the answer is option D .size
For this problem, the most probable and the most likely answer for this would be the second option which is cells.
When viewing, not just corks, but other things under a microscope, may it be a home-made one or of something in value or a technologically advanced microscope, small compartments would always be visible under these lenses and they are cells. Some might look like boxes but they are cells. These cells might come in many sizes, but they will always be cells. Cells are everywhere.
Extremely productive, Whittaker was a leading proponent and developer of gradient analysis<span> to address questions in plant </span>community ecology<span>. He provided strong </span>empirical evidence<span> against some ideas of vegetation development advocated by </span>Frederic Clements<span>. Whittaker was most active in the areas of plant </span>community<span> analysis, </span>succession<span>, and </span>productivity. "During his lifetime Whittaker was a major innovator of methodologies of community analysis and a leader in marshaling field data to document patterns in the composition, productivity and diversity of land plant communities."[1]<span> Thus Whittaker was innovative in both empirical data sampling techniques as well as synthesizing more holistic theories.</span>
<u>Answer :-</u> <em>Option 2</em> 90 mm is correct.
<u>Explanation :-</u>
- In the given diagram, we consider the starting point of measurement the value where the mouth of the earthworm is pointed i.e 1.5 cm.
- So if we count from 1.5 cm that is the start point and then we see the end point i.e 10.5 cm we get,
10.5 - 1.5 = 9.0 cm
So the length of the earthworm is 9.0 cm as seen from the scale.
- Now to convert cm into mm, we need to know that:
1 cm = 10 mm
Thus, to convert 9.0 cm to mm
we need to multiply 9 by 10
9 X 10 = 90
So the answer is 90 mm.
