Answer:
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
Explanation:
Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
<span>An example of a group of prokaryotic organisms is C. Archaea. There are three domains of life: Archaea, Bacteria, and Eukarya. Archaea and Bacteria are prokaryotic organisms. On the other hand, domain Eukarya includes all eukaryotic organisms, such as Protists, Fungi, Plants, and Animals.</span>
Answer : A metal in group 16 of the periodic table can become a chemically stable ion by gaining 2 electrons.
Explanation :
The group 16 element are oxygen, sulfur, selenium, tellurium and polonium.
The general electronic configuration of group 16 elements is, 
As we now that there are total 6 electrons in p sub-shell. So, a metal in group 16 can become a chemically stable ion by gaining 2 electrons.

Hence, a metal in group 16 of the periodic table can become a chemically stable ion by gaining 2 electrons.
Answer:
what are two parts of the mitochondria?
Mitochondrial matrices and cristae
Explanation:
Mitochondria matrices makes up the spaces in-between the inner membrane while the mitochondria cristae resulted as a result of folding inwards of the inner membrane.
