What term is defined as the ability to do work

Answers

Good Morning! In the understanding of biological sciences in general, the ability to perform work, that is, to effect movements, pratices or even functions without macro representation, for a result, is called "energy", and can have different sources, forms and origins. Thus, it is possible to affirm that: energy is the ability to do work. Hope this helps. Let me know if you need additional help!

In Physics, the term that represents the ability to do work is energy.

Physics defines the term you're referring to as energy. Energy is the ability to do work. It is the capacity of a system to perform work or to transfer heat as a result of motion or position.

How passage of food from the stomach is regulated onwards?

Answers

the pyloric sphincter controls the passage of food(chyme) from the stomach into the small intestine. The movement of food (chyme) through the small intestine and large intestine is controlled by paralysis. The iliocecal valve is a sphincter muscle that is normally contracted to prevent the contents of the colon from moving back into the ileum (last portion of the small intestine). The anal sphincter controls the movement food (feces) from the rectum to outside the body.

A ______ frequency causes a _____wavelength and ______ energy. Lesson: 4.09 Question 10 options: higher, shorter, high low, shorter, greater low, greater, shorter higher, greater, shorter

Answers

Answer:

A higher frequency causes a shorter wavelength and higher energy.

A shorter frequency causes a greater wavelength and low energy.

Explanation:

Frequency is the number of waves that move at a period of time. It is measured by counting the number of crest point.

Wavelength is the distance between waves. A wave with higher frequency have crest that a very close and therefore the distance between them or wavelength is short compare to a wave with low frequency that the distance are farther apart and they have long wavelength. Therefore to generate high frequency of wave , more energy is required to do this .

You have a chart that illustrates a series of species with their common ancestor. This chart is a A. gene pool.
B. fossil record.
C. cladogram.
D. five-kingdom system.

Answers

The answer is C. Cladogram

The terms come from "clade" which refer to a group of individuals and their common ancestors

On the largest scale of cladogram, all living organism could be considered coming from the some ancestor. Because in the beginning of the world, before the mutation happened, we all come from a single cell organism

How does the motion of particles in a gas change as the gas cools?They move more slowly.

They move in a more circular pattern.

They move faster.

They move more randomly.

Answers

A they move more slowly
yes the answer would be (A) its back to the basics guys and if you dont get the question, here let me help basically think about this logically if you heat up a cube of ice whats it going to do freeze? obviously not its going to melt so the same thing applies vice versa if water is cooled will it melt? no its going to freeze when heat is applied to something the molecules tend to vibrate and sometimes sense molecules in solid are very close together when heat is applied those molecules start to move and sometimes if heated enough the molecules will start moving in a weird pattern and go passed each other by then it would have probably been a liquid now as for gases their molecules are incredibly spread apart they are going everywhere they are flying passed each other  so think about the basics when something is heated its molecule vibrate fast when something is cooled its molecules movement slow down so just think about that little sentence I just said and apply it to gasses when gas is cooled its molecules will slow down due to the temperature sorry this was so long I just wanted you guys to understand this because you need to know this so you can understand everything else see ya!
