Answer:
D.
I remember doing a question like this in class while learning about natural selection. The 2 colorations of moth live in a habitat that originally supported the lighter variant due to the light-colored trees. When the industrial revolution began, the soot levels reversed this because the black moths were more camouflaged that the lighter ones. A way we could prove this was the amount of black dresses and dark colored clothing during the time, often due to the fact that lighter colored clothing would turn black by the time the wearer arrived home. The lighter colored moths simply died off a bit because of this.

Answer:
B) Hypogranular neutrophils
Explanation:
Myelodysplastic syndrome occurs due to a disordered production of blood cells in the bone marrow that die before they are even released into the bloodstream. This syndrome is of great clinical significance as they may progress to Acute Myeloid Leukemia. Generally, when this disease has pre-leukemic features it may include hypogranular neutrophils which is one is a feature of neutrophil dysplasia commonly observed in myelodysplastic syndromes.
Answer:
The observed image will not be sharp
Explanation:
When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).
