Answer:
The majority of the carbon dioxide we exhale is produced in the cell during the process of respiration.
Explanation: Carbondioxide is a waste material which is produced in the process of respiration. In respiration, glucose molecules is broken down for releasing energy with the help of oxygen molecule which produces carbondioxide, water and energy in the form of ATP. Carbondioxide is removed through lungs and energy is used by the cell.
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.
Answer:
A is preferable as the answer
Answer:
26%
Explanation:
If a DNA strand is made up of 26% Cytosine, what percent will be Guanine?
C -> G
they go to each other so the Cytosine will be the same percent as Guanine and vise versa
