Answer:
The correct answer will be option- A and D
Explanation:
<em>E.coli</em> is a bacteria which is pathogenic to humans and<em> E. histolytica</em> is an amoeba which is a parasite. Both are different species but both are single-celled organism which to survive share feature among them.
The common characters shared by these two species are: they depend on the source of energy for their survival which they usually get from the hosts.
Both the species reproduce to produce progenies like them which help them maintain continuity of the species of Earth.
Thus, options- A and D are the correct answer.
Answer:
The correct answer is A. crop rotation.

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
