Answer:
What is a. A; A
Explanation:
Drop 1 struck the surface from direction A, and drop 2 struck the surface from direction A.
Ans ; It would have to be closer for it to be in a circular orbit twice as fast. One moon cycle would be 2 weeks instead of 4 so our months would have been based on 2 week cycles making for 24 months. Tides would be less synchronous between days and much more intense because of how close it would be. This would have left a very different land map. Tidal forces would force the moon to rip apart sooner than with it's present orbit creating an important ring system around earth earlier.

yes

The percentage of progenies with red eyes and spine will be 56.25%.
<h3><u>Explanation:</u></h3>
This cross will be just similar to Mendel’s Dihybrid cross where he crossed the pea plants considering two characters at once.
Here two characters that are taken into account are eye colour and presence of spine. The eye colour has two traits - red and brown. Red colour is dominant. The presence of spine has also two possibilities - presence of spine or absence of spine.
The allele denoting red eye colour is R and allele denoting brown eye colour is r. Similarly, the allele denoting presence of spine is S and absence of spine is s.
Genotype of the heterozygous parents = RrSs.
Gametes produced by the parents= RS, Rs, rS and rs.
So crossing them, we get the phenotypic ratio of red eyed spined : red eyed spineless : brown eyed spined : brown eyed spineless = 9:3:3:1.
So, the percentage of red eyed spined = 56.25%.
