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.
Hydrolysis is the reaction that stems from the breakdown of large molecules by the enzymatic addition of water. Hydrolysis is step leading to the degradation of the substa…nce. It is a chemical reaction in which a molecule of water is added to a substance.
Answer:
20 minutes
Explanation:
Divide distance by speed to get time
D/S = t
350/17.5 = 20
(Just an fyi you posted this in biology)
Im pretty sure the answer is d but not 100% sure
Answer:
So basically, when the osmometer is, the solution in the beaker is supposed to be hypotonic and relative to the solution in the dialysis bag. So when that situation occurs, the net movement of water is transferred into the bag. As the water slowly / hastily moves into the bag, the varying level of pressure is generated which forces the water to move up.
