The electromagnetic spectrum is the portion of energy that reaches the Earth from the Sun. However, the human eye can still only detect a portion of that spectrum because of the _____________ of the visible light waves.
amplitude
wavelengths
crests
troughs
Answers
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.
What are frequency and wavelength?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.

(HELP I DONT KNOW HOW TO DESCRIBE IT BUT I SEE THE SIMILARITIES) Look at the green lines you created by connecting the three boiling point data points and the three melting point data points. For each of these lines, describe any trends you see.
Answers
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.

How does osmosis affect plants?
Osmosis allows more sunlight to enter the plant.
Osmotic pressure helps plants to keep its rigid structure.
Answers
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.

Answers
Answer:
C
Explanation:
The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Milky Way can be referred to as the galaxy which contains Earth . The milky way also comprises of other solar systems such as the Sun and billions of stars.
The name 'milky way' came about as a result of how the sky looks when viewing it at night. It contain several bands of color in a milky manner which are usually difficult to differentiate.
The milky way comprises of different processes such as force of gravity acting on it and also the channeling of energy needed to produce stars which aids vision in the night.
