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.

Research cheetahs on the internet what has contributed to this animal becoming "endangered" or "threatened." what animal you have chosen? -cheetah how long has the animal been endangered or threatened? what has contributed to this animal’s endangered or threatened status? why is it important to save this animal from extinction? after researching and gathering facts, write a 350-word letter from the point of view of an animal rights' activist. be sure to include at least five facts that you learned from your research.

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
