Answer:
A) 48
B) 96
C) 48
D) 48
Explanation:
Attached is a table summarizing the number of chromosomes and chromatids in the different stages of mitosis and meiosis in humans who are described as 2n = 46.
For the organism which is described as 2n = 48, substitute 46 in the table for 48 to get the appropriate figures.
The answer is NO. This is because different environments require different adaptations. A desirable trait in one environment may be inconsequential or detrimental in another environment. This is the reason also why evolution is continuous as natural selection acts on traits of a population to ensure desirable traits are retained with changes in the environment in a dynamic world.
The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.
