Answer:
<em>The water vascular system of echinoderms </em><em>functions in locomotion and feeding</em>.
Explanation:
Echinoderms have a unique vascular aquatic system called the <u>ambulacral system. </u>
The ambulacral system refers to a net of fluid-filled channels derived from the coelom with functions related to gas exchange, feeding, stimuli reception, and locomotion. This system acts as a hydro motor apparatus.
The opening to the exterior of this vascular system is through an opening known as madreporite. This structure is united to the circular channel that surrounds the animal´s mouth and from where five radial channels emerge and extend along each arm. Water runs through these structures and makes it possible the gas exchange, feeding, locomotion, and other functions. By hydrostatic pressure, little tubular feet are protruded and retracted and help the animal to move.

is important that antibodies have a symmetrical quaternary structure to create
two identical binding sites for antigens. An antibody is a relatively large
protein having a Y-shape. Plasma cells produce antibodies which are then used
by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody
is able to recognize the antigen of the pathogen. It binds with it either to
neutralize it directly or “tag” the microbe for future attack by other parts of
the immune system. </span>
Answer:
It will lose weight
Explanation:
The pyruvate is the product formed by the process of glycolysis by the breakdown of the glucose-mediated by enzymes.
The process of glycolysis take place in the cytosol therefore for further processing or stages of respiration, the pyruvate has to enter the mitochondria which occur through the (H+)/pyruvate symporter.
In the given question condition, if the symporter is blocked then the pyruvate will not enter into the mitochondria as a result of which less ATP will be produced. So the body will use some other sources which can form the pyruvate which can easily enter the mitochondria.
Therefore, the body will begin to lose weight.
