why the cell is called Functional unit of life |
|
Answer» Cell is called as the building unit of body .Because cell is the making unit of tissues .tissues are formed organs .so cell is the fundamental unit of life Cell building block of material. It is functional unit of life becausesame kind of cells make tissue. Two or more different kind of tissue make organ. Many ogana are joined together to form organism. Cell is called functional unit of life because many cell join together to make tissue. Many tissue combine together to form organs. Many organs are joined together to form body. |

Functions of villi |
|
Answer» The small intestine has many tiny finger like projections called villi. These villi increase the surface area for absorption of food. It increases the suface suface area for abosoring the digested food. The small intestine has millions of tiny finger-like projections called villi . These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body. The small intestine has millions of tiny finger-like projections called villi . These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body. The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions |

What is the difference between ionic bond and covalent bond |
|
Answer» Ionic means giving an electron completely nd covelent means sharing of electrons Bonds form by transfer of electron from one metal to another non metal is called ionic bond Bonds formed by sharing of an electron is called covalent bond IONIC COMPOUND = THIS TYPE OF COMPOUND FORMED BY TRANSFER OF ELECTRONE FROM METALS TO NON- METALS. EX- NACL COVALENT BOND = THIS TYPE OF BOND FORMED BY SHARING OF ELECTRONS. EX- CARBON COMPOUND IS EXAMPLE OF COVALENT COMPOUND. THANKS - PRITHVIRAJ GODARA (SCIENCE TEACHER ) Ionic bond is formed by transferring of electron but covalent bond is formed by sharing of electron. Ionic bond includes gaining or losing of electron to gain positive or negative charge. Covalent bond is the sharing of electron, In Covalnet bond tlno charge is obtained. |

What can be seen when a strip of copper metal is placed in a solution of silver nitrate |
|
Answer» Cooper lies above silver in the reactivity series. So, it will displace silver from it\'s salt solution and hence form copper nitrate and silver metal. Answer:When a \'strip of copper metal\' is placed\xa0in a \'silver nitrate\'\xa0solution, a greyish white deposit ofsilver can be seen\xa0of thecopper strip. EXPLANATION: This happens because \'copper\' is more reactive than \'silver\' and displaces\xa0silvereasily to form\xa0copper nitrate. |
