The answer is option D "Machines have replaced much of the manual labor once needed to run a farm."

Explanation:

* Progress in Engineering: This simply means how technological machines like heavy tractors which are now used and are helpful in farming are  evolving, meaning they are being used in a larger quantity now.

* Natural Environment: This is the normal way of life or doing things which individuals find themselves practicing in a particular society and at a particular point in time.

A fruit fly population has a gene with two alleles, A1 and A2. Tests show that 70% of the gametes produced in the population con
IceJOKER [234]

Answer:

Option C

Explanation:

Given ,

A1 allele is carried by 70 % people

Let us assume A1 s dominant genotype

This means p= \frac{70}{100} = 0.7

Thus, frequency of allele in the given population is 0.7

It is also given that the population is in Hardy-Weinberg equilibrium thus

p+q=1\\0.7+q=1\\q = 1-0.7\\q= 0.3

Frequency of fruit fly with genotype A2A2 will be

q^2\\= (0.3)^2\\= 0.09

As per Hardy-Weinberg's second equation of equilibrium

p^{2} + q^{2} + 2pq = 1\\0.49+0.09+2pq = 1\\2pq = 1-0.49-0.09\\2pq= 0.42

Hence, option C is correct
