Question 2

osmosis

Answer 2

the diffusion of water through a semipermeable membrane

Question 3

passive transport

Answer 3

the movement of substances across a cell membrane without the use of energy by the cell

Question 4

active transport

Answer 4

the movement of substances across the cell membrane that requires the cell to use energy

Question 5

endocytosis

Answer 5

the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the partial into the cell

Question 6

exocytosis

Answer 6

the process in which a cell resales a particle by enclosing the participle in a vesicle that enclosing the particle in a vesicle that then moves t the cell surface and fuses with the cell membrane

Question 7

Answer 8

the process by which cells use oxygen to produce energy from food

Question 9

fermantion

Question 10

cell cycle

Answer 10

the life cycle of a cell

Question 11

chromosome

Answer 11

chromosome is made of protein and a single molecule of oligonucleotide acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Question 12

homologous chromosomes

Answer 12

Homologous chromosomes are similar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.
