Animal tissues |
| Answer» The animal cells are grouped together to form animal tissues.\xa0These tissues vary in their structure, function, and origin.The animal tissues are divided into epithelial, connective, muscular and nervous tissues.\xa0\xa0Animal tissues are of four types, viz. epithelial tissue, connective tissue, muscular tissue and nervous tissue.Epithelial Tissue:The epithelial tissue forms the covering or lining of most of the organs. The cells of epithelial tissue are tightly packed and form a continuous sheet. There is small amount of cementing materials between the cells and no intercellular space is present. Permeability of the epithelial tissue plays a great role in exchange of materials among various organs it also plays an important role in osmoregulation. All epithelial tissues are separated by the underlying tissue by an extracellular fibrous basement membrane.\xa0Connective Tissue:The cells of a connective tissue are loosely scattered in a matrix. The matrix can be a fluid, jelly like, dense or rigid. The nature of matrix depends on the function a connective tissue serves.Muscular Tissue:Muscular tissue is composed of muscle cells. Muscle cells are specialized cells which have the capability to contract and expand. Due to contraction and expansion, muscles facilitate various kinds of movements in the body. | |

What are atoms ....defination please |
|
Answer» An\xa0atom\xa0is the smallest constituent unit of ordinary\xa0matter\xa0that constitutes a\xa0chemical element. Every\xa0solid,\xa0liquid,\xa0gas, and\xa0plasma\xa0is composed of neutral or\xa0ionized\xa0atoms. Atoms are extremely small, typically around 100\xa0picometers\xa0across. They are so small that accurately predicting their behavior using\xa0classical physics\xa0– as if they were\xa0billiard balls, for example\xa0– is not possible due to\xa0quantum effects. Current atomic models use\xa0quantum principles\xa0to better explain and predict this behavior. Atoms are defined as\xa0“the basic building blocks of matter”.It is the smallest constituent unit of matter that posses the properties of the chemical element. Atoms don’t exist independently, instead, they form ions and molecules which further combine in large numbers to form matter that we see, feel and touch.Atoms are much too small to be seen; hence experiments to find out their structure and behavior have to be conducted with large numbers of them.\xa0From the results of these experiments we may attempt to construct a hypothetical model of an atom that behaves like the true atom. The spreading of fragrance of incense stick from a corner to the whole room indicates that particles of matter keep moving from higher to lower concentration. Atoms is the smallest components of an element, characterized by a sharing of the chemical properties of the elements and a nucleus with neutrons protons and electrons. |

|
Answer» Average velocity would be equal to average speed when the total\xa0distance\xa0travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction. A n s w e r :Average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction. Speed is a scalar quantity having only magnitude and no direction while velocity is a vector quantity having magnitude and direction both.The magnitude of average velocity of an object equal to its average speed when the motion of the object will be straight and unidirectional.As, speed is scalar quantity and velocity is a vector quantity, so the object is required to move in straight line with same or constant direction. |

What are the function of rough endoplasmic reticulum |
|
Answer» The RER helps in protein synthesis as it has ribosomes on its surface The function of the rough endoplasmic reticulum (ER) is to produce a fully-functioning protein.Ribosomes residing on the endoplasmic reticulum give it a non-smooth appearance, hence the name Rough ER.These fully-functioning proteins are the working molecules within every cell that perform most all functional work. Fully-functioning proteins repair muscles, lubricate your brain, provide communication between cells, perform liver function,EVERYTHING!!!\xa0They do this by using the common energy currency in the cell, ATP.This is one of the major advantages that complex cellular species (eukaryotes, including plants, fungi, animals, humans) have. They have the full complex protein manufacturing factory (rough ER, Golgi apparatus, supporting proteins). Bacteria do not have this rough ER, and hence are not equipped with the full protein factory that complex species have.Fully-functioning proteins can be used inside the cell for its own operation and maintenance AND can also be packaged for transportation out of the cell for use elsewhere.The steps to making a protein are transcription, translation, and complex folding. All living cells, including bacteria can perform transcription and translation, but only eukaryotic cells can perform the complex folding function. Transcription is the cellular process of making a messenger RNA (mRNA) from the DNA and the subsequent transportation of it out of the nuclear envelope. Translation is the cellular process of making an animo acid chain from the mRNA.\xa0Translation occurs on the Rough ER. Complex folding continues in the Golgi apparatus.The surface of the Rough ER is studded with ribosomes. These ribosomes perform the work of the translation of the mRNA into an amino acid chain. The Rough ER is typically located near, and continuous with, the outer layer of the nuclear envelope, utilizing large double membrane sheets that overlap onto each other. (The Golgi apparatus does not have a continuous membrane with the Rough ER; the started amino acid chains are transported from the Rough ER to the Golgi with little membrane-enclosed transportation pods, called vesicles. Also, the Rough ER continually works with the Golgi apparatus in the production of these fully-functioning proteins, including the marking of its target location and its packaging.)Ribosomes are a very primal molecular motor, originating from an RNA World. But these ribosomes perform their work very efficiently and all life forms use ribosomes to manufacture proteins. The development of complicated molecular machinery to form fully-functioning, complex, packaged proteins is one of the enablers that allowed the development of the eukaryotic cell and all subsequent, complex life. The development of the eukaryotic cell from bacteria is an active area of investigation by scientists at the current time. Exciting stuff, indeed!!! The rough endoplasmic reticulum consists of ribosomes(synthesised by nucleolus). The main function of ribosomes is synthesis of proteins. Therefore the rough endoplasmic reticulum are associated with synthesis of proteins for intracellular activities like membrane biogenesis Function of roigh endoplasmic reticulum is tge formation of protien or protien synthesis It\'s function is to produce proteins for the rest of the cell to function |
