In the crayfish's nerve cord, it is the combination of the two nerves that lead from the brain to form the ventral nerve cord which runs down the abdomen. It is important for sending signals from the ganglion to the appendages and muscles. While the rat's spinal cord it runs along the dorsal or back, rather than the front, and it is important for transferring neural signals between the brain and for the rest of the body.

ValentinkaMS [17]

Answer: actively pump water back into their cells to counter its loss due to osmosis.

Explanation:

The salt lake is the hypertonic solution that means it exhibit the high concentration of salt as compared to what is present in the cells of the organisms. Thus the cells of animals or plants in the hypertonic solution shrinks as they will loose water. The water moves from the higher concentration to the lower concentration.

The brine shrimp cells will shrink in the hypertonic solution of the salt water. Thus the shrimp will actively take or pump water inside the cell to counter balance the loss of water caused due to osmosis.

bagirrra123 [75]

Answer:

B. Dehydration

Explanation:

Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.

Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.

For example: RCO2H + R′OH ⇌ RCO2R′ + H2O

In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH

The reaction is showing dehydration because two molcules are combined aand  water molecule is eliminated from the reactant.

Hence, the correct option is B. Dehydration.
