(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.
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.

Answer:1) person 2) person
Explanation:
I just did the assignment
The correct answer is the computer's thermal energy will be transferred to the human.
Why does energy flow from the computer to the person?Computers are often devices that transform electrical energy into thermal energy, which is then supplied to the user. The energy is transferred from the higher to the lower amount. In this example, the computer produces more thermal energy than the person, which is why energy flows from the computer to the person.Learn more about computer thermal energy here:-

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

Water evaporating in an open system, water freezing, cookie dough baked into a cookie, and sugar dissolving into water are all examples of statements that demonstrate the law of conservation of matter.
What is law of conservation?A conservation law in physics asserts that a specific observable property of an isolated physical system doesn't change over time.A physical property, or measurable amount, does not change over time in an isolated physical system, according to the conservation law, often known as the law of conservation, which is a principle in physics.According to the principle of mass conservation, neither chemical processes nor physical changes can create or destroy mass in an isolated system. The mass of the products and reactants of a chemical reaction must be equal, in accordance with the law of conservation of mass.To learn more about law of conservation refer to:

What are the three parts of sound? (Select all that apply.)
the transfer of energy through a medium
the detection of sound
the identification of pitch
the energy source
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.
What is sound wave?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.

Explanation:
I hope this helps.
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.
