enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
I think it’s masses (I’m not sure)
Answer:
FALSE
Explanation:
In the periodic table, vertical columns are called GROUPS.
This is a FALSE statement
The horizontal rows on the periodic table are called periods.
Answer:
Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane (Figure 2). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

As plant roots grow, the cells in their tips undergo constant mitosis to produce new
tissue.
