B- black allele;
b- brown allele;
The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb
The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being brown homozygote- bb- 25%
answer: 25%+25%=50% are homozygotes
Pot A that contained no fertilizer or compost will serve as a control in this experiment.
<h3>What is Fertilizer?</h3>
Fertilizer may be defined as any chemical or natural substance which is added to the soil with the intention to enhance the soil productivity.
Pot B contained fertilizer, while pot C contained compost, they will definitely grow more than pot A, but pot A serve as a control for this experiment because it does not contain any added resources into it. Hence, it grows naturally.
Thus, it is well described above.

Antibiotics are usually what can help. Depends what kind of infection you get and how severe it is.
Answer: b. one atom transfers an electron to another atom
Explanation:
An ionic bond is also called as the electrovalent bond. It is a type of linkage that is formed by the electrostatic attraction formed between ions of opposite charge in a chemical compound.
These bonds are formed when the valence electrons from one of the atom are transferred to the another atom.
