How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.

Birds help take care of each other's young to increase their chances of survival, and the behavior is passed on to offspring.
What is an adaptive social behavior?Adaptive social behavior refers to actions or behaviors exhibited by individuals or groups that enhance their survival or reproductive success. In this case, the birds engage in cooperative parenting, where individuals assist in raising the offspring of others within their social group.
By providing care to the young of other birds, they increase the chances of those offspring surviving and passing on their genes. This behavior benefits the overall reproductive success of the group and is likely to be passed on to future generations, as it contributes to the survival and well-being of the species.

Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? View Available Hint(s) Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.
Answer:
Lionfish is introduced in this region.
Explanation:
The lionfish populations near the eastern United States is considered as an invasive species because this fish is not native species of this region and they were introduced into this region. Due to no predator available for this lionfish will make it invasive species that eliminated the local fish species and disturb the ecosystem. Lionfish are native to the tropical Pacific and there are no natural water routes of warm water between the Pacific and Atlantic oceans which helps this lionfish to reach eastern United States so we can say that it was introduced by humans.

the maria have few craters compared to the surrounding areas because ______
Answer:
Due to absence of erosive agents.
Explanation:
The Maria have few craters compared to the surrounding areas because of no erosive agents such as winds and rain. The erosive agents only formed when there is atmosphere in the region. The atmosphere is responsible for the presence of winds and rainfall. If these erosive agents are present, there will be more craters as compared to the region where no erosive agents are present so that's why Maria have few craters in the region. as compared to the surrounding region.

Explain why Calix's cells having more DNA than a normal cat meant point mutation was not the cause.
Mutation is the reason for the more DNA in Calix's cells.
Calix's cells having more DNA than a normal cat because of the mutation in the genes. There is no other way through which DNA in a gene increases. This increase in DNA from a normal condition leads to cancer and other disorders.
Mutation occurs in an organism when they are exposed to radiation which damaged the DNA of that organism so we can conclude that mutation is the reason for the more DNA in Calix's cells.

Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity in the neighborhood you chose.
Hello. You have not shown the neighborhoods to which the question relates, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The best way to reduce spending on carbon dioxide and increase biodiversity in a neighborhood is to provide tree planting through urban afforestation. A well-wooded neighborhood, it has a lower concentration of carbon dioxide because the plants absorb this gas releasing oxygen in place. In addition, some animals such as birds would attract them, in addition to promoting fruit and shade for the neighborhood.
Answer:
The most ideal way to lessen spending on carbon dioxide and increment biodiversity in an area is to give tree establishing through metropolitan afforestation. A well-lush area, it has a lower centralization of carbon dioxide in light of the fact that the plants assimilate this gas delivering oxygen set up. Likewise, a few creatures, for example, birds would draw in them, as well as advancing products of the soil for the area.

Suggest how humans might contribute to a
mass extinction event.
Answer:
Deforestation, hunting, pollution, the introduction of various regions of non-native species, and the widespread transmission of infectious diseases spread through livestock and crops.
Explanation:
An elementary school science teacher decided to liven up the classroom with a salt-water aquarium. Knowing that salt-water aquaria can be quite a hassle, the teacher proceeded stepwise. First, the teacher conditioned the water. Next, the teacher decided to stock the tank with various marine invertebrates, including a polychaete, a siliceous sponge, several bivalves, a shrimp, several sea anemones of different types, a colonial hydra, a few coral species, an ectoproct, a sea star, and several gastropod varieties. Lastly, some vertebrates - a parrotfish and a clownfish - were added. She arranged for daily feedings of copepods and feeder fish.
The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that by providing live copepods (2 mm long) and feeder fish (2 cm long) the dietary needs of all of the organisms would be satisfied. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)?
1. sponges
2. coral animals
3. bivalves
4. sea stars
5. shrimp
Answer:
sponges
Explanation:
because sponges need photosynthesis in order manufacture their food
The organisms namely sponges and coral animals are most likely to starve to death in the lack of photosynthetic endosymbionts. The correct option is 1 and 2.
What are endosymbionts?Endosymbionts are organisms that live in close proximity to another cell or organism.
As sponges are predominantly filter feeders, consuming detritus, plankton, viruses, and bacteria. They also absorb nutrient solution from water directly through their pinacocyte cells.
Due to the lack of photosynthetic endosymbionts the organisms namely sponges and coral animals are most likely to starve.
Thus, the correct option is 1 and 2.

How does the presence of cosmic microwave background radiation support the big bang theory?
Check all that are true.
-It shows that here is a faint, leftover energy that is coming from all directions of the universe.
-It shows that the universe used to be smaller with a uniform temperature.
-It shows that the universe is coming back together and will collapse in a massive black hole.
-It shows that all matter and energy in the universe is accelerating.
Answer:
I'm pretty sure that it's B
It shows that the universe used to be smaller with a uniform temperature. Therefore, option (B) is correct.
What is cosmic microwave background radiation?According to the theory of the Big Bang, the cosmic microwave background is an electromagnetic radiation that is a relic from an earlier stage in the development of the universe. This radiation is also known as "relic radiation." The Cosmic Microwave Background (CMB) is the weak radiation that permeates all of space.
One of the primary confirmations of the Big Bang is thought to be its discovery and thorough studies of its attributes. The cosmic background radiation was accidentally discovered in 1965, which shows that the early cosmos was dominated by a radiation field with extraordinarily high temperatures and pressure.
