Which of the following is NOT a difference between cardiac and skeletal muscle?
IrinaVladis [17]

Answer:

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.

At which of the following temperatures is the speed of a given chemical reaction the fastest?
Rashid [163]
There are many factors that affect the rate of chemical reactions and temperature is one of them.
Typically, the higher the temperature of a chemical reaction the faster the reaction occur, that is, the temperature and the rate of chemical reaction are directly related. This is due to the fact that increasing the temperature of the reaction increases the kinetic energy of the reacting particles and thus they are able to move faster and the reaction also occur faster. Thus, from the options given, the correct answer will be D [40 degree], this is because, it is the highest temperature out of all the options given.
