Answer:
oxygen ion.
An oxygen ion has 8 protons and 10 electrons.
Answer:
The balloon would get larger as it gains water
Explanation:
Due to the process of osmosis, water molecules would passively move from an area of lower solute concentration, the water in the beaker, to an area of higher solute concentration, inside the balloon.
Length: The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system
Mass: Kilogram.
Liquid volume: The basis of fluid volume units for the metric system is the liter. A liter is about the same as one quart.
- The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.
- A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable.
- Experimental constants are values that do not change either during or between experiments.
- A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable.

Answer:
Animals would, instead of getting energy from the food that they eat like meat or plants, they would get their energy from the sun like plants do.
Explanation:
Because like what the paper says, Chloroplasts help with the photosynthesis, which is the process in which a plant gains its energy.

Answer:
17188 years
Explanation:
Recall the formula;
0.693/t1/2 = 2.303/t log(No/N)
t1/2 = half life of 14C
No = initial activity of 14C
N = activity of 14C at time t
t = age of the sample
Substituting values
0.693/5730= 2.303/t log(160/ 20)
1.21 * 10^-4= 2.0798/t
t = 2.0798/1.21 * 10^-4
t = 17188 years
