What is mensuration ? It always confuse me. Please don\'t ignore mee |
|
Answer» Meghna this is experienced by you also. Hi meghna Since the ovary of female release one egg every month, therefore, the uterus also prepares every month to receive a fertilised egg. The inner lining of the uterus becomes soft and thick with lots of blood capillaries in it. This preparation is necessary as in case the egg is fertilised by the sperm, it helps to keep the egg and nourish it. If however, the egg is not fertilised, then the thick lining of the uterus is not required and the uterus lining breaks down and comes out through the ****** in the form of blood and mucous. This is called menstruation.(b) Menstruation cycle in females:(i) When a girl reaches puberty at the age of 10 – 12 years, the *** hormones released it her blood cause some of the ova in the ovaries to become mature.(ii) Usually one mature egg is released from the ovary into the oviduct once every 28 days. This is called ovulation.(iii) Before ovulation, the inner lining of the uterus becomes thick and spongy, and full of blood capillaries, and prepares itself to receive the fertilised egg.(iv) If the ovum does not get fertilised, then the thick and soft inner lining of the uterus is no longer needed and hence it breaks and the dead ovum comes out from ****** in the form of bleeding called menstruation.(v) Menstruation usually occurs 14 days after ovulation and usually lasts for 3 to 5 days.(vi) After menstruation is over, the inner lining of the uterus starts building up again so that it becomes ready to receive the next ovum in case it gets fertilised.(vii) If the ovum does not get fertilised even now, then the menstruation takes place again and this cycle goes on repeating. |

1.Explain magnetic field due to current through A) A straight conductorB) A circular loop |
| Answer» \tMagnetic Field due to a Current carrying Conductor:Magnetic Field due to a Straight Current-carrying Conductor:The magnetic field lines around a straight conductor carrying a current are concentric circles.\xa0The direction of a magnetic field is given by the Right-Hand Thumb Rule.\xa0Right-Hand Thumb Rule:Imagine that you are holding a straight current-carrying conductor in your right hand such that the thumb points towards the direction of the current. Then, your curved fingers wrapped around the conductor point in the direction of the field lines of the magnetic field.The magnitude of the magnetic field due to a straight current-carrying conductor at a given point is\tDirectly proportional to the current flowing through the conductor.\tInversely proportional to the distance of that point from the conductor.\xa0Magnetic Field due to a Current-carrying Circular Coil:\xa0\tThe magnetic field lines near the coil are nearly circular or concentric.\tThe magnetic field at the centre of the coil is maximum and almost uniform.\tLooking at the face of a coil, if the current around it is in the clockwise direction, then it faces the South Pole. If the current around it is in the anticlockwise direction, then it faces the North Pole. This is called the Clock rule.\tThe magnitude of a magnetic field at the centre of the coil is\tDirectly proportional to the current flowing through it\tInversely proportional to the radius of the coil\tDirectly proportional to the number of turns of the coil\xa0Magnetic Field due to a Current-carrying Solenoid:Solenoid is a long coil containing a large number of close turns of insulated copper wire. The magnetic field produced by passing the current through the coil. Magnetic field produced by the solenoid is similar to the magnetic field produced by the bar magnet. The magnetic field lines in the solenoid are parallel.The magnetic field inside a solenoid is uniform.In accordance with the Clock rule, the end of the solenoid at which the current flows in the anticlockwise direction behaves as a North Pole, while the end at which the current flows in the clockwise direction behaves as a South Pole.The magnitude of the magnetic field inside the solenoid is directly proportional to the\tCurrent flowing through it \tNumber of turns per unit length of the solenoid\xa0 | |

