Answer:
The tails
Explanation:
The tails of the layer reject water, making it harder for things to get in and out of the cell
Answer:
25%
Explanation:
The female with brown teeth had a father with normal teeth. Since normal teeth is a recessive trait, the father would have been homozygous recessive for the trait and would have transmitted one recessive allele to the female. Therefore, the female is heterozygous dominant for brown teeth.
Let's assume that the allele for brown teeth is X^B while the one for normal teeth is X^b. The genotype of heterozygous dominant female would be X^BX^b and that of the male with normal teeth would be X^bY.
A cross between X^BX^b and X^bY gives progeny in following phenotype ratio= 1/4 daughter with brown teeth: 1/4 daughter with normal teeth: 1/4 son with brown teeth: 1/4 son with normal teeth. Therefore, the probability of having a daughter with brown teeth is = 25%
The correct answer is fixed migration pattern.
Extinction means termination of last member of a particular species. This can be due to various factors. The reason could be natural or human interventions. The best characteristics of an organism to be less likely to face extinction are the fixed migration pattern. Migration of that particular species in a fixed pattern will make them adapt different environment. This saves the species from natural extinction. Even if the species of a particular geographical area dies the migrated species will be alive to breed and save the species from extinction.
