how would the solar eclipse be different if the moon was moved AWAY from the earth?
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.

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.

Imagine that you are hiking and discover an outcrop of sedimentary rock. The rock is arranged in three distinct layers that appear to be undisturbed. When you examine the layers more closely, you observe fossils in the bottom and middle layers. What inferences can you make about these fossils based upon your observations and your knowledge of the law of superposition?
Answer:
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.

In bunnies long ears are dominant over short ears. If two heterozygous bunnies are crossed, what is the probability their offspring will have the long ear phenotype? 1. 25% 2. 50% 3. 75% 4. 100%
Answer: 75%
Explanation:
See my picture for my work. Use a punnett square.
Answer: 75%
Explanation:
Heterozygous means that one allele would be dominant, and the other would be recessive. I will use B for the dominant allele, and b for the recessive allele.
Next, create a Punnett square (look at the pic).
To make the Punnett square, draw a 2 × 2 table. Put Bb on the top (one over each column) and Bb on the left side (one next to each row). Cross multiply. Remember to always put the dominant allele (in this case, B) in front of the recessive allele (in this case, b). The dominant allele will always be exhibited in the organism. So, the answer is 75%, since 3/4 of the different combinations of alleles is long ears.
Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the fossil record in an attempt to discredit the theory. Which statement would be the best counter argument as to why the fossil record can be relied upon to support evolution?
A. The fossil record provides evidence that extinct species only fossilized during certain geological eras.
B. The fossil record provides evidence that extinct species are genetically identical to current species.
C. The fossil record provides evidence of many different types of organisms, since most species fossilize well.
D. The fossil record provides evidence of many transitional organisms that show relationships between species.
Answer:
D. The fossil record provides evidence of many transitional organisms that show relationships between species.
Explanation:
Evolution is the process of changes in characteristics of an organism as time passes. In order for fossil records to support this, there must be some linkage between species to species. Therefore the correct answer is D. The fossil record provides evidence of many transitional organisms that show relationships between species..
Since its inception, the theory of evolution has been the subject of frequent debate, and the fossil record can be relied upon, the fossil record provides evidence of many transitional organisms that show relationships between species, which is in Option D.
What is the significance of the fossil record?The fossil record tells about the ancestors and explains the diversity of life on Earth over thousands or millions of years ago. It is commonly found in sedimentary rock formations and provides information about how organisms lived thousands or millions of years ago.
Hence, since its inception, the theory of evolution has been the subject of frequent debate, and the fossil record can be relied upon, the fossil record provides evidence of many transitional organisms that show relationships between species, which is in Option D.

What data provides the strongest evidence (most valid) that early Earth conditions provided what was necessary for life?
A- Fossil evidence showing that prokaryotic cells required an environment free of oxygen.
B- Genetic comparisons revealing that living and extinct organisms share commonalities.
C- Geological dating techniques supporting theories regarding Earth's age.
D- Geological studies proving that volcanic gases resemble those from early Earth.
Answer:
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.
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.

. Landfill are is a/an: (a) open area (b) high lying open area (c) open area near a river/lake (d) low lying open area
Answer:
d
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.

Why are humans dependent on healthy ecosystems throughout the world?
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.

3. How would the bat population influence the number of cactus fruit that develop?
!!!!!!!!!!!!!!!!!!!!!!!!!
As the months pass, the table shows that the number of bats also causes an increase in the number of cactus flowers and fruit.
The cactus fruit don't seem to form in large number until the cactus flowers are also going up more in number. This is because pollination is necessary to form the fruit.
Based on this information:
The more bats in the population, the more pollination takes place, and the more cactus fruit is available as a result.
However, if the bats hit carrying capacity, they will be at a population number that is now bad for the number of cactus fruit, since there won't be enough food to feed the population- as more bats eat more fruit, the cactus isn't able to keep up with growing enough fruit to feed the bats at carrying capacity.
A heater provides heat to an area, but the temperature in the area stays about the same. What do you already know about this phenomena?
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.
