It is usually acetic acid that nature likes to make lipids out of.
Haploid is the correct answer
When a fire is lit, it releases CO2 which will allow the combustion reaction to occur. When a fire is lit, energy is being emitted causing the paper to burn in contact with oxygen. The paper doesn't light up when in usual contact with oxygen because there's not energy fueling the reaction to occur.
Answer:
impulse=force x time
force=mass x acceleration due to gravity
force=
impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)
I converted from kg to g because it is the standard.
Explanation:
The answer is <span>Time is the independent variable, and the number of birds is the dependent variable. </span>
<span>An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In Sam investigation, he controls time - he counts birds at 6 a.m. and 6 p.m. So, time is the independent variable. The number of birds is affected during the experiment, so it must be the dependent variable.
