Answer:

3. An Apple Turning Brown

Explanation:

When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

Answer:

I believe It's 3. If it isn't it's probably 4, because that also has to do with change. (If I'm being honest none of these really pertain to oxidation, since it has to do with weathering things but eh.)

Hope I could help!

labwork [276]

Answer:

Life cycle of a moss

Explanation:

LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE

An embryo further develops into a pear-shaped  sporangium, which is the *sporophyte  stage of the plant*. The sporangium  contains spore sacs, each of which is the spore mother cell that undergoes meiotic division  to form four spores,The spores are released and germination

takes  place giving  rise to a protonema, which develops into a new gametophyte plant. The gametophyte  generation or haploid phase of the moss is from the production  of haploid spores after meiosis  to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid  phase is from the diploid  mother cells just before meiosis.

Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.
