Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.
1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.
2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.
3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.
4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.
Answer:
the orientation of Earth's tilt with respect to the sun – our source of light and warmth – does change as we orbit the sun. In other words, the Northern Hemisphere is oriented toward the sun for half of the year and away from the sun for the other half.
Explanation:
It tells the audience if the results support or contradict the hypothesis
Explanation:
When a scientist describes the materials that she used and how she performed her experiments, it tells the audience if the results supports or contradicts the hypothesis.
- A hypothesis formulation helps to test a scientific claims.
- Experiments are usually hinged on well designed hypothesis.
- From the hypothesis, one can be sure the experiment is tuned and designed within the scope of the observation desired to be tested.
- This is why the materials used and procedures followed in an experiment can tell if the results supports or contradicts the hypothesis.
