It is best to use regular light microscopes to observe that.
For simple structures, onion cells doesn't require a very large magnification. Magnifications for such as 100X or 150X is already enough to determine the different structures of onion cells such as cell walls or cytoplasm.
It is not very suitable to use a electron microscope especially as high school or college students, as electronic microscopes can be really expensive, usually only top universities have them. Also, it is quite complicated to control the microscope comparing to the common light microscope that we can easily find in many school laboratories. They're easy to function and they're a lot cheaper.
So, it's best advised to use a light microscope, unless if you're really into studying very detailed structures and you're experienced in doing these sorts of things, then you should use a electron microscope.
The right answer for the question that is being asked and shown above is that: "selective cutting" This type of harvesting leaves behind a diverse forest. The type of harvesting is called the <span>selective cutting.</span>
Answer:
The correct answer would be option A.
Explanation:
Gina's model lacks many important factors about the particular study of damage to tree bark in the forest. This model does not explain the number of animals entering a particular area of forest.
This model does not tell, how much damage has been done. It also fails to tell what type of damage the tree has faced. It does not explain what type of bacteria evolved or carried by the animal.
Thus, the correct answer would be option A.
I think the correct answer from the choices listed above is option A. The relationship between the themes of “place” and “human-environment interaction” is that the characteristics <span>of “place” include things like economic activity, architecture, and culture, all of which are human elements that alter or can be influenced by the environment. </span>
Answer:
See the answer below.
Explanation:
The arrival of cacao beans in the factory can be likened to the transcription of mRNA using a DNA template.
Sorting of the best beans at the factory can be likened to splicing process. During splicing, the introns are removed from the newly synthesized mRNA and the exons are joined together. The introns represent the non-coding portion of the mRNA while the exons represent the coding sequence.
The checking of bags by quality control can be likened to the final proofreading of the mRNA after splicing before being transported to the cytoplasm where they are used to synthesize proteins.
The large truck that transports the cacao beans represent the transport proteins that transport the mRNA to the cytoplasm while the chocolate-producing company represents the ribosome which is the site of protein synthesis.
