<em>It is beneficial because it provides stronger support for the evidence related to the discovery</em>
<u>Answer:</u> <em>The correct answer is the second option that is given with shows it is beneficial.</em>
<u>Explanation:</u>
The discovery of an element whose properties are known from before would make it easier for the scientists to know the properties of elements and its uses after the discovery of element.
Since the elements’ properties are already known as element that possesses these properties and will look forward to find that and once the element is found the element can be named and can be used directly, since its uses are already known.

C. seaborgium: atomic number 106, mass 266, neutrons 160
Explanation:
An atom is made up three fundamental particles:
- Protons are the positively charged particles in an atom
- Electrons are the negatively charged particles
- Neutrons carry no charges.
The mass number is the sum of protons and neutrons in an atom because they contribute to the mass of an atom.
The atomic number is the number of protons in an atom. For a neutral atom, it is the same as the number of electrons.
Number of neutrons = mass number - atomic number
For seaborgium,
Number of neutrons = 266 - 106 = 160
This is the only correct option given.

Answer:
Prokaryotic cells don't have a nucleus, so its false.
Answer is: A. food chains.
Plants convert solar energy into the chemical energy of sugars (food).
Solar energy is stored in chemical bonds of sugars (glucose for example).
The overall balanced photosynthesis reaction:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
In carbon dioxide, carbon has oxidation number +4 and in photosynthesis carbon gain electrons (solar energy), so his oxidation number is lowered (reduced). Light energy is transformed into chemical energy, that is stored in carbohydrate molecules (glucose), which are synthesized from carbon dioxide and water.
