The allele for a green shell (H) is dominant to the allele for a brown shell (h). The phenotype ratio of Generation 2 for Group R is shown in the diagram A Place a genotype into each blank box in Generation 1 for Group R to show what cross would produce the phenotype ratios shown in Generation 2
Place a beetle in each blank box in Generation 2 for Groups S and to show the expected phenotype ratios.
• Place only one genotype/beetle in each box
• You may use each genotype/beetle more than once.
• There may be more than one correct answer

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
