In horses, black (B) is the dominant color; brown (b) is the recessive color. Consider the cross seen here, between two black horses (Bb). What is the probability that these two horses will have a foal that is brown?A) 0%
B) 25%
C) 40%
D) 50%

Answers

Answer 1
Answer:

Answer: The correct answer is 25%.

Black color (B) of horse is a dominant trait over brown (b) color, which is a recessive trait. As we know that dominant gene masks the expression of recessive gene, therefore brown horse color will only be produced in the genpotype bb.

On the other hand, there are two possible genotypes for black horse color that is BB and Bb.

As per the question, parental genotypes are Bb and Bb. When they are crossed, they will produce 25 % foal with brown color (bb).

Refer punnett square.

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer or soap and warm water for two minutes; then they dried their hands with a paper towel. The standard of comparison was rubbing hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. The sanitizer advertisement claimed to kill bacteria more effectively than any soap. After washing, hands were swabbed and then the swab applied to a culture plate and incubated. Finally, the bacterial cultures were counted. Students using the antibacterial santizer had the lowest bacterial culture count. What is the control in the experiment? A) washing with soap B) rubbing vigorously C) the time: two minutes D) rubbing hands in warm water

The cuticle is used fora. water conservation.
b. protection from predators.
c. photosynthesis.
d. gas exchange.

Answers

Answer:Water conservation

Explanation:

In some of the higher plants there is a presence   of hard cutaneous part on the leaves. Cuticle is a water-impervious layer which covers the epidermal cells of the leaves.

It aids in limiting the water loss by the leaves. It is the part of plants that faces the external environment by hindering the water loss.

This part is made up of waxy coating, which is water repellent known as suberin.

It helps in the water conservation as it limits the excess loss of water from leaves.

A, the cuticle is used for water conservation.

What abiotic factors describe the desert biome climate?a.
four distinct seasons, a temperature range from just below freezing to 70º F, almost 14 inches of rain in the winter months and more than 18 inches of rain in the summer
b.
warm temperature year round, very long dry winter and a very wet summer, a temperature range of 68° to 86° F, annual precipitation of 10 to 30 inches
c.
subarctic and cold climate, long, severe winters, average yearly rainfall is 15 to 20 inches
d.
extremely low humidity, less than 10 inches of rain per year, high temperatures during the day, frequently windy

Answers

Answer: The correct answer is D) Extremely low humidity, less than 10 inches of rain per year, high temperatures during the day, frequently windy  .

Abiotic factors include the non living components of the environment.

For example- Temperature, humidity, and rainfall.  

Desert biome is mainly considered as a part of drylands. It is characterised by extremely low humidity. Average rainfall in this biome is less than ten inches. This results in scarcity of water. It experiences extremely high temperature and is frequently windy.

Example of desert biome- Thar desert in Rajasthan.

Thus, option D) correctly describes the climate of desert biome.



 



The answer is D. Desert biomes have extremely low humidity, less than 10 inches of rain per year, high temperatures during the day and frequently windy. Abiotic factors are the chemical and physical factors that influence the environment. For instance, soil, temperature, and humidity.
