Sickle cell anemia illustrated in the picture below is the result of a mutation. What is the likely cause of this genetic mutation?

Answers

There's no picture.

Sickle cell anemia results from a mutation in a gene called HBB, which contains the blueprint for cells to make part of a protein called hemoglobin. The hemoglobin protein is made up of two alpha chains and two beta chains.

Sickle cell anemia is the result of a point mutation, a change in just one nucleotide in the gene for hemoglobin. This mutation causes the hemoglobin in red blood cells to distort to a sickle shape when deoxygenated. The sickle-shaped blood cells clog in the capillaries, cutting off circulation.

Answers

Answer:

Energy

Explanation:

Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

If fertilization occurs which layer does the egg burrow into
a.myometrium
b.perimetrium
c.endometium

Answers

According to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.

What is endometium?

It is the tissue that covers or upholsters the uterine cavity whose function is to receive the fertilized egg when pregnancy occurs, that is, it allows the implantation of a fertilized egg, which will later transform into a new being.

For the endometrium to carry out its function, it has to undergo a series of morphological and functional modifications linked to the secretion of hormones by the ovaries so that at the time of greatest receptivity, the endometrium has the thickness and the nutrients necessary for a correct interaction with the embryo.

Therefore, we can conclude that according to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.
