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.

explain the element silver

Your friend
Chemistry - Silver Introduction Silver is a soft, lustrous transition, and white metal. Silver has the highest electrical and thermal conductivity; and, it has also the highest reflectivity of any metal. The symbol of silver is  ‘Ag’  and atomic number is  ’47.’ Salient Features of Silver Silver is a precious metal used since long time by human beings. Silver is an element of group 11 of the periodic table. Silver has an excellent white metallic luster commonly used in a high polish. As silver has no color; therefore, it has high reflectivity (of light). Silver has very high electrical and thermal conductivity. Its electric conductivity is the highest – higher than copper. Among all the metals, silver also has the lowest contact resistance. Occurrence of Silver The metal silver is usually found in the Earth's crust in the pure form. Silver also found as an alloy with the gold and some other metals. Silver is also found in some minerals, such as argentite and chlorargyrite...

explain the element iron

Your friend
Chemistry - Iron Introduction Iron is the most common element found in largely in outer as well inner core of the earth. The symbol of iron is  ‘Fe’  and atomic number is  ‘26.’ Iron is one of the earliest known elements that is being used by human beings. Salient Features of Iron Following are the major features of iron − Pure iron element is soft, ductile, and malleable. The boiling point of iron ranges between 1533 0 C and 2450 0 C. Iron easily gets attracted towards magnet. In dry air, iron remains inactive and does not react (with air); however, in moist air, it reacts and forms rust. Pure iron normally does not react with pure water; however, it reacts easily with ordinary of polluted water and rust forms. Iron reacts with halogen and Sulphur to form halide and sulphide accordingly. Occurrence of Iron The inner and outer cores of the earth are largely made up of iron and nickel. Most likely, iron is the most abundantly available element of the earth; however, it is ...

what is gravity

Your friend
Physics - Gravitation Introduction All celestial bodies those found in the universe attract each other and the force of attraction among these bodies is called as the  gravitational force . Universal Law of Gravitation Every object in the universe has the property to attract every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them (see the image given below). F  = force of attraction between two the objects ‘A’ & ‘B’ M  = mass of ‘A’ m  = mass of ‘B’ d 2  = the square of the distance between ‘A’ & ‘B’ G  = is the constant of proportionality and is known as the universal gravitation constant. The SI unit of G is  N m 2  kg –2 . It is obtained by substituting the units of force, distance and mass (as given in the following equation − $$G = \frac{Fd^2}{M \times m}$$ Henry Cavendish had calculated the value of  ‘G’  as  6.6...
