There are 2.16 moles of lithium in 15 grams. Look at the periodic table to find the molar mass.
Answer: 18%
Explanation:
Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio
32% Adenine = 32% Thymine
32 + 32 = 64 100 - 64 = 36 36/2 = 18
18% of Cytosine and 18% of Guanine

I would say that it is...........C) Fossils can help scientists trace physical changes and compare how organisms looked over time
GUARD CELLS are specific leaf structures that regulate the opening and closing of stomata.
These cells are produced in pairs and a stomata pore is formed between them. Swollen guard cells lead to the opening stomata while shrunken guard cells lead to the closing of the stomata.
The swelling and shrinking of the guard cells are caused by the changes of its turgor pressure, which are controlled by the movements of huge quantities of sugar and ions moving in and out of the guard cells.
