Answer;
-Hot desert biome
Explanation;
Hot Desert is characterized by very little rainfall or a lot of rain in a very short period. The soils are often salty because minerals do not get washed away. Thus, the climate is characterized by a very little precipitation.
-Plant adaptations: There are few plant species. these plants are adapted to resist drought and store water. For example; Spiny cacti that have thick, fleshy stems that conserve water are common. Their roots extend metres away from the plant to absorb water. Other plants have small, thick, waxy leaves that also store water. Many plants have spines or produce chemicals that protect them from being eaten.
B. essential
We cannot store up amino acids on our body, but we can have amino acids through consumption of food. These amino acids of which the body cannot make is called as essential amino acids.
Answer:
Example of the Epistasis in plants is observed in the "summer squash".
Explanation:
Epistasis refers to a gene interaction in which one gene is masked by the other gene and affect the phenotype. The gene which masks the other gene is known as the epistatic gene and the gene which is being masked is known as the hypostatic gene.
The epistasis gene effect is observed in which more than one gene controls the same phenotype.
The example can be observed in the summer squash fruits in which more than one gene controls the color of the fruit.
The summer squash can be controlled by the white allele (W), Yellow allele (G) and the green by the recessive form of the w and g. If the W gene is present than it masks the other allele and thus white colour becomes dominant and is considered the case of the dominant epistasis.
