By definition: Facilitated diffusion<span> is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins.~Google
An example, the only I can really think of:
Polar and large molecules normally can't cross the lipid bi layer using simple diffusion, it usually has to be </span>Facilitated diffusion
Answer:
Krebs cycle
Explanation:
The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
Answer:
0.25
Explanation:
The population of panthers consists of 60 black panthers with the dominanat allele PP. 30 are pink panthers with the genotype Pp and 10 panthers are white with the phenotype pp.
The frequency of p allele in the population can be determined by
the number of individual with pp genotype + 1/2the number of individual with Pp genotype divided by the total number of individual.
Frequency = 10+1/2*30/100
Frequency = 0.25.
Thus, the frequency of p genotype is 0.25.
Gas exchange is the delivery of oxygen from the lungs to the blood stream, and gets rid of carbon dioxide from the blood. It occurs in the lungs between the alveoli and a group of capillaries.
