Question

Is there anyone on here that can help me with Environmental Science?

Answer 1

Hi Pamelaa - My BA is in that area so I might be able to help. What is your question?

Answer 2

I can give it a stab also

Answer 3

Thank yahl so much. Give me just a sec.

Answer 4

i have a study guide thats 150 questions & i need help with a few multiple choice & true & false, is yahl can please help?

Answer 5

True or False:
1. Famines are largely due to relative inefficiency of green plants to produce food.
2. Light is necessary in each step of photosynthesis.
3. The order in which amino acids are combined is not important.
4. All animal and human proteins originally came from the plant proteins.

Answer 6

2.) is false i'm 99% sure

Answer 7

1. False - famines can also be caused by misappropriation of resources
2. False - photosynthesis happens in the dark also
3. False - amino acids are building blocks of proteins and ordering is important
4. Trick Question - All proteins come from plants in the form of amino acids that animals eat...so in some sense, this is true

Answer 8

Thank you so much? Do you mine helping with more?

Answer 9

The light reaction takes place in the :
a: chlorophyll
b: mitochondria
c: cytoplasm
d: grana
e: stroma
ab: all the above
ac: none of the above

Answer 10

a

Answer 11

thank you

Answer 12

During the light reaction of photosynthesis which does NOT happen?
a: oxygen is produced
b: ATP is formed
c: glucose is formed
d: H is released

Answer 13

ATP isn't produced that happens during another stage which i can't remember the name of right now.

Answer 14

Which of the following is NOT true for proteins?
a: forms the protoplasm of all living things
b: composed of amino acids
c: is the fabric of life
d: each species has its own distinct protein
e: all the above are TRUE for proteins
ab: none of the above are true for proteins

Answer 15

You are really pushing the limit of my biology memory here but I think d, would be the incorrect answer here. Because hemoglobin is a protein and red blooded animals use that protien to transport O2 so thats what i'm going with.

Answer 16

Photosynthesis requires:
a: lights and chlorophyll
b: oxygen and water
c: light and oxygen
d: chlorophyll and sugar

Answer 17

Im sorry. But thank you so much for helping me with this!

Answer 18

ummmm...My best guess would be light and chlorophyll, I beleive sugar and oxygen is a bi-product of the light stage of Photosynthesis.

Answer 19

The basic process required for all life to exist is:
photosynthesis
meiosis
respiration
protein synthesis
glycolysis

Answer 20

Is that cell respiration as in the production of ATP? or respiration as in gas exhange occuring in the lungs?

Answer 21

Im not really sure. we can skip that one tho.

Answer 22

Consider the equation for photosynthesis, the oxygen that plants release comes from the oxygen in the:
water
carbon dioxide
both
neither

Answer 23

The oxygen that plants release comes from both co2 and water

Answer 24

Photosynthesis has how many steps?

Answer 25

That depends on how you look at it. There are two phases (light reaction and the Calvin Benson cycle), but those aren't exactly steps. The basic steps you here about most often are:
1 - Clorophyll traps the sunlight
2 - Plants get energy from the sunlight
3 - Roots retrieve nutrients and plant makes food
4 - Waste is discarded (oxygen produced)

But please don't count on that as your answer - it's much more complicated than that. Anyone else have suggestions here?

Answer 26

I'm a chemistry major with a year of basic biology, Atam's answer sounds good to me but I think it really depends on the course level this is for. I bet if you can catch someone in the bio help area they would be able to be much more helpful than me.

Answer 27

Ok, i will do that. thank you. (:

Answer 28

Sorry. Didnt mean to send that again.

Answer 29

Proteins are extremely complex _____ molecules
organic
inorganic

Answer 30

organic

Answer 31

During photosynthesis, which is NOT true?
a: the number of CO2 molecules used equals the number of O2 molecules released
b: CO2 reacts with water to produce a carbohydrate and O2
c: sunlight and chlorophyll are required
d: plants keep the carbon from carbon dioxide
e: oxygen is used up
ab: none of this is true about photosynthesis
ac: all of the above is true about photosynthesis

Answer 32

I'm going to say e is not true

Answer 33

I think this one is A but double check me please:
Water is _____ photosynthesis.
used in
produced by
both

Answer 34

you are correct

Answer 35

Which of the following statements is true for plants?
a: plants harvest the energy of the sun
b: on the cellular level, plants are extremely active
c: they are very efficient food producers
d: they produce oxygen
e: all is true
ab: none is true

Answer 36

Is that one E?

Answer 37

yea i would say that e is correct

Answer 38

Enzymes are specialized _________.
carbohydrates
proteins
fats
inorganic compounds
none of the above
