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...

What is transportation in plant.

Biology - Transportation in Plants

Introduction

  • The plants have low energy needs, as they use relatively slow transport systems.

  • Plant transport systems move energy from leaves and raw materials from roots to all their parts.

  • The xylem (tissue) moves water and minerals obtained from the soil to all other parts of the plants.

  • The phloem (tissue) transports products of photosynthesis from the leaves (where they are synthesized) to other parts of the plant.

Movement of Water in Plants

  • Water moves into the root from the soil and then steady it moves into the root xylem, creating a column of water, which is progressively pushed upwards.

Movement of Water Plants

  • Evaporation of water molecules from the cells of a leaf (see the image given above) creates a suction process, which pulls water from the xylem cells of roots; this process keeps going on.

  • The loss of water in the form of vapor from the leaves (i.e. aerial parts) of the plant is known as transpiration.

  • Transpiration, likewise, helps in the absorption and upward movement of water and minerals dissolved in it from roots to the leaves.

  • Transpiration also helps in the temperature regulation (in plants).

  • The transport of soluble products of photosynthesis is known as translocation, which occurs in the part of the vascular tissue known as phloem.

  • Along with photosynthesis products, the phloem also transports amino acids and other substances, which are ultimately delivered to roots, fruits, seeds, and to growing organs.

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...

Elon musk new mission in helping nature

Your friend
SpaceX is embarking on a bold new adventure: making rocket fuel out of thin air. "SpaceX is starting a program to take CO2 out of atmosphere & turn it into rocket fuel," CEO Elon Musk tweeted on Monday. "Please join if interested." Such a process — using in-situ resources to generate fuel — could have great implications during our transition to becoming interplanetary, according to Musk. "Will also be important for Mars," he added in a follow-up tweet. Carbon Appetit It's particularly a pertinent topic for SpaceX's operations, given that its workhorse Falcon 9 rocket emits plenty of CO2 when it launches. And it's not quite as far fetched as it sounds. Using a new technique called "direct air capture" (DAC), SpaceX could suck in thousands of tons of carbon dioxide to turn it into a source of fuel, Bloomberg reports. Iceland recently started operations at the world's largest DAC plant, sucking up to 4,400 tons of CO2...

Acid, bases and salt.

Your friend
Chemistry - Acids, Bases, and Salts Introduction We taste food sour and bitter, it is only because of presence of acids and bases respectively. Litmus Solution Litmus, which is extracted from lichen, has purple color (see the image given below), but the condition is when it is neither acidic nor basic, i.e. neutral. Litmus basically is a plant belongs to Thallophyta, and in chemical experiment, it is commonly used as an indicator. The substances, which odor changes in acidic or basic media, are known as  olfactory  indicators. Acid or Base in a Water Solution The hydrogen ions in HCl are produced because of the presence of water. Secondly, the separation of H +  ion from the HCl molecules cannot be done in the absence of water. The chemical formula is illustrated below HCl + H 2 O → H 3 O +  + Cl – Furthermore, hydrogen ions cannot exist alone, but they can exist in presence of water molecules. Therefore, hydrogen ions are shown as H + (aq) or hydronium i...
