia.
Explanation:
Hemolysis is the destruction of red-blood cells, while anemia when the amount of the red blood cells in the body is lower than the expected or normal.
Therefore, hemolytic anemia can be defined as a disorder or situation where the rate at which the red blood cells are destroyed is faster compared to the rate at which they are made or produced.
This can be caused by bone marrow failure or infections, and inherited blood disorder like sickle cell disease.
The hemolytic anemia is a serious disorder that can damage the heart and other organ of the body, this is because of oxygen starvation, since the red blood cells responsible for carrying oxygen around the body have been affected.
Eating some food items like beans, green vegetables, red meat and legumes can increase red blood cell count.
To solve this problem on genetic dominance, we will need a punnet square.
Let's let P represent purple-flowered and p represent white-flowered.
We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.
<u>P</u> <u>P</u>
p| Pp Pp
p | Pp Pp
As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.
Since each flower has a dominant and recessive allele, they are heterozygous.
Therefore, the solution to this problem is D.
Answer: Mutualism
Explanation: The definition of mutualism states " interaction between two or more species where each species has a benefit". The bird is getting food from the insects and the horse is getting the insects removed. Both are benefited.
Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.
<h3>How is GFR regulated?</h3>
- The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
- GFR is the sum total of filtration rates of all the working nephrons in the kidney.
- Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
- In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
- Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
- Alpha receptors are more abundant on afferent arterioles.
- This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
- This decreases blood flow to glomerulus, leading to decrease in GFR.
