Dylan wants to observe some onion cells with a microscope. He places the cells on a slide. Describe how Dylan uses the microscope so he can see the cells with a ×20 objective lens.

Answers

Answer:

See the answer below

Explanation:

After routinely cleaning the microscope and ensuring that all the parts are working fine, Dylan would have to place the slide on the stage of the microscope, switch on the light source, and adjust the diaphragm of the condenser to ensure that adequate light gets to the slide on the stage.

Thereafter, Dylan would need to turn the revolving nosepiece in order to shift to the lowest objective of the microscope assuming it is not already in place. Then, the slide on the stage is brought into focus (by viewing through the eyepiece/ocular) by using the coarse/fine adjustment knob to bring the stage up/down.

Once the slide is brought into clear focus, the revolving nosepiece is then turned to switch the x20 objective. Generally, at higher objectives, the coarse adjustment knob is rarely needed and the fine adjustment knob is solely used instead to bring the slide back into focus. Thus, Dylan can see the cells of the onion at the desired objective.

Fall and Spring Equinoxes occur when days and nights are equal in length.

Summer solstice occurs when the Earth's North Pole is tilted toward the sun.

Winter solstice occurs when the Earth's North Pole is tilted away from the sun.

The tilt and revolution of the Earth causes the seasons

Answers

answer: Summer solstice occurs when the earth NORTH POLE is tilted in longest day.

Winter solstice occurs when the earth North pole is tilted shortest day

Explanation: took the test got an A

According to the Northern Hemisphere, all the statements given are exactly true.

What is the Northern hemisphere?

It is one-half of the earth that is located in the north of the equator. It has about 90 percent of the world's population and most of the world's land.

Equinox means the duration of day and night are equal in length. There are two equinoxes in a year when the sun moves across the celestial equator, which lies directly above the earth's equator. The summer solstice occurs when the earth's pole is tilted towards the sun and receives more sunlight in the northern hemisphere. Winter solstice occurs when the earth's north pole is tilted away from the sun and receives less sunlight. Overall, the tilting and revolution of the earth is the main reason for the causation of different seasons.

Therefore, all the given statements are true with respect to the northern hemisphere.

What is scaling?
Removing bark from a tree
Cutting down trees for timber
Measuring wood for harvesting timber
A survey of the number of trees in a forest

Answers

Answer:

measuring wood

Explanation:

for harvesting timber

Scaling is a survey of the number of trees in a forest. Therefore, option (D) is correct.

What is scaling?

Scaling is a method of estimating the amount of wood in a tree or in a stand of trees by measuring the diameter and height of the trees. This information is used to calculate the volume of wood in the tree, which can then be used to determine the amount of timber that can be harvested from the tree or stand.

Scaling is an important part of the forestry industry, as it helps to ensure that the timber harvest is sustainable and that the forest is managed in a responsible manner. Scaling does not involve cutting down trees or removing bark from a tree.

The amount of Cytosine plus Guanine is 40%. What would be the amount of Adenine?

Answers

Answer:

30%

Explanation:

Considering that the amount of Cytosine added to the amount of Guanine is 40%, that explains that Cytosine and Guanine each equal to 20%.

Cytosine: 20%Guanine: 20%

Now, the remaining bit is 60%. Since Adenine and Thymine both equal the same, that would mean: 60/2 = 30.

Adenine: 30%Thymine: 30%

Cytosine and Guanine pair together and will always be equal to one another. The same goes for Adenine and Thymine. (A=T, C=G)

Always remember that you want it to total up to 100% at the end.
