so for the 2nd question: an herbivore that eats only narrow leaves (organism with bb genotypes) will decrease f(b) and increase f(B)

And for the 1st question:

you have to calculate the allele frequencies for each generation and u can do that by writing 2 equations. After u find the values of f(b) and f(B) for each generation by comparing the values you can tell wether or not this population is in equilibrium. If the values have stayed fairly the same that means it’s in equilibrium and it is not evolving. I think this population is not in equilibrium and thus is evolving by looking at the numbers in the table.

If you still have questions or problems with the calculations leave a comment and I’ll help. :))

I need help ASAP!!! ECOLOGY

Based on value of change in shoot biomass, the study reveals that late plants benefited most from the introduction of soil invertebrates whole the early plants were worst affected.

<h3>What is ecology?</h3>

Ecology is the study of living organisms and their interactions with one another and their non-living environment.

From the observation of the study conducted:

A negative value of change in shoot biomass indicates that growth of each plant was reduced as a result of either competition for space or food.
The late plants were most positively affected as indicated by the highest positive value of change in shoot biomass whereas the early plants were most negatively affected as indicated by the lowest negative value of change in shoot biomass.

Therefore, it can be concluded from the study that late plants benefited most from the introduction of soil invertebrates whole the early plants were worst affected.

For the first 2 rows it’s going to be the dominant phenotype. So “purple flowers” for the 1st and 2nd row and white flowers for the last one. For the first row on #17 it’s going to be “FF “and “ff” for the 2nd. Tongue roller is “TT” and non tongue roller is “tt.”

What does a population pyramid represents?

scoray [572]

Answer:

B: a population’s age-sex structure

Explanation:

A population pyramid is a way to visualize two variables: age and sex.

They are used by demographers, who study populations. A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population. Expansive pyramids mean that the population does not increase much in total number and has many young people.

Hope this helps! Info from National Geographic, I would trust it if I were you!
