Answer and explanation;
-The insulin receptor itself has decreased kinase activity leading to fewer binding sites for singling effectors to become activated.
Therefore; the signaling effectors are less likely to be activated.
-Additionally,, feedback inhibition decreases signaling effector binding to receptor.
-The lack of activation of these initial signaling effectors prevents any subsequent steps from happening.
-We can thus conclude this by saying that higher insulin concentrations are necessary to obtain the same level of signaling leading to physiological effects that would exist in someone without type-2 diabetes.
-Also the requirement for higher insulin concentration means that the cells that respond to insulin are resistant to its effect.
Answer:
La química es la ciencia que estudia la composición, estructura y propiedades de la materia, así como los cambios que esta experimenta durante las reacciones químicas y su relación con la energía.
Explanation:
Answer:
a. Following an injury that breaks the surface of the skin. blood vessels dilate as a result of histamine release from mast cells and other damaged cells.
b. The blood forms a clot and upon drying, a scab forms a barriers between the body and the environment, while phagocytes work to clear the underlying debris from the wound site.
c. Blood vessels begin to re-grow into the wound while fibroblasts begin process of replacing the blood clot with Collagen
d. The remodeling phase then occurs as fibrosis and regeneration of tissues may continue for prolonged period of time.
Explanation:
Hello. Although you did not have all the answer options for the blanks presented in the sentences above, it is possible to conclude that the words in bold are the most appropriate to fill these spaces.
That's because when we cut ourselves, the blood vessels on the surface of our skin rapidly dilate, allowing a flow of blood to be observed. This dilation is accomplished by the release of histamine, which is released by mast cells, which are glands that regulate the immune response. At this point, it is important that any impuzera or microorganism, close to the wound site, is removed and this site undergoes cleaning. This is done by phagocytes, which are intended to prevent the cut from becoming the entrance to a bacterial infection.
Then the blood vessels begin to move and grow again across the wound, with the aim of covering this opening. In this comment, fibroblasts begin to apply collagen and replace the blood clot formed to prevent blood loss. Collagen will be responsible for maintaining the skin and tissues that will be rebuilt in the remodeling phase.
I have provided the options below:
a. 150
b. 225
c. 300
d. 450
e. 75
Answer:
150
Explanation:
Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.
Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2
Allelic frequency = 0.75.
Therefore, the percentage of the allele in the population would be given by
0.75^2 = 0.5625 = 56%.
And the total number of individuals with this allele in the population:
number of individuals = 56×300÷100
= 168 or
150 nearest figure.
Transcription in scientific genetics is used to describe the copying of the genetic sequence of DNA on messenger-RNA during expression of genes. On the other hand, translation is used to describe the use of the MRA to convert the gene sequence to amino acid sequences with the help of ribosomes.
