Answer:
Active transport
Explanation:
The pumping of sodium ions out of the cell into the environment where there is a lower concentration is achieved through active transport. Active transport is the movement of molecules or ions against a concentration gradient across living cell membranes with the utilization of ATP. Active transport takes place through carries located in the membrane.
Hello! This is a very interesting sea animal to study. So, most starfish have five arms that radiate from a central disc, but the number varies with the group. Luidia ciliaris has seven arms, members of the Solasteridae have ten to fifteen while the Antarctic Labidiaster annulatus can have up to fifty. It is not unusual in species that typically have five arms for some individuals to possess six or more through abnormal development. That’s really all I know about the anatomy of a starfish. I hope this helps.
If you have further questions please post them in comments. Have a great night!
