Answer:
C. Respiration.
Explanation:
To respirate means to breath and breathing takes oxygen out of the atmousphere. And it was the only one that made sence.
Answer:
D. Sulfur
Explanation:
Electrons are filled in shells. Oxygen has a total of 8 electrons while sulfur has a total of 16 electrons. Out of the total eight electrons, the first shell has two electrons while six electrons are filled in the “s and p” orbits of the second shell giving the outer shell a configuration of "2s2, 2p4".
Likewise, out of the total 16 electrons of sulfur, the last 6 electrons are filled in "s" and "p" orbits of the third shell. Sulfur has a total of six electrons in its outer most shell "3s² 3p⁴". Since the electrons present in the outer most shell are available for chemical reactions and determine the chemical nature of the atom, oxygen and sulfur should exhibit the same chemical properties.
Answer:
Which cat has the most attractive coat.
Explanation:
Opinions are ideas that are completely subjective (based on how other people feel, not by proven facts) and cannot be proven to be true or false.
The other options can be concretely proven and are thus facts. This is especially true for numerical values. For example, if stated A > B, then it is a fact that A is greater than B.
The question of which cat has the most attractive coat can vary from person to person. I may say that one specific cat has the most attractive coat, while you may disagree and say that another one has a more attractive coat.
Answer:
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
