c. Resistant bacteria have survived and reproduced at a greater rate than nonresistant bacteria
Explanation:
The antibiotic is no longer effective as it was 20 years ago because the resistant bacterial have survived and reproduced at a greater rate than the non-resistant bacteria.
- The antibiotics have specifically designed to exterminate the disease causing bacteria strain from the body.
- While at that point in time, it is potent and does the work. Along the line, it will cause the structures of some other strains to change.
- This will lead to the development of resistant breeds with time.
- The resistant breed will then be able to survive the onslaught of the antibiotics making it not a good fit.

Answer:
Information about flowers
Explanation:
1. A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to affect reproduction, usually providing a mechanism for the union of sperm with eggs.
2. Information about stamen and pollen: The stamen is a male reproductive organ of a flower. It produces the pollen. The stamen has two parts: anther and stalk. After successful pollination, the pollen grain (immature microgametophyte) completes it's development by growing a pollen tube and the two male gametes move through the pollen tube to the ovule.
