Answer:
There is a great difference between light and scanning electron microscope. The source of illumination is light rays in light microscope while in scanning electron microscope electrons are the source of illumination.
The resolving and magnification power of scanning electron microscope is much greater than that of a light microscope. The magnifying power of a light microscope is 1000X and of electron microscope is 10,00,000X.
In light microscope image is seen through the eyepiece while in scanning electron microscope it is seen on a fluorescent screen. Even small specimens up to 0.1 micrometers can be seen by scanning electron microscope which is not possible to see by light microscope.

Answer:
b. Genetically engineered trees could have unexpected interactions with organisms of natural ecosystems.
Explanation:
A genetically engineered tree has had it's dna undergo certain modifications through the use of genetic engineering techniques. Such trees are made to have faster growth rate, resistance to insects and diseases. Environmentalists are concerned about these trees and how they could affect the natural environment causing adverse effects to the natural organisms of the ecosystem.
Soil
Soil is the upper layer of the ground comprising of a mixture of sand, silt, clay, loose rock fragments, and organic matter that can support the growth of rooted plants. The relative proportions of sand, silt and clay determine the texture and size of the pores of the soil, which affects its ability to allow air and water to penetrate/infiltrate.
A student's post on photosynthesis can be reliable because he cited multiple high-quality studies from scientific journals.
When we research to show that a hypothesis or idea is true, we need to give it reliable support so that people who read our research trust the conclusions of our research, and it is considered as true knowledge.
To give reliable support to an investigation, it is necessary to resort to feasible arguments or true knowledge developed by researchers and specialists. For this, we must consult sources of reliable information.
Examples of reliable sources of information are:
- International scientific journals
- University research
- Proven scientific evidence
- Specialized books
According to the above, what the student must do so that his publication is reliable for other students is to cite reliable sources so that the knowledge he is sharing is reliable.
