Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.

<span>Natural nitrogen fixation; An important part of the natural nitrogen cycle were nitrogen gas (N2) in the atmosphere is converted into ammonia (NH3) in in the ground. Some bacteria (diazotrophs), both free living in the soil and in symbiosis with root nodules of some plants, use enzymes (nitrogenazes) to convert the nitrogen into a form that can be used by living organisms.Hope this helps :/

Answer:
The correct answer is option c. "old layers of xylem and phloem".
Explanation:
Wood is one important good used for construction obtained from the main substance of the outer layer of the trunk or branches of a tree. Biologically, the outer layer of the trunk of a tree is comprised of the old layers of xylem and phloem, which are dead cells that were part of the heartwood or the centre of the tree. These old layers of xylem and phloem form the outer bark structure of the tree.
