Answer
Answer
  • Question: Define transpiration pull

    Posted in: Biology | Date: 16/06/2017

    Answer:

    It is a physical process where a column of water molecules is pulled up gradually, in the xylem vessels, due to loss of water from stomatal openings in the form of vapours. It helps transport water in plant body and is more in day than at night as well as on windy days.

  • Answer:

    Once their work is done, the enzymes are broken down and the constituents reabsorbed in the body. Fresh new enzymes are reformed when food again enters after sometime. This happens because all enzymes are proteins and our body will eventually digest even this form of protein.

  • Answer:

    In stress the sympathetic nervous system is activated and one of its nerves( from thoracic region of vertebrae) stimulates the Adrenal glands in its medulla region. This causes release of Adrenaline and this hormone affects heart and increases its beats. It mainly constricts blood vessel which makes the heart beat more to compensate for slow flow of blood. Yet another hormone called cortisol or the stress hormone is released by Adrenals from its cortex part. This also forms part of the "flight or fright"response and can affect the heart rate.

  • Answer:

    Both are equally competitive. In TOEFL, especially the computer based, time is of utmost value. You hardly can digress from your concentration as you stand to loose information. Once you click an answer, its done. In speaking also, once the mic is on, you can't stop midway to think. In IELTS, even though conversation is happening face to face, which is psychologically comforting, the level of questions and grading them is quite complex. If your English is 7 out of 10, according to you, you may need atleast 2 months proper coaching to obtain a good band score.

  • Answer:

    Water, root hair, critical cell, xylem, vein

  • Question: Why is insulin given in type 2 diabetes?

    Posted in: Biology | Date: 16/06/2017

    Answer:

    In type 2 diabetes, body( specifically, beta cells of pancreas) either produces too less insulin(as they are burnt out over the years) or body cannot utilise it normally. Hence insulin injections are taken. Also, as Insulin is a protein, it cannot be eaten because your body will digest it like any other protein. Thus, the intramuscular dose.

  • Question: Do all organs of our body secrete hormones?

    Posted in: Biology | Date: 16/06/2017

    Answer:

    No. Only Endocrine glands can produce hormones. These are ductless glands. Few examples are: thyroid, pituitary, Adrenals, thymus, gonads etc. Pancreas is a mixed gland(se creating both hormones and enzymes)

  • Answer:

    Partly this is determined by sex hormone. Females tend to accumulate fat more in pelvic region while men tend to have pot belly fat. Women tend to have larger fat cells and as such more fat in them then men. Due to child birth, it is beneficial for them. Thus, receptors for this hormone are distributed differently in men and women and this causes fat to deposit in the mentioned pattern. Research is on in this area though. Also, cortisol, the stress hormone, plays a role in fat metabolism. It increase fat deposits in those people who remain in prolonged stress.

  • Answer:

    Till date, no major function has been attributed to these cells although it is seen that they increase in number with age. One research study proposes that they may be producing hormone PTH under diseased condition known as secondary parathyroid hyperplasia. But literature on this cell is limited still.

  • Question: What really causes cancer?

    Posted in: Biology | Date: 16/06/2017

    Answer:

    When a cell cannot stop dividing, the organ mass grows without reason or restriction. We can say that the cell cycle is now disturbed. This uncontrollable growth is tumor and when such damaged cells break away from organ and flow to other organs we can say the original organ is now cancerous. Cause for cell cycle disturbances are many: viral infections, switching on of oncogenes already present in all of us, some radiation that switched on oncogenes or any other reason. Our cells have few genes called tumor suppressing genes. They work perfectly and do not allow tumor to build. But, if they mutate(change their genetic formula), their beneficial activity is lost and tumor begins to develop. This can form cancer when it's cells break away and flow in blood, a condition called as metastasis.

  • Answer:

    1. It allows passive diffusion of small proteins (5000Daltons or less) inside the mitochondrial. 2. It contains few enzymes(monoamine oxidase, fatty acid Co-A ligases etc.) These perform various functions like elongation of fatty acids, tryptophan degradation, oxidation of Adrenaline etc. 3. It creates a channel for lipid movement between ER and interior of mitochondrial. 4. It transfers larger proteins by using its lager translocases which are multi-unit proteins aka Porins. ATP is used in this transport (Active transport).

  • Question: Why sea water fish can't survive in Fresh water?

    Posted in: Biology | Date: 16/06/2017

    Answer:

    One must understand osmosis for this. Salt water attracts water. Fresh water tends to supply-in the water. If sea water fish,who is already having more salt in its body cells, in put in freshwater, its gills cells will keep soaking in water by endosmosis, till it dies. Opposite will happen to a freshwater fish. If put in salty water, with each breath, when salty water passes out from its gills, it will suck out water from fish cells till it dies of dehydration.

