FALSE
In the currently accepted atomic model, an electron orbits around the nucleus is NOT in a clear, defined path.
Explanation:
According to modern atomic models, like the Bohr theory, it is difficult to know the exact location and path of an electron around the nucleus. This is partly because the mere act of observing the electrons changes its position. This is because the electrons have negligible mass and therefore ‘hitting’ them with any form of radiation for ‘illumination’ changes its position, behavior, and properties. In addition, the movement of electrons is very rapid such that by the time one observes the instantaneous location of an electron, if it was possible, it will have changed its position.
Therefore modern theories, such as VSPER, model atoms based on properties of where an electron will highly likely be found. This is how the shells and subshells of electrons (s, p, d, f) are modeled.

Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer
Explanation:
This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:
CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.
Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).
<span>Fats, oils and cholesterol are all types of lipids.Lipids are biomolecules that consist in long chains of carbons and hydrogen, insolubles in water (becauise they are not polar). Many lipids have in common the functional group corboxilic, COOH. Cholesterol, fats and oils all have carboxlic group. </span>
D. secondary
Two groups: primary and secondary
The primary groups has stronger and deeper relationships with its member/s than secondary groups, many of which are superficial gatherings and surface dealings.
Primary groups include:
1. Family
2. Lover
<span>3. Husband/Wife </span>
Secondary groups:
1. Colleagues
2. Classmates
3. Friends
<span>4. Acquaintance</span>
