Answer:
It is the most abundant
Explanation:
The four most abundant elements by mass in the human body are other nonmetals including oxygen (65%), carbon (18%), hydrogen (10%), and nitrogen (3%). The most abundant of the other nonmetals in the Earth's crust is oxygen which is the single most abundant element in the Earth's crust.
Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.
Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

Answer: B. It is associated with a negative change in free energy.
Explanation:
<u>A polymer is an organic compose made of many simple molecules </u>that are repeating structural units called monomers. Examples of polymers are DNA, lipids, carbohydrates and proteins.
Polymers are broken down into monomers in a process known as hydrolysis, which is a reaction that splits the bond between monomers. During these reactions, the polymer is broken into many components.
This process of breakdown is called catabolic reactions, which, as it was said, is the break down of larger molecules into smaller molecules through the hydrolysis of its bonds. <u>This reaction releases energy which was found in the bond between this monomers.</u> And, when energy is released, there is a negative change in free energy. This means there is more free energy available for the cell to be used.
