The answer is b. Our body is made up of water and so we need to refresh our body from time to time by bringing more water in. The water in the air also helps us get oxygen. Plants take the water and sunlight to do photosynthesis which creates oxygen so we can breathe

D.The moon’s orbit must cross the plane of the ecliptic
Answer:
a) 0.56moles
b) 2.78moles
Explanation:
The number of moles can be calculated by using the formula;
Mole (n) = Mass (M) ÷ Molar mass (MM)
For a glucose molecule, with chemical formula: C6H12O6
Where atomic mass of C= 12, H=1, O= 16
Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)
= 72 + 12 + 96
= 180g/mol
a) In 100g of glucose;
Mole = 100/180
Mole = 0.56moles
b) In 500g of glucose
Mole = 500/180
Mole = 2.78moles
Answer: Independent variable is what is being modified, it is important to compare it to your control group, (which is the original).
Dependent variable is what is being measured, to compare it to the control group to see if your hypothesis works or not.
Explanation: Here's a(n) example:
Bob wanted to take a mint with a mint drop, and he wanted to measure if it can make his breath fresher, but he also wanted to take it with a regular mint to see which is the freshest breath.
Independent variable: Mint drop.
Dependent Variable: Breath (To see if it is going to change with a mint drop.)
Control Group- Regular mint.
Plants and animals could not live without nitrogen<span>. It is an </span>important<span> part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy. hope this helps!</span>
