Question 11

where does blood from the vena cava flow into the heart?

Answer 11

right atrium

Question 12

what is mitosis needed for in multi cellular organisms?

Answer 12

Cell division by mitosis is important in the growth and development of multicellular organisms

Question 13

how do bacteria cells reproduce?

Answer 13

Bacteria multiply by a type of simple cell division known as binary fission

Question 14

How often do bacteria cells multiply in ideal conditions?

Answer 14

In the right conditions, some species of bacteria (such as coli) can multiply as much as once every 20 minutes

Question 15

What is a stem cell?

Answer 15

A stem cell is an undifferentiated cell

Question 16

what is binary fission?

Answer 16

it is the mitosis of the bacteria

Question 17

what is diffusion?

Answer 17

substance or gas going from high too low concentration

Question 18

what is osmosis?

Answer 18

diffusion of water through either high too low or low too high via permeable membrain

Question 19

what is active transport?

Answer 19

Transports substances from a low concentration to a high concentration up the concentration gradient. this requires intervention ( plants or animals do this intentionally)

Question 20

how does the blood travel through the heart?

Answer 20

it comes from the lungs, it goes to the vena cava and enters right atrium and then the right ventricle and exits out the pulmonary artery and for the left it enters from the pulmonary vein and goes to the left atrium and then left ventricle then it exits out of the aorta the heart is swapped (Left is right and right is left)

Question 21

translocation

Answer 21

Phloem tissue transports dissolved sugars from the leaves to the rest of the plant for immediate use or storage​

Question 22

Transpiration​

Answer 22

Water travels up xylem from the roots into the leaves of the plant to replace the water that has been lost due to transpiration​. Lost through stemata.

Question 23

Virus

Answer 23

measles, HIV, Tobacco mosiac virus​

Question 24

Bacteria

Answer 24

salmonella, Gonorrhoea​

Question 25

Fungi

Answer 25

rose black spot

Question 26

Protist

Answer 26

malaria

Question 27

Phagocytes

Answer 27

Phagocytes engulf and digest pathogens, this can be non-specific or helped by antibodies which cause agglutination (clumping) of pathogens​

Question 28

Lymphocytes

Answer 28

Lymphocytes produce antibodies​. The aim of antibody production is to produce the antibody that is specific (complementary) to the antigens on the surface of the pathogen​

Question 29

Metabolism ​

Answer 29

Metabolism is the sum of all the reactions in a cell or the body – these reactions happen all of the time​ ​

Question 30

what is anaerobic respiration?

Answer 30

Glucose -> Lactic acid in cytoplasm

Question 31

what is aerobic respiration?

Answer 31

glucose + oxygen -> carbon dioxide + water

Question 32

what does Stents do?

Answer 32

A stent is a small medical device used to treat and prevent the narrowing or blockage of blood vessels by providing structural support to keep them open, thereby restoring or maintaining normal blood flow. structure is in the form of a tube

Question 33

pros and cons of stents?

Answer 33

pro: surgery is quick last long time con: surgery has risks blood cloting

Question 34

what does Statins do?

Answer 34

primarily lower levels of LDL (low-density lipoprotein) cholesterol in the bloodstream, reducing the risk of heart disease and related cardiovascular events.

Question 35

pros and cons of Statins?

Answer 35

pros: decreases bad cholesterol lowers chance of CHD and others cons: have to constantly take side effects
