Structure of flower |
| Answer» \tCorolla: It is the most colorful and bright part of the flower which attracts humans and pollinators. In general, it is thin and soft in structure. Multiple numbers of petals are there in a single flower having the same kind of color and texture. They protect the pistil and stamen of a flower.\tCalyx: It is the outermost whorl of the flower. It is usually made up of sepals which are commonly green and have leaf-like structure. It gives support to the petals and protects the bud before opening.\tAndroecium: The next important whorl is androecium that includes stamens. Stamen is the male reproductive part of a flower that is made up of anther and filament. A filament is a long stalk that contains anther at the top. Anther produces pollen which is considered as the male reproductive cell. The number of filaments is equal to the number of petals in a flower.\tGynoecium: It is the innermost whorl, that includes the female reproductive part of the flower, mainly carpels. Carpel can be divided into three sections:\tStigma: The top most part of the carpel has a platform like structure called as the stigma. It is a sticky portion where pollen grains fall, attach to the surface and germinate.\tOvary: The bottom part of the carpel is an ovary. It contains ovules in it. It also contains seeds which turn into fruit after the fertilization process.\tStyle: The connecting part of the stigma and the ovary is style. It is the female part of the flower, and it has a long tube-like structure. | |

Deplication of ozone layer & global warming |
| Answer» Ozone layer depletion is one of the most serious problems faced by our planet earth. It is also one of the prime reasons which are leading to global warming. Ozone is a colourless gas which is found in the stratosphere of our upper atmosphere. The layer of ozone gas is what which protects us from the harmful ultraviolet radiations of the sun. The ozone layer absorbs these harmful radiations and thus prevents these rays from entering the earth’s atmosphere. Ultraviolet radiations are high energy electromagnetic waves emitted by the sun which if enters the earth’s atmosphere can lead to various environmental issues including global warming, and also a number of health related issues for all living organisms. Thanks to the ozone layer which protects us from these harmful rays.Global warming, the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Climate scientists have since the mid-20th century gathered detailed observations of various weather phenomena (such as temperatures, precipitation, and storms) and of related influences on climate (such as ocean currents and the atmosphere’s chemical composition). These data indicate that Earth’s climate has changed over almost every conceivable timescale since the beginning of geologic time and that the influence of human activities since at least the beginning of the Industrial Revolution has been deeply woven into the very fabric of climate change. | |

What do yu mean by stellar evolution.....? |
|
Answer» Stellar evolution is the process by which a star changes over the course of time. Depending on the mass of the stars, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the age of universe. Stellar evolution is the process in which the forces of pressure (gravity) alter the star. With these forces acting upon stars, their characteristics change dramatically over the period of their existence. |

What is feedback mechanism?? |
| Answer» Feedback mechanism is the mechanism of the body to maintain the levels of hormones in the body in the desired limits. An increase or decrease in the levels of the hormones triggers the feedback mechanism.\xa0The body has two types of feedback mechanisms, positive and negative feedback mechanism.Example:Negative feedback mechanism:\xa0Whenever there is a change in the normal state, the messages are sent to ‘increase’ secretions if there is a fall below normal or to ‘decrease’ secretions if there is a rise above normal to restore the normal body state. Such a mechanism is called a negative feedback mechanism.The increase in the blood sugar level stimulates the secretion of insulin so that the sugar level is maintained. If the blood sugar level falls below normal, then it stimulates the secretion of glucagon. Glucagon stimulates the breakdown of glycogen to glucose, and thus, the normal sugar level is maintained. | |

What is D. N. A |
|
Answer» They are basically a genetic code present in the chromosome of human beings, which are responsible for the transfer of hereditary character from one generation to other. DNA is double helical structure it\'s the main function is to transfer genetic information from one generation to another generation DNA (abbreviated as Deoxyribonucleic acid) is a molecule that is responsible for carrying the hereditary materials or the genetic instructions that are required for the development and growth of all life on earth. This is also true for viruses as most of these entities have either RNA or DNA as their genetic material.DNA is found in all living organisms and is mainly responsible for the inheritance of human beings. The cells of the human body possess the same DNA which is located in the nucleus of cells. Hence, it is described as nuclear DNA. The DNA present in the mitochondria of the cell is termed as mitochondrial DNA which is inherited from the mother to the child. In humans, there are approximately 16,000 base pairs of mitochondrial DNA. Dna (deoxyribo nucleic acid ) is agenetic material which contain information of one protien. Hope it will help u.

What is refractive index ? How it\'s Calculated |
|
Answer» A ray of light changes its direction when it enters from one medium to another medium. This happens because speed of light is different in different media. For example; the speed of light is 3 x 108 m/s (2.99x108 m/s) in vacuum and it is 2.98 x 108 m/s in air.Refractive Index is the extent of change of direction of light in a given pair of media. The refractive index is a relative value of speed of light in the given pair of media. Thus, to calculate the refractive Index the speed of light in two media is taken. It is a physical quantity.the relative speed of propagation of light in different media. |
