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.
<span>A. light and radio waves
Light is also known as electromagnetic waves. This is because light is actually both an electric and magnetic field. Though it does not seem like it, light does not contain a charge but rather an </span>oscillating field. You can see this happening in your TV. There is no isolated magnetic charge for electromagnetic waves, so you won't be able to do something like put a magnet on the waves.
Triploid organisms are normally sterile as their lack of homologous chromosomes prevents pairing during meiosis. This can be useful to plant breeders, for example in banana cultivation: sterile triploid bananas can be propagated asexually and will not contain any seeds.
This question appears to be incomplete. During blood doping, the athlete will have blood drawn and stored. The athlete will then allow sufficient time for the body to replenish the removed blood. Immediately prior to the event, the athlete will inject the stored blood back into his/her system. Blood doping<span> effectively increases the number of </span>red blood cells<span> in the bloodstream to above normal. This enhances performance because blood cells carry </span>oxygen<span> from the </span>lungs<span> to the </span>muscles<span>, and a higher concentration of oxygen in the blood can improve an athlete’s </span>aerobic capacity<span> a</span><span>nd </span>endurance.
