Tropical rainforest is a biome which is warm and wet, with little seasonal variation in temperature and frequent precipitation.
<h3>What is a Biome?</h3>
This is referred to an environment which has features such as being greatly influenced by abiotic factors such as sunlight, water etc.
Tropical rainforest as the name implies has a large and frequent amount of precipitation thereby making it wet with little seasonal variation in temperature. It is also characterized by large trees which form canopies in the region.

Answer:
The functional groups determine the shapes of macromolecules and this in turn determines their functions.
Functional groups affect the bonds that hold a macromolecule together. For example, the ring forms of glucose in starch and cellulose have different configurations. As a result, cellulose and starch serve different purposes.
Functional groups also affect the polarity of the bonds. Lipids consist of hydrophilic heads (red) and hydrophobic tails (black and white). This characteristic of lipids allows them to form bilayers, which serve as membranes of cells.
Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.
Explanation:
The enzymes that are used to replicate a virus are synthesized by the host cell. That is option A.
<h3>Process of viral infection.</h3>
A virus is a microorganism that has the ability to reproduce only by infecting a living host.
The main features of a virus include:
- nucleic acid genome ( RNA or DNA)
For a virus to be able to cause an infection,it has to pass through the following steps:
- Attachment of the virus to the host cell.
- Entry of the viral genetic material into the host cell
- Genome replication and gene expression: through the ribosomes of the host cells, enzymes are released which are used to replicate the invading virus to produce new ones.
Therefore, the enzymes that are used to replicate a virus are synthesized by the host cell.
