<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.
Answer and Explanation:
The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.
Answer:
Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division.
