Answer: The correct answer is -
interphase and M phase.
Explanation:
Cell cycle can be described as a series of events that take place for the division of cell into two daughter cells.
It is primarily divided into two stages, which are-
1) Interphase (that is further divided into G1, S, and G2 phase) that involves the duplication of DNA and other proteins required in cell division.
2) M (mitotic phase) phase during which the nuclear division takes place through four successive stages that are prophase, followed by metaphase, anaphase and telophase.
After this cytokinesis (cytoplasmic division) occurs resulting in formation of two daughter cells.
Thus, first option is the right answer.
A conductor allows heat to flow easily, while an insulator resists heat flow. In general, metals are good conductors of heat and electricity.
A substance or material that permits the flow of electricity is known as an electrical conductor. When voltage is provided, electrical charge carriers, often electrons or ions, travel effortlessly from atom to atom in a conductor.
There are four different kinds of conductors: semiconductors, resistors, excellent conductors, and non-conductors.
Aluminum, gold, copper, brass, steel, and steel are all effective conductors of electricity. In the form of wires, we employ them in electrical circuits and systems. A great liquid conductor is a mercury. As a result, this material is used in numerous instruments. Thus, metals are good conductors.

Answer:
(C).Rough endoplasmic reticulum
Explanation:
Endoplasmic reticulum (ER) is a membrane-bound cell organelle, present in eukaryotic cells. There are two types of endoplasmic reticulum, smooth ER and rough ER.
Rough ER contains ribosomes on its outer surface (side, which is in contact with cell cytosol), while in smooth ER surface, ribosomes are absent. This is because ribosomes provide platform for the process of protein synthesis or translation.
Proteins synthesized by ribosomes present in rough ER surface are then transported to it (rough ER) for sorting and post-transnational modifications.
Thus, the correct answer is option (C).
Answer:
atomic number
Explanation:
The number of protons in an atom determines its atomic number, which is a defining trait of an element. In a neutral atom, the same number of protons also equals the number of electrons. However, the mass number or atomic mass is the total number of protons and neutrons.
The number of protons in the nucleus of an atom determines its atomic number. This is a defining trait of an element and determines its identity. For instance, any atom with six protons is the element carbon, which has an atomic number of 6 - this applies irrespective of the number of neutrons or electrons present.
Moreover, in a neutral atom, there must be an equal number of positive and negative charges implying that the number of protons is equal to the number of electrons. Thus, the atomic number indicates not only the number of protons but also the number of electrons in an atom.
The atomic mass or mass number of an atom, on the other hand, is the total number of protons and neutrons in an atom. Therefore, you can derive the number of neutrons by finding the difference between the mass number and the atomic number: (A - Z = number of neutrons).
