The nuclear equation that represents the fusion of two H-2 atoms to form He-3 and one neutron is
In a nuclear reaction the nuclides are represented with the chemical symbol preceded by a superscript that represents the mass number (number of protons plus neutrons) and a subscript that represents the atomic number (number of protons).
<h3>What is a Nuclear reaction ?</h3>
A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

The answer is ‘panthers will become extinct due to the lack of genetic diversity’. The population will enter what is referred to an extinction vortex. This is when environmental, demographic and genetic factors interact and reinforce each other in a downward spiral of a species. The lack of genetic diversity in the population causes inbreeding and lack of diversity on which natural selection can act upon for the population to adapt.
Answer: A
Explanation: A stream terrace basically forms through this process– Temporary base level is eliminated; the stream downcuts upstream from the old temporary base level, and the former floodplain is left well above the present elevation of the stream.
Answer:
a. 8.1 milligrams
b. 40.07 hours
c. 8.859 milligrams
Explanation:
If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by
Where A(t) = amount of Valium remaining in the blood after t hours
t = time or duration after the drug is taken
a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours
= 10×0.81253
= 8.1 milligrams
b. In this part we have to calculate the time when A(t) = 5 milligrams
0.5 = 
Now we take natural log on both the sides of the equation.
ln(0.5) = ln(
-0.69314 = -0.0173t
t = 
t = 40.0658
≈ 40.07 hours
c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.
= 10×0.8859
= 8.859 milligrams
