A person being underweight

54
Q

What will too much food lead to

Is it true that the greater the persons mass the more energy they need

A

Yes

57
Q

Is it false that people who are active need more energy than people that are not

A

No

58
Q

Is it false that when adults get older then need less energy

A

No

59
Q

What percentage does protein make up of the body

A

18%

60
Q

What is diffusion

A

When particals move from an area of higher concentration to an area of lower concentration

61
Q

Parts of the breathing system

A

Diaphragm
Trachea
Alveoli
Lungs
Bronchioles
Nose
Bronchus
Rib cage
Mouth
Larynx
Intercostal muscles

62
Q

When we inhale:

A

Diaphragm contracts
External intercostal muscles contract
Chest cavity volume increases
Pressure in the lungs decreases
Air flows from high to low pressure
Air moves into the lungs

63
Q

When we exhale:

A

Diaphragm relaxes
Internal intercostal muscles contract
Chest cavity volume decreases
Pressure inside the lungs increases
Air moves from height to low pressure
Air moves out of lungs

What is vaping and what does it do

A

-Inhaling vapour produced by an e-cigarette
-e-cigarettes are a battery powered device. They have cartridges full of liquid inside them
-when the liquid is heated it creates a vapour

A

Ethanol and CO2

77
Q

Fermentation is

A

The process of glucose producing ethanol and CO2

78
Q
