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.

The mantle being made of nickel and iron is the correct statement about the geosphere and is denoted as option B.
<h3>What is Geosphere?</h3>
This is referred to the solid part of the earth and consists of rocky materials present in it.
The geosphere has the mantle which is made up of materials such as iron and nickel which are metals and are responsible for their rigid solid structure thereby ,making it the most appropriate choice.

Answer:
B. Lyme disease is caused by a bacterium and RSMF by a rickettsial agent.
Explanation: Rocky Mountain spotted fever is characterized by a sudden, unrelenting and quickly escalating fever and headache and a rash that usually starts on the wrists and ankles. In contrast, the fever and aches associated with Lyme disease will wax and wane, and the circular rash will go away without treatment.
Diseases spread slowly through the system
Explanation:
It's the only disadvantaged one
