Answer and Explanation:
Principal of Spiral plating:In the spiral plate technique, a mechanical plater vaccinates the fluid sample on a pivoting plate agar. The volume of fluid sample decline from the inside to the edge of the plate. The microbial concentration is controlled by checking the provinces on a piece of the Petri dish.
A technique, portrayed for deciding the quantity of microorganisms in an solution by the utilization of a machine which stores a known volume of test on a pivoting agar plate in a consistently diminishing sum as an Archimedes spiral.
Materials used: agar plates, dilution blanks, pipettes
Method:
A spiral plater is a gadget that disperses a constantly diminishing volume of fluid over a solitary pivoting agar plate (the apportioning arm moves like a needle on a turntable, just in reverse). The agar is then hatched and checks are made. It can viably convey up to a 105 concentration range on one plate, yet list requires an uncommon tallying lattice. After the example is brooded, distinctive state densities are clear on the outside of the plate. A changed checking matrix is portrayed which relates zone of the plate of volume of test. By checking a proper territory of the plate, the quantity of microscopic organisms in the example is assessed.
Option 1
that can give nice mixtures of colors in flowers, like alleles for white and red are expressed, and mixed to pink seen by the human eye
Between every food chain from one animal to another there is 90% energy loss so if a herbivore eats a plant, it will only get 10 joules of energy. and if a carnivore eats the herbivore then it will only get 1 joules of energy. so in every food eaten, there is 90% energy loss.
Explanation:
transmission of inner ear 2 determine pitch = 3 bones called OSSICLES.
11) malicious hammer
2) Incus
3) The stapes.
these 3 bones form a bridge from tympanic membrane 2 oval window.
sound travels thru oval window, enters cochlea in inner ear..
