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.

<h3><u>Answer;</u></h3>
Lithosphere
<h3><u>Explanation</u>;</h3>
- Lithosphere is the solid outer part of the earth which includes the brittle upper portion of the crust and the mantle. It is bounded by the asthenosphere below and the atmosphere above.
- <em><u>The pressure in the lithosphere is about 109 gigapascals or GPa. </u></em>
- <em><u>Asthenosphere has a pressure of about 18 GPa</u></em>
- <em><u>The mantle is a layer between the outer core and the crust, it has a pressure of about 149 GPa.</u></em>
Answer:
reactions
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
