Nerve and muscle are the cells that no longer undergo mitosis.
A cell must go through either mitosis or meiosis in order to divide. Since neurons are somatic cells, they must go through mitosis. Centrioles must travel to the poles and generate spindle fibers that pull the chromosomes in order for mitosis to take place.
Neurons cannot undergo mitosis because they lack centrioles, which prevents them from dividing.
In our nervous system, each nerve cell has a unique location. Its sole responsibility is to transmit a signal from one place to another. In a particularly complicated system, adding more nerve cells might disrupt these extremely precise connections.
Therefore, Nerve and muscle are the cells that no longer undergo mitosis.

Answer: Ammonia belongs to Inorganic compounds.
Inorganic compounds are those compounds which do not have C-H bond ( Carbon- Hydrogen bond). The molecular formula of ammonia is . It is also called as Nitrogen hydride. Nitrogen is linked to three hydrogen by the covalent bond. It exists in the gaseous form in its pure state.
Since there is no C-H bond in its molecular formula, therefore it belongs to inorganic compounds.
Answer:
B is the closest.
Explanation:
Its a direct and obvious lean toward lake and forest
Answer:
B lake for animal and bird for forest.
B) repetition.
C) replication.
D) validity.
Answer: C) replication.
Explanation:
Replication in experiments is the process by which the entire experimental process is repeated as done by the previous scientists, keeping in mind all the necessary requirements and experimental conditions so as to determine the correctness of the experimental methodology, relationship between the variables, correctness of the results and other parameters.
Here, several group of students are repeating the same experiment and getting the same results this process is called as replication.
B.All cells that currently exist have originated from pre-existing cells.
C.Cells are the most basic structural and functional unit of life.
D.All cells possess DNA enclosed within a nucleus.
