Why are the reactions that occurred in early earth different from modern Earth?
because of the help of a living being in the form of plants/algae that enrich oxygen on earth, then after the oxygen is fulfilled, son, then living creatures such as animals, etc. will develop.
The reactions that occurred in early Earth were different from modern Earth due to several factors related to the planet's initial conditions and its subsequent evolution over billions of years.
1. Atmosphere: The early Earth had a drastically different atmosphere compared to the present one. It was primarily composed of gases like methane, ammonia, and water vapor, lacking significant amounts of oxygen. Modern Earth's atmosphere, on the other hand, is predominantly nitrogen and oxygen, with trace amounts of other gases.
2. Temperature: Early Earth was much hotter than it is now due to intense volcanic activity and the planet's heat from its formation. Over time, as the Earth cooled down, the temperatures became more conducive to different chemical reactions.
3. Surface conditions: The early Earth had a more active and geologically dynamic surface with frequent volcanic eruptions, impacting the types of reactions that could occur. Today, the Earth's surface is relatively stable and has developed diverse ecosystems.
4. Availability of elements: The abundance and distribution of elements on early Earth were different, as various geological and cosmic processes have influenced the planet's elemental composition over time.
5. Biological influence: Life itself has significantly impacted the chemical reactions on Earth. Early life forms, such as cyanobacteria, played a vital role in oxygenating the atmosphere through photosynthesis, which led to significant changes in the chemistry of the Planet.
These factors collectively shaped the early Earth's chemical landscape, fostering reactions that were distinct from those observed in the modern Earth we know today. As the planet evolved, so did its chemical and physical processes, leading to the diverse and complex environment we now inhabit.

maritime tropical
continental tropical
Answer:
Maritime polar
Explanation:
In the image, the maritime polar is the air mass that has formed immediately at the north of Antarctica.
Whta is a maritime polar air mass?A maritime polar air mass is a type of mass of extremely cold atmospheric air generated in the Noth and South poles.
These polar aim masses travel to lower latitudes in order to produce important rain precipitations.
As maritime polar air masses move they may collect warm and moist air from the surrounding ocean water.
In conclusion, the maritime polar is the air mass that has formed immediately at the north of Antarctica.

Which example best illustrates the point behind the Tragedy of the Commons essay? A.Various nations overfishing in international waters, leading to a collapse of fish stocks. B. A property owner clear-cutting all of the trees on his land to sell for timber. C. A farmer that over plants his fields one year, leading to a poor harvest. D. One country declaring war on another.
Answer: B. A property owner clear-cutting all of the trees on his land to sell for timber.
Explanation:
The tragedy of the commons is a problem whereby an individual pursue his or her own personal gain at the expense of the overall well-being of everyone in the society.
In this question, the tragedy of commons will be a property owner clear-cutting all of the trees on his land to sell for timber. Even though the owner makes some income for himself, this act will bring about soil erosion, depletion of resource or flood. He neglected the society in order to satisfy his own needs.

The factor that most directly limits variety of herbivores in an area is : ( C ) types of plants presentThe lowest trophic level of the food chain is : ( B ) some kind of plant The overpopulation of coyote in an area will lead to : ( D ) An increase in competition between the coyote HerbivoresHerbivores feed on variety of plants because not all herbivores feed on the same type of plant therefore an area with a variety of plants or grasses will have a variety of herbivores as well.
Trophic levelThe lowest trophic level in a food chains are the primary producers which are green algaes and green plants.
Effect of overpopulationOverpopulation leads to increase competition for basic amenities such as food, shelter and water. therefore the resulting effect of the overpopulation of coyotes is an increase in competition amongst themselves.

What is carbon fixation, and how does it relate to photosynthesis?
It is the absorption of CO2 from the air, and it occurs during the light-dependent reactions.
It is the reduction of CO2, and it occurs during the Calvin cycle.
It is the conversion of CO2 into organic compounds, and it forms 3-PGA.
It is the production of CO2 during regeneration, and it forms RuBP.
Answer:
It is the conversion of CO2 into organic compounds and it forms 3-PGA.
Explanation:
Carbon fixation is one of the three stages in which the light independent phase of photosynthesis is divided into. It is the process whereby CO2, an inorganic source of carbon, is accepted by RUBP, leading to the formation of a 6-carbon compound that disintegrates into two 3-carbon molecules due to its instability.
The 3-carbon compounds are 3-phosphoglycerate or commonly known as 3-PGA. The carbon fixation stage is followed by reduction stage.

are SARS-CoV-2 infection and transmission study on humans rather than animal models unethical?
Answer:
No. As long as these studies are supervised by ethics committees of human research
Explanation:
In medical research, ethical committees are responsible for ensuring that experimentation and methodological studies on human subjects are carried out in accordance with national and international well-established guidelines. In general, experimentation on human subjects is framed in a line of phased clinical trials. The ethics committees are organizations composed of medical specialists, scientific researchers, non-medical and non-scientific members who work together to ensure the protection of the rights, health and safety of the human subjects involved in such clinical trials.
SARS-CoV-2 infection and transmission studies on humans instead of animal models are ethical thanks to the supervision of the ethics committees.
The answer is no, As long as these studies are supervised by ethics committees of human research.
The ethics committees are organizations composed of medical specialists, scientific researchers, non-medical and non-scientific members who work together to make sure the protection of the rights, health, and safety of the human subjects involved in such clinical trials.
