Question 14

What is the cell membrane do?

Answer 14

Semi-permeable, maintains equilibrium in the cell. Composed of a phospholipid bilayer.

Question 15

What part of the cell membrane is hydrophilic

Answer 15

The phosphate balls, ‘the polar ends of the phospholipid molecules’

Answer 19

Literally everywhere.

Question 20

What is the cell membrane useful for?

Answer 20

To transport gases, nutrients and wastes in and out the cell. ALL SUBSTANCES MOVING IN AND OUT ARE CONSIDERED PARTICLES

Question 21

Mosaic meaning

Answer 21

Collection of different substances held together by a common material

Question 22

PARTICLE THEORY OF MATTER #1

Answer 22

All matter is made of particles; can vary in size and composition due to the substance

Question 23

PARTICLE THEORY OF MATTER #2

Answer 23

The particles of matter are constantly moving; move least in solids, most in gases. Adding energy (heat) can affect movement.

Question 24

PARTICLE THEORY OF MATTER #3

Answer 24

The particles of matter are attracted to one another or are bonded together

Question 25

PARTICLE THEORY OF MATTER #4

Answer 25

Particles always have spaces in them, smallest in solids, greatest in gases. Spaces can be occupied by the particles of other substances. (Ice is an exception, water has a lattice type of structure when frozen)
