What objective lens will you use if you want to observe the whole structure of a pollen ? explain your answer.2.what will you do. if the specimen you are observing under the microscope is blurry? what part of the microscope will you move in order to see the specimen clearly? explain how.3.you cannot see some of the parts of your specimen in the microscope because of too much brightness .what part of the microscope will you adjust to see part of the specimen ? explain how.

1. In compound light microscope there can be seen more than 1 objective lenses. The magnifications of those normally would be 4x, 10x, 40x and 100x. To see the whole structure of the specimen you should focus your microscope with the lowest power objective lens which means 4x.

2. If the specimen you are observing under the microscope is blurry, then you should do fine focusing until you get the clear image of the specimen. The fine focus wheel normally is attached to the arm of the microscope.

3. If your specimen in the microscope is too much bright, then you should reduce the brightness until you can see the specimen clearly. The brightness is caused by the light. To control the light you have to adjust the condenser of the microscope.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

the answer to your question is c.
