Horses and zebras can be bred to produce a zorse, which is infertile. Which is most likely the reason zebras and horses are cons
andrew11 [14]

Answer:

The correct option is B) Their offspring cannot breed.

Explanation:

Organisms belonging to the same species require the ability to breed and produce fertile offsprings. If two organisms breed to produce infertile offsprings, then they are not considered to belong in the same species. Infertile offsprings do not have the capability to reproduce. The breeding between a horse and a zebra produces zorse, which is sterile. This depicts that both the zebra and horse belong to different species as they cannot produce a fertile offspring.

The ___ biome is characterized by moderate temperatures and high quantities of precipitation.
diamong [38]

Answer:

The temperate rain forest.

Explanation:

Temperate rain forests are similar in structure and precipitation amounts to a tropical rain forest. The difference is in the location and temperature of each. Tropical rain forests are located on and near the equator, and are incredibly warm and humid, with large amounts of precipitation. Temperate rain forests are found north of the Tropic of Cancer and have moderate temperature and humidity levels. The way to remember the difference is to notice that Temperate is a combination of 'moderate' and 'temperature' and can be said to mean "moderate temperature". I hope this is the answer you were looking for!
