Why red tides caus diseases and why they are harm full |
| Answer» A\xa0red tide is caused\xa0by an increase in the population of toxic algae. ... A\xa0red tide occurs\xa0when the population of certain kinds of algae known as dinoflagellates explodes, creating what\'s called an "algal bloom." Scientists sometimes refer to\xa0red tides\xa0as harmful algal blooms or HABs.\xa0Red tide\xa0is a phenomenon caused by algal blooms (Wikipedia definition) during\xa0which\xa0algae become so numerous\xa0that they\xa0discolor coastal waters (hence\xa0the\xa0name "red tide").\xa0The\xa0algal bloom may also deplete oxygen in\xa0the\xa0waters and/or release toxins\xa0that\xa0may\xa0cause illness\xa0in humans and other animals. | |

Is lymph and filtrate formed by kidney after ultra filtration are same in their concentration |
| Answer» The Three Steps of\xa0Urine\xa0Formation. The kidneys filter unwanted substances from the blood and produce\xa0urine\xa0to excrete them. There are three main steps of\xa0urine\xa0formation: glomerular\xa0filtration, reabsorption, and secretion.\xa0Filtrate\xa0is produced by the glomerulus when the hydrostatic pressure produced by the heart pushes water and solutes through the\xa0filtration\xa0membrane. Glomerular\xa0filtration\xa0is a passive process as cellular energy is not used at the\xa0filtration\xa0membrane to produce\xa0filtrate.\xa0Filtration takes place in the glomerulus , which is the vascular beginning of the\xa0nephron\xa0. Approximately one-fourth of the blood flow from cardiac output circulates through the kidney, the greatest rate of blood flow for any organ . | |
| 61. |
In which part of nephron filtration takes place? |
|
Answer» Renal corpuscles or maphigian tubule The part of the Nephron in which the filtration occurs is called the Glomerulus. A nephron is composed of the "Bowman\'s capsule" and the "Loop of Henle". The dynamic "physical forces" determine the single "nephron glomerular filtration". Here the Malpighian capsule or Glomerulus are placed in the Bowman\'s capsule where the filtration occurs.Malpighian capsule consists of connecting capillaries and forms the major portion of the glomerulus. |

State the location and function of different types of meristem |
| Answer» Meristem : A meristem or meristematic tissues is a group of cells that are in a continuous state of division and thus continuously produce new cells. Location and function of meristems : On the basis of location and function, the meristems are of the following types:(1) Apical meristems : These are present at the apices of stems, roots and branches. The activity of the apices of stems, adds to the length of the plant or its part.(2) Intercalary meristems : These meristems are intercalated in between the permanent tissues. They may be present either at the base of the internode as in the stem of various grasses and wheat; or at the base of the leaf as in pinus; or at the base of a node as in mint. The activities of these meristems also add to the length of the plant or its organs.(3) Lateral meristems : These meristems are present along the side of the stem. These include cambium and cork cambium. The activity of lateral meristems adds to the thickness of the plant. | |

Why is food transported in the form of sucrose in phloem? |
| Answer» Transport of food material from leaves to other parts of the plant is called\xa0translocation. This food may be stored in fruits, stem or roots. The movement of food can be upward as well as downward depending upon the needs of the plants.The movement of food in the phloem takes place by utilizing energy. The areas where the nutrients are stored is known as sink (e.g. root) and where they originate as source ( leaf). The movement of food is always from the source to the sink. At source i.e leaves, food is prepared in the form of glucose. Glucose is converted into sucrose. Sucrose enters into the phloem at the expense of energy from ATP. A pressure gradient is set up in the phloem with high pressure at source and low pressure at sink. So the phloem sap with food will move from source to the sink. The phloem transports food according to the need of the plant. | |

Which immune response is responsible for rejection of kidney graft and why? |
| Answer» Graft\xa0rejection\xa0occurs when the recipient\'s\xa0immune system\xa0attacks the donated graft and begins destroying the\xa0transplanted\xa0tissue or\xa0organ. The\xa0immune response\xa0is usually triggered by the presence of the donor\'s own unique set of HLA proteins, which the recipient\'s\xa0immune system\xa0will identify as foreign. Immune response is responsible for rejection of kidney graft\xa0because the person\'s\xa0immune system\xa0detects that the antigens on the cells of the\xa0organ are\xa0different or not "matched." Mismatched\xa0organs, or\xa0organs\xa0that\xa0are\xa0not matched closely enough, can\xa0trigger\xa0a blood transfusion\xa0reaction\xa0or\xa0transplant\xa0rejection. | |

Triple fertilization |
| Answer» The\xa0fusion\xa0involving two polar nuclei and a sperm nucleus that occurs in double\xa0fertilization\xa0in a seed plant and results in the formation of the endosperm.\xa0The flower may be unisexual that is, it contains either stamens or carpels or bisexual which contains both stamens and carpels. Stamen produces pollen grains that are yellowish in colour. The ovary contains ovules and each ovule has an egg cell. When a pollen grain falls on the stigma of the carpel, it bursts open and grows into a pollen tube downwards through the style towards the female gamete in the ovary. A male gamete moves down the pollen tube and enters the ovule in the ovary. The tip of the pollen tube bursts open and male gamete comes out of the pollen tube which combines with the nucleus of the female gamete present in the ovule to form a fertilised egg called zygote. This is called double fertilization.\xa0Triple fusion\xa0is a\xa0fusion\xa0that involves a sperm nucleus and two polar nuclei which occurs in the double\xa0fertilization\xa0in a seed-bearing\xa0plant\xa0that results in the endosperm formation.\xa0 | |

Describe ultrafiltration |
| Answer» Ultrafiltration is a process in the kidney by which urea, salt, water and glucose etc. is extracted from the blood. When blood passes through the top of the nephron, it enters a structure called the glomerulus which is a network of tiny capillaries. This causes the pressure to increase and fluid is forced through the "sieve-like" walls of the vessels into the Bowman\'s capsule. This fluid is called the filtrate. Blood cells and larger proteins do not pass through the capillaries as they are too large and so are not found in the filtrate. A large proportion what enters the filtrate is valuable to the body and so needs to be reabsorbed into the blood. This is a process called selective reabsorption. | |

Difference between alveoli air and inspired air |
| Answer» Inspired\xa0gas is the gas we take in during breathing which mostly contains oxygen in adequate amount whereas\xa0expired\xa0gas is the gas we breathe out which is mostly carbon dioxide.\xa0Inspired\xa0gas is mainly used for the oxidation of food for energy whereas\xa0expired\xa0gas is the bi product of oxidation and is toxic in nature.\xa0The\xa0air\xa0that we\xa0inspire\xa0is a mixture of gases. The most important of these are nitrogen, oxygen, carbon dioxide and water vapour.\xa0Dead space gas is not identical to inspired gas. It is warmed and humidified. Mixed\xa0expired air\xa0is somewhere in composition between\xa0alveolar\xa0gas and room\xa0air, so its\xa0oxygen\xa0level is higher\xa0than alveolar\xa0gas and its CO2 lower. | |
