The correct answer is A
The scientist can determine that this nucleic acid is a DNA molecule, because it contains Thymine, which does not occure in the RNA molecule. The RNA molecule contains Adenine, Guanine and Cytosine just like the DNA, but unlike the DNA it contains Uracil, not Thymine.
Secondly, the scientist can say with certainty that this DNA molecule is surrounded by a nucleus based on the structure of the nucleic acid described. Only eukaryotic cells have ladder structure. The prokaryotic cells have circular DNA and do not have any organelles, like the nucleus. Therefore, from the ladder structure of the DNA the scientist can see that the cell has a nucleus.
Answer:
thermal energy - produced by the movement of heat
radiant energy - produced by the movement of photons
electrical energy - produced by the movement of electrons
sound energy - produced by vibrations of particles
Explanation:
Thermal energy is also known as heat energy. It occurs when heat is transferred in an object.
Radiant energy involves the movement of photons (particles with electromagnetic energy)

Answer:
Option A.
The best way to carry out smart growth is by keeping neighborhoods walkable.
Explanation:
- Smart growth is an unique concept that avoids sprawl by urban framing plan and transportation theory.
- For the smart growth of the community there must be compulsorily availability of walkable spaces in a compact urban centers.
- This tool of smart growth helps in developing the cities by preserving the available spaces for tomorrow, this process is also known as the sustainable development.
