DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.


All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression  is different (different genes are on or off).

A student prepared a slide of pollen grains from a flower. First the pollen was viewed through the low-power objective lens and
bearhunter [10]

Answer:

(2) low power: 100 small pollen grains

high power: 25 large pollen grains

Explanation:

Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).

For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.

The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.
