Thanks OP for answering your own question!
The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.
What are genetic comparisons in evolution?Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.
Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

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.

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.
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.

Termites are unable to digest some plant materials (fiber). Termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
commensalism
mutualism
parasitism
competition
The relationship between the termite and bacteria is called mutualism.
What is mutualism?Mutualism is the kind of relationship between two organisms in which both organisms benefit from one another.
According to this question, termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
This means that both the termite and bacteria are benefitting from the relationship, hence, is a type of mutualism.

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.

Like a chimney we make heat to warm up our houses! Or some people use furnaces it also produces heat and warms up your room or house! Well now that we know what we use it for ....What is heat?
Of course Heat!
Heat is The energy that transfers to many different entities With a slight or major temperature difference!Please take in mind that heat only transfers to objects that are cooler than heat itself!Which means that it is energy that is transferred (or that flows ) from one object or system to another!
More info!

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.
Joseph sets up an experiment growing corn in three containers. Each container has the same amount of
potting soil and fertilizer. Each corn plant is five centimeters (cm) tall. The containers are all placed so thatthey
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.
Explanation:
Because that is the only variable being altered or changed, every other variable remains consistent. In any experiment what your testing is what's altered between each subject or test group.
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.
