Martina does not think cross species breeding should be allowed. Which of the following facts best supports her opinion? A) Mules are stronger and have more endurance than horses.
B) Genetically engineered proteins can help fight disease.
C)Quarter horses bred to compete in rodeos are fast and strong.
D) Mules cannot reproduce because they have an odd number of chromosomes.

Answers

Answer:

(D). Mules cannot reproduce because they have an odd number of chromosomes.

Explanation:

Cross species breeding may be defined as the process of breeding between two different species. For example, Mule is obtained by the breeding between male donkey and female horse.

Mules have odd number of chromosomes and they are sterile. This is because, odd number of chromosomes leads to non-disjunction and formation of abnormal chromosomal separation during gamete formation. Due to this, non-functional gametes are formed during meiosis and mules cannot reproduce.

Thus, the correct answer is option (D).

How does the suns energy cause a hurricane to form

Answers

The sun heats the land and oceans unevenly, creating areas of upwards and downwards moving air as well as pressure differences. This causes air to flow from one area to another. For hurricanes the sun heats the ocean, causing some water to evaporate. The water vapor powers convection in storms which can then strengthen and organize to form hurricanes. Hope this helps:)
