which of the following abiotic factors can cause harmful effects such as acid rain when too much is releadein to the atmosphere
Kazeer [188]

Abiotic factors can cause harmful effects such as acid rain when too much is releadein to the atmosphere are Carbon, and Sulfur.

<h3>Acid rain</h3>

Acid deposition, often known as acid rain, is a general name for any type of precipitation that contains acidic elements, such as sulfuric or nitric acid, which falls to the ground from the atmosphere in wet or dry forms. This can apply to rain, snow, fog, hail, and even corrosive dust. Sulfur dioxide (SO2) and nitrogen oxides (NOX) that are released into the atmosphere and carried by air currents and wind result in acid rain. Water, oxygen, and other molecules react with the SO2 and NOX to generate sulfuric and nitric acids. While some of the SO2 and NOX that create acid rain come from natural sources like volcanoes, the majority of it is produced by burning fossil fuels.

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.

On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually

<u>the rate of reaction of the enzyme</u>

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?
Afina-wow [57]

The complete question is:

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?

  • Producers
  • Carnivore
  • Herbivores
  • Top predators

Answer: Top predators

Explanation:

The top predators get the least energy because according to the 10 per cent law the energy transfer only 10 energy is transferred to the next successive level.

The next level of the organism receives only 10 of the total energy that the previous level has.

Hence, the top predators have the least amount of energy in it as the energy is transferred through various levels before reaching top predators.
