What is neurotransmitters? |
| Answer» In 1921, an Austrian scientist named Otto Loewi discovered the first neurotransmitter by experimenting on frogs. Neurotransmitters are the chemicals which allow the transmission of signals from a neuron to a target cell across synapses. Neurotransmitters are packaged into synaptic vesicles and are released into and diffuse across the synaptic cleft, where they may be accepted by the next neuron at a specialized site called a receptor at postsynaptic side of the synapse Important Neurotransmitters include:Serotonin: Helps in the smooth transmission of messages in the brain and the body. Play important role in regulation of mood, appetite, memory and learning. A lack of serotonin may result in low self-esteem, depression, aggression.Dopamine: Plays a vital role in regulating pain and pleasure.\xa0Melatonin: Mainly related to wake and sleep cycles.Epinephrine: Plays a role in instant actions, such as those involving fear or danger.\xa0Acetylcholine: Enhances memory (it is the chemical responsible for many dreams)\xa0Endorphin (neuropeptide): The body’s natural pain killer.\xa0Cortisol (neuropeptide): A chemical released when we are under stress - at high levels, it can be dangerous because it interrupts transmission of messages from neuron to neuron. | |

Why carbon do not conduct electricity |
|
Answer» Carbon shares its electrons with other elements but it does not exchange electrons,i.e, it forms covalent compounds and not ionic compounds. Since there is no formation of ions, which are necessary for conducting electricity, carbon compounds do not conduct electricity. Bcoz carbon compounds do not form ionic bond they form covalent bonds, and ions are necessary for conductivity of electricity...... 1.) Bcz they have low melting and boling point...2.) And also poor conductor of electricity... Because carbon is a nonmetal.but graphite is an exception which conducts. |

Explain the different step involve in the secondry treatment of sewage |
| Answer» Secondary treatment/Biological treatment: Primary effluent is passed through large aeration tanks with constant mechanical agitation and air supply. Useful aerobic microbes grow rapidly and form flocs. The growing microbes consume organic matter and thereby, reduce the BOD of the effluent. After this, the effluent is passed into the settling tank. The bacterial flocs settle down and the sediment is now called activated sludge. A small part of the sludge is used as an inoculum in the aeration tank and the remaining part is passed into large tanks called anaerobic sludge digestors. In the digestors, heterotrophic microbes anaerobically digest bacteria and fungi in the sludge producing a mixture of gases such as methane, hydrogen sulphide and CO2\xa0which form biogas. | |

Answer» Like auxin which is help to growth in plants Harmones is a chemically substance which cordinate the activity of living things and growth also 1. Hormones of Thyroid: Thyroid gland basically releases two hormones Triiodothyronine (T3) and Thyroxine (T4), which helps in controlling the metabolism of our body. Further these hormones regulates weight, determines energy levels, internal body temperature, skin, hair etc.2. Insulin: This hormone is released by pancreas, a leaf like gland located in the abdominal cavity behind the stomach. It allows the body to use glucose or sugar from carbohydrates in the food for energy or to store glucose for future use. It helps in keeping blood sugar level from getting too high i.e. hyperglycemia or too low i.e. hypoglycemia.3. Estrogen: It is a female *** hormone released by the ovaries. It is responsible for the reproduction, menstruation and menopause. Excess of estrogen in the female body increases the risk of breast cancer, uterine cancer, depression, moodiness etc. If estrogen level is less in female body leads to acne, skin lesions, thinning skin, hair loss etc. |

Explain fertilization in flower |
| Answer» \tFertilisation is the process of fusion of male and female gametes.\tFor the fusion of male and female gametes pollen grains have to reach the surface of the stigma. This is called pollination.\tPollen grains received by the stigma, germinate and give rise to pollen tubes. Only one pollen tube finally reaches the embryosac.\tThis tube will have two male nuclei, which migrate to the tip of the pollen tube at the time of fertilization.\tUsually the pollen tube enters the ovule through micropyle and discharges the two male gametes into its embryosac.\tOne male nucleus (gamete) approaches the egg and fuses with it to form a diploid (2n) zygote. This is first fertilisation.\tThe other male nucleus (gamete) reaches the secondary nucleus (2n) and fuses with it to form endosperm nucleus which will be triploid. This is second fertilization in the embryosac.\tThus double fertilisation occurs in embryosac which is unique in flowering plants. | |

What are the harmful effect of fossil fuel |
|
Answer» The harmful effects can be by burning fossil fuels and using various techniques to reduce the escape of harmful gases and ashes into the surrounding The main reason why fossil fuels cause so much damage is due to the amount of carbon dioxide or CO2 emitted when fossil fuels are burned. This burning and release of CO2 is a huge contributor to the greenhouse effect and climate change. More CO2 in our atmosphere causes less sunlight to escape back into space, causing the planet to warm.When fossil fuels are burned, CO2 isn\'t the only gas released. Other harmful gases such as nitrogen and sulfur oxides. Burning fossil fuels causes air pollution and smog. |
