<h3><u>Answer;</u></h3>
He crossed two pure breeds
<h3><u>Explanation;</u></h3>
- <em><u>F1 or the first filial generation is the first generation of offspring produced by crossing a set of parents to help show what genes will be inherited from crossing pea plants. Therefore, the F1 generation consist of or offspring from the parents.</u></em>
- <em><u>Mendel performed a true breeding cross, meaning he crossed one homozygous recessive for a trait and one homozygous dominant for the trait. This gave rise to the heterozygous dominant offspring. </u></em>
Answer:
In these experiments the control group is compared with the comparison group.
The control group will sometime be in the presence of carbon dioxide, and will be controlled, where the analyst or researcher will take an expert position and then will compare it evolutionarily with the comparison group that the ideal would be that there is not ever a carbon dioxide
Explanation:
If we have two poison ivy research groups that are representative of the poison ivy that the researchers are looking to investigate the results will have much better credibility and will be more reliable.
On the other hand, the comparison of the two groups makes it possible to rigorously analyze whether or not poison ivy grows in the presence of this gas.
This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
