Answer:

C. You cannot reverse the making of bread. Once it's made it's made.

Explanation:

A chemical change is a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance: The formation of rust on iron is a chemical change.

What conclusion would be most appropriate about the genetic variation between humans and the 3 apes as illustrated by the phylog

GuDViN [60]

I believe the correct answer is that <span>The genetic variation between humans and orangutans is the greatest.
We cannot say that there is no genetic variation at all, because there obviously is - we are not the same as the other three apes, even though we have a common ancestor. Also, we cannot say that we are completely the same, because there are obvious differences. And finally, we didn't originate from those three animals, but rather all of us come from the same organism.

Explain why the concepts of limiting factors and tolerance are important in ecology

Travka [436]

Explain how organisms and the environment cycle matter and energy through these process

nasty-shy [4]

Answer:

When organisms use organic matter for cellular respiration, ALL the matter goes back into carbon dioxide, water, and minerals, while ALL the energy leaves the ecosystem as heat (which is ultimately radiated out into space). So matter cycles, energy flows through ecosystems.

stealth61 [152]

In a DNA molecule, the complementary strand is the one composed of bases that pair -complement- the bases of the original strand. The complementary strand is TACCCGATCAGAA.

<h3>What is a complementary strand?</h3>

During DNA replication, the molecule unwinds and the two strands are separated. These are the original strands.

Once the strands are separated, the elongation process begins, in which new nucleotides are added to complement each of the original strands.

A DNA molecule grows composed of an old existing strand, which is used to synthesize the new complementary strand.

After DNI replication each new molecule carries an original DNI strand and a new one.

So, the complementary strand is the new one composed of bases that pair the bases from the original strand.

In DNA molecules, Adenine pairs Thymine, and Cytosine pairs Guanine.

In the exposed example,

Original strand ⇒ ATGGGCTAGTCTT

Complementary strand ⇒ TACCCGATCAGAA