  • Question: What are the consequences of inbreeding?

    Posted in: Biology | Date: 17/06/2017

    Answer:

    1. Loss of genetic vigor 2. Inbreeding depression (producing unfertile weak offspring) 3. Higher chances of genetic disorders( usually recessive gene disorders) 4. No improvement in species. No new feature development. 5. Smaller size, Lower fertility, few offspring slower growth.

  • Answer:

    Plant cell contains a large food vacuole filled with cell sap. This occupies 80 percent space or more. This pushes the nucleus at the periphery or towards a corner.

  • Question: How do we differentiate organ and tissue?

    Posted in: Biology | Date: 17/06/2017

    Answer:

    1. Based on functionality: Tissue cannot function on its own. Organ can function. 2. Cell variety: tissue has one type of cell only. An organ has many types of cells in it.

  • Answer:

    When in stress our autonomic nervous system (ANS),more specifically its sympathetic nervous system branch comes in action. It transfers the blood flow from gut to muscles, a step towards emergency preparation. This reduces activity of gastric muscles, they contract as do the surrounding blood vessels. This sensation is felt by us as butterflies in the stomach. Adrenaline is also released as a part of sympathetic activity which is commonly referred to as flight or fright response. ( The opposite is parasympathetic response,also known as rest and digest response)

  • Answer:

    Vitamin B-12, Cobalamin or Cyanocobalamin, is absorbed in GI, in duodenum with help of intrinsic factors. In blood, it combines with Transcobalamin and transported to liver where it can be stored for many years.

  • Question: Defination of variations in genetics

    Posted in: Biology | Date: 21/06/2017

    Answer:

    Variations can be defined as mutations(changes in DNA) in alleles of a chromosome which causes structural, physiological or behavioral changes in the offspring carrying that variation. Over time variation spreads and the complete population may start showing a new feature.

  • Answer:

    Colorblind woman= X""X"" {"" indicates affected chromosome} Normal man= X Y If a son is born, he will be= X""Y (Colorblind, always getting the affected chromosome from his mom) If a daughter is born, she will be X""X (carrier, but not colorblind as she gets one normal X from her dad) Hence, all sons will be born colorblind(100% cases) and all daughters will be just carriers (100%cases, as she needs both Xchromosomes to be affected to actually suffer from the disease)

  • Answer:

    This is because for a son, even if one affected chromosome is present, it will show the disease but for a daughter both X chromosomes must be affected only then she will show the disease. Therefore, males have higher chance of suffering from it.

  • Question: Why do we feel headache after ice cold drink?

    Posted in: Biology | Date: 21/06/2017

    Answer:

    This phenomenon is commonly called Brain Freeze. It happens on consuming cold drinks or ice cream quickly on a hot day. The upper part of mouth, the upper palate, suddenly gets cold and its capillaries shrink. But you are breathing hot air from nose, which warms those capillaries and they expand. These sudden changes near sinus area stimulates your sensitive nerves which starts the headaches.

  • Answer:

    If you run your fingers, you may feel sensations, lowest till 10-11 microns. On your palm you may feel sensations between 10-40 microns.

  • Answer:

    There are 3 forms of DNA, each has different no. of base pairs (bp) per turn. The B-form which is most common has 10bp, A-form has 11 base pairs and Z-form has 12 bp. (A and B form are Right hand twisted helix while Z-form is the left hand twisted helix)

  • Question: Bionomial system of nomenclature was given by?

    Answer:

    Carolus Von Linnaeus

  • Question: How many chromosomes does a human cell have?

    Posted in: Biology | Date: 26/06/2017

    Answer:

    Sex cells/ Germ cells, sperm and ova, contain 23 chromosome. This half value is called haploid number. Rest of the body cells, also called somatic cells, have double that, so 46 chromosome. This value is called Diploid number.

  • Question: 'Nucleus hereditary centre of the cell'Discuss

    Posted in: Biology | Date: 01/07/2018

    Answer:

    Nucleus contains DNA, therefore it acts as hereditary center but only in Eukaryotes. In Prokaryotes, there is no Nucleus. Yet they can transfer genes. So basically it's the DNA matter that's hereditary in nature. Also, a little DNA is present in mitochondria and plastids(plants only). Even these transfer important genes at the time of cell division. Such inheritance (from mitochondria and plastids) is called extra chromosomal inheritance i.e. inheritance from DNA that isn't connected to chromosome in nucleus, but DNA which occurs in organelles.
