How could you identify a potential contaminant on a streak plate?

To clean a streak plate I use coke classic. In the red can, the diet version does not work as well. I believe it is the acid that takes away the powdered rock debris. It makes them quite white again. Mr clean magic eraser also takes away some of the heavy debris...but does not get them clean enough.

∙ 14y agoIn the streak plate technique, a loop is used to streak the mixed sample many times over the surface of a solid culture medium in a Petri dish plate. Theoretically, the process of streaking the loop repeatedly over the agar surface causes the bacteria to fall off the loop one by one and ultimately to be distributed over the agar surface, where each cell develops into a colony

∙ 15y agoA contaminant is anything other than the organism(s) you were trying to grow. This question is a little like asking what plants are weeds and there is no 100% true answer. The purpose of a streak plate is to gain single isolated colonies. The most troublesome species to find growing on your streak plates are swarming bacteria as they spread and contaminate other colonies, pseudomonas sp. are an example. The contaminating bacteria could have come from the operative or from the room where the procedure was carried out.

See the Related Question for more ways the spread plate can become contaminated.

Does corn have kinetic energy?
No, corn could be said to have potential energy due to it's position or constituents.
What will happen to a person's resting membrane potential if they take potassium enhanced intravenous solution?
A potassium enhanced intravenous solution would increase the concentration of potassium ions in the brain. Since potassium ions are positively charged, they depolarize the resting membrane potential. For example, a resting membrane potential of -65 millivolts would be depolarized to -62 millivolts. An appropriate concentration could lead to a significant depolarization of, say, -60 millivolts, at which point an action potential could be possible.
Which phase of the cell cycle could you identify most readily with a light microscope Explain your answer?

Could a pH sensitive color indicator be used to reveal the presence of a contaminant in a fluid?
yes
Why could the streak of corundum be difficult to determine?
The mineral corundum, with a Mohs hardness of 9, will be harder than a ceramic streak plate and therefore leave no streak.
Will diamond leave a streak on a streak plate?
Diamond will not leave a streak on a porcelain streak plate because diamond is harder than the streak plate. It will leave a scratch on the streak plate for the same reason.
What is used to find the streak of a mineral?
The streak of a mineral refers to the color left on a streak plate after rubbing a mineral across its surface. A streak plate can be as simple as the unglazed side of a porcelain tile. The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of the unglazed porcelain streak plate. The streak color may differ from the color observed in a specimen. The streak is used as an aid in the identification of minerals.
What is the importance of reviewing your own training and development?
Reviewing your own performance - can identify weak spots which could be rectified by on-the-job training. It can also show your strengths - and potential for promotion.
Could a ph-sensitive color indicator be ussed to reveal the presence of a contaminant in a fluid that should be sterile?
by white to violet
What is the streak of sandstone and the hardness?
Streak and Mohs hardness are descriptive and identifying terms for minerals. Because sandstone could be composed of a multitude of different rock particles or minerals, a specific hardness or streak cannot be attributed to them.
Did undertakers streak end?
No Undertaker's streak did not end (sadly i wanted hbk to end it). If you watch the latest wrestlemania wich is wrestlemania 27 Triple H could not end the 19-0 streak(sadly).
Explain how you could promote inclusion equality and diversity with your currentfuture learners Identify other points of referral available to meet the potential needs of learners?
To promote inclusion, equality, and diversity with my learners, I would incorporate diverse perspectives in teaching materials, create a safe and respectful classroom environment, and encourage open discussions on these topics. Other points of referral to meet learners' needs could include counseling services, specialized support groups, or external organizations focused on diversity and inclusion. Additionally, providing access to resources like mentorship programs or relevant workshops can support learners in engaging with these important principles.
What is a group of tiger called?
