Question 1

what is a oragnic molocule?

Answer 1

An organic molecule is derived or produced from living things, they usually contain carbon atoms, usually connected to hydrogen atoms

Question 2

What is an inorganic molecule?

Answer 2

An inorganic molecule does not have any carbon and is derived from metals

Question 3

An example of an organic molecule?

Answer 3

lipids, proteins, carbs

Question 4

An example of an inorganic molecule?

Answer 4

Metals and minerals like iron, calcium, sodium

Question 5

What does our body use proteins for?

Answer 5

the building block for your body. made to build or repair muscles, bones, skin, everything

Question 6

What does our body use carbs for

Answer 6

Carbs are our body’s preferred energy source. it’s our body energy

Question 7

What does our body use lipids for

Answer 7

they store and absorb unused energy/nutrients for later

Question 8

What is a substrate

Answer 8

A substrate is the material in which an organism moves or lives

Question 9

What are some substrates that humans and other living things need to live?

Answer 9

fish need water to live, so water would be one, and mold can grow on organic matter like bread

Question 10

What does ph stand for

Answer 10

potential for hydrogen

Question 11

What does pH measure?

Answer 11

the number of hydrogen ions in a solution

Question 12

What is the formula for the pH scale

Answer 12

For every number on the pH scale, it can go up or down 10x in acidity. for example, sea water is 8 on the pH scale and water is 7 on the pH scale, so water is 10x more acidic

Question 13

What is the relationship to hydrogen ions and acidity

Answer 13

the more hydrogen ions something has the more acidic. for every number on the ph scale it goes 10x higher or lower then the one ahead or above. example: water has a ph of 7 and sea water has a ph of 8. so sea water has 10x less hydrogen ions then water.

Question 14

what is biomagnifcation

Answer 14

is the process of increased concentration of harmful substances (like mecury or pesticides) the higher on the food chain

Question 15

example of biomagnfication

Answer 15

a algae absorbs a tiny amount of mercury, then a small fish eats 10 alage giving the fish a small amount of mercury, then a big fish eats 10 small fish giving the big fish a medium amount of mercury. and then a shark eats 10 big fish giving the shark a huge amount of mercury

Question 16

who is affected mosy by biomagnifcation?

Answer 16

animals on the top of the food chain

Question 17

what is passive transport?

Answer 17

passive transport is when a plant does not need to use energy to transport somthing, this happens thorugh osmosis and diffusion

Question 18

what is osmosis

Answer 18

osmosis is the process of water moving through the plants roots from a area with a abudence of water molocules, to a area with fewer water molocules. water moves through a semi permable membrane

Question 19

what is diffsuion

Answer 19

the movment of molcules from a high concentration area to a low concetration area, it all evens out.

Question 20

what is active transportation?

Answer 20

when the plant has to use energy to move somthing. moving somnthing the oposite way of diffusion.

Question 21

give a example of active transportation

Answer 21

when a canoer goes against the river in order to transport nutrients. that is essintaly active transportaion.

Question 22

what is fertilizer used for?

Answer 22

to increase the nutrients concentraion in soil.

Question 23

what do the numbers mean on fertilizer bags?

Answer 23

it means the perchentage of nitrogen, phosphorous, and potassium in the bag.

Question 24

what are bioindicator species

Answer 24

biondicator spechies are species used to measure the health of a ecosytem. just the existenace of these species in a area can be a signal of good ecosytsem health.

Question 25

what are some dangers of fertlizers?

Answer 25

minerals that are used in fertlizers can runoff into lakes. leading to the heavy over growth of alage. some fertlizers contain heavy metals taht could prove harmful to the enviorment.

Question 26

what are some causes of air pollution

Answer 26

cars planes and ships releasing Co2, methane gas produced by agriculture, the burning of fossil fuels to produce certain goods.

Question 27

what are some solutions to air pollution

Answer 27

the use of renewable energy instead burning fossil fuels. walkable citys so cars arent as relided on. and better farm pratices like better animal waste management to lower the production of methane

Question 28

what is liming?

Answer 28

is the process of decreasing the acidity of a water or soil by adding bases (like limestone).

Question 29

what are some drawback of liming?

Answer 29

would have to constantly do it due to acid rain, and it is very costly

Question 30

how do you neutrlize a base or acid?

Answer 30

if you are neutrlizing a acid you need to add a base, vice versa for neutrulzing a base

Question 31

what is neutrlizing?

Answer 31

its a chemcial reaction between a acid and base, producing water and salt

Question 32

does neutrlizing always produce a neytral substance?

Answer 32

no someone has to use a acid or base of the same strength to fully neutrlize somthimg. but it can still decrease or increase the acidity of somthing if the strength dosent exaclty match

Question 33

what is ddt

Answer 33

a pesticide used in WWII to exterminate lice and mosquitos. the use of DDT lead to a drsatic decrease in the lice and mosquito population

Question 34

drawbacks of DTT

Answer 34

it takes a very long time to decompose, a whole 12 years. it is also fat soulble meaning it can be soaked up in the tissue of diffrent organisms

Question 35

examples of DTTS devestaion

Answer 35

it was sprayed at mosquitos and bugs in general, when fish ate these bugs they beagn having DDT inside their bodies, eagels eventually ate these fish also getting DDT into their bodies. Eagel eggs has thinner shells a s aresult

Question 36

how is acid rain produced?

Answer 36

when Sulfrates and NItrates prodcued by citys and factorys combine with moisture in the air, the result is a lower ph then normal rain.

Question 37

what are some affects of acid rain?

Answer 37

can cause entire lakes to be acidic/have a lower ph, erodes plant structre, erodes man made buildings

Question 38

what is Eutrophication?

Answer 38

when their is a overgrowth of Algae due to a build up of nutrients in water.

Question 39

how does Eutrophication happen?

Answer 39

when fertlizers, sewage, and livetsock manure seep into bodys of water, the mineral and nutrients build up leads to Eutrophication

Question 40

what is biodegrability

Answer 40

the ability of somthing to be able to be broken down by microorganisms.

Question 41

what are some chartesitcs of landfills?

Answer 41

-some landfills have a clay liner so the garbage juices dont seep into bodys of water -most of the garbage is covered in dirt so it dosent blow away and attract scavangers -organizing garbage into recycable and organic can help prevent the build up of garbage.

Question 42

What is LD50

Answer 42

the amount needed to kill 50% of the population, this is measured in ppm. the lower the number the more deadly
