Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
Answer:
Presence of an enzyme
Explanation:
Enzymes are the biomolecules present in cells. The enzymes serve to catalyze the chemical reactions that occur inside the cells. Enzymes speed up the rate of the chemical reaction and allow the formation of products at a fast rate. This is done by lowering down the activation energy that is required to begin a chemical reaction. This energy breaks down the older bonds present in substrates so that new bonds can be formed. Enzymes lower down the activation energy to speed up the reactions.

B. Some people find it unattractive.
Explanation:
Ap3x
Answer:
A healthy radish plant growing in a greenhouse is covered with a screen box that blocks sunlight. After 10 days, the mass of the plants has <u>decreased</u> because the rate of cellular respiration is <u>higher than</u> the rate of photosynthesis.
Explanation:
If a healthy plant would be covered with a screen box for a period of 10 days, the rate of photosynthesis would be decreased significantly. We know that a plant essentialy needs sunlight to perform photosynthesis. Further, when the photosynthesis is already stopped, the <u>cellular respiration would continue and the plant would loss most of its water content</u>. Ultimately, after a few days, the plant biomass would start decreasing as well. The period of 10 days is sufficient enough to see the loss of plant biomass and decrease in photosynthesis rate. Normally, results are evident after 24 hours.
