Re: Ecology B/C
Any idea what some prominent grassland invasive species are?

Re: Ecology B/C
Just wondering, will I need to go super in-depth with all the nutrient cycles (oxygen, carbon, sulfur, rock, water, phosphorus, nitrogen)? I do understand it and have notes on it but is it something that is frequently on the test?

How do you solve this: In a population of 100 jays, 35 individuals exhibit the recessive phenotype of brown feathers (bb) and 65 individuals exhibit the dominant phenotype of blue feathers (BB and Bb). What is the frequency of the allele for blue feathers?
I think this requires the Hardy-Weinberg equation, but I do not know how to use it in this case.
i wish i was good

Re: Ecology B/C
Let q be the frequency of the allele for brown feathers. Assuming only two alleles, q^2 is 0.35 by the Hardy-Weinberg equation, and 1-q is given to be the frequency of the allele for blue feathers, so the answer is 1- sqrt(0.35).photolithoautotroph wrote:Nutrient cycles do show up on almost all of the tests I have taken.NovaXY1 wrote:Just wondering, will I need to go super in-depth with all the nutrient cycles (oxygen, carbon, sulfur, rock, water, phosphorus, nitrogen)?

Re: Ecology B/C
I wouldn't imagine the rock cycle to be within the scope of the ecology rules, maybe some things about soils but not rocks I think.NovaXY1 wrote:I know I've already asked about this but will I need to learn the rock cycle? I feel like that would be needed for something like Dynamic Planet or Rocks/Minerals and not Ecology.

Re: Ecology B/C
Adding the rock cycle is in the manual for Rocks and Minerals specifically, I don't think you would need to add it in a biology event. (Even though some events do overlap, those are usually in the same branch of science.)NovaXY1 wrote:I know I've already asked about this but will I need to learn the rock cycle?
