Answer:

''The sun uses its gravity to pull the planets towards it''

Explanation:

These two statements describes Newtons laws of Motion and Gravity. With statement 1, which shows the motion of the planets constantly changing due to the attraction of the sun. When the planets come close together to the sun, its orbital speed increases while on the other hand, when the planets goes farther from the sun, its orbital speed decreases. The statement 2 indicates that sun attracts other planets due to its gravity which allow them to move in a curved.

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
spayn [35]

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.
