Where is the options ???!!!
Answer:
A
Explanation:
The correct answer would be that <u>the availability of food resources for black mice and brown mice will decrease.</u>
<em>Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.</em>
There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.
The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.
<u>The only correct option is A.</u>
<span>Using a genetic cross, we can look at the following
A = brown a = White, B = Tall, b = small
With the capital letters being the dominant allele
A a
B AB aB
b Ab ab
The allele we are looking for is Ab which as 1/4 chance
To work out how many are in 2/6 also (1/3)
we do 1/4 x 1/4 x 1/4 = 1/64</span>
This is an example of vestigial structure.
Vestigial structures are structures (cells, tissues and organs) found in an organism that has lost most or all of its primitive function through evolution. The vestigial structure has performed vital functions in the organism in the past but as there are changes in species as a result of natural selection, the structure became less important until it no longer functions. A reduced nonfunctional digit on the paws of dogs known as a dewclaw is an example of vestigial structure.
