<h2>Order of parts of a microscope
</h2>
First – ocular lens
Second – Body tube
Third – Revolving Nosepiece
Fourth – Objective lens
Fifth – Coverslip
Explanation:
Ocular lens: The lens present in the eyepiece at the top of the microscope, close to the eyes, through which a person looks through the microscope to view the specimen. Magnification of ocular lens in a compound microscope is usually 10x
Body tube: The tube that connects the eyepiece with the objective of the microscope for continuous optical alignment.
Revolving Nosepiece: The turret that holds the objective and revolves to select the objective lens according to its magnification
Objective lens: The objective lens is located above the specimen rack. Objective lens creates the primary image of the specimen viewed through the eyepiece. A single compound microscope can have more than two objective lens and their magnification ranges from 4x, 10x, 40x, 100x power.
Coverslip: The cover glass which covers the objective lens and prevent from touching the specimen
. This is the object directly above the specimen.

The rotation of the earth around the sun
Ecological efficiency is the term used to describe how much energy will be passed from lower food pyramid level into the higher level. The amount of energy in primary level will be much higher than tertiary. The difference of level of tertiary(3) with primary(1) would be two level.
Assuming that the ecological efficiency is 10%, then the <span>primary consumer level would be: 50 kcal * 10^(3-1)= 5000 kcal</span>
Answer;
ADP
Explanation;
-ATP molecule actsas the major energy molecule used by the cells. ATP synthase located in the inner membrane of the mitochondria, catalyses the formation of ATP, as a result of protons concentration gradient.
-The enzyme generates ATP from adenosine diphosphate and an inorganic phosphate through a process called oxidative phosphorylation, which is the process by which enzymes oxidize nutrients to form ATP.
