Answer:
B.
C.
Explanation:
C6H12O6 represents a carbohydrate such as glucose molecule that consist of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. The exact sugar can not be find out because it can have many isomers.
C6H12O6 is hydrophilic in nature because of the hydroxyl (-OH) group. C6H12O6 has the ability to form glycosidic bonds and its polymers can serve as storage or structural components for example starch and cellulose.
The side chain of C6H12O6 might consist of amines or phosphates that would determine its function such as nucleotide.
Hence, the correct answer is "B and C".
Molar mass of C is 12.01g/mol.
Molar mass of H is 1.01g/mol.
Molar mass of O is 16.00g/mol.
If we have 19 atoms of C, 38 atoms of H, and 1 atom of O, then we have:
19*12.01+38*1.01+1*16.00=282.57g/mol
282.57g/mol is the molar mass of the pheromone molecule.
Supposing that "<span>1.8 10-12 g" is 1.8*10^(-12)g then, this quantity of pheromones, shoud be divided by the molar mass of the pheromone molecule:
1.8*10^(-12)/282.57g/mol=6.37*10^(-15)moles
Using now Avogadro's number of molecules in 1mol (6.02*10^(23)) it is possible to know how many molecules are there in this pheromone quantity.
</span>6.02*10^(23)/6.37*10^(-15)=9.45*10^(37)molecules
So, in this quantity of the pheromone there are approximately 9.45*10^(37)molecules of it.
A balanced diet should cover the needs. Iron is mainly present in meat.
Iron needs vary according to sex, age, and physiological status. The recommended dietary intakes are 9 mg per day for men and women breastfeeding and menopausal, 16 mg for women and 25 mg for pregnant women.
Peter had 10.8mg of iron, so yes it is enough for his needs.
Answer: 29.5 days
Hi, i got this answer in my class cause we actually did the same thing.
