What kind of light is used to excite dyes and make microorganisms fluoresce?
Ultraviolet light is commonly used to excite dyes and make microorganisms fluoresce in techniques such as fluorescence microscopy and flow cytometry. The dyes absorb the UV light and emit light of a longer wavelength, allowing for visualization and analysis of the samples.
What is a device that helps make work easier by changing the size or direction of force?
A device that helps make work easier by changing the size or direction of force is a machine. A simple machine has only one movement. A wedge has a moving inclined plane. A inclined plane has a sloped surface.
If you strongly suspect a nutrient agar slant culture is contaminated what method would you use to ascertain whether you are right or not?
You have to make subculture from this slant and after incubation you can observe how many types of microorganisms are present in the nutrient agar slant. If you have one colony shape so you have a pure nutrient agar slant but if you have more than one type of colonies so the nutrient agar slant is contaminated.
What kind of micro-organism can make us ill?
In general, microorganisms that can make you sick are termed "germs" by the non-medical world. Bacteria that can cause disease or sickness are termed "pathogens." There are way too many to list here and certain strains of microorganisms can be harmful while other strains of that same organism may not be.
How does technology like the microscope aid biologists in learning about the natural world?
Microscopes allow biologists to magnify and observe tiny biological structures such as cells, tissues, and microorganisms. This enables them to study the details of biological processes and structures that are not visible to the naked eye. By using microscopes, biologists can make important discoveries and gain a better understanding of the natural world at a microscopic level.
What is the use of scientific tools to make things easier and better?
"Applied science"
Can you make work easier physics?
In physics, work is defined as the force applied to an object over a distance. To make work easier, you can either increase the force applied or shorten the distance over which the force is applied. Using tools or machines can also help by amplifying the force applied or making it more efficient.
Describe what you observe in the small intestine?
Some what bumpy, probably to make things go through easier.
What is a string of text applied to a row or column to make data easier to understand?
comment
One way a machine can make work easier for you is by?
by changing the direction of the force you applied
What is the use of scientific tools to help make things better and easier?
"Applied science"
Who was the second man to make a microscope?
The second man to make a microscope was Antonie van Leeuwenhoek, a Dutch tradesman and scientist. He made significant advancements in microscope design and was the first to observe and describe microorganisms.
What was an advantage of having fire for cooked food in paleolithic?
It makes food taste better, easier to digest, and can make food safer to eat by killing harmful microorganisms.
How can I soften wood glue to make it easier to work with?
To soften wood glue and make it easier to work with, you can use heat or moisture. Heat can be applied using a heat gun or hairdryer, while moisture can be applied by using a damp cloth or sponge. Be cautious not to overheat the glue or add too much moisture, as this can affect the bonding strength.
One way a machine can make work easier is by?
reducing the amount of physical effort required by amplifying or transferring the force applied by a person.
What kinds of devices make work easier by reducing required effort or by changing the direction of required effort?
Levers multiply the mechanical force that can be applied to another object, thus making work easier.
What harm do we get from microorganisms?
Some microorganisms make us sick, but others keep us healthy.
