A.genetic modification of food helps it grow more easily in certain areas
Explanation:
The statement genetic modification of food helps it grow more easily in certain areas is a form of agricultural research that is very accurate.
Genetically modifying food is common practice in order to encourage desirable and sustainable traits in plant species.
- Drought resistant breeds can tolerate a much lower level of water in some specific areas.
- Disease resistant breeds are more adapted to outbreaks of plant epidemics.
- Overall, genetic modification of food helps them to grow and produce better.

Answer:
c 18.0ml
Explanation:
The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.
Answer:
403 mL
Explanation:
First, I will assume that the mole is 1, because you are not specifing this.
Now, with the innitial data, we need to get the pressure:
T = 65+273 = 338 K
V = 500 / 1000 = 0.5 L
Now if:
PV = nRT
Then:
P = nRT/V and V = nRT/P
Let's calculate the P:
P = 1 * 0.082 * 338 / 0.5 = 55.432 atm
The standard temperature is 0° C or 273 K so, the volume is:
V = 1 * 0.082 * 273 / 55.432
V = 0.40384 L or simply 403.84 mL
