The Earth's biodiversity is determined by the variety of all living organisms on Earth. In recent years, ecologists and other scientists have encouraged the preservation of global biodiversity through the protection and management of natural ecosystems. Preserving the biodiversity of the Earth is important because
Answers
Answer-:
Preserving the biodiversity of Earth is important because biodiversity increases the efficiency of ecosystems where every species, no matter how small, has an important role to play. A greater number of species of plants means a larger range of crops. Greater diversity of organisms guarantees ecological survival for all lifeforms
Explanation:
REASONS WHY PRESERVATION OF THE EARTH'S BIODIVERSITY IS IMPORTANT-
ECOSYSTEM PRODUCTIVITY - One of the key reasons we should continue to concentrate on biodiversity protection is that it helps to improve the efficiency of the ecosystem. Naturally, a properly working ecosystem would be more immune to extreme environmental factors, such as climate change.HEALTH DETECTIONS -The vast number of medical advances waiting to be made is one of the most significant reasons why we should continue working on saving biodiversity. To develop new cancer therapies and more, scientists use observations of plants , animals, and even microbes. As a matter of fact, all human drugs must first be tested before being tested on humans in laboratory animals. This is essential for determining their toxicity, dosing, as well as effectiveness. In some of the most remote sections of the planet, many of the animals used in these discoveries are also included. Recreation and Natural Beauty - The value of natural beauty is another great explanation why we should continue focusing on protecting biodiversity. There are several historical sites around the country that need to be preserved to maintain their status for future generations to enjoy, such as the redwood forest. These trees regularly have a lifespan of 600 years in the case of the redwoods. Some are as old as 2,000, too. Their growth is extremely sluggish, however. Wild and natural environments provide ways to get away from urban environments. In addition, people can enjoy outdoor activities such as bird watching, canoeing, hiking, and photography of nature. The Ecosystem 'Survival - With a few exceptions, to survive, each species on Earth relies on the services of other species. This partnership is part of the idea of what an ecosystem is. The relationship between soil, plants , and bacteria is a pertinent example. This is known as the period of nitrogen. Other examples which are important include -: Animal waste which nourishes the soil, Crops also produce straw, which is an animal food source, As natural nitrogen fixers, algae represent and Aerate the soil with rats.Economic Benefits -: Many advantages have been provided to humans through biodiversity, and many come in the form of products. These products are extracted and sold, and everything from crops to medicines is included.Hence, preservation of the biodiversity of Earth is important from all aspects of life.

Which of these factors best explains why liquid water exists on Earth?
A. Presence of living things
B. Moderate temperatures
C. Lack of gravity
D. Lunar tides
Answers
The factor that best explains why liquid water exists on Earth is moderate temperatures. Therefore option B is correct.
Liquid water exists on Earth primarily due to the presence of moderate temperatures. Water is a unique substance because it has a relatively high boiling point and a wide range of temperatures at which it remains in a liquid state.
The average surface temperature of the Earth, along with the atmospheric pressure, allows water to exist as a liquid under normal conditions.
The lack of gravity is incorrect because gravity is essential for the existence of liquid water. Gravity keeps water molecules attracted to each other, preventing them from dispersing into the atmosphere.

In the outer layer of the sun, energy is transported outward by the rising of hot plasma and sinking of cooler plasma. This transfer is known as
Answers
Answer: Convection.
Explanation:
We have 3 types of heat transmission.
Radiation: Heat is transported as electromagnetic waves, this is not the case shown here.
Conduction: When we have two objects with different temperatures and we put them in contact, the system will want to go to equilibrium (both objects have the same temperature) so the hot object will give heat to the cooler object. We usually see this with solid objects.
Convection: It is the heat transfer due to the bulk movement of the molecules, so this need a material medium (it can not take place in solids, because the position of the molecules is fixed in the solids).
Then the rising of hot plasma and sinking of cooler plasma is convection.

What problems can pseudoscience cause for society?
Answers
Answer:
It is quite difficult to picture a pseudoscientist—really picture him or her over the course of a day, a year, or a whole career. What kind or research does he or she actually do, what differentiates him or her from a carpenter, or a historian, or a working scientist? In short, what do such people think they are up to?
… it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.
The answer might surprise you. When they find time after the obligation of supporting themselves, they read papers in specific areas, propose theories, gather data, write articles, and, maybe, publish them. What they imagine they are doing is, in a word, “science”. They might be wrong about that—many of us hold incorrect judgments about the true nature of our activities—but surely it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.
