<span>Oh ok, because producers make up the largest amount of biomass in most food chains, so they put it in the bottom of the pyramid, because the base of the pyramid is the largest part of it. </span>
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.
There is no difference between HEMoglobin and HAEMoglobin, except in spelling. Hemoglobin is the American version of spelling, whereas haemoglobin is the British one.
In the United Kingdom, many English words are spelled differently from its American versions, and haemoglobin is just one of them.
Hog feces contaminating groundwater near a farm is an example of a non-point source of water pollution
Answer: Option B
<u>Explanation:</u>
Non-point source of water pollution is caused by various distributed sources. This means that a pollution is caused in a different place but it is carried when water runs and contaminates other water supplies is called as non-point source. Non-point source is caused by rain, snow melt finally depositing into another water resource.
Hog feces may contaminate the groundwater near a farm but when rain comes it sweeps the excretion to a nearby water resource causing a major pollution in the water. Hog feces is environmentally hazardous causing wheezing, fatigue, depression and even cancer.
Answer: microscopes
Similarly the development of microscopes drove, somewhat later in the same century, the discovery of cells; Hooke and van Leuwenhoek, like Galileo, were hands-on developers of their instruments.The discovery of the green fluorescent protein (GFP), increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technical advances that have spurred on many areas of cell biology
