Q.6 How can you change ansaturated solution to asaturated solution?
Answers
Explanation:
1)Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell's cytoplasm or embedded within the endoplasmic reticulum.
2)The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.
3)Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
4)a) Candida auris.
b)Enterobius vermicularis Pinworm
5)Separating funnel is used to separate the mixture of two immiscible liquids. Kerosene oil and water do not mix with each other and form two separate layers. The mixture separates into two layers according to their densities.
6)A saturated solution is that which is dissolved as much solute as it is capable of dissolving. By heating the solution a saturated solution can be changed into an unsaturated solution. Without adding any solvent it can be changed into an unsaturated solution.
