Is asexual reproduction when the offspring is identical to one parent, an offspring that looks like a combination of both parents, or an offspring that looks like half of each parent?

it's when the offspring is identical to one parent

Explanation:

asexual reproduction only requires one parent, therefore being identical to it.

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.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
