What group of organisms are responsible for capturing energy within ecosystems
Marina86 [1]

The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:

1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit

2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake

3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)

Alcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH3OH) into nontoxic substances. Methy
Thepotemich [5.8K]

Answer:

d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.

Their active sites are primary protein  3D structure  for binding with substrates during   reactions.

Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,

This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites  occupied, therefore denying the inhibitor methylalchol  chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites

What factors go into calculating an ecological footprint
zzz [600]
<h2>Ecological Footprint</h2>

Explanation:

  • <em>The Ecological Footprint</em> of an individual is determined by including the entirety of individuals' requests that vie for organically gainful space, for example, cropland to develop potatoes or cotton, or <em>backwoods to create timber or to sequester carbon dioxide outflows.  </em>
  • The national normal or per capita Ecological Footprint of utilization is equivalent to a <em>nation's Ecological Footprint of utilization isolated by its populace.  </em>
  • As indicated by the Global Footprint Network, the Ecological Footprint for the normal American is 8.6 gha, more than twofold Brazil's normal of 3.1 gha and Mexico's normal of 2.6 gha.  Check The month to month service bills.
  1. <em>Increase your kilowatt hours by 1.85. For instance, 67 hrs X 1.85 = 123.95 lbs of CO2.  </em>
  2. <em>Increase your flammable gas use (therms) by 13.466. For instance, 19 therms X 13.466 = 255.854 lbs of CO2.  </em>
  3. <em>Increase gallons or propane utilized by 13.  </em>
  4. <em>Increase gallons of fuel utilized by 22.</em>

Why are offspring of organisms that reproduce sexually not genetically identical to their parents
Nat2105 [25]

Answer:

The offspring of organisms that is reproduce through sexually are not genetically identical to their parents because the offspring contains genes from two parents.

Explanation:

Identical offspring is only formed when offspring is produced from one parent through asexual reproduction such as building, binary fission and fragmentation. In sexual reproduction, offspring is produced by the mating of two organisms i. e. male and female organism. That's why genes of offspring are different from their parents and offspring is not identical to parents.
