How does active transport help the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions

Biology

kotegsom [21]3 years ago

Atlantic Cod is a marine fish. The fish has less salt in its internal body while the salt concentration in the sea water in which the Cod lives is high. Thus through the process of osmosis ( a process in which an element moves across a permeable membrane from regions of high concentration to the regions of low concentration) the salt moves from the ocean into the fish body. In such scenario the metabolism of the fish body gets disturbed, and there is an urgent need to remove the excess salt with the help of Kidney (through extremely concentrated urine) by going against the concentration gradient in order to maintain the homeostasis.

Answer:

The Atlantic cod is fish of Atlantic ocean that continuously drinks water to fulfill its needs, however, this fish is not an ocean osmoconformer. The concentration of the salt is less than the seawater in the fish. It removes water by the process of osmosis which is active transport to the ocean.

The homeostasis is maintained by these fishes by removing excessive salt from the body and as it moves against the gradient that is active transport, this process requires energy. These fishes excrete urine in a very concentrated form.

What causes formation of the fertilization envelope?
Sonja [21]

Answer:

Sperm-egg interaction

Explanation:

The formation of fertilization envelope is well-studied on the model system- sea urchin. It has been shown that, the fertilization envelope is formed after the initial sperm-egg interaction from the egg surface vitelline envelope and the paracrystalline protein fraction which is derived from cortical granules. Secretion from cortical granules, prevents polyspermy.

Which structure is at work when the body deals with reflex actions?
Ne4ueva [31]

Answer:

spinal cord

Explanation:

Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.

Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.

Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.  

Hence, the correct option is spinal cord.

a scientist conducted an investigation about the effects of diet on disease resistance in rats and made surprising observations.
devlian [24]

Answer: The scientist will perform another investigation in order to find out the role of certain genes in disease resistance.

Explanation-

As per the information given in the question, a mice having mutation in ear depicts same pattern of resistance when compared to another mice having normal ears. This indicates that the genes responsible for resistance are not related to genes that result in ear formation.

Therefore, to find out the effect of diet on disease resistance in rats, the scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
