A propane molecule's structure can be understood through the ball-and-stick model where carbon and hydrogen atoms play distinct roles leading to different alkyl groups.
The ball-and-stick model of a propane molecule is built using black spheres to indicate carbon atoms and white spheres for hydrogen atoms. In propane, each of the six equivalent white spheres (hydrogen atoms) are bonded to a black sphere (carbon atom) connected to one other black sphere (carbon atom). The remaining two hydrogen atoms are of a different type as they are bonded to a carbon atom (black sphere) that is bonded to two other carbon atoms. They are represented as purple spheres in this explanation. Adjacently, in 2-methylpropane, we find nine similar hydrogen atoms, but notably, one that differs - represented as a green sphere which is bonded to a carbon atom connected to three other carbon atoms. This unique arrangement allows for the formation of different alkyl groups when certain hydrogen atoms are removed.

Several natural products have been isolated from the flowering plant Sacrostemma acidum, which has been used in folk medicine as a cough suppressant.
Nаturаl products hаd been used by mаny cultures аnd trаditions from thousаnds of yeаrs for their bioаctive phаrmаcophores by modern phаrmаceuticаl compаnies. The potentiаl bioаctive phytocompounds such аs аlkаloids, flаvonoids, phenolic compounds, аnd steroids аre potentiаl source for drug discovery.
Sacrostemma acidum has been used in folk medicine as a cough suppressant. Acidum stem extrаct resulted in аn аrrest of spermаtogenesis without аny systemic side effect. Sperm motility аs well аs sperm density wаs reduced significаntly.

(2) It requires an external energy source.
(3) It uses radioactive nuclides.
(4) It undergoes a spontaneous redox reaction.
O A. The theories of motion became laws after there was enough
evidence to prove they were true.
O B. The laws cannot be tested by experiments, but scientists know
that they are correct because they make sense mathematically.
c. The laws explain how objects move and are supported by
experimental evidence.
O D. The laws describe a wide range of observations of motion and can
be used to predict the motion of objects.

Answer:
D
Explanation:
Scientific laws describe how things work with little to no exception. They do NOT provide an explanation to WHY something occurs.
Answer:
The answer is D because scientific laws describe how things work not why they happen.
