what 4 jobs does the liver preform?

Answer 3

• fighting off infections
• breaks down lactic acid
• neutralises toxins and alchol
• controls blood sugar
• helps clot the blood

Question 4

What does a hepatic portal vein do?

Answer 4

carries blood containing digested food from the intestines to the liver

Question 5

What does the hepatic artery do?

Answer 5

brings oxygenated blood to the liver

Question 6

what is Abiotic?

Answer 6

• climate
• temperature

Question 7

What is biotic?

Answer 7

• plants
• foods
• predators and prey

Question 8

what do plants compete for?

Answer 8

• sunlight
• water and nutreints
• trees
• space/ tretirotry

Question 9

What do animals compete for?

Answer 9

• food
• water
• territory
• mates

Question 10

What are the benefits of the stomatta on the underside of the leaf

Answer 10

water dosent eveporate

Question 11

What are the benefits of rolled up leaves

Answer 11

reduces waterloss through evaporation

Question 12

What are the benefits of spine shaped leaves?

Answer 12

reduces waterloss as it reduces surface area

Question 13

What are the benefits of a thicker waxy cuticule?

Answer 13

• filled with chlorphyll which reduces water loss as there is less surface area, less sunlight reduces concentration gradient

Question 14

what is abundance?

Answer 14

how many living organisms there are

Question 15

what is distrubution?

Answer 15

how the organisms are spread out

Question 15

what is a food chain?

Answer 15

it shows the transfer the energy between organisms

• always start with producers

Question 16

what is a herbivore?

Answer 16

an animal that only eats plants

Question 17

what is a predator?

Answer 17

captures and eats other animals

Question 18

what is a prey?

Answer 18

any animal that serves as a food source for other animals

Question 19

what is a consumer?

Answer 19

organisms that feed on plants or other animals for energy

Question 20

what is a primary consumer?

Answer 20

a group of organisms that are placed in the second trophic level

Question 21

what is a producer?

Answer 21

can photosynthesise to produce glucose and is first in the food chain e.g algae and plants

Question 22

What are 3 things linked to the carbon cycle?

Answer 22

• combustion
• respire
• photosynthesis

Question 23

what is combustion?

Answer 23

the process of burning something at a high temperature

Question 24

what is photosynthesis?

Answer 24

the process plants use sunlight, water and carbon dioxide to create oxygen and energy in glucose the process by which plants and some other organisms convert light energy into chemical energy in the form of glucose

Question 25

what is respiration?

Answer 25

chemical reaction to release energy

Question 26

what is the equation for respiration?

Answer 26

oxygen + glucose --> carbon dioxide + water

Question 27

what is the equation for combustion?

Answer 27

oxygen + fuel --> carbon dioxide + water

Question 28

what are the stages of the water cycle?

Answer 28

- condenstion - precipitation - evaporation - transpiration

Question 29

describe the process of the water cycle

Answer 29

1. Evaporation: Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air. 2. Condensation: water vapor changes it's physical state from a vapor to a liquid. Water vapor condenses onto small airborne particles to form fog or clouds. 3. Precipitation: The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow 4. Collection: The fallen precipitation is then “collected” in bodies of water such as rivers, lakes and oceans – from where it will eventually evaporate back into the air, beginning the cycle all over again
