Answer:
Expecting that the skeletal muscles of frog is like human beings (as they are vertebrates). The end drawn from this supposition that will be that the A band (thick fiber) stays unaltered in any event, during compression and the I band (flimsy fiber) contracts. So from the given data following outcomes are acquired;
A band before = [2.0um]
I band before = [2.0um]
A band after = [2.0um]
I band after = [1.0um]
im pretty sure the answer is going to most likely be A: decomposing dead plants and animals

Answer:
The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration.
