I cant draw it for you but just look up images of what it looks like an just copy it from that.
Enzymes are affected by temperature and pH in their ability to catalyze chemical reactions. Extreme temperatures and pH values can denature enzymes, causing them to lose structure and function. The active site of an enzyme is sensitive to changes in the local environment, affecting its ability to bind substrates.
Enzymes are subject to influences by the local environment, including temperature and pH. Increasing or decreasing the temperature outside of an optimal range can affect the chemical bonds within the enzyme's active site, making them less suitable for binding substrates.
Extreme temperatures can cause enzymes to denature, losing their structure and function. Similarly, extreme pH values can also denature enzymes and affect their ability to bind substrates.

(B) Ciprofloxacin treatment kills or halts the growth of the sensitive strains, yet the resistant strains survive.
(C) Repeating the treatment of the same patient or a population multiple times results in a strain of Campylobacter that is more susceptible to the antibiotic.
(D) Treatment with ciprofloxacin causes the patient to evolve resistance such that the next time the patient gets an infection, it will no longer be effective.
Answer:
(B) Ciprofloxacin treatment kills or halts the growth of the sensitive strains, yet the resistant strains survive.
Explanation:
Campylobacter jejuni is the causal agent of the food-borne infection with the highest incidence in Europe. Both poultry and wild birds are a major reservoir of the bacteria, the bacteria lives in the intestines of warm blooded animals but is only quite harmful to humans. It has been identified that the diversity fo genes is responsible for its resistance to antibiotics.

Answer:
Plants and animals assimilate carbon-14 from carbon dioxide throughout their life. When they die, they stop exchanging carbon with the biosphere and their carbon-14 content begins to decrease at a rate determined by the law of radioactive decay.
Radiocarbon dating is basically a method designed to measure residual radioactivity.
Explanation:
Carbon-14 is a weakly radioactive carbon isotope; It is also known as radiocarbon, and is an isotopic stopwatch.
Radiocarbon dating is only applicable to organic materials and some inorganic materials (not applicable to metals).
Proportional gas counting, liquid scintillation counting, and accelerator mass spectrometry are the three main methods of radiocarbon dating.
The radiocarbon, or carbon-14, is an isotope of the carbon element that is unstable and weakly radioactive. The stable isotopes are carbon-12 and carbon-13.
Carbon 14 is continuously formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen-14 atoms, rapidly oxidizing in the air to form carbon dioxide and entering the global carbon cycle.
Accelerator mass spectrometry (AMS) is a modern method of radiocarbon dating that is considered the most efficient way to measure the radiocarbon content of a sample. In this method, the content of carbon-14 is measured directly in relation to carbon-12 and carbon-13 present. The method does not take into account beta particles, but the number of carbon atoms present in the sample and the proportion of the isotopes.
