The right option is; D. Virus are not killed by antibiotics

Antibiotics are unhelpful for treating the common cold because virus are not killed by antibiotics.

Antibiotics are medications that can destroy or inhibit the growth of bacteria. Antibiotics are only used for infections caused by bacteria. Antibiotics do not kill or work on viruses, such as the virus that cause common cold. This is because antibiotics destroy bacteria by directly aiming at its growth machinery but viruses reproduce differently and have different structures. Hence, viruses are not affected by antibiotics.

Eukaryotic cells. Classify each statement according to whether it occurs in eukaryotic cells, prokaryotic cells, or both.
frutty [35]

Answer:

<u>Both</u>:

  • The start codon is often AUG

<u>Eukaryotic cell only:</u>

  • The larger subunit of the ribosome is 60s.
  • The ribosomes initially binds the 5' end of mRNA.

<u>Prokaryotic cell only</u>:

  • The ribosome is 70s
  • Translation occurs in the cytoplasm
  • There are multiple ribosome binding site

Explanation:

  • AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
  • In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
  • Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
  • Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
  • in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
  • Bacterial mRNA contain multiple ribosome binding sites.

Why are both biotic and abiotic features important in ecosystems and biomes?
Sati [7]

Answer:

Hope this is helpful! Sorry if my answer is choppy.

Explanation:

Biotic and abiotic features are both important in ecosystems because for example, a biotic factor like a plant, relies on an abiotic factors like the rain and the sun. If the rain were non existent, then the plants would no longer be alive causing a chain reaction in the food system. Biotic factors like plants and animals that are non existent can also cause negative effects in biomes and ecosystems.
