A population of squirrels living in a habitat covering 150 hectares is at 80% of the carrying capacity of 1,500. Assuming that the squirrels have a uniform distribution, what is the population density of the squirrels?

the calvin cycle has three stages. in stage 1, the enzyme rubisco incorporates carbon dioxide into an organic molecule. in stage 2, the organic molecule is reduced. in stage 3, rubp, the molecule that starts the cycle, is regenerated so that the cycle can continue

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

the actual answer was 160934

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
