Answer;
Key
A sorting device that is useful in classifying by observation is a key.
Explanation;
Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms.
They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
Therefore, keys can be used to identify a living organism or determine which group it belongs to by answering questions on the key about characteristics of living things.
b. monomer.
c. disaccharide.
d. polysaccharide.
Glucose is a monomer, a molecule that can join together with other molecules to form a larger structure such as a polymer or polysaccharide.
Glucose is classified as a monomer. In the context of biochemistry, a monomer is a molecule that can join together with other molecules to form a larger complex, known as a polymer. Examples of polymers include proteins, nucleic acids, and polysaccharides. However, glucose itself is a simple sugar and acts as a building block for these larger structures. As such, it is a monomer, not a polymer or a polysaccharide. It is also not a disaccharide, which is a sugar composed of two monomers, such as sucrose (a disaccharide made of glucose and fructose).

Answer:
firsttttttttttttttt.........................
The correct option is D.
A virus refers to an infectious micro organism that is made up of nucleic acid molecule that is enclosed within a protein coat. Viruses are only able to reproduce and multiply when they come in contact with living cells, in the absence of living cells they remain dormant and they do not show any sign of been a living thing. The nuclei acid molecule of a virus can be in form of a DNA molecule or a RNA molecule.
Answer: The answer is D/RNA or DNA core surrounded by a protein coat.
Explanation: One reason a virus is considered to be a particle rather than a cell is because structurally it is only a RNA or DNA core surrounded by a protein coat. It has none of the other features of bacterial cells.
