Answer:A) The ocean is hypertonic to the erythrocytes.

Explanation:cells shrink when placed in an hypertonic solution.

This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.

The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.

In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell

Answer:

A and D

Explanation:

Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.

If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:

  • Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
  • The normal synthetase might be present but not in an adequate amount.
