In the experiment, the independent variable is the drug amount. Experiment group is given certain amount of drug, control group is not given the drug. The dependent variable is the body fat. I think you means the control is the living environment including food and water.
Answer:
The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation.
Explanation:
<span>1. One common interaction between biotic and abiotic components of an ecosystem is photosynthesis.
Sunlight is abiotic (solely energy), and it fuels the synthesis of
sugars and proteins inside plant cells once it is taken up by plant
leaves. </span><span>This process also produces oxygen.

2. Biotic factor that can affect the size of a population in a specific ecosystem:
<span>Number and kinds of predators in the ecosystem.
</span><span /><span>
Predator-prey relationships
When the
moose population is high on Isle Royale, the wolves have more food
source from preying on the moose. This supports an increase in the wolf
population.</span>

3. Temperature
You can change the temperature to freezing it will affect the aquarium because the organisms will not be able to tolerate the new environment if they are species that thrive in warm temperatures.

Explanation:
The half life is the time taken for a half of a radioactive material or substance to decay to half.
After the passing of the half-life, only half of the original material will remain. Now, let us follow the half-life sequence of this decay;
One half-life
Original: 1000cm
one half life = 500cm
Two half-lifes
Original: 500:
half-life = 250cm
Three half-lifes
Original : 250cm
Half life = 125cm
Four half-lifes
Original: 125cm
Half life = 62.5cm
Five half-lifes
Original: 62.5cm
Half-life = 31.25cm
Six half-lifes
Original: 31.25cm
Half-life = 15.625

Identifying the parts of the resulting sister chromatids that will be radiactive is possible with use of radioactive dye and Xray photography. By using radioactive dye and bonding agents, we can identify particular stretches of DNA that corresponds to certain amino acids sequences.
