Bad White [126]

The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.

<h3>What is antibiotic?</h3>
  • Antibiotics from the key class of glycopeptides can stop this process.
  • Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.
  • Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.
  • The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.
  • Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
  • The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.

Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain
docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.

vazorg [7]

Answer:

b.

Explanation:

Based on the information provided within the question it can be said that from this info the researcher can conclude that Dandelion seed number is a constitutive defensive response to rabbit herbivory. This is mainly due to the fact that Dandelions that have been eaten by the rabbits have produced more seeds, meaning that the Dandelions defense mechanism produces more seeds when attacked in order to prevent the flower's extinction.
