Hi everyone, these are questions from bio 101 lab book. This book is written by one of our college professor which answers can’t be found from the book. So I need yall help desperately and quick as possible… you don’t have to answer all but please do ones you know for sure. I’ve guess couple of them, so please check my answer, and help me and tell me what the answers are for the others… thank you so much in advance.

d.I2KI
DON”T KNOW
7)an example of a heterotrophic organism is
a.a plant
b.a geranium
c.a human
d.none of the above
DON”T KNOW
8)organism capable of producing their own food are known as
a.autotrophs
b.heterotrophs
c.omnivored
d.herbivored
DON”T KNOW
9.grana are
a.the same as starch grains
b.the site of ATP production within chloroplasts
c.part of the outer chloroplast membrane
d.contained within mitochondria and nuclei
DON”T KNOW
10) the ultimate source of energy trapped during photosynthesisi is
a.CO2
b.H2O
c.O2
d.sunlight
MY GUESS IS D
Bio 101 lab questions... please i need help desperately and quick?
I would educationally guess CACCABCABD. Only two have been guesses, albeit educational ones but i'm pretty certain on most. Simple searches on google for key terms would have helped you.
Reply:Ok, these are the ones I know for sure: 1.c 2.a 3. the formula for photosynthesis is 6CO2 + 12H2O + sunlight ---%26gt; 6O 2 + C6 H12O 6 + 6H2O so all of those are components7.c (heterotroph is one that relies on something else for sustenance) 8.a 10. d light drives photosynthesis. The rest I don't know about.
Reply:1, is b, because glucose is the reactant in photosynthesis.
2. a
3. glucose, obviuosly it is what is used to start the reaction therefore u cant have it be the product also.
4. c
5, not sure, i looked it up but nothing came up.
6. starch, i just had that lab a few weeks ago
7. heterotrophic means organisms that have the ability of synthesize their cells by not just using carbon dioxide but other compound as well. but dont know which one of your option is the answer here.
8.a
9. ?
10. d the sunlight is the ultimate energy source for everything on earth.
Reply:1. C, this produces glucose.
2. Specroscope, you want to see the spectrum
3. I am thinking C, but photosynthesis does not give off water does it?
4.C, since it is paper, it can separate pigments.
5. B since both chlorophylls and cartenoid should be found.
6. I'd say benedict's solution, it t tests for sugars
7. D, I would say, they rely on their surroundings, meaning they get carbon from their surroundings
8. A: latin "self" "nutrition"
9.B, they are stacks of Thykaloids
10 D: without it, nothing would happen
