Answer: Option (c) is the correct answer.
Explanation:
When energy is supplied to an electron then on absorption of energy it tends to move from a lower energy level to higher energy level.
And, when this electron moves from higher energy level to lower energy level then excess of energy absorbed by it is released in the form of visible light or radiation.
This emission of energy is also responsible for imparting color to a compound.
Thus, we can conclude that electron gains energy when an electron moves to a higher energy level.
Answer:
The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).

b. producing flowers
c. being a prokaryote
d. being an autotroph
The correct option is d. being an autotroph. All plants are multicellular eukaryotes that produce their food through the process of photosynthesis.
Autotrophs are organisms that are capable of producing their own food using energy from the environment, such as sunlight or chemicals. They are also known as "producers" in ecosystems because they are able to synthesize organic molecules from simple inorganic substances.
Plants are one of the most well-known examples of autotrophs, as they use energy from sunlight to produce their own food through photosynthesis.
Not all plants produce flowers, as there are some plant groups that do not produce flowers such as ferns and mosses. Additionally, plants are not unicellular as they are made up of many cells. Finally, plants are not prokaryotes, as they have complex cells with a nucleus and other organelles.
Hence, option d is correct.

b. NaCl
c. CO2
d. H2O
Answer:
NaCl does not contain molecules
Explanation:
Molecules are made of multiple atoms bonded together to form a single entity.
In (H-H), two hydrogen atoms are bonded together through a covalent bond. Hence it is a molecule.
In (O=C=O), one carbon atom and two oxygen atoms are bonded together through double bond. Hence it is molecule
In (H-O-H), one oxygen atoms and two hydrogen atoms are bonded together through single bond. Hence it is a molecule.
In NaCl, ions are held together through ionic attraction forces. Here no actual bond exists between
. Both
remain present as individual ions.
Hence NaCl does not contain molecules
