Answer:
aa
Explanation:
A widow's peak is the dominant genotype so one must not have that trait. If it was presented then the woman would have the genotype.
A widow's peak is dominant so the man would be either AA or Aa. Since it stated that his is heterozygous (Hetero meaning two different), his genotype would be Aa (again since a widow's peak is the dominant, it only needs one dominant genotype)
Mould growing on a tomato that is sitting on a countertop be used as evidence for the spontaneous generation theory.
<h3>What do you mean by spontaneous generation theory?</h3>
According to the hypothesis of spontaneous generation, the emergence of life things from nonliving materials was both common and predictable. It was proposed that some forms, like fleas, may develop from inanimate substances like dust or that maggots could develop from decomposing human flesh.
In addition to causing postharvest rot during harvest and storage, a gray mold of tomatoes can also spread a number of other diseases, such as damping off and blight. A fungus with a host range of over 200 plants causes gray mold on tomato plants. It will be evidence for spontaneous generation theory.

Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Answer:
Type II alveolar cells.
Explanation:
Type II alveolar cells produce and secrete pulmonary surfactant, a liquid with phospholipids that reduces the surface tension avoiding the collapsing of the alveoli walls and making possible the entrance off air to the alveolar sac in order to exchange O₂ for CO₂.
