Answer:

When the heat energy releases and formation of iron oxide.

Explanation:

When the heat energy releases and formation of iron oxide are the indications that chemical reaction takes place. during the steel wool demonstration. During the steel wool demonstration, heat energy released when the iron combine with oxygen forming solid iron oxide. So we can conclude that release of heat energy and formation of iron oxide tells us that the chemical reaction takes place.

Morgarella [4.7K]

Answer:

This statement is true

Explanation:

The genetic code is required for the production of proteins with exception of some few mitochondrial proteins. The transfer RNA (tRNA) acts as an adaptor that enables to associate a messenger RNA trinucleotide sequence (known as anticodon) with its corresponding amino acid in the polypeptididic chain. The genetic code is considered to be a biochemical system capable of revealing the information contained in the DNA in order to synthetize a protein, which has been encrypted in the form of three nucleotides (i.e., codons).

If everyone on the planet used the same amount of
Contact [7]

Answer:

While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.

Then, if the 100% of the population were like the Americans, we have:

5%*x = 100%

x = 100%/5% = 20

the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.

Then the energy that the 100% of the population would use is equal to:

20*24% = 480%

Sowe actually would need like 5 Earths.

So none of the options is matches this, but this may be because this question is about some specific resources and not for the specific energy used. The closest option is 200%

Which of the following best explains how a hurricane can increase an area’s susceptibility to future storms?
spayn [35]
<h3>Correct answer choice is:</h3><h2>d.  Erosion caused by hurricanes can leave coasts more exposed to storms. </h2><h3>Explanation:</h3>

Important erosion, rapture, and removal of solids happen through storms. Beach erosion is a typical consequence of the high waves that transpire when hurricanes pass onto land. The decline of sand makes the beach to grow narrower and deeper in elevation. Storm loops take the sand offshore, keeping and depositing the sediment in great sandbars.

What is the source of carbon for terrestrial plants? terrestrial plants acquire carbon from the .
castortr0y [4]

During this process, plants cleave the carbon from the two oxygen molecules and terminate the oxygen back into the surrounding circumstances.

<h3>What is terrestrial plants?</h3>
  • In terrestrial communities, plants transform atmospheric carbon dioxide into carbon-based combinations through photosynthesis (see above The photosynthetic operation). During this process, plants cleave the carbon from the two oxygen molecules and terminate the oxygen back into the surrounding circumstances.
  • Many terrestrial manufacturers are not even helophytes but rainforest species that tolerate occasional inundation. Examples of these types of plants contain Syngonium, Philodendron, Adiantum, Aglaodorum, Aglaonema, Cordyline, Ophiopogon, and Physostegia.
  • Terrestrial manufacturers are defined as any manufacturer that grows on, in, or from the land. By contrast, aquatic plants are manufacturers that thrive when their roots are submerged in moisture.
