Answer:
Photosynthesis is defined as the process by which plants make their own food in the presence of sunlight by utilizing water and carbon dioxide and produces energy.
The whole of process of photosynthesis can be represented by the following chemical formula:
6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2
CO2 - carbon dioxide
H2O - Water
C6H12O6 - Glucose
O2 - Oxygen
During photosynthesis glucose is formed from water and carbon dioxide and produces energy which is further converted into pyruvate that releases adenosine triphosphate (ATP) through cellular respiration. Oxygen is also formed.
The process takes place in two sequential stages Light dependent reactions and light-independent reactions.
Pigments in photosystem 1 use energy from light to reenergize the electrons.
Organ system that provides protectionfor the body and maintains homeostasis. (skin, hair, nails) Madeup of Epidermis & Dermis. Theoutermost, thin layer of skin, which contains proteins and is composed of 5 smaller layers of stratified squamous.
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.
