Answer:
The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.
So, after 1 million years you will have 50% of the original substance remaining.
And, after 2 million years you will have 25% of the original substance remaining.
After 3 million years you will have 12.5% of the original substance remaining.
And after 4 million years you will have 6.25% of the original substance remaining.

Answer: You picked the correct answer, "They all inherited their traits from a common ancestor."
Explanation: Well, one I had a test on this question too and I got it right. Second, if all species shown have something in common (structures) than they most likely got it from a common ancestor.
The ribs because there Ike a shield to the organs
I found the exercise on the internet and these are the options:
"<span>a. gluconeogenesis begins
b. beta-oxidation increases
c. blood glucose levels fall
d. the liver produces more glycogen"
The option that's not likely to happen is "</span>the liver produces more glycogen".
The formation of glycogen by the liver happens after eating a meal with carbohydrates. The level of blood glucose increases, and insulin is secreted by the pancreas and will act by allowing glucose to enter the body cells. When the glucose enters the liver cells, insulin will also act on the liver by stimulating glycogen synthesis. This process continues to happen until glucose levels begin to decrease in the <span>post-absorptive state</span> and, therefore, insulin secretion also decreases leading glycogen synthesis in the liver to stop.
