Salmon eggs hatch in fresh water. The fish then migrate to the ocean (a hypertonic solution) and, after several years of feeding
Ray Of Light [21]

Answer:

Letter C

Explanation:

Salmon have a physiological adaptation that allows osmoregulation to occur in two different environments (seawater and freshwater). There are specific molecules in the salmon gills that "pump" and "remove" Na and Cl ions. When at sea these molecules pump the ions out of the salmon's body and into freshwater, the same molecules remove Na and Cl from the water bringing it into the animal's blood.

sukhopar [10]
<h2>GREETINGS!</h2><h2>_____________________________________</h2>

<u>ANSWER</u><u>:</u>

<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>

Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.

<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>

the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.

<h2>_____________________________________</h2><h2>DIFFERENCES</h2>

1)      VOLUNTARY MUSCLES are under our control but INVOLUNTARY                 MUSCLES are not under our control

2)      VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles

3)      VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.

4)      VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.

5)      VOLUNTARY MSUCLES  require more energy. INVOLUNTARY MUSCLES require less energy.

if there were no suppression of dna replication between meiotic divisions but cytokinesis proceeded normally, what is the most l
sergiy2304 [10]
The answer is 4 diploid cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces <em>two haploid cells</em>.<span> Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no </span><span>suppression of DNA replication, then meiosis I would produce <em>two diploid cells</em>, and after meiosis II there will be four diploid cells.</span>
