Answer: True, both of the given statements are true.
Explanation:
1. Nearly all the environment contains microorganism whether it is soil, air, water or any other surface. They have the ability of live in the extreme conditions.
There are different forms of bacteria found at different places. Some of them are thermophiles that at found in extremely hot conditions such as thermal vents.
The organism like Psychrophiles are the microorganisms that have the ability to survive at lower temperatures. Example: bacteria found in polar regions.
2. A culture can be defined as a pure culture if it has an unadulterated species of bacteria. It has no contamination and if a small inoculum from the pure sample is streaked on a plate then a pure culture of the sample is obtained.
This should be done in an aseptic condition so that the bacterial species should be free from contamination.
Codominance would make the cross' coat a color in between red and white. Hope this helps.
B)landform 2 is what was made by the deposition of sediments
Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
