Answer 2

g1, S, and g2

Question 3

Stage of interphase where the cell replicates dna

Answer 3

S

Question 4

Cell division

Answer 4

Mitosis

Question 5

Stage where the dna forms chromatids, and the spindles appear

Answer 5

Prophase

Question 6

Stage where the chromosomes move to the middle of the cell

Answer 6

Metaphase

Question 7

Stage where the spindle fibers pull the chromosomes toward the poles

Answer 7

Anaphase

Question 8

Stage where the nuclear envelops reforms

Answer 8

Telophase

Question 9

Stage where the cytoplasm divides

Answer 9

Cytokinesis

Question 10

Diffusion rate is affected by

Answer 10

molecule size
Temp
Amount of energy

Question 11

No ATP is required for this transport

Answer 11

passive transport

Question 12

ATP is required for this transport

Answer 12

Active transport

Question 13

Where molecules pass through the plasma membrane

Answer 13

Diffusion

Question 14

Where water passes through the plasma membrane

Answer 14

Osmosis

Question 15

Normal concentration gradient is

Answer 15

High to low

Down

Question 16

Going against the concentration gradient is

Answer 16

Low to high

Question 17

This solution has same concentration as cells, no visible changes

Answer 17

Isotonic

Question 18

This solution has more solutes than the cell, shrink

Answer 18

Hypertonic

Question 19

This solution has less solutes than the cell, swells

Answer 19

Hypotonic

Question 20

Molecules can pass through the plasma membrane is helped by a carrier protein

Answer 20

Facilitated diffusion

Question 21

Solutes, like salt or glucose, diffuse across the plasma membrane from high to low concentrate. Passive. Only certain size can get through.

Answer 21

Dialysis

Question 22

Define the sodium-potassium pump

Answer 22

ATP energizes the pumping of sodium into the cell, and potassium out. Goes against concentration gradient.

Question 23

When water is put in a solute:

Answer 23

The lower concentration flows into the higher one.

Question 24

What is the transfer rate for the sodium potassium pump

Answer 24

3 sodium in and 2 potassium out
