"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.
The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.
Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.
The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).

Answer is option A.
A protein deficiency causes such diverse symptoms because immune, nervous, and muscle system cells require proteins for structure and regulation.
Proteins are the building blocks of bones, muscles, cartilage, skin, and blood. They also help in transporting oxygen, helps in blood clotting during injuries etc.
Vaccine, bacteria, pathogens, cells, toxins, antibiotics. In that order vaccine being first
Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water
Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.
To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.
I think A is the answer its hard to explain but i hope this helped.
