Answer:
Each of the different colors has its own wavelength, which reflects and refracts at its own angle, different from all the other colors. When light passes through a prism (a triangular piece of glass), it is reflected and refracted into a continuous band of colors called a spectrum.
Explanation:
Answer:
Colorful gasses;
When light passes through gas in the atmosphere some of the light at particular wavelengths is scattered resulting in darker bands. These lines came to be known as 'spectral lines' and were cataloged by heating common elements until they produced light and measuring the wavelengths emitted.

Which best explains why the rate of a reaction decreases at significantly higher temperatures?
A. The activation energy increases.
B. The shape of the enzyme changes.
C. The enzyme-substrate complex forms.
D. The bonds between substrates are broken.
Answer:
B
Explanation:
At significantly higher temperatures, the rate of an enzyme-catalyzed reaction decreases because the shape of the enzyme changes at high temperatures. Enzymes are proteinous in nature, and as such, are generally sensitive to high temperatures.
They simply become denatured by high temperatures. In other words, they lose their original shape and their catalyzing abilities as the temperature gets progressively high during the course of reactions, thus, decreasing the rate of a reaction.
The correct option is, therefore, B.

A converging lens can be defined as ___
A) a lens that causes parallel light rays to bounce off the surface
B) a lens that causes parallel light rays to separate from each other
C) a lens that allows parallel light rays to pass without changing directions
And D) a lens that causes parallel light rays to focus at a specific location
Answer:
D) a lens that causes parallel light rays to focus at a specific location
Explanation:
Lexically, to CONVERGE means to MEET. Converging lens, also known as double convex lens is that which causes rays of parallel light to become focused at a point i.e meet at a specific location.
The parallel rays of light come from different direction but the converging lens is structurally suited to cause them to converge or focus at a point.
Why do geologists think Earth's core contains mostly iron?
A. The crust contains a mixture of iron and silicon.
B. The crust contains no nickel.
C. Other orbiting bodies contain more iron than Earth's crust does.
O D. The moon's crust contains far less iron than Earth's crust.
Answer:
It should be D
Explanation:
I hope this helps! Let me know if I am wrong.
The geologists think Earth's core contains mostly iron is to be considered as the option c. Other orbiting bodies.
Reason for thinking of geologists:Here the thinking should be earth core that comprises iron since the earth should contain the powerful magnetic field that is due to the molten iron in the core.
Also, there should be constant movement leads to the electrical current.
hence, the option c is correct.

2. Just as in humans, systems interact in plants to maintain homeostasis and accomplish the functions of transport, reproduction, and response. What are some examples of plant processes that involve an interaction between stems, roots, and leaves?
Answer:
osmosis
Explanation:
plants use osmosis whic is moving water though a semipermial membrane to draw up water. It moves from places of high conetartions of water (dirt) has to is less water (roots). When it does this the plant mains homeostasis by getting water up useing their xylem (tubes in stems) to the leaves.
Plants use osmosis which is moving water though a semipermial membrane to draw up water.
What do you mean by osmosis?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential.
Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.
The rate of osmosis always depends on the concentration of solute. The process is illustrated by comparing an environmental or external solution to the internal concentration found in the body.

Which of the following is NOT in part of the natural selection process?
A. a species produces more offspring than can survive
B. an organism adapts to their environment causing variation
C. individuals competing with each other
D. fossils being formed
Answer:
the selection that is not a natural selection process is D: fossils being formed
Answer:
D. Fossils being formed
Explanation:
In the natural selection process, the point is that the animal which is best adapted to the environment survives, so their offspring can survive and produce more offspring that adapts. This is because organisms need to adapt to their environment to survive. Without natural selection, most animals would be too weak to live in their own habitat.
So when we see the answer choices, we have to ask if the species could continue to live and adapt.
A- the species produces more offspring that can survive. Yes, the species can continue to live and adapt.
B- an organism adapts to their environment. Yes, the species can continue to live and adapt.
C- individuals competing with each other. Yes, the better species will win, and continue to live and adapt
D- fossils being formed. No, this has nothing to do with the process of living and adapting. It is in fact the opposite, since it relates to the species dying.
So the answer is D

Which has a lower albedo, a black sheet of paper or a white sheet of paper?
Well let's see, the substance with the highest albedo value will absorb less light and will reflect most of the light falling on it. The substance having the lowest albedo will absorb most of the lights falling on it. A black sheet of paper will absorb most of the light falling on it, so this means that a black sheet of paper will have the lower albedo
