Mechanism of pacemaker |
|
Answer» The cells that create these rhythmic impulses, SETTING the PACE for blood pumping, are called pacemaker cells, and they DIRECTLY control the heart rate. ... In most humans, the concentration of pacemaker cells in the sinoatrial (SA) node is the natural pacemaker, and the resultant rhythm is a sinus rhythm. This is a common misunderstand- ing. A pacemaker does not ACTUALLY BEAT for the heart, but delivers en- ergy to stimulate the heart muscle to beat. Once someone stops breathing, his body can no longer get oxygen and the heart muscle will die and stop beating, even with a pacemaker. thnx hope dis hlps uh |

Based on the position of the centromere, chromosomes are classified into four types.Explain. |
|
Answer» STRUCTURE and Function of the Centromere CENTROMERES consist of a complex combination of proteins and DNA. They are essential to the division of CELLS and ensure the accurate segregation of chromosomes. Studies have demonstrated that chromosomes without centromeres segregate RANDOMLY and are eventually lost from cells. In contrast, chromosomes that have multiple centromeres can be subject to fragmentation. Metacentric Chromosomes Metacentric chromosomes have the centromere in the center, such that both sections are of equal length. Human chromosome 1 and 3 are metacentric. Submetacentric Chromosomes Submetacentric chromosomes have the centromere slightly offset from the center leading to a slight asymmetry in the length of the TWO sections. Human chromosomes 4 through 12 are submetacentric. Acrocentric Chromosomes Acrocentric chromosomes have a centromere which is severely offset from the center leading to one very long and one very short section. Human chromosomes 13,15, 21, and 22 are acrocentric. Telocentric Chromosomes Telocentric chromosomes have the centromere at the very end of the chromosome. Humans do not possess telocentric chromosomes but they are found in other species such as mice. |

How help pesticides and insectisides in growth of cultivation? |
|
Answer» The best way to protect your crops is to KEEP pests away from your field. ... Mulch your crop to help its growth. Mulching also helps soil keep its moisture, and helps stop some weeds, insects, and diseases from spreading. The primary benefits are the consequences of the pesticides' effects – the direct gains expected from their use. For example the effect of killing caterpillars feeding on the crop brings the primary benefit of higher yields and better quality of cabbage. The three main effects result in 26 primary benefits ranging from protection of recreational turf to saved HUMAN lives. The secondary benefits are the less immediate or less obvious benefits that result from the primary benefits. They may be subtle, less intuitively obvious, or of longer term. It follows that for secondary benefits it is therefore more difficult to establish cause and effect, but nevertheless they can be powerful JUSTIFICATIONS for pesticide use. For example the higher cabbage yield might BRING additional revenue that could be put towards children's education or medical care, leading to a HEALTHIER, better educated population. There are various secondary benefits identified, ranging from fitter people to conserved biodiversity.thnx hope dis hlps uh |

How does many antibodies are produced from fewer genes? |
| Answer» ANTIBODIES are produced from three pools of gene segments and EXONS. ...

What is connective tissue and it's type |
Answer» CONNECTIVE TISSUEIn the body of complex animals connective tissues are widely ranged and they have a specialized functioning of linking and supporting the various parts of our body. That's why they are called connective tissue. It has three main components :- cell, fibres and ground tissue. Fibres helps in providing support, flexibility and elasticity to the tissue and ground tissues are the fluids that fills spaces between the fluid and the cell. Connective tissues are of three types:-
Loose connective tissueLoose connective tissue are those tissues which are loosely arranged in a semi-fluid ground tissue and are divided into three types i.e. Areolar and Adipose.
Dense connective tissueDense connective tissues are those tissues which are compactly packed and consisis of predominately fibres. These are of TWO types :- Tendons and Ligaments.
Special connective tissuesSpecial connective tissue are those type of connective tissue which have unique cell and extracellular matrix which performs specialized functions. These are of three types :- Cartilage, Bone and Blood.

Discuss briefly the following:(a) Radioactive wastes(b) Defunct ships and e-wastes(c) Municipal solid wastes |
|
Answer» HEY mate Here is ur answer (a) Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications ofnuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by GOVERNMENT agencies in order to protect human health and the environment. (b) Defunct ships and e-wastes: - Defunctships are dead ships that are no longer in use. Such ships are brokendown for scrap metal in countries such as India and Pakistan. Theseships are a source of various toxicants such as asbestos, lead,mercury etc. Thus, they contribute to solid wastes that are hazardousto health. E-wastes or electronic wastes generally includeelectronic goods such as computers etc. Such wastes are rich inmetals such as copper, iron, silicon, gold etc. These metals arehighly toxic and pose serious health hazards. People of developingcountries are involved in the recycling process of these metals andtherefore, get exposed to toxic SUBSTANCES present in these wastes. (c) MUNICIPAL solid wastes: - Municipal solidwastes are generated from schools, offices, homes, and stores. It isgenerally rich in glass, metal, paper waste, food, RUBBER, leather,and textiles. The open dumps of municipal wastes serve as a breedingground for flies, mosquitoes, and other disease-causing microbes.Hence, it is necessary to dispose municipal solid waste properly toprevent the spreading of diseases. Sanitary landfills andincineration are the methods for the safe disposal of solid wastes. |
