How does the change in the estrogen level corrrespond to the gradual thickening of the uterine lining

Biology
1 answer:
vfiekz [6]2 years ago

<span>The gradual thickening of the uterine lining also called Endometrial Hyperplasia is often caused by having excess estrogen without enough progesterone to balance it. During menstruation, the estrogen causes the lining to thicken in preparation for pregnancy. When the progesterone is made during the second half of the cycle and the progesterone levels drop, the lining is shed. And if the ovulation didn’t occur, progesterone is not made and the lining is not shed properly, the lining will keep on building gradually that may lead to cancer in some women.         </span>

After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of african ancestr
zhannawk [14.2K]
After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of African ancestry. This is supported by two mechanisms: heterozygote advantage and gene flow.

Heterozygote advantage
When an allele is said to be heterozygous, it is carrying one copy of a gene. For example if one carries a copy of sickle cell allele, it will stay in the population even after many generations — natural selection will not be able to remove it and it will be passed on through generations. So, having one copy of that allele is advantageous but not deleterious.

Gene flow
With humans migrating throughout the different parts of the world, sickle cell allele is passed from one person to another or in different populations. It is actually advantageous to have one copy of this allele especially if there’s malaria in the area, which the allele is resistant.

What is meant when we say that organisms evolve?
andreyandreev [35.5K]

Answer:

Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
