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.
b. protection from predators.
c. photosynthesis.
d. gas exchange.
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.
You can determine the approximate size of the DNA.
Answer:
(CFC) production has been linked to an increase in the occurrence of skin cancers caused by holes in the ozone layer.
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
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.
