Answer:
B.
Explanation:
Biome is a combination of two words 'bio+ome,' which means life and its specified nature.
In simple terms, biome can be defined as a naturally occuring of a large number of flora and fauna that occupies major part of nature. Ecologists, who study biomes, defines it as a large community of flora and fauna that resides in the same ecology or environment. Biome not only consists of flora and fauna but also its abiotic factors such as the adaptation of animals in different environment.
Therefore, option B is correct.
Answer:
The correct option is D. Crossing over and independent assortment are the causes of genetic variation.
Explanation:
In the process of meiosis, crossing over is a phenomenon through which exchange of genetic segments takes place among the homologous chromosomes.
The process of independent assortment describes how different genes assort differently during meiosis.
Both the process of crossing over and independent assortment are the basis of the genetic variations seen in the world.
The answer of the given description above is CORTISOL. Cortisol is a hormone and this is the one that stimulates the breakdown of fats in the adipose tissues. Once these are broken down, the fatty acids are released to the blood. Basically, when there is an increase cortisol in the body, this can help one lose body fats. Hope this helps.

Answer:
frequency of dominant and recessive alleles - 0.6, 0.4
frequency of individuals with dominant, heterozygous and recessive genotypes - 0.36, 0.48, 0.16
Explanation:
Given -
Short ears (S) is dominant over floppy ears.
Total population of rabbits 
Population of rabbits with floppy ears 
Population of rabbits with short ears 
Frequency of rabbits with floppy ears is equal to
Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by 
Thus,
Thus,
Frequency of rabbits with short ears only
Frequency of heterozygous rabbit (Ss)
