Describe and explain how the surface of the early Earth and its atmosphere have changed

Biology
1 answer:
Yuliya22 [10]2 years ago
8 0

Earth had essentially no atmosphere when it originated 4.6 billion years ago from a heated mixture of gases and minerals. The ground had melted on it.

An atmosphere developed when Earth cooled, primarily from gases released by volcanoes. It contained methane, hydrogen sulfide, and ten to 200 times as much carbon dioxide as the atmosphere we are surrounded by today. The Earth's surface began to cool and solidify after roughly 500 million years, allowing water to accumulate there. Although life on Earth continued to develop and diversify, such periods of expansion and development were halted by mass extinctions, in which many of the planet's major life forms were either entirely or partially wiped out and many others were freshly established. Such catastrophic extinction episodes are attributed to asteroids impacts, climate change, volcanic eruptions, etc. Dinosaurs were also wiped out in one such event. The largest problem the Earth is currently experiencing is climate change brought on by human activity. Although human activities may exterminate some species from the world, the planet will undoubtedly recover and return to its natural balance as it has for millions of years. However, the sun will ultimately wipe out Earth, as predicted by scientists. The Sun will lose its structural integrity and enlarge in volume as it ages and eventually runs out of the fuel that keeps it going—hydrogen—which will cause it to burn everything in its path, including life on Earth. In the end, the Sun would perish, leaving the Solar System permanently in the dark.

juin [17]

Answer:

The correct answer is - health hazards (carcinogenic).

Explanation:

Processed foods, cured meat, and certain types of wines have a chemical present in them for increasing the life of the food and taste. This chemical is used in this food are known for their cancer-causing properties and grouped as group 1 carcinogen which comes under health hazard of type of chemical hazard.

N-nitroso-compounds (NOC) and polycyclic aromatic hydrocarbons (PAH) are the two major chemicals used in cured meat and processed food. There are many other severe health conditions also caused by ingesting a high amount of such food like diabetes, cardiovascular disease, and obesity.

Fiesta28 [93]

Answer:

B.

The flagellates and termites share an obligate mutualistic association

Explanation:

Organisms of same or different species tend to interact with one another in an ecosystem. The close interaction between two organisms is referred to as SYMBIOSIS. A type of symbiotic relationship is MUTUALISM, which is when both organisms benefits from the relationship.

However, mutualistic relationship can be of different types depending on how dependent the involved organisms are on each other. The example in this question illustrates OBLIGATE MUTUALISM, which is when the organisms involved in the mutualistic relationship depend on one another for survival. This is the case of the termites and the flaggelates where the termite depends on the flaggelate for enzymes that helps them digest cellulose while the flaggelates depend on termite for nourishment/food.

The termite will not survive if it doesn't get enzymes to digest its cellulose while the flaggelates will also not survive if they do not get nourished. Hence, the two organisms share an OBLIGATE MUTUALISTIC RELATIONSHIP.

1.       Less Maintenance Cost

2.       Cheaper cost

3.     There will be knock-on welfares as products will be industrialized with new applications where the price acceptance is much lower

4.     As these technologies progress and learn to treat high measurements of water, we will see cheaper, more filtered treatment systems and we will start to move away from enormous unified treatment systems.

5.     The technologies help to remove any matters from water, microbes, and bacteria
