Why is a countercurrent system a more efficient system for gas exchange?

Biology
1 answer:
solong [7]3 years ago
8 0

Answer:

A countercurrent system a more efficient system for gas exchange. Because water is viscous, this would require a lot of energy, so the counter-current system is a more efficient way of increasing the amount of oxygen diffusing into the blood. The unidirectional flow of water is another advantage.

I hope you helped^_^

zaharov [31]

Answer:

The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. ... Once the light reactions have occurred, the light-independent or "dark" reactions take place in the chloroplast stroma.

Alisiya [41]

Answer:

B. Virus.

Explanation:

Hello.

In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.

Best regards.

Why are metals good conductors of electricity but covalent compounds are poor conductors
Nataly [62]
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
