What is dark and light reaction please explain briefly |
| Answer» Photosynthesis is divided in two parts:1. Light-dependent reactions (light reactions)2. Light-independent reactions (dark reactions).Light reactions : As the name suggests, this reaction takes place in the presence of light. Light energy is absorbed by chlorophyll molecules and is utilized for splitting water molecules into hydrogen and oxygen. Additionally in this phase, assimilatory power in the form of ATP and NADPH2. Light reactions occur in the membranes of thylakoidsDark reactions : This reaction does not require direct light and occurs in the stroma of chloroplasts. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy, while NADPH provides the electrons required to fix the CO2(carbon dioxide) into carbohydrates. | |

plants are releasing oxygen in day time but not in night time so how we are leaving? |
|
Answer» I think the question is wrong because plants carry on the process of photosynthesis during day and release O2 and during night it releases O2 do u know 1 tree gives O² to 2 peoppes for example a plant release 400 oxygen in day time and we use 100 oxygen. so remaining oxygens are used in nigh time both plants & animals. This is due to transpiration. |

What is acidity ? How it cause ? |
|
Answer» Thanks Our stomach produces acid (mainly hydrochloric acid) to digest the food we eat. This is a regular and natural process. Whenever we eat, the cells present on the lining of the stomach pump acid to liquefy the food. If all is working properly (without gastric ulcer) the lining of stomach has an intact mucosal membrane which forms a barrier and protects us against the acid action.Problem occurs when these cells produce large amount of acid, more than your stomach needs. When this happens, you will suffer from stomach acidity; feel a burning sensation just above the stomach, or right below your breastbone. This is the most classic sign of acidity. Sometimes stomach acid is creeping back up to oesophagus, which is naturally an alkaline environment that also causes a burning sensation. |

Mitosis |
| Answer» Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis occurs only in eukaryotic cells and the process varies in different species. | |

Explain The Mechanism Of Preparing Food In Plants. |
| Answer» Sunlight is absorbed by stomata in leaves which is turn into chemical energy. This energy is used to break H2O into H2 and O2. O2 is realesed by stomata and CO2 is taken. H2 obtained by breakdown of H2O joins with NADP and form NADPH2. ATP is also form with NADPH2 in light reaction of photosynthesis. CO2 obtained by stomata is broken into a 6carbon molecule carbohydrate with energy of ATP and NADPH2 formed earlier. Carbohydrates are used as food. I hope you will understand this mechanism clearly. | |

How transpiration of blood taking place in our body |
| Answer» Most of the nutrients, waste products, useful gases, etc are carried by our blood. Thus, this blood needs to be pushed to each and every corner of the body, that too continuously. This job of pumping the blood around the body is done by our heart!The heart is a muscular organ which is as big as our fist.Now, since both oxygen and carbon dioxide have to be transported by the blood, the heart has different chambers to prevent the oxygen-rich blood from mixing with the blood containing carbon dioxide.1. The oxygen-rich blood from the lungs comes to the upper-left chamber of the heart, the left atrium. The left atrium relaxes when it is collecting this blood and then contracts, while the next chamber, the left ventricle, expands, so that the blood is transferred to it. When the muscular left ventricle contracts in its turn, the blood is pumped out to the body.2. De-oxygenated blood comes from the body to the upper – right chamber, the right atrium, as it expands. As the right atrium contracts, the corresponding lower chamber, the right ventricle, dilates. This transfers blood to the right ventricle, which in turn pumps it to the lungs for oxygenation. | |

How many type of gland found in our body ? Explain. |
|
Answer» Thanks ☺☺☺ Based on the way of secretion: Glands are two types based on secretion as1. Exocrine glands: They secrete into a location or region of the body through a duct and their secretions are called enzymes mostly while some are non enzymes.Types of exocrine glands and their secretions includeSalivary gland: In the buccal cavity secrete saliva. This saliva has many functions.Pancreas: Secretes enzyme amylase, trypsin and lipase. These enzymes digest carbohydrates, proteins and fats respectively.Sperm: Sperms produce Hyaluronidase an enzyme which helps it swim in the uterine tissue to reach ova. sweat glands: secrete sweat which acts to regulate body temperature and also excretion.Sebaceous gland: secrete sebum.Lachrymal glands: In eye secrete water to moisten the eye.Types of Glands2. Endocrine glands: Secrete into blood flowing through them, so as to let the secretion function at distant parts of the body from the gland. They are ductless glands. Their secretions are called as hormones.a) Pituitary Gland (of hypothalamus): This is a gland located below the hypothalamus in the brain.b) Thyroid gland: Produces thyroid hormones T3 & T4.c) Parathyroid gland: Produces parathormone.d) Adrenal gland: located on the two kidneys. It has outer cortex and inner medulla regions.e) Pancreas: Pancreatic gland has both exocrine and endocrine functions. It secretes multiple hormones which control body glucose metabolism. Its endocrine function release secretions like insulin, glucagon, somatostatin.f) Kidneys: produce Renin angiotensin (controls blood pressure).g) Pineal gland: Located inside the brain and called as body natural clock. One ca see jet-lag effects due to its secretions. Melatonin (sleep hormone). |

What is menstruation process |
| Answer» Menstruation is the process of the shedding of the uterine lining on a regular monthly basis. It begins at puberty and is the reproductive cycle of the female body. Every month, the uterus prepares itself to receive a fertilized egg. Therefore, the inner lining of the uterus becomes thick and is supplied with blood to nourish the embryo. If the egg is not fertilized, then the lining of the uterus breaks down and gets released in the form of blood through the ******. This lasts for about two to eight days. This cycle occurs every month and is known as the menstrual cycle. | |

Why the heartbeats of small baby is high as compared to an adult man? |
| Answer» Babies have a faster heart rate than adults because they are smaller. Typically, small mammals have much faster heart rates than larger mammals. For example, adult mice have an average resting heart rate of around 500 bmp, adult males around 70 bmp and adult elephants around 28 bmp.The reason is because the the smaller the animal (or person), the smaller the heart and the more work it has to do to maintain homeostasis in the body. This is because a smaller heart means smaller stoke volume per beat cycle | |
