Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
i think its either d or b! go with d first tho <3
I believe you meant 'selective breeding'.
Selecitve Breeding is when say a dog breeder, chooses two prospective parents in hopes of achieveing a superior offspring or offspring with desired traits.

Answer:
C. Fly Cap mushroom
Explanation:
All fungi are heterotrophic organisms because they obtain food and energy from external sources. Moreover, fungi are non-motile since they don't move. Finally, these organisms produce both sexual and asexual spores which are dispersed by wind and water.
On the other hand, the mushroom is the body of a fungus that grows on the soil, generally in humid and shady areas. The fly agaric mushroom is one of the most recognizable species of fungus.
