Which of the following is not a difference between cardiac and skeletal muscle?
cardiac muscle cells quickly die in the absence of oxygen; skeletal muscle cells are better able to adapt to oxygen deficiency.
the plasma membranes of cardiac muscle cells interlock, but skeletal muscle fibers are independent.
cardiac muscle does not use the sliding filament mechanism for contraction; skeletal muscle does.
cardiac muscle cells contain more mitochondria than do skeletal muscle cells.

The correct option is this: CARDIAC MUSCLE DOES NOT USE THE SLIDING FILAMENT MECHANISM FOR CONTRACTION, SKELETAL MUSCLE DOES.

Explanation:

The muscles found in the heart are called cardiac muscles while the ones found in the skeleton are called skeletal muscles. Both muscles have some differences and similarities. One similarity between the two is that both of them are striated muscles. Also, both cardiac and skeletal muscles use the sliding filament mechanism for contraction.

The differences include the following:

1. Skeletal muscles are involved in voluntary movement while cardiac muscles engage in involuntary movement.

2. Cardiac muscles can not survive for long in the absence of oxygen while skeletal muscle can adapt to absence of oxygen.

3. Cardiac muscles cell have more mitochondria compare to skeletal muscles cells.

hi there!

answer: b. nucleolus

explanation: nucleolus is a structure in the nucleus are ribosomes are made.

hope this you!

have a nice day! : )

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
