Answer 2

Large amounts are found in the body eg Hydrogen, Carbon, Oxygen and Nitrogen

Question 3

Answer 3

Elements that are less common in the body but still exist

Question 4

Bonds

Answer 4

2 or more atoms stuck together forming a complex structure

Question 5

Covalent Bonds

Answer 5

Atoms share electrons to form electron pairs between atoms

Question 6

Ionic bonds

Answer 6

Formed between two or more atoms buy giving/taking electrons

Question 7

Ion (Cations)

Ion (anion)

Answer 8

Negatively charged atoms (gains electrons) eg Cl-

Question 9

Anabolic Chemical Reaction

Answer 9

Bonds are being formed between atoms

Question 11

Catabolic Chemical Reaction

Answer 11

Bonds are breaking between atoms

Question 12

Rearrangement Chemical reaction

Answer 12

No atoms are created or destroyed

Question 13

What influences chemical reaction rate?

Answer 13

Temperature, surface area, catalysts, speed

Question 14

What is the point of homeostasis ?

Answer 14

The maintenance of internal body conditions

Question 15

What is the set point in homeostasis ?

Answer 15

The range of values where they should be within for optimal performance

Question 16

What’s a stimulus

Answer 16

What can trigger a range in variables

Question 17

What are some things that need to be within a set point range ?

Answer 17

Heart rate, body temperature, glucose and blood pressure

Question 18

Negative feedback loop

Answer 18

The effector works to immediately restore the variable to its set point range

Question 19

Positive feedback loop

Answer 19

The effector works to push a variable further outside of its range this allows the body to facility some very specific actions before resetting the variable to its set point range

Question 20

Frontal Plane

Answer 20

Anterior and posterior

Question 21

Transverse Plane

Answer 21

Superior and inferior

Question 22

Sagittal/Lateral Plane

Answer 22

Left and right side

Matter referred to anything that

Answer 23

Occupies space and has a mass

Question 24

ATP

Answer 24

Energy that drives chemical activity

Question 25

Lipids

Answer 25

Water insoluble organic compounds that provide a main source of energy for body cells to make ATP

Question 26

What’s the control centres job in homeostasis

Answer 26

Compares the actual value of variable to its set point range of values

Question 27

What’s the effectors role in homeostasis

Answer 27

To initiate activities that change the variable and bring it back to its set point range
