D, because all of the other options say that humans do not cause it, or that it is based on false data.
The correct answer is sarcomere.
A sarcomere refers to the fundamental unit of striated muscle tissue. It is the reiterating unit between the two Z lines. The skeletal muscles comprise tubular muscle cells known as muscle fibers or myocytes that are produced in the procedure called myogenesis.
When the muscle fibers of a motor unit attain an impulse, it instigates a response in each sarcomere between the myosin and actin filaments. This response leads to a start of a contraction and the sliding filament theory.
Answer:
The Digestive System absorbs nutrients from food and delivers them to the bloodstream, where the Circulatory System transports them to their destination. Filters waste from meals and transports it through the intestines and out of the body.
Explanation: Answer above
Answer:
energy rich molecules
Explanation:
Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
Triglycerides and cholesteryl esters are transported in the core of plasma lipoproteins. The intestine secretes dietary fat in chylomicrons, lipoproteins that transport triglyceride to tissues for storage. Dietary cholesterol is transported to the liver by chylomicron remnants which are formed from chylomicrons.
