Describe the 3 layers of the mantle
Answer:
The 3 main layers are the core, mantle and crust
Explanation:
Answer:
I hope this is the answer for your question
Explanation:
Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt.
The mantle is located directly under the Sima. The mantle consists of very hot and dense rock. This layer of rock flows like asphalt under heavy weight. This flow is because of the greatest temperature differences from the bottom to the top of the mantle. The reason behind the plates of the Earth move is the movement of the mantle. Its temperature varies between 1600 oF at the upper part to 4000 oF near the bottom.

Why do you use immersion oil with a 100X objective lens?
Answer:
For example, by placing a substance such as immersion oil with a refractive index that is equal to the glass slide in the space filled with air, more light is directed through the objective and a clearer image is observed
Explanation:
Hope you have a great day :)
The 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens)
What is Immersion oil?Oil immersion is a technique used to increase the resolving power of a microscope by immersing both the objective lens and the specimen in a transparent oil of high refractive index, resulting in an increase in the numerical aperture of the objective lens.
An immersion oil used in microscopy essentially consists of a solution of hydrogenated terphenyl, a polybutene, and a mineral oil, which provides a solution with a refractive index between 1.5100 and 1.5240.
It is used for the highest power objectives because light refraction from low power magnification microscope objective lenses such as (10X and 40X) is negligible and not noticeable.
Thus, the 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens).

What two gases in the atmosphere do animals and plants need to breathe and grow?
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.
The equation for photosynthesis is 6H2O (water) + 6CO2 (carbon dioxide) + Light Energy → C6H12O6 (glucose) + 6O2 (oxygen). When first discovered, scientists were trying to decide if the oxygen in the product came from carbon dioxide or water. Which statement describes how scientists traced the path of oxygen?

which statement about pulleys is NOT true?
1. Fixed pulleys change the direction of output force.
2. fixed and movable pulleys can be combined
3. fixed pulleys increase the output force.
4. movable pulleys reduce the input force
- Will give Brainly for CORRECT answer -
Base on the fact below, it is therefore not true that movable pulleys reduce the input force.
Fixed pulley is positioned in a specific position which cannot be changed through out its application except it is uninstalled and installed in another fixed position. The magnitude of the force applied at one end will be the same at the other side. And it changes the direction of the output force.
Fixed and movable pulleys: One, two or more movable pulleys can be attached to a fixed pulley in order to increase efficiency or to achieve a certain goal.
Movable pulleys are the opposite of fixed pulleys. Movable pulley, as its name implies, can move from one position to another but it does not change the direction of the force applied. The force applied at one side of the pulley multiplies at the other side for the lifting of the load.
Base on the fact above, it is therefore not true that movable pulleys reduce the input force.

What is the most likely reason for the high temperature in the regions indicated in dark red? two maps of Atlanta, one showing an overhead view of Atlanta's buildings and structures and other showing the heat levels in the area Atlanta’s roads and buildings absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. Atlanta’s trees and forests absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. The rural areas around Atlanta absorb more heat than the urban areas, causing an overall increase in the city’s temperatures.

A. If the frequency remains constant, the wavelength size increases.
B. As the wavelength size decreases, the frequency decreases.
C. As the frequency increases, the wavelength size decreases.
D. If the wavelength remains constant, the frequency increases.
Answer:
b makes the most sense
Explanation:
Answer:
I think C is the correct answer.
Explanation:
The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Name and describe three measures of central tendency used to summarize data.
Read the assignment carefully and make sure you answer each part of the question or questions.
After you've written your response, go back and read it again to make sure your thoughts are clear.
Answer:
Explanation:
You can think of it as the tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.
There are three main measures of central tendency: the mode(the number that occurs most often) the median ( the middle value in the list of numbers) and the mean (the average number in the list of numbers).
Answer:
The mean, median, and mode are three of the most commonly used measures of central tendency.
Explanation:
Quantitative variables are often summarized using numbers to communicate their central tendency. The numerical average; calculated as the sum of all of the data values divided by the number of values.

What process brings Carbon into the biotic part of an ecosystem?
Answer:
Carbon moves from plants to animals.
Explanation:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
