Question

I need help with Advanced Academics assignment. who could help?

Answer 1

sure....???

Answer 2

okay cool.
Mitochondria produce energy for the cell by ___________.
A. combining carbon dioxide, water, and sunlight
B. reacting oxygen with glucose
C. splitting hydrogen atoms
D. using chlorophyll to capture sunlight

Answer 3

@melissaholmes

Answer 4

okay... so....

Answer 5

you know what mitochondria are... right?

Answer 6

yes, power hosue right?

Answer 7

yeah!

Answer 8

so they are the powerhouses of the cell... meaning they make all the energy.
to make this energy, there has to be a chemical reaction. we eat food, and the mitochondria takes the food, and breaks it down into glucose molecules, then uses these molecules to make energy... so what do u think?

Answer 9

i dont want to sound dumb. so mabe... B. reacting oxygen with glucose...?
i have no clue.

Answer 10

we breathe the air in for oxygen, and eat food for the glucose... and the mitochondria takes these and breaks it down to form molecules... so yeah, B! :D

Answer 11

okay cool. ready for the next? ;P

Answer 12

It's B!!

Answer 13

sure!

Answer 14

lol

Answer 15

:D

Answer 16

When we say the cell membrane is selectively permeable, we mean that
A. the cell is bathed in liquid.
B. oxygen and water cannot enter the cell.
C. some substances can pass through the membrane.
D. it has a high concentration of salt.

Answer 17

u know what the cell membrane is?

Answer 18

yeah i think its c...?

Answer 19

yeah, u r correct! the cell membrane is "selectively" permeable, meaning some things can come in some things can't... this is because the cells in your body need certin nutrients, but want to keep others out. :D

Answer 20

okay! thanks, next?

Answer 21

yeah, why not?

Answer 22

Which of the following correctly compares diffusion, osmosis, endocytosis, and exocytosis?
A. Diffusion and endocytosis are examples of passive transport. Exocytosis and osmosis are examples of active transport.
B. Diffusion and exocytosis are examples of passive transport. Endocytosis and osmosis are examples of active transport.
C. Diffusion and osmosis are examples of passive transport. Endocytosis and exocytosis are examples of active transport.
D. Exocytosis and endocytosis are examples of passive transport. Diffusion and osmosis are examples of active transport.

Answer 23

i'm guessing u don't know what any of these are?

Answer 24

well... i did at one point. i habe bad memory..

Answer 25

lol :D
exo - out: so transport out of the cell
endo - in: so transport into the cell
osmosis - only works for water; the membrane has certain protiens that let water in and out
diffusion sends stuff out of the cell by force

so:
exocytosis - passive transport
endocytosis - passive transport
diffusion and osmosis - active transport

Answer 26

so.. d.?

Answer 27

yeah! :D

Answer 28

u r better than most people i help.... they don't even read what i say... lol :D

Answer 29

hahah well, when i ask for help. i mean it, hahah.

Answer 30

that's good :D

Answer 31

ready for another? :P

Answer 32

yep... :D

Answer 33

hahah coool.

The organelle where cellular respiration occurs is the

A. mitochondrion.
B. cell membrane.
C. lysosome.
D. vacuole.

Answer 34

cellular respiration is the cycle that creates the energy for the cell...
so which organelle did we say is the powerhouse of the cell?

Answer 35

A. Mitochondrion...?

Answer 36

yeah!

Answer 37

awsome!

Answer 38

btw... what is advanced academics?

Answer 39

its like a thing to catch up in school. i transferred schools and we didn't have "biology" so now i have to take the course on the computer.

Answer 40

ok... cool. :D my parents made me do florida virtual school online to get ahead.... :)

Answer 41

ncie. was it easy?

Answer 42

it was ok.... i had to do a good amount of work, but at least i understood what i was doing... :)

Containers of water illustration

A. The water concentration will decrease in A, and water molecules will move from A to B.
B. The water concentration will decrease in A, and water molecules will move from B to A.
C. The water concentration will increase in A, and water molecules will move from A to B.
D. The water concentration will increase in A, and water molecules will move from B to A.

Answer 48

nah you prob cant.. u need the image..
