True, this is because Darwin realised that organisms best suited to their environment are more likely to survive and reproduce, passing on their characters to their offsprings.
First, to answer this question, you need to draw a Punnett square. So you put the homozygous short alleles (tt) on top of the square, and the heterozygous tall alleles (Tt) on the left side of the square (or vice versa, it doesn't really matter).
When you create the Punnett Square, you then perform the cross between the two plants' alleles. I cross t with T and that gives me Tt. Same with the next one, t and T becomes Tt. Then, I cross t with t and that gives me tt. Same with the next one, t and t becomes tt.
So, the answer here would then be c. 50 percent Tt, 50 percent tt. You might say, well, couldn't answer d also work? Answer d could only work if the question was asking for the phenotypic ratio of the offspring. Then you could say 50% tall, 50% short. But the question asks for the genotypic ratio, so it would instead be c. 50 percent Tt, 50 percent tt.
Hope this helps!
Answer:
Layer D
Explanation:
Layer D would be the oldest form of undisturbed rock. This would mean that since it is the oldest, it will be <em>least</em> similar to the present day form of that organism.
"If I heard a herd of elephants talking to one another and being together regularly, I would capture their noises. Then I would play them into the ground at a separate spot far away from the herd of elephants. I would observe the elephants' reactions while I recorded them by playing various recordings through the ground (ex. if they freeze in place when they feel the vibrations, how they react afterwards, etc.). To compare and analyze the elephants' behavior, I would record this information and repeat the procedure several times."
Behavior- The reactions of a complete live organism to internal and/or external stimuli are internally coordinated behaviors.
