Answer: Option (4) is the correct answer.
Explanation:
In a nuclear power plant, nuclear fission and fusion reactions occur.
During these reaction a large amount of heat is releases along with the release of radioisotopes. These radioisotopes have long half-lives as a result these emit harmful radiations which can either cause burns or blindness to the people around the nuclear power plant etc.
For example, isotope of Uranium-238 have longer half life.
Thus, we can conclude that a serious risk factor associated with the operation of a nuclear power plant is the production of radioisotopes with long half-lives.
The major risk associated with the operation of nuclear power plants is the generation of radioisotopes with long half-lives, such as cesium-137 and strontium-90. These remain harmful for thousands of years.
A serious risk factor associated with the operation of a nuclear power plant is the production of radioisotopes with long half-lives. Apart from the immediate dangers posed by nuclear accidents, these radioisotopes, such as cesium-137 and strontium-90, remain radioactively harmful for a long period of time, often thousands of years. Safe containment and disposal of these substances is a significant challenge associated with nuclear energy production.
In contrast, acid rain is generally caused by burning fossil fuels, not nuclear power. Nuclear power plants do not produce significant amounts of greenhouse gases such as CO2. Helium gas is one of the byproducts of nuclear fusion, not fission, which is used in nuclear power plants, and is not dangerous.

(2) more effective particle collisions occur
(3) the required activation energy increases
(4) the concentration of the reactants increases
one that results in lighter flower petal colors without changing the plant’s ability to reproduce
one that causes a person’s body to produce thick mucus that clogs the lungs
one that makes it easier for a corn plant to contract a disease
Mutation can be defined as the change in the genetic sequence that is hereditary. The example of beneficial mutation can be the change of rabbit color to help him hide from the predators.
The mutation can be caused by the exposure of the gene sequence to the mutagen that cause the hereditary change.
The mutagens can be UV radiation, high energy, radiation, chemicals, or environmental factors.
The beneficial mutation can be given as the mutation in which the organism has been benefitted. The change in the color pf rabbit benefit him in hiding from the predators. Thus, option A has been the example of the beneficial mutation.

Explanation:
silicon
lead
bismuth
Bismuth will not have the same number of valence electrons.
Valence electrons are those that are found in an atom's outermost electron shell. These electrons are involved in bonds and reactions because they are the farthest from the nucleus and as a result are less tightly held by the atom.
This implies that an element's reactivity, electronegativity, and the number of bonds it may form are all dependent on the number of valence electrons it possesses. The ability of an element to create bonds with other atoms is referred to as valence.
The number of hydrogen atoms an element can bond to (which is determined by how many valence electrons are available for bonding) has historically been used to determine an element's valence.
Therefore, Bismuth will not have the same number of valence electrons.

Answer: The correct answer is bismuth.
Solution:
Bismuth is the member of group 15 of the periodic table.
Bismuth contains five valence electrons in its valence shell. Which can be seen from its electronic configuration:
Where as other three elements are the members of group 14 of the periodic table with three valence electrons in their respective valence shells.
