Answer:
The technique is known as "staining"
Explanation:
Staining is a technique used to enhance the color contrast of the microscopic samples when observed in the microscope especially in the microbiological samples.
In the given question, when the staining technique is used to identify the sample then staining procedure is followed in a process where the samples can be identified on the basis of the color contrast which is in the case of gram staining.
The gram staining is used to identify the bacteria on the basis of color as the bacteria which appear blue in color are called gram-positive and the bacteria which appear red in color are gram-negative bacteria.
Thus, staining is the correct answer.
Carcinogens is a substance that can cause cancer. So the correct answer is B) cancer

It should be towards. Your welcome
A change in one cycle can affect the other cycles because most ( if not all ) cycles on Earth are related in one way or another.
<h3>How are natural cycles related ?</h3>
The natural cycles on Earth are related to each other because they often draw their energy from the same source which is the atmosphere, the oceans, and the Earth's crust . They also draw their energy from the sun as well .
For instance, the carbon cycle is related to the water cycle because water helps in the transportation of carbon to other areas where organisms can use it . It also helps in the weathering of rocks that contain carbon, thereby releasing it .
This means that a change in one cycle can affect the other cycles in nature if the change interferes with the way that cycle relates to other cycles .
