Answer:
Measurement (Count) of Cell Numbers:
1. Breed Method:
A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.
Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.
Atoms in molecules share pairs of electrons when they make ionic bonds.

Answer:
The living organism is the organism that responds to external stimulus, moves, grows, respire, reproduce, eat and excrete.
Movement - An organism moving from place to place.
Respiration - The release of energy from glucose, occurring in every cell. we respire in order to produce energy
Sensitivity - the ability to detect and respond to stimuli. When we touch something hot, we remove our hand suddenly.
Growth - The production of new cells in an organism.
Reproduction - The process which is used to create offspring similar to parents.
Excretion - The release of harmful substances from the body. We excrete carbon dioxide when we exhale.
Nutrition - Consumption of food for energy. We get nutrition by eating three meals a day.
