Explanation / Answer

1. p = dominant condition
q = recessieve condition

p+q = p2+2pq+q2 = 1.

q2 = 100-60 = 40% => 40/100 = 0.4.
q2=0.4 => q = sqrt(0.4) = 0.63

as p+q = 1, p = 1-q => p = 1-0.63 = 0.37.

The proportion of heterozygous individuals = 2x 0.63 x 0.36 = 0.48.

So, the answer is D) 0.48

2. The answer is C) Ecosystem

3. The answer is C) Protocell

4. The answer is B) RNA

5. The answer is A) Population

6. The answer is A) Order.
