Bases A and T and C and G
b. It is rigid.
c. It is alive.
d. It stretches.gy
The best answer is b - it is rigid.
The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.
The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.
It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
the answer to this question is B because im doing a bilogy test right now as u read this :)

Answer:
Gene expression
Explanation:
The information a living organism needs is embedded in the genes found in the genetic material (DNA) of that organism. These information, however, are stored in the DNA and needs to be used to produce useful products (usually proteins). This process is called GENE EXPRESSION. Gene expression occurs in two steps; transcription and translation.
Transcription is the process whereby the information in the DNA is copied into a RNA molecule. It involves synthesizing a complementary strand of mRNA from a DNA template. This mRNA is then used as a template to direct the production of sequence of amino acids, which determines the protein. Transcription occurs in the nucleus of eukaryotes while it occurs in the cytoplasm of prokaryotes. Translation occurs in the cytoplasm of both prokaryotes and eukaryotes.
