Question 12

Why does ice float on water?

Answer 12

Ice is less dense than water

Question 13

Adhesion

Answer 13

Molecules sticking to other things (By hydro bonds)

Question 14

Cohesion

Answer 14

Molecules sticking to themselves (By hydro bonds)

Question 15

Why doesn’t water and oil mix?

Answer 15

Water is polar, oil is non-polar

Question 16

Characteristics of life (Hint there’s 8)

Answer 16

Cells
Reproduce
DNA
Growth
Homeostasis
Evolve
Energy
Respond

Question 17

Tell me about the characteristics of life

Answer 17

All living things are made of cells
Reproduce to make more organisms
Grow to get bigger and change
Homeostasis to keep a constant environment
Evolve as a species to change the environment
Energy for metabolizing
Respond to cause a change in next response

Question 18

Otters maintain body heat by trapping air pockets in their fur which insulates. Harbor seals retain their heat with a layer of fat which also insulates. Why might a sea otter be less likely to be in homeostasis than a hardor seal in an oil spill?

Answer 18

The oil causes air pockets to open by bothering the hydro bonds. They won’t be able to hold in heat.

Question 19

9) Why are these gases able to move in the direction shown in the diagram

Answer 19

It diffuses because molecules go from high to low concentration.

Question 20

10) What is this process called?

Answer 20

Endocytosis - needs energy

Question 21

What do you think will happen if water had a lower specific heat?

Answer 21

Temperatures would change quickly so the earth wouldn’t stay warm in the cold.

Question 22

Why does diffusion happen?

Answer 22

Atoms are constantly moving and crashing into each other causing them to spread out.

Question 23

What is osmosis and what causes it to happen?

Answer 23

The diffusion of water causes it to go from high to low concentration

Question 24

14) What is going on?

Answer 24

Active transport

Question 25

Polarity in water, why is it that way?

Answer 25

Unequal distribution of electrons in water makes the oxygen neg. H is pos which causes attractions in hydro bonds.

Question 26

34) Based on this info, what will happen?

Answer 26

The protein will change because the amino acid has changed

Question 27

A cell with 24 chromosomes undergoes mitosis twice, how many chromosomes will each daughter cell have?

Answer 27

2

Question 28

What is the result of a fertilized egg?

Answer 28

Restores the diploid number

Question 29

Advantages of asexual

Answer 29

Less energy in the nuclei, it's faster, don't need a mate.

Question 30

38)

Answer 30

B D A C

Question 31

25) whats going on?

Answer 31

Meiosis

Question 32

26) What's the order?

Answer 32

``` Anaphase Interphase Metaphase Prophase Telophase Remember: A I M P T aimpit ```

Question 33

27)

Answer 33

Mitosis

Question 34

Diploid Me or Mi?

Answer 34

Mitosis

Question 35

Simple to Difficult in cellular organization

Answer 35

Cell - Tissue - organ - organ system - organism

Question 36

30)

Answer 36

Gene

Question 37

31)

Answer 37

Meiosis

Question 38

32)

Answer 38

Crossing over

Question 39

33)

Answer 39

If the DNA is Messed up, you lose proteins.

Question 40

(18

Answer 40

The tails are fatty acids and hydrophobic

Question 41

19)

Answer 41

``` Carbon Hydrogen Oxygen Nitrogen CHONP P is missing, These are ammion acids so the student is wrong. ```

Question 42

Draw: Interpahse (G1, S, G2) Mitosis, (PMAT) & cytokinesis.

Answer 42

20) check

Question 43

Compare MI and ME

Answer 43

Both start diploid, have cytokinesis, and do division. MI: Ends with 2 cells, Identical, Makes body cells. ME: Ends with 4 cells, different, makes gametes

Question 44

Skin cells divide by how?

Answer 44

Mitosis

Question 45

How many cells are made by the end of MI

Answer 45

2

Question 46

Crossing over happens during... | And what happens in this process?

Answer 46

Prophase 1 of meiosis | Homo chromosomes exchange genetic info.
