Answers
The inheritance pattern of pods color in pea plants is complete dominance. H0m0zyg0us dominant and heter0zyg0us plants have green pods. Option C) A, C, and D.
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
When you cross an individual who is h0m0zyg0us dominant with an individual who is h0m0zyg0us recessive, the whole progeny among the first generation -F1- will express the dominant phenotype since they are heter0zyg0us for this trait.
However, if you let individuals from the F1 cross with each other, the second generation -F2- will be composed of individuals expressing the dominant and the recessive phenotypes. This is because some individuals are h0m0zyg0us recessive and can express the recessive trait.
According to this information, and based on the attached flowchart, we can assume that,
Parentals ⇒ A (gray square) and B (white square)F1 ⇒ C (gray square)F2 ⇒ D (gray square) and E (white square)Since the F1 is completely gray, we can assume this color identifies the dominant phenotype (green pods).
The cross was performed between plants with yellow and green pods, so they must be h0m0zyg0us individuals (dominant and recessive) and the whole F1 must be heter0zyg0us for the trait. So,
A ⇒ h0m0zyg0us dominant because it is gray ⇒ green pods
B ⇒ h0m0zyg0us recessive because it is white ⇒ yellow pods
C ⇒ heter0zyg0us because it is gray and the product of A x B ⇒ green pods
Now, the F2 is composed of D and E which represent plants with yellow and green pods. This means that there are h0m0zyg0us recessive individuals, and the recessive trait -yellow pods- can be expressed again among the second generation.
D ⇒ h0m0zyg0us dominant and heter0zyg0us ⇒ green pods (gray square)
E ⇒ h0m0zyg0us recessive ⇒ yellow pods (white square)
Now, the phrase "Green pods" should appear i all gray squares. These are A, C, and D.
Option C is correct. A, C, and D only.

On an rna molecule, which would base pair with adenine?.
Answers
Uracil
Explanation:RNA stands for ribonucleic acid. This helps with the expression of genes.
Bases of RNA
RNA has 4 different bases: adenine (A), uracil (U), cytosine (C), and guanine (G). Next to each base, you can see the symbol that represents the base. These bases are called nitrogenous bases because they contain nitrogen and act as a base (as opposed to an acid). These monomers are one of the building blocks of nucleic acids.
In RNA, adenine and uracil bond, and cytosine and guanine bond.
DNA
RNA and DNA are commonly confused because they perform similar jobs, but nonetheless, they are different. One reason they are different is that DNA does not have uracil. In DNA, adenine bonds with thymine (T).

B. C₂H4O2 and H₂0 and chemical energy
C. H₂O and CO₂ and chemical energy
D. C₂H4O2 and H₂0 and sunlight energy
Answers
Answer: A
Explanation:
The three reactants used in photosynthesis are water (H2O) carbon dioxide (CO2), and light (sunlight energy). These reactants are used to produce glucose/food for plants and oxygen that is later released.
H₂0 and CO₂ and sunlight energy are reactants involved in photosynthesis. Therefore, option (A) is correct.
What do you mean by photosynthesis?Plants and other organisms use a process called photosynthesis to transform light energy into chemical energy that can later be released to power the organism's activities through cellular respiration.

What is the experimental group?
During an experiment the researcher compares at least two groups: a control group and an experimental group.
Both of them are composed of individuals coming from the same population, so they are identical in all aspects except for the independent variables.
The experimental group is the one that receives the treatment. The researcher voluntarily changes the values of the independent variable to observe how it affects the individuals subjected. There can be several experimental groups.
In the exposed example, the independent variable is eating saturated fat.
Among all the individuals involved in the experiment, the group that stops eating saturated fat is the experimental group.
