Answer: All
Explanation: A community is an assembly of one or more species that interacts with one another. However, in a community, the organisms would also interact with their environment.
Answer:
The Na⁺/Ca²⁺ exchanger, which couples the movement of Na⁺ down its electrochemical gradient with the movement of Ca²⁺ against its electrochemical gradient, is a(n) <u>symporter secondary active transport </u>because Ca²⁺ and Na⁺ move in different directions across the membrane.
Explanation:
The Na⁺/Ca²⁺ exchanger is a secondary active transport because it uses the energy of the Na⁺ that moves in favor of its electrochemical gradient to bring a Ca²⁺ ion against its electrochemical gradient inside the cell. This transport needs the help of a symporter, which is a protein that moves two different ions in the same direction.
So, both pea plants being crossed are homozygous reds, which means that their alleles look like: RR. This means that there are only R alleles present, so you can't have any other kind of flower without a genetic mutuation.
This means that the offspring must have a red flower, which would occur 100% of the time.
It would be A, they both have different properties, as they say it, different functions.
The electromagnetic spectrum of visible light is shown in the figure below: From the figure, the red<span> color has the longest wavelength the </span>violet<span> color has the shortest wavelength</span>
