Nuclear fusion differs from nuclear fission because nuclear fusion reactions. Nuclear fusion forms heavier isotopes from lighter isotopes. Nuclear fission forms lighter isotopes from heavier isotopes. therefore, the correct options are option 1,2.
Nuclear fission gets a nuclear process in which the atom's nucleus is divided into smaller nuclei by being blasted with low-energy neutrons. In this process, a large quantity of energy is released. Nuclear fission processes are employed for nuclear power reactors due to their simplicity and high energy output. When multiple atoms unite to produce one heavier nucleus, the process is known as nuclear fusion. In comparison to the energy produced throughout the nuclear fission reaction, a tremendous quantity of energy is released during this process.

The answer is: the type of bonding among the particles.
For example, calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).
Because it has strong ionic bonds, it has high melting point (around 2600°C).
Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).
Amount of energy required to change 1 gram of material from the solid to the liquid state at its melting point
Red blood cells are primarily formed in the bone marrow, specifically the red bone marrow. The process of producing these cells, known as hematopoiesis, begins at the embryonic stage and continues throughout a person's life, with adult hematopoiesis being largely restricted to certain bones in the body. New red blood cells are continuously produced due to their relatively short lifespan.
Red blood cells are formed in the bone marrow, specifically in the red bone marrow which is a loose collection of cells where hematopoiesis or the production of blood cells occurs. This crucial process of forming blood cells, including red blood cells, is introduced in the embryonic stage in the yolk sac. However, as the embryo develops, this function is taken over by the spleen, liver, and lymph nodes, with the bone marrow eventually assuming most hematopoietic functions. The red blood cells, along with white blood cells and platelets, are all produced in the red bone marrow.
In children, this process can occur in the cavity of long bones, but in adults, it is largely restricted to certain bones such as the cranial and pelvic bones, the vertebrae, the sternum, and parts of the femur and humerus. The lifespan of these cells is relatively brief, so new ones must be continuously produced to maintain healthy bodily functions.

Answer:
False, they are non-effective
Explanation:
Answer: ethylene glycol (molar mass = 62.07 g/mol)
Explanation:
Depression in freezing point :
Formula used for lowering in freezing point is,
or,
where,
= change in freezing point
= freezing point constant=
m = molality
Given mass of solute = 0.807 g
Molar mass of solute=? g/mol
weight of solvent in kg= 11.6 g=0.0116 kg
Thus the solute is ethylene glycol which has same molecular mass as calculated, i.e 62.07 g/mol.
