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).
True. N.L Bowen hypothesized that minerals formed in two different ways. The first is a gradual, continuous fashion with minerals that have very similar chemical components. The second is through a sudden, discontinuous change in the mineral type.
B. Earth is tidally locked, while the moon spins on its axis.
C. The moon is older than Earth by approximately 300 million years.
D. Earth and the moon have nearly the same mass.
Answer:
A
Explanation:
It is believed that the moon was formed shortly (relative time) after the earth was newly formed. This occurred in a massive planet-sized collision that ejected a huge chunk of the earth out into space. The chunk, still within earth gravitational reach, began orbiting the earth becoming the moon. Both earth and moon are slightly more than 4 billion years old.
Answer:
A. Earth and the moon are nearly the same age.
Explanation:
These hypotheses are consistent with the evidence that shows rock from the moon and the earth have nearly the same age and composition.
It could be harmful to the ecosystem.
It may make additional types of medical treatments available.
It is more expensive than creating synthetic compounds.
It provides additional variety of known chemical compounds.
