Answer:
llbb
Explanation:
<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>
The dehydration is a very common problem seen in elderly individuals. At an elderly age, all the body functions are diminished, which lead to reduction in thirst and body's ability to obtain water. That is why, the elderly people are very susceptible to dehydration.
In order to remain healthy, a person must take 2.5- 4 litres of water per day. In males, the water is required more than females. So, for males, the adequate intake (AI) of water should be in between 3-4 litres per day.
