King of forest ( Big cats )

Big cats

The term big cat, while not a biological classification, is used informally to distinguish the larger field species from smaller ones.“Big cats” is a term commonly used in reference to large wild cats. The list of big cats  includes the different types of big cats worldwide, from tigers (the largest big cats) to clouded leopards (the smallest big cats).

The big cat species addressed in these regulations are the lion, tiger, leopard (snow leopard, clouded leopard ), cheetah, jaguar, cougar, and any hybrid combination any of these species that results from breeding of these big cats.

Top 5 big cats

1.Tiger 

            The biggest, largest and most heavy cat is definitely the tiger, especially the Siberian Tiger. Weighing just under a thousand! pounds (425kg), these giants roam the snowy plains of Russia. There are only about 350 Siberian tigers alive today.

They average about 80 inch (2 meters) long. And check this out: Black bears are this tiger’s dinner. Yeah that’s right, the massive black bear is a snack to this cat. This big kitten earns our number one spot and then some!

2.Lion

           Ask a random person what’s the biggest wild cat and they will probably answer with Lion. And a very logical assumption, although incorrect. But lions are the most famous wild cats, mainly thanks to Hollywood movies and especially since The Lion King. 

They can weigh up to 550 pounds (250kg) and they can be found in parts of Africa. There are 12 different subspecies (breeds if you will) of lions. Although the lion is not our number 1 big cat, it is the tallest.

And of all the big cats, only in lions is the difference between males and females so obvious. The male has the distinctive thick mane, the female (lioness) doesn’t have it. Even though the males get bigger, the female lions do all the hunting.

3.Jaguar

               The Jaguar is our number 3! Did you know you can also call a jaguar a panther and still be correct? That’s because panther comes from Panthera, a family classification of big cats including the jaguar and the leopard. 

Jaguars can be found in parts of the continent America. This beautiful big cat’s number are still declining, but efforts are being made to preserve this beautiful wild cat.

4.Cougar (Mountain Lion)

                                        The James Bond of the big cats, the cougar has many identities. Its known as Cougar, Mountain Lion, Puma, Panther and Catamount. A cougar can get about as big as an adult human. Cougars can be found on the continent of America.

There are many urban legends about cougars attacking humans, but most are not true. In about one hundred years there have been 53 reported attacks, and about 10 fatalities. Cougars do not see humans as prey and try to avoid human contact.

5.Leopard / Black Panther

                                           What’s this? Two cats sharing one spot? Nope, it’s the same species. The black panther is a leopard with a black coat. Its caused by melanism, a color variation that also appears with jaguars. Matter of fact, the Leopard and the Jaguar have more in common, they are very alike in appearance, except that the Jaguar is the Leopard big brother.

The Leopard has the largest tail among the wild cats. Their tail can get up to 43 inch (110cm) long. Leopards will eat about anything, from beetles to birds to monkeys and even elands.

This is in the advantage of the Leopard, because bigger predators will fight them for their prey. The Leopard will wisely walk away from any fight it knows it will lose, and simply choose a prey that the other predator won’t eat.

                                                                                                      law stating that the proportions in which two elements separately combine with a third element are also the proportions in which they combine together.

↔Dalton's law, law of multiple proportions - (chemistry)

                                                                               law stating that when two elements can combine to form more than one compound the amounts of one of them that combines with a fixed amount of the other will exhibit a simple multiple relation.

↔law of mass action - (chemistry)

                                                 the law that states the following principle: the rate of a chemical reaction is directly proportional to the molecular concentrations of the reacting substances.

↔Mendeleev's law, periodic law - (chemistry)

                                                               the principle that chemical properties of the elements are periodic functions of their atomic numbers .

↔natural science -

                           the sciences involved in the study of the physical world and its phenomena.

↔chemoimmunology, immunochemistry -

                                                         the field of chemistry concerned with chemical processes in immunology (such as chemical studies of antigens  and antibodies).

↔ Mendeleev's law -

                                                          the field of chemistry concerned with chemical processes in immunology (such as chemical studies of antigens and antibodies).

↔organic chemistry -

                              the chemistry of compounds containing carbon (originally defined as the chemistry of substances produced by living organisms but now extended to substances synthesized artificially).

↔inorganic chemistry -

                                 the chemistry of compounds that do not contain hydrocarbon radicals.

↔physical chemistry -

                               the branch of chemistry dealing with the physical properties of chemical substances.

↔electrochemistry -

                                branch of chemistry that deals with the chemical action of electricity and the production of electricity by chemical reactions.

↔femto chemistry - 

                           the branch of chemistry that studies elementary (often very fast) chemical reactions as they occur; the experimental methods are often based on the use of femto second laser pulses.

↔geochemistry -

                           the chemistry of the earth's crust.

↔photochemistry -

                                branch of chemistry that deals with the chemical action of light.

↔nuclear chemistry, radiochemistry -

                                                   the chemistry of radioactive substances.

↔surface chemistry -

                               the branch of chemistry that studies processes occurring at interfaces between phases (especially those between liquid and gas).

↔atomist theory, atomistic theory, atomic theory, atomism - (chemistry)

                                                                                                    any theory in which all matter is composed of tiny discrete finite indivisible indestructible particles; "the ancient Greek philosophers Democritus and Epicurus held atomic theories of the universe".

↔Arrhenius theory of dissociation, theory of dissociation, theory of electrolytic dissociation - (chemistry)

                                       theory that describes aqueous solutions in terms of acids (which dissociate to give hydrogen ions) and bases (which dissociate to give hydroxyl ions); the product of an acid and a base is a salt and water.

↔Ostwald's theory of indicators, theory of indicators - (chemistry)

                                                                                            the theory that all indicators are either weak acids or weak bases in which the color of the ionized form is different from the color before dissociation.
