Answer:
They also occur in leaves and fruits and constitute the hard shell of nuts and the outer hard coat of many seeds. Sometimes known as stone cells, sclereids are also responsible for the gritty texture of pears and guavas
Explanation:
Correct Answer: Ratio
Determining a person’s reaction time would involve measurement on a
ratio scale that is expressed in milliseconds. It is a point where none of the quality being measured
exists and its scale has an absolute zero. In ratio scale, it allows comparisons
such as being twice as high or one-half as much. Additionally, in the case of a
person’s reaction time, it can be state that a response of 25 milliseconds is
twice as fast as a response time of 50 milliseconds.
I would say a hope it’s right
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.
