Answer:
Many amino acids in an enzyme molecule carry a charge . Within the enzyme molecule, positively and negatively charged amino acids will attract. This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules
The Douglas fir adapted to enable its survival in the taiga biome due to waxy needles.
<h3>What is Douglas fir?</h3>
Douglas fir may be defined as any type of a genus of tall evergreen timber trees of the pine family having stout bark, pitchy timber, and drooping cones with expanding branching.
Douglas-fir has elongate, narrow, and waxy needle-shaped leaves. The presence of waxy leaves precludes the thrashing of water through the process of transpiration and also controls freezing and leaves drying out.
The complete question is as follows:
How has the Douglas-fir adapted to enable its survival in the taiga biome?
- low growing
- perennial
- waxy needles
- survive on limited nutrients
Therefore, the correct option is C, i.e. waxy needles.
