Answer:
It must be large particles move into cells, unless there is another option
Explanation:
Passive transport does not require energy, so the first one is incorrect
Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect
So it should be large particles can move into cells, unless of course there is another option
Answer
Gametes that fertilize an ovum are called the sperms
Explanation
The reproductive cells of an organism are called the gametes or sex cells. Female sex cells are the ova/egg where as male sex cells are the sperms. The sperms are stored in the scrotum after their production in the male testes where as the eggs for females mature in female ovaries. During fertilization, sex cells meet in the Fallopian tube.
Answer:
1) b) hypotonic
2) a) hypertonic
3) a) water
4) a) B to A
5) c) osmosis
Explanation:
We have two compartments with water (A) and a solution in which the solvent is water and the solute is starch (B). The solutions are separated by a semipermeable membrane, which means that only the water molecules pass through the membrane.
1) In comparison with B, compartment A has a lesser amount of solute so it is hypotonic.
2) In comparison with A, compartment B has more solute (starch) so it is hypertonic.
3) The solvent is water, which dissolves the solute (starch).
4) Only the water molecules will pass through the membrane, and the molecules always move from the compartment with a higher concentration of solute (B) to the compartment with a lesser concentration of solute (A). So, the water moves from B to A.
5) The process in which the molecules of solvent move from a more concentrated solution to a less concentrated solution through a semi-permeable membrane is called osmosis.
