What is the relationship between temperature and kelp productivity?
jasenka [17]

Answer: As the temperature of the water goes up, the amount and spatial extent of the kelp goes down. These changes could result in dramatic habitat loss leading to reduced ecosystem productivity and the extinction of many invertebrate species.

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.

During the light dependent reaction of photosynthesis light energy is converted into which form of energy
Hoochie [10]

Answer: Chemical energy

Explanation: During light dependent reactions of photosynthesis, light is absorbed by chlorophyll and other light absorbing pigments. The light energy absorbed is conserved as ATP and NADPH. In light dependent reactions, the light energy is used to split water molecules into hydrogen ions and oxygen molecules and consequent production of ATP and NADPH. This reaction is called photolysis of water. The oxygen molecules is evolved while the hydrogen ions are transferred to NADP+ to produce NADPH. In light dependent reactions, ATP and NADPH are produced.

ATP and NADPH are forms of chemical energy which are usable in the cells. Therefore, light energy is converted into chemical energy in light dependent reactions of photosynthesis.
