Answer:
Essay on types of digestion
Explanation:
Digestion refers to the breakdown of large food molecules into small food molecules so that can be absorbed by the blood. There are two types of digestion i. e. mechanical digestion and chemical digestion. in mechanical digestion, the food is broken down into smaller parts physically with the help of teeth while on the other hand, in chemical digestion, food is broken down into small particles with the help of chemicals such as acids and enzymes. This chemical digestion is carried out in the stomach where different types of chemicals are present.
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:
From the Question A is the ANSWER

Explanation:
Answer: There re two different types of phenotypes in the offsprings that is Round yellow and Round green.
Explanation-
As per the Mendelian inheritance, Round shape and yellow color of pea are dominant over wrinkled shape and green color of pea.
According to the question, genotypes of parents are- RrYy ( heterzygous for round and yellow) and RRYy ( homozygous for round and heterozygous for yellow).
The first parent can produce four different gametes that is RY, Ry, rY, ry whereas the second parent will produce only two types of gametes that is RY and Ry.
When they are crossed, they will produce two different phenotypes in the offsprings.
