Chain reaction
Nuclear energy
Explanation:
Question 1:
Chain reaction:
A reaction in which when one occurs, it starts a series of other fission reaction is called a chain reaction.
Most nuclear reactions are chain reactions in which does not come to rest in one step like chemical reaction.
In nuclear reactions like which fusion and fission, one step leads to another until an atom attains stability or a stable product is formed.
The energy needed to sustain the chain process is produced in the previous reaction.
Nuclear energy:
The type of energy used in a nuclear power plant is called a nuclear energy. Nuclear energy is used to generate power in nuclear plant.
During a nuclear decay process, a huge amount of energy is released. This energy is channeled into electricity production and to do other useful works.
Nuclear energy is classified as a non-renewable source of energy.

The right answer is 4).
The cytoskeleton is made up of biological polymers of proteins, sometimes called fibers because of their large size at the cellular level. They are classified into three categories:
Microfilaments: involves in cytoplasmic phenomena (division, endocytosis, migration).
Intermediate filaments: Maintenance of the nucleus structure.
Microtubules: Involved in the separation of chromosomes during mitosis.
Answer:
D) or A) dont know
Explanation:
Because in 2006 it was no longer considered a planet because it did not meet it did not meet the three criteria the IAU uses to define a full-sized planet.
I hoped this helped you out! in figuring out the answer :)
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features)
