Describe the details you were able to see when viewing specimens with scanning electron microscope

Answers

Answer:

The scanning electron microscope allows the elaboration of an image in which the surface characteristics of the sample are reflected, thus providing sufficient information on the shapes, textures, and chemical composition of the constituents.

Explanation:

The scanning electron microscope uses electrons instead of light for imaging.

To achieve this, the team has a device that produces an electron beam that allows the entire sample to be illuminated and, through different detectors, the electrons that are produced from the interaction with the surface of the sample are later collected.

The scanning electro microscopesallows you to view three dimensional picture of the sample.You could see all the different outer structures on the base of each sample

What radiation is used in hospitals and how does it cause a problem for staff/workers?

Answers

Radiation is used for X-rays, MRIS, any type of cancer killing.
Too much of radiation can be a dangerous thing... you could end up dying from a lot of exposure.

The radiation used is gamma radiation. It causes a problem for staff/workers as it's highly penetrating meaning it can penetrate (go through) almost anything . The staff/workers will have a lot of exposure to this gamma radiation and too much exposure allows the radiation to kill cells, even the useful ones.

Which plant adaptation would likely be found in the taiga?

Answers

Taiga is a coniferous forest in the northern high latitude with subarctic climate. Summers are short with low temperatures, and winters are very long and cold. Many trees are evergreen conifers with needle-like leaves. These characteristics help photosynthesis (evergreen) and at the same time less water loss (needle-like leaves). Also, leaves are dark-colored to absorb more solar heat.

The Northern Hemisphere is warmer in spring than in winter, because in springA) the days are shorter.
B) it gets more direct sunlight.
C) the Earth is closer to the Sun.
D) it is tilted away from the Sun.

Answers

Answer:

Option (B)

Explanation:

When the tilt of the earth is towards the sun, then it is called summer in the northern hemisphere. In this position, the sunlight is directly over the earth, as a result of which it absorbs more amount of heat. Spring is the season that starts from about 21st March to 21st of June or it can be considered as the season that exists between the summer and winter. Here, a high amount of sunlight is absorbed due to which the temperature eventually rises.

This is the reason why the northern hemisphere is relatively warmer during the spring season than in winter.

Hence, the correct answer is option (B).

B. It gets more direct sunlight.
