<h2>
A change in one base of the gene sequence is known as point mutation.</h2>
Explanation:
Question 2 is incomplete.
3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.
In Point mutations there is substitution of one base for another.
Example: TAT TGG CTA
TAC TGG CTA
The TAT changes to TAC which shows point mutation.
4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.
When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.
Answer:
Two or more elements,
Two or more elements,Chemically combined elements,
Two or more elements,Chemically combined elements,More and definite proportions.
Explanation:
A compoundcan be definedas a substance which is composed of two or more elements, that are combined together chemically.
These constituents elements are present in definite proportion and quantities. The composing elements of a compound can be separated only by the means of chemical procedures. A compound is composed of more than one type of atom.
Hence answer could be:
Two or more elements,
Two or more elements,Chemically combined elements,
Two or more elements,Chemically combined elements,More and definite proportions.

Explanation:
Im pretty sure, so sorry if I'm wrong though.
Cell is the structural and functional unit of life. All living organisms are made up of cells. The size of any living cell is limited. Limited cell size has many advantages.
Answer: Analogy to explain why cell size is limited is SMALLER THE SIZE OF A CELL LARGER WILL BE THE SURFACE AREA TO VOLUME RATIO.
Answer:
The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.
Explanation:
Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.
