<span>The answer is: more protons than neutrons
The stability of the nucleus is based on the ratio of neutrons and protons present in the nucleus. if the number of protons is equal to the number neutrons then the nucleus
is stable but in case the number of protons is more than the number neutrons or the other way round the nucleus to gain stability starts interconversion of neutron to proton
or electron or decreases proton numbers. In case of nucleus containing high energy, the nucleus releases it. Such nuclei which release energy to gain stability are called
radioactive nuclei and the phenomenon is called radioactivity.</span>
The question is incomplete: the complete question is:
Rank molecules or group of molecules by when mammals use as fuel, starting right after meal to only through?
starvation.
a) glucose from glucose-2-phosphate from glycogen.
b) free glucose and amino acids
c) fatty acids from triglycerides
d) glucose produced from amino acids in liver.
Answer:
B
A
C
D
Explanation:
Free glucose and amino acid enters into the blood stream directly and can be used immediately after meals by mammals.
The liver stores excess glucose as glycogen, hence when glucose levels begin to reduce in the body, the pancreas releases glucagon which converts glycogen to glucose.
Triglycerides are broken down to give fatty acids which gives much more energy than glucose.
During starvation, amino acids in the liver is converted to glucose when a person goes for days without eating.
C₈H₁₈ is a non-electrolyte
Why?
Electrolytes are substances that dissociate into ions when dissolved in water. In order to do that, they need to have bonds that are polar enough to be able to dissociate, and the ions formed need to be soluble in water.
C₈H₁₈ is a compound that has a low electronegativity difference between its atoms, making it to be a covalent compound where electrons are shared, and making it non-polar, and difficult to dissociate. Thus, it is a non-electrolyte.
One possible structure for C₈H₁₈ is attached below. It's called octane.

Answer:
Ionic
Explanation: Ionic compounds tend to be hard and brittle while covalent compounds tend to be softer and more flexible.
