Answer:
In 1749 A.D. George Wofan, a French scientist, put forward the theory of evolution of the Earth for the first time. According to his theory the Earth along with other planets and satellites, was formed when a comet moving around the universe stroke the sun many years ago.
Explanation:
In 1775 A.D., a German philosopher Kant put forward another nebular theory, which was later improved by Laplace in 1796. According to him, there was a gaseous mass revolving around the earth. While revolving, this mass began to cool and shrinked resulting many smaller masses. These smaller masses began to move round the larger central mass. This central mass became the sun and over revolving bodies formed planet and satellites.
According to hypothesis proposed by Jeans and Jeffery in 1917 A.D., a big star orbiting round the sun finally approached it. The star with its own attraction caused a tide to be developed from the sun. As this fragmented tidal matter cooled, planets, satellites, etc. were formed and the solar system was created. In this process, the Earth was also formed.
Any two geological Era are as follows:
Palaeozoic era: Palaeozoic era was began from 540 million years ago and ended at 250 million years ago. In this era, the plants and animals were found tohave developed which was found from the studies of the fossils remained in sedimentary rocks. Similarly, it is also believedthat there was a change in atmosphere and whether. This era is divided into six periods.
Mesozoic era: Mesozoic era began from 250 million years ago and ended at 65.5 million years ago. In this era, different types of hills and mountains were formed. It is supposed that the vital conditions for the survival of life on land, water and air were formed. This era is divided into three periods.
Which of the following best describes Recombinant DNA?
A. A bacterial plasmid with a target gene inside it.
B. A plasmid and restriction enzyme.
C. DNA that has been copied into an mRNA strand.
D. A bacterial gene with a target plasmid inside it.
The option that best describes Recombinant DNA is a bacterial plasmid with a target gene inside it. Thus, the correct option is A.
What is Recombinant DNA?Recombinant DNA may be defined as the methodology of adjoining DNA molecules from two different sources and inserting them into a host organism, to synthesize products for human use. It involves the principle of recombinant DNA technology.
DNA that has been copied into an mRNA strand is a normal process of transcription. A plasmid and restriction enzyme are the tools of recombinant DNA technology.
A bacterial gene never holds a target plasmid, while a bacterial plasmid always holds a target gene inside it.
Therefore, the option that best describes Recombinant DNA is a bacterial plasmid with a target gene inside it. Thus, the correct option is A.

name the main nitrogen-containing compound found both in plants and in animals
Answer:
Soil contains nitrifying bacteria that are crucial in converting nitrogenous wastes of dead and decaying matter of plants and animals to ammonia.
The most redox potential of soil nitrogen, ammonia, is transformed into its most oxidized form, nitrate, by nitrifying bacteria. By preventing soil nitrogen losses from leaching and nitrate denitrification, this is crucial for the function of the soil ecosystem.
What nitrogen compound found in plants and animals?The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals. The ammonia is subsequently changed into compounds that include ammonium. This is how the formation of ammonium compounds is aided by animals and plants.
Nitrification, which turns ammonia into nitrite and then nitrate, is a vital stage in the worldwide nitrogen cycle. Only prokaryotes perform aerobic nitrification, which makes up the majority of the process.
Therefore, The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals.

Does Europe have a rainforests? Please select the best answer from the choices provided OT O Mark this and return Save and Exit )
Answer:
While Europe has no Tropical Rainforests, which are what most people immediately think of when they hear the term, it contains several Temperate Rainforests, most notably in Northern England, Scandanavian countries, and the Colchis Rainforest in Bulgaria, Turkey, and Hungary.
Explanation:
So yes, Europe has rainforests.
There are two types of rainforests in the world, temperate and tropical rainforests. Europe has temperate rainforests -not tropical-.
Rainforests
The rainforest ecosystems can be classified according to various criteria such as latitude, temperature, humidity, seasonality, and altitude.
There are two types of rainforest in the world
Tropical rainforest ⇒ The Amazonian, for instanceTemperate rainforest
Temperate rainforest
They are found in areas with cool and milder temperatures, with moderate to high humidity levels and temperatures ranging between 10º and 21º C.
Since rainfalls are not as abundant as in tropical rainforests, vegetation is not as exuberant.
Vegetal coverage is very high and arranged in many different strata.
Vegetation is dominated by phanerophytes and epiphytes. These are evergreen plants with leathery leaf types, medium to small in size.

Most chemical reactions within cells do not occur spontaneously. Instead, they need a catalyst to get them started. Why do you think this is so?
Answer:
A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst.
