In my opinion, the best answer among the choices listed above is option D. The reason why scientists use models because they can <span>represent things that are too small to see. Models are used to describe and explain certain phenomena. Hope this answers the question.</span>
Answer:
C) all chinchilla
Explanation:
As we know that dominance of alleles for the coat color in rabbits goes like this:
C+ > Cch > Ch > C.
- The allele for full colour or agouti is designated as C+.
- Allele for mutant coat color silvery- gray coat-chinchilla is Cch.
- Allele for “Himalayan” coat is called ‘Ch
- Albino rabbits have whole white coat and allele for this is c
If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:
P1: chinchilla x chinchilla
P1: Cch Cch X Cch Cch
F1: Cch Cch : Cch Cch
Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype it means that all the offspring will have chinchilla phenotype that makes option C correct.
Hope it help
Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.
Because it determines if it is isolated or not. This means if other substances can enter or not. This usually relies on the membrane with it´s pores. The pores help the membrane be selectively permeable in what it lets in and out.
