75% purp, 25% white i would think. you could easily eliminate the 50% purp 50% white because that wouldn’t make sense, purp is the dominate color. it would most likely not be 100% purple because there are two 25-75 answers, which would most likely make it one of those answers. since purp is the dominate color, 75% white would not make sense, making the correct answer 75% purp and 25% white.

A human cheek cell's cycle is 24 hours. The stages within the cell cycle vary in length. G1 phase - 11 hours, G2 phase - 4 hours

Answer:

answer is c

Explanation:

The cell needs a lot of preparation and checks in G1, S and G2 to do mitosis. especially in the G1 phase which is the longest phase. It is explained by the fact that the cell should "rest and recover" after the last mitosis before getting into the second one

PLEASE LOOK AT THIS!!!

Talja [164]

Answer:

Solid: State of matter with definite shape.

Gas: State of matter with particles very far apart.

1 or 3: Arrows that show particles getting closer together.

2 or 4: Arrows that show particles gaining energy.

Gas: State of matter that will fill any container.

Liquid: Sate of matter with definite volume but not shape.

Solid: State of mater with least amount of kinetic energy.

Explanation:

There are three states of matter :

Solid: It is the state in which atoms are tightly packed such that either they can make no movement at all or just can cause vibrations. Hence, solids have a definite shape and volume.

Liquids: When the solid molecules are heated, they gain energy and free themselves, converting into the liquid state. The molecules have a definite volume but not a definite shape.

Gas: When liquid molecules are heated together, they gain more energy and start hitting the walls of the container with a much greater space. They move more freely in this state and hence the molecules do not have a definite shape or volume in this state.