Working of human brain. |
|
Answer» our brain contains billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation. A complicated highway system of nerves connects your brain to the rest of your body, so communication can occur in split seconds. Think about how fast you pull your hand back from a hot stove. While all the parts of your brain work together, each part is responsible for a specific function — controlling everything from your heart rate to your mood.The cerebrum is the largest part of your brain. It\'s what you probably visualize when you think of brains in general. The outermost layer of the cerebrum is the cerebral cortex, the "gray matter" of the brain. Deep folds and wrinkles in the brain increase the surface area of the gray matter, so more information can be processed.The cerebrum is divided into two halves (hemispheres) by a deep fissure. The hemispheres communicate with each other through a thick tract of nerves, called the corpus callosum, at the base of the fissure. In fact, messages to and from one side of the body are usually handled by the opposite side of the brain.\xa0brain\'s hemispheres are divided into four lobes.The frontal lobes\xa0control thinking, planning, organizing, problem solving, short-term memory and movement.The parietal lobes\xa0interpret sensory information, such as taste, temperature and touch.The occipital lobes\xa0process images from your eyes and link that information with images stored in memory.The temporal lobes\xa0process information from your senses of smell, taste and sound. They also play a role in memory storageThe cerebellum is a wrinkled ball of tissue below and behind the rest of your brain. It works to combine sensory information from the eyes, ears and muscles to help coordinate movement.The brainstem links the brain to the spinal cord. It controls many functions vital to life, such as heart rate, blood pressure and breathing. This area is also important for sleep.Structures deep within the brain control emotions and memories. Known as the limbic system, these structures come in pairs. Each part of this system is duplicated in the opposite half of the brain.The thalamus\xa0acts as a gatekeeper for messages passed between the spinal cord and the cerebral hemispheres.The hypothalamus\xa0controls emotions. It also regulates your body\'s temperature and controls crucial urges — such as eating or sleeping.The hippocampus\xa0sends memories to be stored in appropriate sections of the cerebrum and then recalls them when necessary.The peripheral nervous system is all the nerves in your body, aside from the ones in your brain and spinal cord. It acts as a communication relay between your brain and your extremities. For example, if you touch a hot stove, the pain signals travel from your finger to your brain in a split second. In just as short a time, your brain tells the muscles in your arm and hand to snatch your finger off the hot stove.Nerve cells (neurons) have two main types of branches coming off their cell bodies. Dendrites receive incoming messages from other nerve cells. Axons carry outgoing signals from the cell body to other cells — such as a nearby neuron or muscle cell.Interconnected with each other, neurons are able to provide efficient, lightning-fast communication.\xa0nerve cell (neuron) communicates with other cells through electrical impulses when the nerve cell is stimulated. Within a neuron, the impulse moves to the tip of an axon and causes the release of neurotransmitters, chemicals that act as messengers.Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell. This process repeats from neuron to neuron, as the impulse travels to its destination — a web of communication that allows you to move, think, feel and communicate.I hope you understand this ????????

Yeast is used in making bread and bear in beverage industry.why? |
| Answer» This is the reasonCarbon dioxide is what gives alcoholic beverages such as beer and champagne their characteristic bubbles and is also responsible for\xa0rising bread. As yeast begins to metabolize sugars in bread dough, the carbon dioxide gas is trapped within the gluten strands, creating bubbles and causing a\xa0leavening action. In beverages, the carbon dioxide is trapped within the liquid by the pressure of the sealed container. When the container is opened, the pressure is released and the carbon dioxide begins to release\xa0via a bubble.Alcohol, the other byproduct of yeast fermentation, is also produced during the bread making process\xa0but evaporates as the bread bakes. When making alcoholic beverages, yeast is allowed to ferment for a much longer period of time, causing it to produce more alcohol. | |

Write the functions of male and female gonads. In points |
| Answer» The male gonad is the\xa0the testis or\xa0testicle. It is located behind the ***** in a pouch of skin called *******. The testes produce and store sperm, and they are also the body\'s main source of male hormones (testosterone). These hormones control the development of the reproductive organs and other male characteristics, such as body and facial hair, low voice, and wide shoulders.The female gonad is the ovary. It\xa0is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus.\xa0The ovaries have two functions: they produce eggs (ova) and female hormones. Each month, during the menstrual cycle, an egg is released from one ovary. The ovaries are the main source of female hormones (estrogen and progesterone). These hormones control the development of female body characteristics, such as the breasts, body shape, and body hair. They also regulate the menstrual cycle and pregnancy. | |
