Answer: They would die, or go insane

Explanation: First off, they need to have a steady food supply to maintain society. If, lets say, the food ran out, then everyone would die as they were isolated and had no other food source. Since the human body needs to have interaction, if a certain group of people were isolated, they would most likely also go insane due to the lack of no other people. Of course, the info you gave was very vague, so I couldn't really give a good answer, so yeah

In guinea pigs, smooth coat (S) is dominant over rough coat ( s ) and black coat (B) is dominant over white coat (b). In the cro

Answer:

9 out of 16 offsprings

Explanation:

This question involves two genes in guinea pig; one coding for coat texture and the other for coat color. The alleles for smooth coat (S) and black coat (B) are dominant over rough coat (s) and white coat (b).

In this question, two heterozygous guinea pigs were crossed i.e. SsBb × SsBb. The gametes produced by each parent is as follows: SB, Sb, sB, sb. Using these gametes in a punnet square (see attached image), the proportion of offsprings will be:

Smooth black coat (S_B_) = 9

Smooth white coat (S_bb) = 3

Rough black coat (ssB_) = 3

Rough white coat (ssbb) = 1

Hence, according to this question, 9 out of 16 offsprings will have a smooth black coat on average.

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere
