Passive transport has 3 concepts to it.. these include: diffusion, facilitated diffusion and osmosis. All 3 of these are when a solution goes from an area of high concentration to an area of low concentration. All three of these are how substances move in and out of cells. Active transport refers to a substance going from an area of low concentration to an area of high concentration. The three of these include: plasma membrane in relation to calcium and potassium, endocytosis, and extocytosis. The function of these three is to also bring substances from an area of high concentration to an area of low concentration. Membrane pumps do this by bringing the high concentration to inside the cell so the potassium and calcium switch spots. With endocytosis and extocytosis, endocytosis brings items into the cell by digesting (phagocytosis) and drinking them (pinocytosis); extocytosis almost pushes away the cell and that’s how it gets across the membrane
Answer:
B
Explanation:
take salt water for example if you put a egg without a shell in it the water leaves the egg because of the salt water's low concentration
the role of plants in carbon cycle
Explanation:
the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
The three biotic factors that can affect an organism after death are scavengers, predators, and decomposers that can breakdown and destroy the organism.
Answer:
See the answer below
Explanation:
a) Since the pink phenotype is heterozygous, the genotype would be RW.
b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:
RW x RW
RR RW RW WW
<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW
<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
