The science of how Messi keeps the ball close to himself photo credit: ZaleDesigns Messi is a magician with the ball at his feet. He's in my opinion the best player in the sense that he can control the ball so well, runs so fast with the ball & changes the direction at full speed like it's a walk in the park. For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion. Height He is short which means a low center of gravity so it's difficult to push him off the ball. That's why we see that anyone rarely can topple him down, instead players much larger than him lose possession to him. So his short height suits his style of play & is a blessing in disguise. Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...
Biology - Diversity in Living Organisms
Introduction
Biodiversity term is used to define the diversity of life forms.
Biodiversity is a word more often used to refer to the variety of life forms found in a particular geographic region.
Diversity of life forms of a geographic region provides stability in the respective region.
Base of Classification
Greek thinker Aristotle first classified animals based on their place of residence whether they lived on land, in water, or in the air.
Later, all the living organisms are identified and categorized on the basis of their body design in form and function.
The idea of evolution was first described by Charles Darwin in 1859 in his book namely – The Origin of Species.’
Charles Darwin first described this idea of evolution in 1859 in his book, ‘The Origin of Species.’
Hierarchy of Classification Groups
Some biologists, namely Ernst Haeckel (1894), Robert Whittaker (1959), and Carl Woese (1977) have attempted to classify all living organisms into broad categories and named them ‘Kingdoms.’
Whittaker categorized into five kingdoms namely −
Monera
Protista
Fungi
Plantae
Animalia
Further, these kingdoms have been classification by naming the sub-groups at various levels as −
Let’s discuss each kingdom in brief −
Monera
The organisms of Monera kingdom do not have a defined nucleus or organelles, neither do any of them show multi-cellular body designs.
The examples of this monera kingdom are bacteria, anabaena, blue-green algae or cyanobacteria, and mycoplasma.
Protista
The organisms of Protista kingdom include many kinds of unicellular eukaryotic organisms.
The examples of Protista kingdom are algae, euglena, diatoms, and protozoans, etc.
Fungi
The organisms of fungi kingdom are heterotrophic eukaryotic organisms.
The organisms of this kingdom use decaying organic material as their food and therefore, they are also known as saprophytes.
Plantae
The organisms of this kingdom are multicellular eukaryotes with cell walls.
The organisms of plantae are autotrophs and they use chlorophyll for making their food (i.e. photosynthesis).
All plants are examples of plantae kingdom.
Animalia
The organisms of Animalia kingdom are all organisms which are multicellular eukaryotes without cell walls.
Organisms of Animalia kingdom are heterotrophs.
