A student compares two different proteins. The student notices that the primary structures differ in both the number
of amino acids and the sequence of amino acids. Based on this information, what can the student infer?
A)
The two proteins have different functions.
B) The two proteins would have the same shape.
C) The two proteins were coded by the same gene.
D)The two proteins do the same type of job inside of the cell.

A.The two proteins have different functions.

Explanation:

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
