The agar surface of a laboratory dish covers the entire area of the dish. An inadequate spread of inoculate will not give the desired outcome.

Why are colonies that develop on a heavily seeded plate smaller than those that appear on a sparsely seeded plate?
Heavy seeded plates means a agar plate having inoculum in large quantity it is generally done by spreading method with low dilution or concentrated inoculum and is done for the need of large no. of colonies generally in industrial purpose. Sparsely or low seeded plate are those which contain very diluted spreaded inoculum or little streaking inoculum it is generally done for examine and study purpose for understanding the physiology and morphology of microbe.
What is lawn culture of bacteria?
A lawn culture is a type of culturing used in to test the sensitivity of a microorganism. One should spread the active culture evenly across the surface either by covering the surface of the agar with the culture then pouring off the access or by taking a culturing rod and spreading the culture evenly across the surface of the agar, sort of like spreading peanut butter over a piece of toast.
Why is condensation on the agar undesirable?
It'll cause the spreading of the colonies that are growing on the agar surface if the condensed water falls on them. That's why usually the plates are inverted during incubation.
What are the other inoculating instruments aside from needle?
Aside from the inoculating needle, an inoculation loop, is a simple tool used mainly by microbiologists to retrieve an inoculum from a culture of microorganisms. Its tip is a wire made of platinum or nichrome, the latter being inferior but less expensive. The wire forms a small loop with a diameter of about 5 mm. This loop is handy for taking an inoculum from a liquid by using the phenomenon of surface tension. It is also called a smear loop, inoculation wand or microstreaker, The loop is used to cultivate microbes in Agar jelly and to use the streak maneuver to transfer microbes. The inoculation loop is always sterilized in a flame until it becomes red hot before and after each use. By doing this, the same tool can be reused in different experiments without fear of cross-contamination. After flame sterilization, the loop must be cooled so that the next cells to touch the loop don't instantly die.
Does a tree have a taproot system?
fibrous root Neem trees are generally raised from seeds hence there is tap root coming out of radicle of the embryo.
A consequence of the surface tension of water is what?
capillary action is a common consequence of surface tension.
A consequence of the surface tension of water is?
The surface tension of water is responsible for the cohesive properties it exhibits. For example, capillary action is a consequence of surface tension.

What is surface area and how you can decrease or increase surface area?
You can increase surface area by spreading the object
Why loop and cap should not be laid on workbench while transferring inoculum?
To prevent contamination. Once you have flamed your loop and cap, do not lay it down, blow on it, touch it with your fingers, or touch it to any surface other than your inoculum or the sterile media.If you do, you must reflame the loop before proceed to inoculation to re-sterile it again.
What is the definition of spreading?
Distributing over a surface in a layer:
What are the surface effect at a divergent boundry?
sea floor spreading and landslides
What evidence do you see that beach erosion has occurred?
Reducing the surface of the beach is a consequence of erosion.
What happens to spreading boundaries?
SPREADING ZONES Spreading zone occurs in the border of two tectonic plates. This happens when the plates generally move away from each other creating an opening for the magma to force through the surface.
What happens at spreading plate boundaries?
tectonic plates move apart allowing magma to move to the surface.
How does a bike helmet protect your head?
By absorbing some of the impact energy and spreading some of it over a larger surface.
What keeps the particles of a liquid from spreading out to fill an entire container in the same way that gas particles do?
Surface tension.
