Rosin is a chemical compound which is a gum that is added while making soaps. During saponification, it forms sodium rosinate which forms lathers.

When the soap is dissolved in a solution of ethanol while making it and then evaporating the excess ethanol not used in the process, a transparent soap is formed.

Sodium carbonate and trisodium phosphate acts a builders or building agents in powder soaps. These make the soap act more rapidly.

If the normal points in the opposite direction of the field, then θ = 180^o and the flux is taken as negative. If the magnetic field is pointing opposite the direction of the surface area then the value of this flux is negative.

Magnetic flux = B ΔS cos 90^o
Magnetic flux = 0.
It follows that magnetic flux linked with a surface is zero when the direction of the magnetic field is parallel to the surface area.

The magnetic flux is measured as the product of the component of the magnetic field normal to the surface and the surface area.
Magnetic flux is a scalar quantity.

The inheritance of characters by plasmagenes is known as extrachromosomal inheritance or extranuclear inheritance. Plasmagenes are some self-replicating genes which are present in the cytoplasm, mitochondrial DNA and chloroplast DNA.

Widow’s peak is an example of a dominant trait. Other dominant traits include tongue rollers, morphan syndrome, free ear lobes, etc. Some recessive traits are tongue non-roller’s, Duchenne muscular dystrophy, Lesch-Nyhan syndrome, fused ear lobes, Tay- Sachs disease, etc.

Blue eyes are the representation of a recessive trait. Some other recessive traits include albinism, alkaptonuria, and cystic fibrosis. Some dominant traits are achondroplasia, brown eyes, brachydactyly, Huntington disease, etc.

Females suffering from Turner’s syndrome do not have well-developed ovaries. Instead, they have rudimentary ovaries. Other characteristic features of this disease are short stature, poor breast development, and no menstruation.
