Sperm tails in the fruit fly Drosophila bifurca can reach up to 6cm long, which is over 20 times the length of the organism itse

lf. Because the tails are so long, they aren’t able to provide the swimming force that other sperm tails are used for. Please provide a hypothesis as to why the fruit fly sperm has evolved to be so long.?

Explanation:

The length of the sperm in a few species is much larger or giant than the size of the animal-like observed in the <em>Drosophila bifurca. </em>

In this fruit-fly, the tails of the sperm are too long which could be accounted for many reasons:

1. The sexual selection prefers the long tails over the small tail.

2. The large sperms can displace the small sperms in the female reproductive organ.

3. The female reproductive organ increases the promiscuity of the large sperms that is favour the large sperms over the small sperms.

Which group of air pollutants tend to cool the atmosphere because they reflect more sunlight back to space thus reducing incomin
kondaur [170]

Answer:

D. atmospheric aerosols.

Explanation:

<em>Atmospheric aerosols are tiny particles that float in the air. These particles could be liquid or solid and are usually suspended primarily by direct emission into the atmosphere or secondarily by condensation process. </em>

Atmospheric aerosols have numerous effects on the biotic and abiotic factors of the environment. They alter air quality and impact human health in some cases, they can reduce atmospheric visibility, and they also reduce the amount of radiation that reaches the earth by scattering or reflecting some of the radiations from the sun back into space, leading to cooling of the atmosphere.
