Facilitated diffusion is the process by which molecules move across the plasma membrane with the aid of membrane proteins like channels and carriers. These molecules move down a concentration gradient, which gives them the potential to diffuse into (or out of) the cell.
Passive transport is a subset of facilitated diffusion. Because the solution is travelling down the concentration gradient, assisted diffusion is still passive transport even when it incorporates transport proteins. The cell membrane can easily be traversed by small, nonpolar substances.image outcome.A case of enhanced diffusion is glucose transfer. The lipid bilayer of the membrane prevents glucose from passing through since it is a big, polar molecule. In order to pass through, it requires carriers known as glucose transporters.

Explanation:
I think it's (A) The continents share a similar climate
Firewood,boiling water, and non living things are Abiotic(not alive) but grass because it is living it is Biotic.(alive)
Explanation:
When analyzing two linked genes there are 2 possibilities: either there is recombination between them during meiosis or there is no recombination. Crossing over happens during meiosis I, when each chromosome has two sister chromatids.
If no recombination happens, the 4 resulting gametes will be parental.
If recombination happens, 2 gametes will be parental and 2 gametes will be recombinant. For that reason, the maximum recombination frequency between two genes that can be calculated is 50% (recombination frequency = recombinants/total).
The correct answer is option A, They will have a large amount of genetic variation
Reason -
The transfer of pollens from the flower of one plant to the flower of another plant, is termed as cross pollination.
During cross pollination, two major instances can occur –
a) The transferred pollens may be of wild nature due to which fertilization of eggs do not take place
.
b) The transferred pollens can fuse with the egg of the parent plant and results into offspring’s that shall carry the characteristics of both the genetically distinct plants thereby producing hybrid plants.
