Moving a book to a lower shelf decreases potential energy.
True
False
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.
What is Mutualism?A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.
A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.

No decorrer das semanas, a lua apresenta diferentes aspectos. A causa para essas mudanças na aparência do satélite da terra é: A) a sombra da terra refletida sobre a lua. B) o movimento de rotação da lua em torno do seu próprio eixo. C) os raios solares que incidem na superfície da lua. D) a translação da lua ao redor da terra.
Answer:
C) the sun's rays that fall on the moon's surface.
Explanation:
The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.

How did New Zealand's early ecology affect which traits were selected for/against in the kakapo's ancestors?
Answer:
Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.
Explanation:
New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.

What protein function listed here suggests that most enzymes are proteins?
A) provide structural support
B) transport substances inside the cell and between cells
C) communicate signals within the cell and between cells
D) speed up chemical reactions
E) control cell growth
The protein function listed here which suggests that most enzymes are proteins is that they speed up chemical reactions. That is option D.
Proteins are one of the classes of food that contains nitrogen in addition to carbon, hydrogen and oxygen.
Enzymes are those substances that helps in the breaking down of food substances into simple, soluble and diffusible substances before they can be absorbed into the body. It speeds up chemical reactions in the body by lowering the activation energy.
Enzymes are often referred to as proteins because proteins speeds up biological processes (chemical reactions) which is the same function performed by an enzyme in a living organism.

receive the same amount of light. All of the plants are grown at the same temperature. The plants are
watered once a week: container #1 receives 10 ml of water, container #2 receives 20 ml of water, and
container #3 receives 30 ml of water. Joseph measures the growth of each plant for six weeks.
Which hypothesis is being tested?
The amount of water supplied will affect plant growth.
The temperature will affect plant growth.
The type of fertilizer will affect plant growth.
The amount of light exposure will affect plant growth.
Answer:
The amount of water supplied will affect plant growth is the hypothesis being tested.

Pablo and Johanna have to do a yearlong study for their biology course. After some discussion, they decide to try comparing their dogs and the diet that they feed them. Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd-mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster-growing dogs. The reason the instructor gives them will include the fact that they have too many ______
Answer:
The correct answer is - variables that they didn't control and not enough replicates
Explanation:
In this particular case, Pablo and Johanna using too many variables in their experiment or research, All the variables used, are not controlled and with time these variables can not be replicated again on experiment groups.
They did not select a particular age or weight of dogs, the diets are different and they feed dry kibble to only one dog. There are so many variables and for a better result experiment, all variables should be controlled only the independent variable is permitted to manipulate.

Matt use a camera to take a picture of a rose on a piece of paper in the picture the rose appear to be bright red and the background appear to be white then Matt place a blue glass filter over the camera lens and took another picture in this picture of the Rose appear to be black in the background appear to be blue explain what happens to light waves to make the appearance of the rules in the appearance of the background different in the two pictures.
The blue glass filter absorbed most of the red light waves and allowed only the blue light waves to pass through, resulting in the appearance of the rose and the background being different in the two pictures.
What is Light?
Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in straight lines and has both wave-like and particle-like properties. Light is a fundamental part of our world and plays a crucial role in our lives.
Light is produced by the motion of charged particles, such as electrons, and can be emitted by sources such as the sun, light bulbs, and fires. Light travels at a constant speed of approximately 299,792,458 meters per second in a vacuum, which is known as the speed of light.
When Matt took the first picture of the rose on a piece of paper without any filter, the camera captured the visible light waves that were reflected by the rose and the background. The rose appeared bright red because it reflects mostly red light waves and absorbs other colors, and the background appeared white because it reflects all the visible light waves equally.
