C. When there is an equal number of molecules on each side
Long bones have a tubular shaft and articular surface at each end. The major bones of the arms and the legs are all long bones.
Short bones also have a tubular shaft and articular surfaces at each end but are much smaller. The short bones include all of the metacarpals and phalanges in the hands, the metatarsals and phalanges in the feet, and the clavicle.
Flat bones are thin and have broad surfaces. The flat bones include the scapula, the ribs, and the sternum.
<span>Irregular bones are irregular in size and shape and are usually quite compact. They include the bones in the vertebral column, the carpal bones in the hands, tarsal bones in the feet, and the patella.</span>
Answer:
The process of respiration can take place in the presence as well as absence of oxygen. Hence, respiration is of two types: 1. Aerobic respiration and. 2. Anaerobic respiration.
Aerobic respiration is far more energy-efficient than anaerobic respiration.
Aerobic processes produce up to 38 ATP per glucose.
Anaerobic processes yield only 2 ATP per glucose.
Explanation:
Answer:
Osmosis
Aquaporins
Explanation:
This is because osmosis is the movement of solutes from a region of lower concentration to a region of higher concentration through a permeable membrane.
Aquaporins are lipid bilayer and water pores that serve as channels of transmembrane proteins that allow water to cross the membrane very fast, and they play vital roles red blood cells, plant cells and kidney which help to reduce water lose.
