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.

Why do you use immersion oil with a 100X objective lens?

Answers

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 is CIPA?

CIPA is state known as congenital insensitivity to pain with anhidrosis is affecting the thermoreceptors and mechanoreceptors and thus make it unable to feel pain or temperature.

Receptors are structure able to capture signal from a stimuli and pass it to the brain from it carries a signal in return.

Mechanoreceptors are sensory receptors that transduce signals through ion channels which are mechanically gated.  These receptors reacts to touch, pressure, motion stretching etc.

Thermoreceptors realize the change in temperature in the body and external stimuli with heat. If these two kind of receptors are damaged a person will be  unable to feel pain or temperature.

Hence, a person with CIPA have affected with their  Mechanoreceptors and thermoreceptors. Thus, option B is correct.

Describe the 3 layers of the mantle

Answers

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.

4: Only people who truly knew her could tell when something was wrong

5: The star players leg was broken, so they had no chance of winning their game.

I hope this helps!

1.Melodramatic means to be overdramatic, this helps you understand the sentence more because it makes everything more clear on why she was crying and accusing her parents
2. a sharp pang of remorse basically stating that an intense hurt that had come on suddenly or in shorter terms a deep sadness and pain, this explains that Tom feels horrible because of how Rory is blaming him and punishing him and he is just starting to understand
3. Earnest is to show the results from showing or being sincere and in simpler words being focused on whatever your goal is, this shows that in the beginning Allen made jokes and seemed like a lighthearted kid who didn’t care about what was going on around him then one day he became more serious and started to care for his surroundings
4. Demeanor is how someone behaves and how someone presents themselves the sentence is saying that when something was off about the girl when you really knew her you could tell when something was wrong when she was upset or happy or depressed
5. Dismal means depressing or dreary, the team was sad, depressed, somber about the championship was no longer able to be won

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 -

Answers

2.) Fixed and movable pulleys can be combined.

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.

Answers

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.
