Yes, they are perfect flowers.
The molecular mass for C2H4 should be: 2*12 + 4*1= 28 gram/mol. Then the amount of mol in 88.9 grams C2H4 should be: 88.9g/ (28g/mol)= 3.175 mol.
To answer this question, you need to know the reaction formula for the problem. The formula should be:
C2H4 + 3O2 --> 2CO2 + 2H2O
In the formula, every 1 C2H4 will be reacted with 3 O2. Then the amount of oxygen needed would be: 3/1 * 3.175 mol= 9.525 mol
Assuming this is the question that has the four different possible answers, the answer is in fact B: The mouth. Otherwise, I would just say that <em>Any area with said decreased light penetration is going to have less diversity of plant life.</em>

The answer is it will inhibit the-reproduction- of bacteria and viruses. Hope this helps.
Answer:
silviculture should follow natural processes.
foresters should plan for the long-term and science should guide them.
forests have intrinsic value, humans need to extract forest products, and social and economic concerns are important.
