How does Messi keep the ball close to himself

Your friend
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 - Vertebrata



Introduction

The organisms of this kingdom have a true vertebral column and the internal skeleton structure.

Classification of Vertebrata

  • Vertebrates are further classified as −

    • Pisces

    • Amphibia

    • Reptiliai

    • Aves

    • Mammalia

  • Let’s discuss each of them in brief −

Pisces

  • The organisms of this group are typically different types of fishes.

  • Fishes can live only in water.

  • The skin fish is covered with scales/plates.

  • Fish use oxygen dissolved in water by using gills

The tail of fish helps in their movements.

  • Fishes are cold-blooded organisms and their hearts have only two chambers.

  • Fishes lay eggs.

Amphibia

  • The organisms of amphibia have mucus glands in the skin, and they have three-chambered heart.

  • Amphibian can live in water as well as on land.




  • The organisms of amphibian respire through either gills or lungs.

  • The organisms of amphibia lay eggs.

Reptilia

  • The organisms of this group are cold bolded.

  • The organisms of reptilia lay eggs with tough coverings.

Aves

  • The organisms of Aves group are warm-blooded.

  • The organisms of Aves group lay eggs except a few, such as bat.

Most of the Aves have feathers.

Mammalia

oh no am a mammal


  • The organisms of Mammalia group are warm-blooded and they have four-chambered hearts.

  • Mammalia are typically characterized for their mammary glands.

  • Mammary glands produce milk to nourish the young one.

  • Most of the mammals produce live baby; however, a few of mammals, such as, the platypus and the echidna lay eggs.

Mammals’ skin has hairs along with sweat and oil glands.

Bill gates makes strange toilets

Your friend
Watch the Throne At long last, the successor to the porcelain throne has arrived. Well, maybe. The project began in 2011, when the Bill and Melinda Gates Foundation issued the "Reinvent the Toilet Challenge." Samsung and the Gates Foundation joined up in 2019 to create the new product, which doesn't use a typical sewage system. Instead, according to a Samsung blurb about the toilet, it recycles pee through a purification process — while solid waste is dehydrated, dried, and "combusted into ashes." And they say only Apple comes up with the cool hardware! Clean Water It doesn't sound like serious stuff, but waste disposal is a significant global issue. The United Nations says that 2 billion people lack access to safe drinking water services, and 3.6 billion lack safe sanitation services. And if that's not enough, more than 700 children under the age of five die every day from diarrheal diseases because of unsafe water and sanitation conditions....

How can I classify living Organism

Your friend
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 org...

understanding Coal and petroleum-Chemistry

Your friend
Chemistry - Coal and Petroleum Introduction The resources, which are present in unlimited quantity in nature and are not likely to be exhausted by human activities, are known as  Inexhaustible Natural Resources . E.g. sunlight, air. The resources, which are present in limited quantity in nature and are likely to be exhausted by human activities, are known as  Exhaustible Natural Resources . E.g. forests, wildlife, minerals, coal, petroleum, natural gas etc. Exhaustible natural resources were formed from the dead remains of living organisms (fossils); therefore, these natural resources are also known as  fossil fuels . E.g. coal, petroleum and natural gas. Coal Coal is hard as stone and black in color. Coal is one of the fuels used to cook food. Coal is used in thermal power plants to produce electricity. Under high pressure and high temperature, the dead plants those got buried inside the Earth, got slowly converted into coal. Coal contains mainly ...
