How does Messi keep the ball close to himself

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 - Hormones in Animal

Introduction

  • Human body has different glands (as shown in the image given below) that secret Hormones (liquid substance), which are essential for the different body functions.

Endocrine Glands

  • Adrenaline Hormone is secreted from the adrenal glands. It is secreted directly into the blood and then carried to different parts of the body.

  • On the other hand, plants have hormones that control and regulate their directional growth.

  • Iodine is essential for the thyroid gland that makes thyroxin hormone.

  • Further, Iodine is an essential element for the synthesis of thyroxin.

  • Deficiency of Iodine, that might cause goiter.

  • The term “goiter” refers to the abnormal expansion of the thyroid gland (resulting into swollen neck).

  • Thyroxin Hormone regulates carbohydrate, protein, and fat metabolism in the body and provide the best balance for body growth.

  • Growth hormone, which is secreted by the pituitary gland, regulates growth and development of the body.

  • The deficiency of growth hormone in childhood causes dwarfism short height.

  • During the age of 10-12, there are certain physical change in the bodies of children, which is caused by the secretion of testosterone in boys and oestrogen in girls.

  • As shown in the image given above, it is significant difference between male and female body i.e. males have testis (secretes Testosterone Hormone) and females have ovary (secretes Oestrogen Hormone).

  • Insulin is a hormone, which is produced by the pancreas and helps in regulating the sugar levels of blood.

  • If insulin is not secreted in proper amounts or on a proper time, the sugar level in the blood rises, which may cause different harmful effects in the body.

explain the element copper

Your friend
Chemistry - Copper Introduction Copper is a soft, ductile, and malleable metal. Copper has very high thermal and electrical conductivity. The symbol of copper is  ‘Cu’  and atomic number is  ’29.’ Copper is known to people since (about) c. 8000 BC. Copper is the first metal, which was smelted from its ore around c. 5000 BC. Salient Features of Copper Copper was the first metal that cast into a shape (in a mold). Copper was the first metal that successful alloyed with another metal, e.g. copper alloyed with tin and resultantly bronze is prepared. It is done about c. 3500 BC. First metal to be purposefully alloyed with another metal, tin, to create bronze, c. 3500 BC. Copper has a natural reddish-orange color; it is visible once the its surface is exposed. Copper is a very good conductor of electricity and heat. Copper is an element of group 11 of the periodic table. Copper normally does not react with water; however, it does react slowly with atmospheric oxygen and form a ...

explain the element platinum

Your friend
Chemistry - Platinum Introduction Platinum is a malleable, ductile, dense, and highly unreactive chemical element. The symbol of platinum is  ‘Pt’  and its atomic number is  ‘78.’ The name of platinum is derived from a Spanish term i.e. ‘platina,’ which means " little silver ." Platinum is the most precious and the rarest metal (element) on the earth. Salient Features of Platinum Following are the important features of the platinum − Platinum is a silver white metal. Platinum is an element of group 10 of the periodic table. Platinum is one of the rarest elements in the crust of the earth. Platinum is one of the least reactive elements. Platinum has six natural isotopes. Platinum is one of the most highly valuable and precious metals. Platinum is characteristically resists corrosion in all conditions. Because of this reason, it is considered as noble metal. Platinum is normally insoluble in nitric and hydrochloric acid, but dissolves in hot  aqua regia . After dissolv...

How can I study for my chemistry Exam

Your friend
  how to study chemistry by science question and answers Chemistry is one of those subjects that you either enjoy or despise. Chemistry is usually not a required course in high school, but rather an elective. Most reputable universities, on the other hand, require all undergraduate students to take at least one chemistry course in order to graduate. If you want to work in medical, engineering, or a branch of natural science, you'll almost certainly have to take at least one chemistry course before graduating. For most people, chemistry is a difficult topic, but it doesn't have to be. Here are some tips I have for you to make you study and pass any chemistry exam.          1.     Before going to class, review and study the material . a student studying In a traditional learning approach, students come to class, the lecturer explains the content, elaborates on key concepts, assigns additional readings and assignments, and the session closes.
