The Earth orbits around the Sun is the simple answer, which is good enough for most people.

However, a more accurate answer is that they both orbit the center of mass of the solar system.

Because the Sun has nearly 99.9 percent of the mass of the solar system, the

Earth orbits a point

that's normally just outside the Sun's surface. So, the simple answer is fairly accurate.

After the eradication of smallpox, the last samples of smallpox were kept for academic research in Centers for Disease Control and Prevention in the US and State Research Centre of Virology and Biotechnology in Russia. Both these institutions are under heavy guard to avoid the possibility of the theft of the samples for biological warfare.

Marshe are important because they filter pollution, prevent erosion and flooding, habitat for animals, provide food, recreation, research and education.

So in this case we should protect the wetlands.

Carl Linnaeus, or Carl von Linné (after being dubbed to knighthood in 1753 by king Adolph Fredrik of Sweden. In 1761 he was raised to the nobility and took the name von Linné.) was a botanist. His method of hierarchical classification and custom of binomial nomenclature is the basis for current day taxonomies. See the related article.

The five main components of blood are red blood cells, white blood cells, platelets, plasma, and serum. Red blood cells carry oxygen to tissues, white blood cells help fight infections, platelets help with blood clotting, plasma is the liquid part of blood, and serum is plasma without clotting factors.

The myelin is the fatty substance that's present in some kind of neurons, structured as an excess of membrane that does several turns around the axon, improving the electrical transmission along the axon. So, the transmission of electrical impulses in myelinated neurons are faster and more efficient than in the other types.

The term "doldrums" comes from the Old English word "dol," meaning stupid or foolish. It was originally used by sailors to describe the calm, windless parts of the ocean near the equator that made sailing difficult and slow. Over time, "doldrums" came to signify a state of inactivity, sluggishness, or boredom.

The nebular hypothesis posits that our solar system formed from a large rotating cloud of dust and gas composed mostly of hydrogen and helium, leftover from previous supernova explosions. Over time, gravity caused the cloud to collapse and form a protostar at its center, with a surrounding disk from which planets eventually coalesced.

Dmitri Mendeleev did not discover technetium. Technetium was discovered in 1937 by Italian scientists Carlo Perrier and Emilio Segrè. Mendeleev is known for creating the periodic table of elements in 1869.

Earth's crust and the solid rocky and brittle upper mantle are known as the lithosphere. This is broken up into a number of different sections or pieces known as tectonic plates.

Underlying the lithosphere is the asthenosphere made up of the softer mantle rocks that behave as a viscous fluid (like an extremely thick treacle).

Heat within the earth causes the asthenosphere to convect. This movement causes the overlying lithosphere to move as well.

Also where mantle material rises to shallower depths it undergoes a process known as decompression melting. This causes the formation of magma which rises to Earth's surface. This hot (and therefore lower density) material forms a raised area in the Earth's crust known as a mid-ocean-ridge. Gravity acts to try and pull the buoyant hot new crust back down and this force is transferred horizontally through the crust in a process known as "Ridge Push". As the material cools and travels away from the mid-ocean -ridge it sinks slightly back down due to it's increased density and so lower buoyancy.

Ultimately this dense oceanic crust may meet a tectonic plate composed of continental crust which has a lower density and is more buoyant than the oceanic crust. Because of this the denser oceanic crust is forced down below the continental crust. This process is known as subduction. The force of gravity acting on the subducting slab is transferred into the rest of the slab acting to pull it towards the subduction zone. This process is known as "slab pull".

There is no scientific evidence to support the claim that chondriana can reverse the aging process. While some supplements may support overall health and vitality, they cannot halt or reverse the natural aging process. It is important to be cautious of products that make exaggerated claims about anti-aging benefits.

That is known as smog, a mixture of pollutants, primarily from vehicle emissions and industrial activity, that can create a visible haze over urban areas.

The primary diamond deposits mined on Earth's surface are called alluvial deposits. These deposits are found in riverbeds, beaches, and other areas where diamonds have been carried and deposited by water.

Erosion on a mountain range formed by the collision of continental plates will lead to the formation of features like valleys, ridges, and peaks. Over time, the mountain range will begin to wear down, exposing different rock layers and creating a more varied topography. Water, wind, and other natural forces will shape the landscape as erosion continues.

The layer between the inner core and the mantle is called the outer core. It is composed of molten iron and nickel, which generates Earth's magnetic field through convection currents.

A place where two plates slip past each other moving in opposite directions is known as a transform plate boundary.

The emergence of two sexes likely occurred through a process called sexual differentiation, where genetic and developmental mechanisms led to the evolution of distinct male and female reproductive systems in organisms. This differentiation provided advantages for reproduction, genetic diversity, and adaptation to changing environments, ultimately promoting the survival and diversity of species.

Pollution is not stricktly a scientific term. It has been around in English since the middle ages and in Latin for a considerable period before that.

The original meaning is to foul or make dirty (in a visible manner) and could be applied to almost any aesthetic or organoleptic degradation of an object, view, holy place, etc.

Early scientists would simply have used an existing verb to describe the changed state.

Although used to describe all manner of environmental conditions pollution/polluted has a separate meaning from contaminated, adulterated or defiled

He proved that Priestley's experiment only worked when plants were exposed to sunlight. Concluding that Priestley had not performed his experiment without sunlight. Ingenhousz performed both in sun and dark presence.

Antonie van Leeuwenhoek is known for making the world's first practical microscope by devising special lenses. He used this microscope to make groundbreaking discoveries in the field of microbiology.
