Nuts are a good source of vitamin E. <br> a. True<br> b. False
mixer [17]
Nuts indeed are a good source of vitamin E. This is true. However, when talking about nuts we have to consider that not all nuts have the same nutritional information nor do all of them have plenty of vitamin E. While we can say this for most, it is necessary to be wary of making such statements.

How would the contractile vacuole of a freshwater amoeba respond is the organism was placed in seawater
morpeh [17]

The major function of the contractile vacuole of amoeba is osmoregulation. The solute concentration found in the cell of amoeba's cytoplasm is more than the solute concentration in the freshwater that surround the external part of the organism, thus, water enter the cell through osmosis. The contractile vacuole collect the excess water and expel it through an opening in the cell membrane. By doing this, the contractile vacuole maintains the water balance in amoeba. This how the contractile vacuole normally operate.

In a situation where amoeba is placed in seawater, then water from the cell cytoplasm will rush out of amoeba cell, because of the higher salt content of the surrounding medium. The contractile vacuole will respond to the situation by increasing its contraction and pumping water out the cell in an accelerated manner, this will lead to the shrinking of the cell.
