  • Question: What is the effect of the urinary bladder in our body?

    Posted in: Biology | Date: 12/12/2016

    Answer:

     Although a person does not control kidney function, a person does control when the bladder empties. Bladder emptying is known as urination. The bladder stores urine until the person finds an appropriate time and place to urinate. A normal bladder acts like a reservoir and can hold 1.5 to 2 cups of urine. How often a person needs to urinate depends on how quickly the kidneys produce the urine that fills the bladder. The muscles of the bladder wall remain relaxed while the bladder fills with urine. As the bladder fills to capacity, signals sent to the brain tell a person to find a toilet soon. During urination, the bladder empties through the urethra, located at the bottom of the bladder.

  • Question: What is Down’s Syndrome?

    Posted in: Biology | Date: 12/12/2016

    Answer:

    Down syndrome is caused by a problem with a baby's chromosomes. Normally, a person has 46 chromosomes. But most people with Down syndrome have 47 chromosomes. In rare cases, other chromosome problems cause Down syndrome. Having extra or abnormal chromosomes changes the way thebrain and body develop.

  • Question: What is the effect of the blood vessels in our body?

    Posted in: Biology | Date: 12/12/2016

    Answer:

    There are three major types of blood vessels: the arteries, which carry the bloodaway from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.

  • Answer:

    The autonomic nervous system is divided into the sympathetic nervous system and parasympathetic nervous system. The sympathetic division emerges from the spinal cord in the thoracic and lumbar areas, terminating around L2-3. The parasympathetic division has craniosacral “outflow”, meaning that the neurons begin at thecranial nerves (specifically the oculomotor nerve, facial nerve, glossopharyngeal nerve and vagus nerve) andsacral (S2-S4) spinal cord.

  • Question: What is the function of hepatic caeca in a grasshopper?

    Posted in: Biology | Date: 12/12/2016

  • Question: main differences b/w charge and mass

    Posted in: Physics | Date: 13/12/2016

    Answer:

    1 Charge is of two types, mass is only of one kind

    2 There are two types of forces (attraction and repulsion) between charges, but there is only one kind (attraction) between masses.

    3 Charge is quantized, but quantization of mass is not established so far.

    4 Charge has SI unit coulomb, the SI unit of mass is kg.

    5 Charge is conserved, but mass alone is not conserved (Mass + Energy is conserved).

    6 Charge cannot exist without a mass, but mass can exist without a net charge.

  • Question: What is Haemophilia?

    Posted in: Biology | Date: 13/12/2016

    Answer:

    Haemophilia is a medical condition in which the ability of the blood to clot is severely reduced, causing the sufferer to bleed severely from even a slight injury. The condition is typically caused by a hereditary lack of a coagulation factor, most often factor VIII.

  • Answer:

    Xerophytes

    • Plant adapted to live in dry conditions. Common adaptations to reduce the rate of transpiration include:
    • Thick waxy cuticle: The cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature.
    • Sunken stomata: Stomata may be sunk in pits in the epidermis; moist air trapped here lengthens the diffusion pathway and reduces evaporation rate.
    • Hydrophytes

    • Plant adapted to live in extremely wet conditions. Common adaptations to increase the rate of gaseous exchange:
    • Leaf Shape: The submerged leaves are often highly dissected or divided to create a very large surface area for absorption and photosynthesis. It also minimises water resistance and hence potential damage to the leaves. In many cases, the submerged leaves are totally different to floating or emergent leaves on the same plant. The emergent leaves are usually much less divided, if not entire and have a more similar internal structure to those of land plants.
    • Lack of protective layer: The epidermal layer shows very little, if any, sign of cuticle formation, as water loss is not a problem. All the surface cells appear to be able to absorb water, nutrients and dissolved gases directly from the surrounding water. As a result, the xylem tubes is often greatly reduced, if not absent. *There are also no stomata on the underside of the leaves.

  • Question: What is Pleiotropy?

    Posted in: Biology | Date: 13/12/2016

  • Answer:

    Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

  • Answer:

    Racemose:

    1. The growth of the inflorescence is indefinite.

    2. The main axis does not terminate in a flower and continuous to grow and forms flowers laterally.

    3. The arrangement of flowers in the inflorescence is in acropetal succession with older flowers at the base and younger flower at the apex.

    Cymose:

    1. The growth of the inflorescence is definite.

    2. The main axis and its branches terminate in a flower.

    3. The arrangement of flowers in the inflorescence is in basipetal succession with older flowers at the top and younger flowers at the top and younger flowers at the base.

     

  • Question: What is Endosperm?

    Posted in: Biology | Date: 13/12/2016

    Answer:

    Endosperm is a tissue produced inside the seeds of most of the flowering plants following fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.

  • Answer:

    • Active water absorption occurs via root hair cells and passive water absorption occurs when transpiration rate is high.
    • Active absorption involves symplast movement of water and passive absorption involves apoplast movement of water.
    • Active absorption utilizes metabolic energy and passive absorption utilizes solar energy for transpiration.
    • Active absorption is independent of transpiration and passive depends upon transpiration.
    • Water is absorbed by osmotic and non osmotic process in active absorption. Water is absorbed as a result of tension created by transpiration pull in passive absorption.

  • Question: What is atavism?

    Posted in: Biology | Date: 13/12/2016

    Answer:

    In biology, an atavism is an evolutionary throwback, such as traits reappearing that had disappeared generations before.Atavisms can occur in several ways. One way is when genes for previously existing phenotypical features are preserved in DNA, and these become expressed through a mutation that either knocks out the overriding genes for the new traits or makes the old traits override the new one.

  • Question: What is a vestigial organ?

    Posted in: Biology | Date: 13/12/2016

    Answer:

     A rudimentary structure in humans corresponding to a functional structure or organ in ancestral animals.In humans the vermiform appendix is a vestigial structure; it has lost much of its ancestral function.

  • Answer:

    Double fertilization was discovered more than a century ago by Sergei Nawaschin in Kiev Russian Empire, and Léon Guignard in France.

  • Question: What are the different types of natural selection?

    Posted in: Biology | Date: 15/12/2016

    Answer:

     

    The three types of natural selection are directional selection, disruptive selection and stabilizing selection. Natural selection is when organisms adapt to the environment and pass down these adaptations to their offspring when they breed. Those that are not able to adapt die before breeding, putting an end to unfavorable traits.
