Is this a scientific model? Use complete sentences to explain why or why not. i need help asap!!!!!!!!!!!!!!!!!!!!

Answer:

Osmosis is how plants are able to absorb water from soil. The roots of the plant have a higher solute concentration than the surrounding soil, so water flows into the roots. In plants, guard cells are also affected by osmosis. These are cells on the underside of leaves that open and close to allow gas exchange.

Hope this helps.

Answer: In biology osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.

Answer: I’m stuck between amplitude and wavelengths but I do think it’s wavelengths.

Correct me if I’m wrong! ^^

The human eye can only detect a portion of that spectrum because of the wavelength of the visible light waves. Therefore, option (B) is correct.

The wavelength of the light can be defined as the distance between the two adjacent points of a wave w.r.t. each other. Two crests on a wave are separated by a distance known as wavelength.

The frequency of the wave can be defined as the number of oscillations of a wave in 1 sec. The frequency has S.I. units per second or hertz.

The relationship between wavelength, frequency (ν), and speed of light (c) is as follows:

c = νλ

The part of the electromagnetic spectrum that is visible to the human eye is known as the visible spectrum. The electromagnetic radiation of the visible spectrum is known as visible light.

Human eyes can detect the wavelength of range from 380nm to 740nm. This wavelength range of visible light corresponds to a band of frequency between 405 THz to 790 THz.

Earth's plates travel at a rate too slow to be experienced by humans. It takes a long time for Earth's plates to travel great distances. The Mesosaurus fossils moved apart gradually over tens of millions of years.

Answer: There will be an increase in the boiling point with an increase in the molecular mass.

Explanation:

The melting point is the temperature at which the substance changes from a liquid state to a vapor state at a constant pressure. The pressure required to effect this change is known as the vapor pressure. The higher the vapor pressure, the higher the boiling point and the lesser time it takes for the substance to escape from the liquid state. In this case, a higher molecular mass means more energy is needed to make sure that there is a gaseous change. In addition, the higher melting point requires the lower temperature as well.

Step to step explanation:

Sound is resistance in air made by waves. In fact it is the transfer of energy through a medium and it have a source. The frequency of sound waves is called pitch. Hence the three parts of sound is options 1, 3 and 4.

Sound wave is a mechanical wave which transfer energy through a medium. There are two types of mechanical waves namely transverse wave and longitudinal waves.

Transverse waves are those in which the oscillation of particles is in a direction perpendicular to the wave. Whereas, in longitudinal waves, the direction of oscillation is along the wave.

Sound waves are longitudinal waves having certain frequency. The frequency of sound waves is called the pitch. Sound waves can be of low pitch or high pitch based on their energy. High energetic waves have higher pitch.

Here's the labeled list of different parts of a microscope using the word bank; Eyepiece (ocular lens), Objective lenses, Arm, Stage, Coarse focus, knob, Fine focus knob, Diaphragm or Iris diaphragm, and Light source (lamp or mirror)

Eyepiece (ocular lens): This is the lens at the top of the microscope that you look through to view the specimen. It typically provides a magnification of 10x.

Objective lenses: These are the lenses located on the rotating nosepiece, closest to the specimen. They come in different magnifications, such as 4x, 10x, 40x, and 100x, and are used to magnify the image of the specimen.

Arm: The arm is the curved part of the microscope that connects the eyepiece and the base. It is used to carry the microscope and provides a handle for holding it securely.

Stage: The stage is the flat platform where the specimen is placed for observation. It may have clips or a mechanical stage to hold the slide in place.

Coarse focus knob: This knob is used for large, rapid adjustments of the focus. It moves the stage up and down to bring the specimen into rough focus.

Fine focus knob: The fine focus knob is used for precise adjustments of the focus. It is used after the coarse focus to bring the specimen into sharp focus.

Diaphragm or Iris diaphragm: The diaphragm or iris diaphragm is located under the stage and controls the amount of light passing through the specimen. It helps in adjusting the contrast and brightness of the image.

Light source (lamp or mirror): The light source provides illumination for the specimen. It can be an electric lamp located at the base or a mirror that reflects natural light onto the specimen from above.

These are the essential parts of a compound light microscope, which is a widely used type of microscope for magnifying and observing small specimens in various fields such as biology, medicine, and materials science.
