7. A student astronomer went out and took photographs of the Moon that were several days apart.
Images that look like her photographs are shown above. The light part of the Moon appeared to get
smaller over time. Why did this happen?
a
Between the first photograph and the second photograph, the Moon moved farther away
from the sun so less sunlight reached the Moon's surface.
b
Between the first photograph and the second photograph, Earth moved so its shadow was
blocking more of the Moon so the student astronomer was able to see less of it.
с
Between the first photograph and the second photograph, the Moon rotated so that less of
the light-colored rock on the Moon's surface faced Earth.
d
Between the first photograph and the second photograph, the Moon moved so that the
student astronomer was able to see less of the half that faces the sun.

A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.

Explanation:

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.

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.

Answer:

Answer:

The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

Answer:

5 metros.

Explicación:

Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.

Answer: Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Significant direct human health impacts can occur if ecosystem services are no longer adequate to meet social needs.

Explanation:

Humans are dependent on healthy ecosystems as they provide resources, regulate climate, purify water, control diseases, offer recreational and cultural values, and drive economic activities.

For a number of reasons, functioning ecosystems are essential to human existence. supplying resources Healthy ecosystems offer vital resources like food, fresh water, clean air, and building supplies like fibre and wood. These materials provide for our basic necessities and are essential to our survival. Genetic and biological diversity: Numerous plant and animal species are supported by ecosystems, which increase biodiversity. Ecosystem stability is ensured by biodiversity, which also increases resilience to environmental changes and offers genetic diversity. The creation of novel foods, medicines, and other useful goods depends on this diversity.

ANSWER: IT'S CALLED THE ZEROTH LAW OF THERMODYNAMICS

EXPLANATION:

The zeroth law of thermodynamics state that there's no heat transferred between two objects in thermal equilibrium (i.e having the same temperature). This phenomenon depicts that there's balance in the amount of temperature in all the three entities.

This phenomenon was credited to Sir Ralph Howard Fowler, a British physicist and astronomer during his lifetime.

A scientific paper by Carathéodory also added that when two systems S1 and S2 are made to reach equilibrium with a third system S3 under close thermal conditions, systems S1 and S2 are said to be in mutual equilibrium.

Answer:

In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.

A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

Answer:

Explanation:

Landfills are low-lying open areas specifically designed for the dumping of waste materials to be buried later.

Landfills can be for municipal/household wastes, industrial wastes, or for hazardous wastes. They are usually low lying to facilitate their burial after they must have been filled-up and they represent one of the oldest methods of disposing wastes.

Landfills are not just open areas, they are low-lying as opposed to high-lying, and they are not created near rivers or lakes.

The age of fossils are in millions.

Explanation:

These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.

Complete question:

Fill in the blanks.

The earth is ______ (warming, cooling, static, dynamic). This trend most closely follows trends in the Earth's ______ (albedo, distance from the sun, energy input from the sun, atmosphere). Within the Earth's ______ (albedo, mantle, atmosphere, crust) the component that is likely most responsible ______ (carbon dioxide, magma, water, humans).

Answer:

The earth is warming. This trend most closely follows trends in the Earth's atmosphere. Within the Earth's atmosphere is the component that is likely most responsible for carbon dioxide.

Explanation:

Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth. The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.

The current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.

The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole Earth´s history. It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities.

Answer:

A & C

Explanation:

In short terms, A & C are the only answers that have anything to do with the magnetic field. Solar wind is part of solar weather, and is involved in the creation of the other three answers. Auroras are formed through the interaction of solar wind and the oxygen & nitrogen in Earth's atmosphere.

The geomagnetic storms and auroras are the results from the interaction of solar weather on Earth's magnetic field. The correct options are A and B.

Solar or space weather refers to actions that take place on the Sun's surface.

These reactions usually have different effects on our planet, owing primarily to the Earth's magnetic field, which acts as a shield for the planet.

A geomagnetic storm happens when the solar radiation collides with the Earth's electromagnetic field, causing disruptions in the magnetosphere.

The interaction of loaded solar particles and the land based electromagnetic field produces an aurora, which is a luminescent formation.

The solar wind transports these particles to the terrestrial electromagnetic field, in which they are shown in various colors depending on the type of particle.

Thus, the correct options are A and B.
