A number of chipmunks die due to old age (pretty sure)
The amount of light and type of light is unchanged, so they are independent variables. The growth of the plants will depend if a few factors, so it is dependent. I’m not gonna lie, I have no clue about the color option. If you are using the same bean plants throughout, the color is independent so it would matter. If you are breeding them, it is then dependent on what genes they get. If this is a select all that apply question, I would suggest just putting A and B.
Answer:
B) 1/2
Explanation:
A sex linked trait is passed via sex chromosomes. Here the given trait is X linked recessive because female carrier is not possible for X linked dominant trait.
For X linked recessive trait:
Carrier female = XCXc
Affected male = XcY
Their progeny:
XC Xc
Xc XCXc XcXc
Y XCY XcY
Out of the sons, half will be not affected ( XCY ) and half will be affected ( XcY )
Hence, half of the sons will express the trait.

Answer:
No, cardiac muscle tissue does not exhibit recruitment.
Explanation:
The cardiac muscle tissue does not recruit cells to contract. The reason is that the cardiac muscle contracts all its cells at once and with the same force. It does not have to recruit other cells since it does not have to lift objects of different weights. The heart's contraction aims to pump blood and to do it rhythmically. The heart has a natural peacemaker, the sinoatrial node. The Sinoatrial node transmits an electrical impulse to all the heart to contract it all at the same time and continuously. For these reasons, the cardiac muscle does not need recruitment.
