If the side of a cubical cell doubled, what would the cell then require? Select all the correct answers.
A. eight times more nutrients
B. to excrete eight times more waste
C. four times more nutrients
D. to excrete four times more waste
Given what we know, we can confirm that a cell that doubles in size would then require four times more nutrients, option C is correct.
Why would the cell require more nutrients?This has to do with the ratio between surface area and volume. Since volume is squared when calculating it, the volume of a cell increases much more rapidly than that of its surface area. So a cell that doubles in size would quadruple in volume, needed four times as many nutrients to maintain its internal processes.
Therefore, we can confirm that a cell that doubles in size would then require four times more nutrients, option C is correct.

I have many questions for my hw
Here are all the facts:
A girl, lets call her Grace, is wondering which pet she should get. she has owned a betta fish before, and has done a lot of research for hermit crabs. But here are some things she doesn't know:
1. Which one is easier to care for? Betta fish or hermit crab
2. Will a hermit crab be ok in a five 1/2 gallon tank?
3. Is it ok if she just gets one hermit crab or should she get multiple?
4. And ultimately, which one should she get, hermit crab or betta fish?
The last one is the most important. Thanks!
Answer:
1. Betta Fish
2. Yes. Choose a terrarium that has at least 5 gallons of space per 2 crabs.
3. They require companionship! Hermit crabs, despite their name, are social creatures that thrive best in groups of two or more.
4. Both are entertaining, but I prefer betta. Hermit crabs, in my experience, are extremely sensitive and difficult to keep alive. Hermit crabs proved to be much more difficult than I anticipated, but bettas are a little more straightforward. That is just my opinion; I am sure you will do fantastic with whatever you choose.
I hope this helps you

True or False? A forest of conifers holds more living matter than tropical rainforests.
A. True
B. False
Answer:
true
Explanation:
The statement "a forest of conifers holds more living matter than tropical rainforests" is definitely true.
How do coniferous forests differ from tropical rainforests?Tropical Rainforests undergrowth is evenly distributed. Not much plant growth as very little sunlight passes through the canopy and reaches the forest floor, But coniferous has little undergrowth due to the low amount of sunlight received and the low soil nutrient.
The tropical rainforests have higher and large heights of trees and other vegetation. Due to this, other living matter must definitely be inhibited due to the absence of sunlight.
While in conifers, the height of trees and other vegetation is shortly limited, due to which other living matter also receive a high amount o sunlight. As a result of this, they grow and reproduce successfully.
