Which material would get electrons from the source to the load the fastest
Answer:
However, graphene has far fewer electrons than copper, so in graphene the electrical current is carried by only a few electrons moving much faster than the electrons in copper." In semiconductors, a different measure, mobility, is used to quantify how fast electrons move.

After concluding his research, which statements would Virchow agree with? CHECK ALL THAT APPLY.
Living things come from nonliving things.
Cells can come from nonliving materials.
Frogs can come from mud.
Living things can only come from living things.
Cells come from pre-existing cells.
Answer:
Living things can only come from living things.
Cells come from pre-existing cells.
Explanation:
Rudolf Virchow a german physicist, biologist and many more, In 1855 Vproposed that cells come from pre-existing based on his observations in exact words 'Omnis cellula e cellula', which translates into all cells arise from pre-existing cells.
He also said the living things come from living things and do not arise from nonliving things or matter. His discoveries made possible the cell theory

Which process do all organisms do when performing cellular respiration?
Answer:
Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.
This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.
So, glycolysis is the process that all organisms do during cellular respiration.
Glycemia refers to the amount of glucose in a person's blood. What does it mean that the patient was
hyperglycemic? Why did this affect the doctor's decision to give the patient a normal IV?
Explanation:
A person that is Hyperglycemia has a high blood pressure causing problems, iv help maintain people blood sugar if u use a normal iv it might cause a high blood pressure can cause blood clot to form in your arteries leading to the brain blocking blood flow causing a stroke. I hope this helps
Define Physical Properties?
Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables.

Diffusion in membrane cell
Answer:
when small molecules pass through the lipid bilayer of a cell membrane simple passive diffusion occurs
Explanation:
Diffusion is one form of passive transport that doesn't require the expenditure of cellular energy. A molecule can diffuse passively through the cell membrane if it's lipid-soluble, uncharged, and very small, or if a carrier molecule can assist it. ... The assisted process is known as facilitated diffusion.

Phycobiliproteins are complex proteins in cyanobacteria that absorb light energy. There are three kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin—responsible for capturing green light, phycocyanin—responsible for capturing orange-red light, and allophycocyanin—responsible for capturing red light.
Since light can only penetrate to certain depths in oceans (figure 1), phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll. (4 points)
A. Explain the relationship between chlorophyll absorption and wavelength.
B. In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best justifies the claim that this species is better adapted to environmental changes than the cyanobacteria described above?
Answer:
Part A:
— Chlorophyll absorbs different wavelengths than chlorophyll does.
— Chlorophyll does not absorb wavelengths that are green and yellow, which is indicated by a very low degree of the light absorption.
Part B:
Photosynthetic Organisms are organisms capable of photosynthesis. Photosynthesis is greenery and other organisms using the energy from sunlight to synthesize foods from carbon dioxide and water. Leaving allophycocyanin to be the protein these plants and other organisms receive from the light. So for the process, in order for the plants to live they must be able to go through photosynthesis giving the plants the energy and proteins they need to produce food and to release oxygen into the environment.
Answer:
The visible spectrum is the only part of the electromagnetic spectrum that can be seen by the human eye. It includes electromagnetic radiation whose wavelength is between about 400 nm and 700 nm.
Visible light from the sun appears white, but it’s actually made up of multiple wavelengths (colors) of light. You can see these different colors when white light passes through a prism: because the different wavelengths of light are bent at different angles as they pass through the prism, they spread out and form what we see as a rainbow. Red light has the longest wavelength and the least energy, while violet light has the shortest wavelength and the most energy.
Photosynthesis, the sun’s energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis. Instead, photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light, while reflecting others.
The set of wavelengths absorbed by a pigment is its absorption spectrum. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color. For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.
Although both chlorophyll a and chlorophyll b absorb light, chlorophyll a plays a unique and crucial role in converting light energy to chemical energy (as you can explore in the light-dependent reactions article).
All photosynthetic plants, algae, and cyanobacteria contain chlorophyll a, whereas only plants and green algae contain chlorophyll b, along with a few types of cyanobacteria Because of the central role of chlorophyll a in photosynthesis, all pigments used in addition to chlorophyll a are known as accessory pigments—including other chlorophylls, as well as other classes of pigments like the carotenoids. The use of accessory pigments allows a broader range of wavelengths to be absorbed, and thus, more energy to be captured from sunlight.

polar
non-polar
Answer:
The nature of the indicated covalent bond is polar.
Explanation:
The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.
In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.
CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.
The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.
How was the rotation rate of Jupiter's core determined?

-by watching lo move across the disk of Jupiter
-by radio observations of Jupiter's rapidly spinning magnetosphere
-by measuring the oblateness of Jupiter's disk
Answer:
C. by radio observations of Jupiter's rapidly spinning magnetosphere
Explanation:
Jupiter refers to one of the planetary bodies in the solar system. It is considered to be the largest (twice as large or big as every other combined) planetary body and the fifth (5th) from the Sun.
Jupiter is a planet that rotates rapidly and as a result it is referred to as being noticeably oblate. It has the fastest rotation rate among the planets of the solar system because it completes a rotation about an axis in 9.9 hours.
The rotation rate of Jupiter's core was determined by radio observations of Jupiter's rapidly spinning magnetosphere.

Answer:
In the presence of light, chlorophyll (a substance that gives the leaves a green color) releases oxygen and produces carbohydrates, which enable the plant to grow. This complex process is called photosynthesis.
Explanation:
The roots are used to take dissolved mineral elements from the soil. The root is not capable of absorbing even the smallest organic or solid element. This means that it is important that the soil contains a certain amount of water, but also microorganisms, which have the task of decomposing organic matter and releasing the mineral elements from which it is composed.

State a technology and
explain how it is used to
forecast a future event.
I don't really know your question but I will tell you what can be predicted.
But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.
