Support and protect the body is NOT a function of the digestive system

Your body's skeletal structure serves as a support system. It gives the body its structure, permits mobility, produces blood cells, offers organs protection, and stores minerals. A different name for the skeletal system is the musculoskeletal system.

<h3>What is digestive system ?</h3>

The digestive system consists of organs that are crucial for breaking down both food and water. These include the anus, pharynx (throat), stomach, small and large intestines, rectum, and oesophagus.

The body needs nutrients for energy, growth, and cell repair, and nutrients are broken down into via the digestive process. Prior to the blood absorbing nutrients from food and drink and transporting them to body cells, those nutrients must be broken down into smaller molecules.

What is the amount of charge a capacitor can store per volt of potential difference?

sladkih [1.3K]

The amount of charge a capacitor can store per volt of potential difference is called the capacitance of the capacitor.

<h3>What is the capacitance?</h3>

The capacitance has to do with the amount of charge that is stored by a capacitor. We know that a capacitor is a device that can be used to store electric charges. We have in it, two capacitors separated by a dielectric material.

Hence, the amount of charge a capacitor can store per volt of potential difference is called the capacitance of the capacitor.

In a wave, what do you call the difference from crest to crest or trough to trough

UNO [17]

The correct answer is "wavelength".

In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is
D) wavelength.

Indicar objetosque puedan ser observados a simple vista, con microscopio, con microscopio electrico y con miscroscopio de transm

AysviL [449]

Answer:

En esta respuesta voy a usar la unidad μm, tal que:

1 μm = 1*10^(-9) m

Objetos que pueden ser observados a simple vista:

Son todos aquellos objetos que podemos observar simplemente con nuestros ojos, con ellos podemos observar desde un edificio (con tamaños de decenas de metros) hasta algunos cabellos, que pueden tener un diámetro de 0.1 mm

Cosas más pequeñas que estás muy difícilmente se pueden ver a simple vista.

Con un microscopio podremos ver cosas del tamaño de una célula, como glóbulos blancos, rojos, algunos microorganismos, etc, los cuales rondan un tamaño de unos 10 μm. Naturalmente, distintos microscopios tendrán distintas amplificaciones (por lo que con algunos podremos ver objetos muy pequeños que con otros no).

Microscopio eléctrico:

Este microscopio usa electrones en lugar de luz para formar imágenes.

Con él podremos observar cosas como las componentes de una célula (membranas, orgánulos grandes, etc), los cuales pueden medir unos pocos nanómetros (por ejemplo, una membrana celular tendrá un tamaño de entre 5 μm y 10 μm)

Microscopio de transmisión.

Tener en cuenta que el microscopio de transmisión es un microscopio eléctrico, el cual lanza un haz de electrones al objeto que se desea observar, de tal forma que algunos de estos electrones rebotan formando así la imagen virtual amplificada que podemos observar.

Con estos aparatos podemos ver orgánulos pequeños (0.5 μm), y lo más pequeño que podemos ver (con los microscopios más potentes) son columnas de átomos (0.1 μm)

Given a graph of volocity v . Time what does a horizontal line represent

kifflom [539]

Answer:

Acceleration

Explanation:

For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive).

Waves are observed passing under a dock. Wave crests are 8.0 meters apart. The time for a complete wave to pass by is 4.0 second

Harlamova29_29 [7]

The distance between a trough and a crest is double the amplitude.

The distance between trough and crest is (9m - 6m) = 3m.

So the amplitude of those water waves is (3/2) = 1.5 meters.

For this question, we really don't need to know how far apart the crests are, or how often they pass. There may be more parts to the question, for which that information is needed.

For example:

-- What's the wavelength of the waves ? 8 meters.

-- What's the period of the waves ? 4 seconds.

-- What's the frequency of the waves ? 1 / (4 seconds) = 0.25 Hz.

-- What's the speed of the waves ? (8 m) x (0.25 Hz) = 2 m/s
