Write basic life process and its functions? |
|
Answer» Life processes – The processes that are necessary for an organism to stay alive. Eg. Nutrition,respiration, etc.Nutrition- The process in which an organism takes in food, utilizes it to get energy, for growth, repair and maintenance, etc. and excretes the waste materials from the bodyTransportationTransportation and transportation system in plants and animals are entirely different. In animals, transportation is carried out through the circulatory system. This system includes the heart, blood, and blood carrying blood vessels.MetabolismMetabolism is the chemical process in which different types of chemical reactions involved in controlling the living state of the cells in an organism. It is broadly classified into catabolism and anabolism.RespirationRespiration includes the exchange of gases as well as the burning of food. Animals have a well defined respiratory system for respiration.ReproductionThe biological process of reproducing their own offspring determines the continuity of species, generation after generation. The basic types of reproduction are sexual and asexual reproduction.ExcretionElimination of toxic waste substances from the body is called excretion. There are various modes of\xa0excretion and it generally differs with the different types of living species. Nutrition,respiration,transportation,excretion,reproduction,etc BASIC LIFE PROCESS ARE:----- |

Describe the process of urine formation in kidney? |
|
Answer» The mechanism of urine formation takes place in following steps-(i) Ultrafiltration- All the blood components are filtered by the kidneys except for the blood cells and the plasma proteins, e.g. urea, water, sodium, glucose, potassium,etc.(ii) Selective reabsorption- The essential components are reabsorbed back into the blood vessels, e.g. glucose, water, sodium, etc.(iii) Secretion- The movement of elements such as water, glucose, amino acids, urea etc from the blood into the nephron is known as secretion. For example,\xa0potassium ions and hydrogen ions are secreted by distalconvoluted tubule (DCT) and uric acid and other toxic chemicals secreted by proximal convoluted tubule (PCT)iv) Then the water reabsorption content is further regulated before coming out of the kidney through a hormone, anti-diuretic hormone (ADH).(v) Urine is then formed, collected in the bladder and excreted outside the body. Urine is formed in the kidneys by the nephrons... |

What is SI unit of potential difference |
|
Answer» SI unit of electric potential difference is Volt (V) Volt(V) Potential difference is nothing but voltage and is measured by a device called Voltmeter. It is always connected in parallel across the points whose potential difference is to be measured.\tSI unit of electric potential difference is Volt (V).\tSI unit of Work done is Joule (J).1 V = 1 J/ 1 C, potential difference is 1 when 1 joule work is done to move 1 coulomb of charge from one point to another Volt |

Difference between tropic movement and nastic movement. |
| Answer» Nastic movements→ Nastic movements are non directional responses to stimuli such as temperature and heat.→ The most important feature of this type of movement is that movements are not governed by the direction of the stimulus.→ They may be induced by touch (seismonastic), temperature (Thermonastic), light, and chemicals.→ Whatever be the direction of stimulus, the movements always occur in a particular direction without reference to the direction of the stimulus→ Example of seismonastic movement is movement of Venus fly trap. Tropic movement→ Tropic movement is the response to stimuli that comes from one direction.→ It is a directional movement.→ If the movement of the plant part is towards the stimulus, then it is known as positive tropism . If the movement of the plant part is away from the stimulus, then it is known as negative tropism .→ For example phototropism, Geotropism etc.Tropisms and nastic movements are both plant responses to external stimuli. however tropisms are depend on the direction of the stimulus nastic movements do not depend on the direction of a stimulus | |

What are balanced force |
|
Answer» A force where two forces of equal size, act on a body, in opposing directions is known as a Balanced Force. In Balanced Force, a body continues to be in its position i.e. it may be continuously moving with the same speed and in the same direction or it may be still in its position.Suppose you are pushing a wall and as expected, the wall does not move and neither do you. It means that you and the wall are exerting a balanced force on each other. If resultantant force applied on an object is zero then it is called balanced force. |

What do you mean by emulsification of fat? where does it take place? |
| Answer» Emulsification is the process which involve breakdown of large fat globules in to smaller globules which are soluble in water.It takes place in the gut by the action of bile juice which are produced in the liver. It is important to emulsify fat as if it is not emulsified it will be very difficult for the enzyme lipases do cat on it in order to digest them.It increases the efficiency of enzyme which are acting on it and braking down fat molecules in to fatty acid and glycerol which can be easily digested or can be absorbed by the small intestine.The digestive enzyme called as lipase is a water soluble enzyme which act mainly on the surface of fat globules and help in fat digestion. | |

Why reflex arcs are neede |
|
Answer» Nerves from all over the body meet in a bundle in the spinal cord on their way to the brain. Reflex arcs are formed in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain. Reflex arcs are needed for quick responses. It is needed to show the pathway of reflex action... It help to transfer message and react on it |

Difference between electric potential and electric potential energy |
| Answer» Electric potential is the work done per unit charge in bringing the charge from infinity to that point against electrostatic force.In a conductor, electrons flow only when there is a difference in electric pressure at its ends. This is also called potential difference. In a circuit, this potential difference is created by a battery. | |
| 50944. |
Define the term static electricity and current electricity |
|
Answer» Static electricity means charge remains at rest and current electricity means charge at motion. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity. |

What is the role of light in photosynthesis |
|
Answer» The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata. I think inna bhut hai ok vansh Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant. |
