For points and brainliest.

1.

which involves transport proteins?

passive transport

osmosis

diffusion

active transport

2.

which describes a selectively permeable membrane?

allows only certain substances to pass through

allows large quantities of every substance to pass through

permits only certain substances to leave but all to enter

permits all substances to pass through in small quantities

3.

which describes starches and sugars?

proteins

enzymes

lipids

carbohydrates

4.use the diagram to answer the question.

what would occur if some of the red blood cells were placed in beaker c? recall that red blood cells normally float in plasma.

the concentration of water inside the cells would be less than outside, so the cells would swell.

the concentration of water inside the cells would be greater than outside, so the cells would shrink.

the concentration of water inside and outside the cells would be equal, so no osmosis would occur.

the concentration of water inside and outside the cells would be equal, so no diffusion would occur.

5.

which describes dna and rna?

carbohydrates

nucleic acids

proteins

lipids

6.

which term refers to the movement of molecules from an area of higher concentration to an area of lower concentration?

concentration

diffusion

collision

active transport

7.

active transport requires a cell to use

diffusion

collisions

its own energy

osmosis

8.

which describes a method of active transport?

cells rely on external energy to move molecules.

proteins carry molecules into or out of the cell.

molecules move into or out of a cell due to concentration.

water moves through the cell membrane by osmosis.

9.

what is a function of water in a cell?

the cell move and grow

producing lipids and carbohydrates

preventing rapid temperature changes

assisting in the production of proteins

10.

which describes engulfing?

active transport in which the cell membrane forms a new vacuole

passive transport in which the cell membrane surrounds a particle

active transport in which proteins move molecules in and out of the cell

passive transport in which water moves through the cell membrane

11.

why is water important for a cell?

water is the main ingredient in dna.

all proteins are made of water.

water is an essential organic compound.

most chemical reactions in cells require water.

12.

which is involved in engulfing?

golgi bodies

cell membrane

transport proteins

endoplasmic reticulum

13.

sugar molecules can combine with one another to form large molecules called

proteins

enzymes

lipids

starches

14.

the diffusion of molecules through a selectively permeable membrane is called osmosis.

water

oxygen

protein

carbon dioxide

15.

use the diagram to answer the question.

what would happen if some of the red blood cells were placed in beaker a?

water would move into the cells by diffusion, and the cells would swell.

water would move out of the cells by diffusion, and the cells would shrink.

water would move out of the cells by osmosis, and the cells would shrink.

water would move into the cells by osmosis, and the cells would swell.

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
