Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:

  • The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.

Explanation:

<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .

Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :

  • Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
  • Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).

How do temperature and salinity affect deepwater currents?
WITCHER [35]

Answer: They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

The temperature and salinity has a major impact on water current of oceanic water. The warm water is usually less denser than colder water, so it remains at the surface of water body, whereas the colder water being more in density remain in a depth. The salinity of cold water is more than the warm water.

According to the above explanation, they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them is the correct explanation.

They discovered that base pairing nucleotides must be; adenine and thymine; and cytosine and guanine. These base pairs are held together by a hydrogen bond, atype of chemical reaction that s easy to break and easy to reform. The statement is “DNA is a double helix made of two strands linked together with hydrogen bonds.”</span>

Given parameters:

Speed of the bird  = 12.5m/s

Speed of the wind  = 4.5m/s

Unknown:

Speed of the bird when it flies with the wind = ?

Solution:

The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.

  Speed of the bird with wind  = 12.5m/s + 4.5m/s  = 17m/s
