WORKING DISTANCE is space between the bottom of objective the lens and the surface of the slide.
The distance between front edge of the objective and the lens and the specimen surface ("with the surface of the cover glass in case of the cover glass objective lens") when the specimen is also focused.
The working distance (W.D.) which is determined by the linear measurement of the objective and front lens to the focal plane. In the general, the objective of the working distance decreases by the magnification and the numerical aperture of both increase. The working distance is the distance and from the front of the lens to be the focal plane

According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.
<h3>What is the kingdom protista?</h3>
It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.
Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.
Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.

Because it is polar and it is to large to cross the membrane and because the concentration gradients are to strong so they have to be diffused.

I believe the answer would be B.
<span>In a hydrolysis reaction, water (H2O) is added to a bond and cleaves the bond holding molecules together, breaking polymers into 2 pieces. In total, you take a water molecule and split it among the two parts, H+ and OH-. These ions get added to either side with the higher affinity for the cation (H+) and anion (OH-). </span>
