Multi-cellular Heterotrophs
Animals have more than one cell and can't produce their own food
Answer:
the last one which I'm guessing is d......cause it kinda messed up
The complete question is as follows:
1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
Answer:
1 . Surface area to volume ratio = 3 : 1
surface area= 3 cm³ or (l = 1 cm) (1 cm x 1 cm x 3) (W = 3)
volume= 1 cm³ (1cm x 1cm x 1cm)
2. Surface area to volume ratio = 6 : 1
surface area= 6 cm³ or (1 cm x 1 cm x 6 ) (w= 6)
volume= 1 cm³
Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm
Answer:
Position 2
Explanation:
Since it is on the Tropic of Capricorn, for it to be exactly on top of Africa, it must be in position 2. The Tropic of Capricorn is special because the sun is directly on top of it when the south part of the Earth is facing the sun, like position 2. Position 1 and 3 are directly at the Equator because neither part is tilted towards or away from the sun. Position 4 is directly above Tropic of Cancer. The Tropic of Cancer, like the Tropic of Capricorn, has the sun directly on top of it when the north part of the Earth is tilted towards the Sun.
I hope this helps!!! :)
Answer:
The present value after 2 years is $98
Explanation:
Given
Required
Determine the new value
This is calculated using:
Where b =
This gives:
So:
<em>The present value after 2 years is $98</em>
