Lactase and carbonic anhydrase are examples of what type of substance?
substrate
reactant
product
enzyme

Answer 1

1) hypotonic — water enters the plant cells, increasing turgor (firmness).

2) gametes — sperm and egg cells are gametes.

3) metaphase — chromosomes are lined up at the cell center (metaphase plate).

4) dominant — purple is the dominant trait.

5) enzyme — both lactase and carbonic anhydrase are enzymes.
