I believe the answer is C) How does a change in temperature affect the reproduction of crayfish?
The concentration of H+ ion (pH) could influence the structure of protein, which might inactivate some enzyme of an organism and alter their metabolism. All research questions beside option C is related to the pH. Buffer solution will provide an protection that will makes the pH become more stable. Acid rain contains acid which will decrease the pH of the surrounding environment.
Answer:
Due to its thin width and elasticity.
Explanation:
A jumping rope could be used to model the cell membrane of a plant cell because of their elasticity that acts like cell wall or cell membrane of the cell. Just like a cell wall or cell membrane which is the outer covering is thin in width and has the ability to elasticity so the jumping rope is also used in the model due to its elasticity and thin width so that's why we can used it in the cell model.
It's a fundamental law of how the universe organized.
Answer:
given,
rose combed rooster (R) × single combed hen (r)
RR × rr
↓
in F1 generation, all the chicks will be Rr
↓
in F2 generation, mating was done among their own group of Rr
Rr × Rr
↓
25% of RR 50% of Rr and 25% of rr
phenotypes of chicks in f2 generation = 3:1 ( 75% rose combed as R is dominant and 25% single combed)
genotype = 1:2:1 ( 1/4 homozygous rose comb [RR] : 2/4 heterozygous rose comb [Rr] :1/4 homozygous single comb [rr])
Photosynthesis is responsible for removing most CO2 from the atmosphere
