Key Words (I did a bit but still needs more)

Question 1

Magnification

Answer 1

Magnification is the multiplier of the actual object to get the image. Eg “magnification of x10 with an object of 10cm makes an image of 100cm”

Question 2

IAM triangle

Answer 2

Image = actual( magnification)
Actual = image/magnification
Magnification = image/actual
Where actual is the actual size of the object

Question 3

Resolution

Answer 3

The smallest measurable distance of two points. (Eg. two points next to each other on a computer screen if close enough will appear as one pixel and not as separate entities)

Question 4

Nucleus

Answer 4

The nucleus is found in eukaryotic cells. It contains the majority of the cells genetic material. The material is organised as DNA molecules along with a variety of proteins to form chromosomes.

Question 5

What is the Cytoplasm?

Answer 5

It is the liquid in the cell where the contents of a cell are suspended and where most of the chemical reactions needed for life take place

Question 6

Cell membrane

Answer 6

The ‘wall’ surrounding the cell which maintains what comes in and out of the cell

Question 7

Mitochondria

Answer 7

The mitochondria is an organelle found in most types of cells. It is the site of respiration and is responsible for producing energy.

Question 8

Eukaryotic cells

Answer 8

• more complex organisms (multicellular)
• Have a true nucleus in the cytoplasm which encloses genetic material
• plants, animals and fungi include eukaryotic cells

Question 9

Plasmid

Answer 9

Add ensures

Question 10

Order of magnitude

Answer 10

To find the ‘order of magnitude’ divide the larger number by the smaller number and if the product is bigger than less than 10 then the order of magnitude is considered the same.
10 >= x is 10^1
100>= x is 10^2
(It’s a bit of a joke tbh)

Last word in dictionary.

Question 52

Carbohydrase

Answer 52

An enzyme.

Question 53

Lipase

Answer 53

Lipase is an enzyme that breaks down dietary fats into smaller molecules called fatty acids and glycerol. A small amount of lipase, called gastric lipase, is made by cells in your stomach. This enzyme specifically digests butter fat in your food. Breaks down fats (lipids).

Question 54

Protease

Answer 54

A protease (also called a peptidase or proteinase) is any enzyme that performs proteolysis. Proteases have evolved multiple times, and different classes of protease can perform the same reaction by completely different catalytic mechanisms. They break down protein.

Question 55

Active Site

Answer 55

Part of enzyme where the chemical reaction occurs. It denatures if the ph or temperature is too high or low.

Question 56

Denatured Enzyme

Answer 56

An enzyme that can no longer help in digesting as its active site is deformed and doesn't match the shape of the molecule it is digesting.

Question 57

Blood Plasma

Answer 57

Yellow liquid with suspended blood cells. It makes up 55% of the blood. Transport dissolved products. E.g. Co2, urea, insulin. Helps maintain constant body temperature.

Question 58

Red Blood Cells

Answer 58

Erythrocytes, are the most common type of blood cell.Don't have a nucleus.Biconcave shape. Small surface area to volume ratio. Contain the protein haemoglobin. They give blood its red colour. They carry oxygen to muscles. Make up 45% of the blood.

Question 59

Platelets

Answer 59

Platelets are blood cells critical to blood clotting, which is the process that stops bleeding.

Question 60

Veins

Answer 60

Carrying blood towards the heart where the pressure is not as high.

Question 61

White Blood Cells

Answer 61

leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.

Question 62

Arteries

Answer 62

Carrying blood away from heart where the blood is pushed at ha higher pressure.

Question 63

Capillaries

Answer 63

Very small blood tubes that are only 1 cell thick and carry the oxygenated blood to muscles and carry waste away from muscles.
