In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?

Answers

Answer:

This question is incomplete, the complete question is as follows:

- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.

What percentage of offspring are expected to be chestnut?

The answer is 0%

Explanation:

This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.

According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;

BB - B only

bb - b only

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

Bb, Bb, Bb, Bb

All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0%  of offspring are expected to be chestnut.

Answer:

the process of turning from liquid into vapour

Answer:

Evaporation is a surface phenomenon, which implies that the process only occurs at the surface of the liquid. During evaporation, the molecules of the liquid that are present at its surface overcome the intermolecular forces of attraction to break away from the liquid and escape into the atmosphere as a gas (or vapour).

Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards?


A. High daytime temperatures allow them to grow as large as the food supply will allow.


B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.


C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.


D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.

Answers

Answer:

A. High daytime temperatures allow them to grow as large as the food supply will allow.

Explanation:

Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.

Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.
