An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>

<u />

Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.

Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.

Wind power, water power (also called hydroelectricity), solar power, ethanol:
lora16 [44]
Wind power:

Advantages:

-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.

-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.

-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.

Disadvantages:

-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.

-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.

-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.
