smooth
The harmless bacteria likely produced colonies with well-defined edges due to their growth pattern on the agar medium. Bacterial colonies can exhibit different features based on factors such as their species, growth conditions, and nutrient availability in the environment. The distinct edges could be a result of the bacteria's growth slowing down or becoming restricted at the periphery of the colony.
The disease-causing strain of bacteria grew into smooth colonies on culture plates, whereas the harmless strain produced with rough edges.
Some Biology books may say something different but mine is Prentice Hall Biology and its page 287. The answer to this would be smooth colonies. :) so if your ever looking for this answer hope it works for you!
Stationary transverse waves are produced on strings. This is due to the superimposition of the progressive wave and its reflection at the knife edges.
In the Falkland Islands, Europe. Their nests are built on Cliff Edges, or on the Outskirts of Penguin Colonies.
I dont think how far my answer is correct but, the amplitude of the sound produced at the centre of the drum is more when compared to its edges. this might be due to the tension in the leather surface of the drum and the law of vibrations.ie, towards the centre where at a particular point when moving away from the edges of the drum vibrates more than at edges. Here, the force of the stick( if a stick is used) with which the sound is produced must also be taken into consideration and also the make of the material with which the sound is being produced.
angle between two edges and angle of incidence how denser the object is
It sure can. It will be flat, grayish, with spreading edges.
It is important to be able to identify different colony shapes, sizes, and edges is a way to learn and identify the name of the bacteria. A selective medium is a nutritional for bacteria to grow while inhibiting other bacteria growth.
Also known as paronychia, this refers to the infection or inflammation around the edges of the nail, often caused by bacteria or fungi.
You should hold a microscope slide by the edges to avoid smudging or getting fingerprints on the glass surface. This helps ensure a clear and unobstructed view when examining the slide under a microscope.
Microorganisms such as thermophiles, algae, and bacteria are known to inhabit geysers due to their ability to thrive in extreme heat and acidic conditions. These organisms form colorful mats or biofilms around the edges of geyser pools.
