Answer: D) constructive process
Explanation:
Deposition is the geological <u>process</u> in which sediments, soil and rocks are <u>added</u> to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, <u>building up</u> layers of sediment.

Consider the nest to be (0,0)
The bird first flew 40 km (20x2) up and then 45km (15x3) left
So the final coordinates would be (40, -45)
Answer: To eliminate bacteria that failed to take in the plasmid.
Explanation:
Research shows that plasmid DNA is only taken in by small percentage of bacteria in a large population.
Therefore, the need of growing transformed bacteria in the presence of ampicillin is very important. The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive.
However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.
Answer:
1.31 cM
Explanation:
Total offspring = 2205
Since two genes are involved, F1 progeny should have four types of combination. Out of them two are 17 and 12 which definitely means they are in lesser number. Since recombinants are always less than parental progeny in linkage, the given two types are recombinants.
Recombination frequency = (Number of recombinants / Total progeny) * 100
= [ ( 17 + 12 ) / 2205 ] * 100
= ( 29 / 2205 ) * 100
= 1.31 %
Map distance = Recombination frequency
Hence, distance between two genes = 1.31 cM
