Answer:
B
Explanation:
The rate of mutations on the S. Aureus population increased when exposed to antibiotics over time. This gave rise to a few mutants of the bacteria that could survive the methicillin antibiotic. This is because the mutation altered a protein target of methicilin (beta-lactam binding proteins) on which the antibiotic acted upon. These populations increased as the others were eliminated by the antibiotic – the way natural selection works. Over time, these mutations were transferred to other populations of bacteria by these MRSA through ‘sexual’ horizontal gene transfer, causing whole bacteria populations to be resistant against methicilin.
Answer:
C. Organism living in the fallen trees lose shelter.
Explanation:
talking about the effects of storm winds falling trees, it creates more light to reach shorter plant which will help the plants to do photosynthesis well, which will even facilitate their fast growth; that's positive.
Fallen trees becoming food for decomposers can also be positive cause this will help the soil or earth of that forest have fertility
New Clearing attracting animals such as man can lead to extinction of forest which to conservators they feel like no-no-no-no that's they'd see it as a negative consequence of the wind storm effect, yes this can lead to de-sheltering of organisms inhabiting that niche(trees)
Correct answer: C). Sunlight is converted to chemical energy
Sunlight is used in the process of photosynthesis by the plants to make glucose and six molecules of oxygen.
During the process of photosynthesis plants capture sunlight with the help of chlorophyll pigments which are present in their leaves. The light energy trap by plant is used to change water and carbon dioxide into the form of sugar called as glucose.
This glucose is used by the plants as a energy to make cellulose and starch . Cellulose is used as the building material for cell wall and starch is stored in seeds and other parts of the plant as a food source which is used by heterotrophs as a food source.

in the main reproductive hormones are oestrogen and testosterones. Œstrogènes causes eggs to mature in overuse once a girl hits puberty. These are then released at regular intervals during the menstruel cycle
