FINALS 2

Question 1

What is photosynthesis?

Answer 1

Photosynthesis is the process in which plants take the energy from the sun’s rays and converts it into chemical energy.

Question 2

What is carbon dioxide?

Answer 2

Carbon dioxide, also known as CO 2, is the process in which carbon and oxygen bond together, which traps greenhouse gas and is changing the climate of the Earth.

Question 3

What is light energy?

Answer 3

Light energy is the only form of light that we can see. It can be converted into other types of energy, such as heat energy.

Question 4

What is glucose?

Answer 4

Glucose, also known as blood sugar, is a source of energy for plants and animals. It is also a carbohydrate.

Question 5

What are chloroplasts?

Answer 5

Chloroplasts are food producers of cells. They are commonly found in plants or bacteria, such as algae.

Question 6

What is chlorophyll?

Answer 6

Chlorophyll is a green pigment found in plants. It is used for plants to help it make food, and is used as medication for humans, helping to treat pancreatic, for example.

Question 7

What are the symbiotic relationship?

Answer 7

There are three types of symbiotic relationships:

MUTUALISM - when both organisms benefit

PARASITISM - one organism benefits at the expense of another

COMMENSALISM - one organism benefits, while the other is neither helped nor harmed

Question 8

What is an environment?

Answer 8

An environment is the surroundings in which an organism lives, including living and non-living things that can help or do damage to that environment.

Question 9

What is global warming?

Answer 9

Global warming is the gradual heating of the Earth’s oceans, surface, and atmosphere. This is caused by CO 2 trapping greenhouse gas.

Question 10

What is a habitat?

Answer 10

A habitat is an area in which an organism lives.

Question 11

What is instinct?

Answer 11

Instinct is something you do naturally, without having to learn it or think about it.

Question 12

What is migration?

Answer 12

Migration is an organism moving from one place to the next.

Question 13

What is an organism?

Answer 13

An organism is a plant, animal, fungus, bacterium, or protest.

Question 14

What does it mean to pollute?

Answer 14

To pollute something means to introduce something harmful to an environment.

Question 15

What is a stimulus?

Answer 15

A stimulus is something that cases an organism to react to something.

Question 16

What is a response?

Answer 16

A response a reaction to a stimulus.

Question 17

What is internal?

Answer 17

Internal is inside.

Question 18

What is external?

Answer 18

External is outside.

Question 19

What is the process of photosynthesis?

Answer 19

The process of photosynthesis:

1. the sun’s rays are directed towards a plant
2. the plant absorbs the energy from the sun and converts it into chemical energy

This process occurs in plants and algae. It happens because the plant is trying to get energy.

Question 20

What is internal stimuli?

Answer 20

Internal stimuli is a reaction to something inside the organism’s body, for humans, for example, internal stimuli would be having a virus, or eating food poisoning.

Question 21

What is external stimuli?

Answer 21

External stimuli is a reaction on the outside of the organism’s body. For example, with humans (again), when we are cold, we shiver, and when we are hot, we sweat.

Question 22

What are abiotic factors?

Answer 22

Some abiotic factors in an organism’s environment are things that are not living, such as rocks.

Question 23

What are biotic factors?

Answer 23

Some biotic factors in an organism’s environment are things that are living, like trees and grass.

Question 24

What is a food chain?

Answer 24

A food chain shows what nutrients and energy animals get from the food they eat. For example, a bunny eats grass, and the fox eats the bunny, while the fox is getting nutrients from both the bunny and plant.

Question 25

What is a consumer?

Answer 25

A consumer, also known as a heterotroph is an organism that gets energy from the carbon bonds that producers make.

Question 26

What is a producer?

Answer 26

A producer is an organism converts energy from the environment into carbon bonds, which consumers can get energy from.

Question 27

What are the waves on the electromagnetic spectrum?

Answer 27

The waves on the electromagnetic spectrum are radio waves, microwaves, infrared waves, light waves, ultraviolet waves, x-rays, and gamma rays.

Question 28

What are the parts of a wave?

Answer 28

FREQUENCY: The frequency is how many waves pass a certain point in a certain amount of time

WAVELENGTH: The distance between two peaks/troughs

PEAK: The top of the wave

TROUGH: The bottom of the wave

AMPLITUDE: The distance between the peak/trough of a wave and the equilibrium line

Question 29

What is reflection?

Answer 29

Reflection is when light or sound reflects off objects.

Question 30

What is refraction?

Answer 30

Refraction is the bending of a wave

Question 31

How do waves travel?

Answer 31

Waves travel through mediums with vibration, for example

Question 32

What can sound waves travel through?

Answer 32

Sound waves can travel through solids, liquids, and gases, but best travels through solids.

Question 33

How does the medium that a wave travels through affect the wave?

Answer 33

It can affect the wave by the boundary behavior. Boundary behavior is when a wave is traveling through a medium, it can either pass into another medium. When the wave passes into another medium, it does not affect the frequency.
