what are the different parts of microscope ?

A microscope is which produces large images of tiny  substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.

Anatomically the microscope consist of  three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.

Base of microscope is used to support  and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.

The optical parts are basically applied for the  view, magnify, and production of an image from a specimen placed and the various parts.

Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

Why is it important to have a control group in the experimental design?

Answers

The control group is the main one because it acts as a benchmark to balance the results of the experiment.

What is control group in the experiment?

Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.

So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.

What is the use of reverse transcriptase?

Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.

Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and  DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.

The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.

Therefore, The mRNA sequence will best match the section of DNA shown below is  C-U-A-G-G-A. Thus, option C is correct.

Why does cell size need to be limited?

Where does the DNA come from that is in the parent cell?

Answers

Answer:

Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.

The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.
