Describe how surface currents in gyres redistribute heat between the equator and the poles.

Biology
1 answer:
mafiozo [28]3 years ago
6 0

Warm surface currents flow out of ocean gyres from the tropics to higher latitudes, and cold surface currents flow from colder latitudes toward the equator. The oceans redistribute heat from high to low latitudes by moving warm water from the equator toward the poles.

An example of the role of cultural practices shaping natural selection on genes that affect human health concerns
kaheart [24]

Answer:

The correct answer here is D) None of the above

Explanation:

Lactose intolerance and sucrose intolerance in themselves are not practices but side effects of practices that affect health concerns.

For instance, research shows that cultures with a long history of dairy farming and milk drinking or at least a history of drinking milk have a much higher likelihood to be <u>lactose tolerant</u> than those who don't. And when they can tolerate lactose their bodies take note of this and records the same in their genetic databank.

Cheers!

Which is not an impact to the ecosystem after a drought?
Nadya [2.5K]

Answer:

A. Floods will wipe out all the vegetation

Explanation:

Drought is an environmental condition characterized by scarcity of water. Less rainfall and reduced ground water levels facilitate drought like conditions. In the event of drought, animals face difficulty in finding food and water and thus are forced to migrate to other areas. However, flood is exact opposite to drought. It is caused by excess rainfall or increase in water level which destroys the ecosystem. It is not a characteristic of drought.

Suppose that in another world, DNA does not undergo semiconservative replication, but instead a conservative mechanism is used.
Liono4ka [1.6K]

Answer:

c. ¼ heavy, ¾ light

Explanation:

DNA replication follows semi conservative model which means that both the strands separate during replication and the newly formed DNA molecule has one old and one new strand. If instead of semi conservative, conservative mechanism is used, old strands will not separate from each other and the two newly synthesised DNA strands will come together to form a DNA molecule.

Here the cells were first grown in heavy 15N medium so all the DNA molecules had 15N and thus were heavy. Then the cells were transferred to 14N medium where only lighter 14N were available for replication process.

In first generation, 14N DNA molecules were synthesised from 15N DNA molecules so 1/2 DNA molecules were 15N and other half were 14N. In the second generation, 14N molecules will give rise to new 14N molecules and 15N molecules will also give rise to 14N molecules hence 1/4 molecules will be 15N (heavy) and 3/4 will be 14N (light).
