Why does LOWERING the ionic STRENGTH of a solution of double-stranded DNA permit the DNA to denature more readily (for example, to denature at alower temperature than at a higherionic strength)? Lower ionic strengthreduces the screening of the negative charges on the PHOSPHATE groups by POSITIVE ions in the medium.

You do not need to perform any heat balance. If the inlet temperatures of the hot fluid and cold fluid are held steady, then steady state is indicated by the constancy of one of the outlet temperatures. If you are recording the temperatures and can see the temperature history on the computer screen, it is a simple matter to judge STEADINESS. The effect of noise on temperature of the fluid is so small that your thermometer cannot detect it. If you have serious disturbances, you can never get steady conditions. Eliminate those disturbances.

"Steady state" is a relative TERM. Unsteadiness can even be caused by, say voltage fluctuations, which MAY cause a change in flow rate. You might be able to set an arbitrary band (say 1% of the MEASURED value about the mean), so that if the fluctuations are less than that, you may take it as 'nominally steady'. That should do for your purpose.

Darwin proposed the theory of evolution by means of natural selection. According to this theory  natural selection is the mechanism by which new species ARISE from pre existing ones. Natural selection states that there is "struggle for existence" within a population and variation exists within all population. The continuous competition between individuals for ENVIRONMENTAL resources creates a 'struggle for existence' and this struggle makes sure that certain organisms would fail to survive or reproduce. This would ELIMINATE less suited organisms and BETTER adapted organisms would survive and PASS on their traits to next generation leading to evolution.

What about TRANSPORT in plants, how does a Redwood, one of the tallest trees in the world, move water from the soil to the needles on its tallest branches over 300 ft in the air? (That’s over 30 stories high!) Or how does a carrot transport the sugars made in its green, leafy tops below the surface of the soil to grow a sweet, orange taproot? Well, certain TYPES of plants (vascular plants) have a system for transporting water, minerals, and NUTRIENTS (food!) THROUGHOUT their bodies; it’s called the vascular system. Think of it as the plant’s plumbing, which is made up of cells that are stacked on top of one another to form long tubes from the tip of the ROOT to the top of the plant. To learn more about it, let’s study the stem.

The functioning of the kidney is efficiently monitored and regulated by the hormonal feedback mechanism involving the hypothalamus JGA and a certain extent the heart
osmoreceptors in the BODY are activated by the changes in the blood VOLUME body fluid volume and the ionic concentration
an excess loss of the fluid from the body can activate these receptors which stimulate the hypothalamus to release the antidiuretic hormone ( adh) or vasopressin from the neutrophylesis ADH facilitates water reabsorption from later parts of the tubule thereby preventing the a DIURESIS
an increase in body fluid volume can switch off the osmoreceptors and suppress the A D H released to complete the feedback A D H can also affect the kidney function by is constructive effect on blood vessels
discos an increase in the blood pressure and increase in the blood pressure can increase the Glomerular blood flow and thereby the GFR
a g a place a complex regulatory role a fall in global Arora blood Donor blood pressure can active the JG cells to released renin which converts angiotensinogen in blood to angiotensin 1 and further to angiotensin II being powerful vasoconstrictor increase the glomerular blood pressure and thereby GF or angiotensin II also activates the adrenal cortex to release aldosterone . aldosterone CAUSE reabsorption of Na+ and water from the distal parts of the tubule
this also leads to the increase in the blood pressure and GF are these Complex mechanism is generally known as known as the renin angiotensin mechanism

an increase in blood flow to the Atria of the blood can cause the release of atrial natriuretic factor (AFN ) can cause vascodilation and thereby the blood pressure ,AFN mechanism therefore acts as a check on the renin - angiotensin mechanism

Replicative senescence of T cells is correlated with erosion of telomere ends. Telomerase plays a key role in maintaining telomere length. Therefore, it is thought that telomerase regulates the life span of T cells. To test this hypothesis, we have over-expressed human telomerase reverse transcriptase in human CD8+ T cells. Ectopic expression of human telomerase reverse transcriptase led to immortalization of these T cells, without altering the phenotype and without loss of specificity or functionality. As the T cells remained dependent on cytokines and Ag stimulation for their in vitro expansion, we conclude that immortalization was achieved without malignant transformation.

The ends of linear eukaryotic chromosomes, which are called telomeres, consist of DNA-protein complexes ending in a large duplex loop (1). They serve to maintain CHROMOSOMAL integrity and prevent end-to-end fusion of the chromosomes. Telomere length is not constant over time. The telomeric ends have a length of 5–15 kb in humans and shorten by 50–100 bp per cell division in normal somatic cells (2, 3). When telomeric ends get too short, cells will enter a state of replicative senescence followed by crisis and cell death. Thus, telomere shortening may prevent unlimited proliferation of human somatic tissues. Telomere shortening is counteracted by the RIBONUCLEOPROTEIN enzyme complex called telomerase, which has two key components, the telomerase reverse transcriptase (TERT)4 and telomerase RNA, which is used as a template to elongate telomeric ends (for reviews see Refs. 4, 5, 6). The crucial role of human (h)TERT in maintaining telomeric length and subsequently of the replicative life span of cells has been demonstrated recently. It has been documented that ectopic expression of hTERT, in cell types without endogenous expression of hTERT, led to elongation of the telomeres and to an increased life span of foreskin fibroblasts, retinal pigment epithelial cells, and endothelial cells (7, 8, 9), indicating that hTERT by itself regulates the life span of these cell types. In other cases, however, ectopic expression of hTERT was not sufficient and had to be accompanied by an inactivated Rb/p16INKa pathway to give similar effects in human mammary epithelial cells and foreskin keratinocytes (10)

A correlation between telomere shortening and life span has ALSO been found in cells of the immune system. It was reported that the average telomeric length and the replicative potential are higher in naive T cells as compared with memory T cells from the same donor, in both CD4+ cells (11, 12) and CD8+ cells (13, 14). These findings are consistent with two ex vivo studies with peripheral blood leukocytes, indicating a correlation between the loss of telomere repeat fragments and the age of the donor (15, 16). Ongoing shortening of telomeres and subsequent induction of replicative senescence in cells of the immune system occur despite the presence of endogenous hTERT in T and B cells

The PROCESS of CREATION of genetically identical person from either a living or dead person is known as human CLONING. It includes the production of clone tissues, also donated from the individual to be cloned. This term refers to artificial human cloning only. The birth of twins is called natural human cloning. Even though the birth of twins is the result of natural human cloning they are separate people with separate experience. The presence of identical DNA makes no difference in their being different personalities. The scientific community all over the world is still investigating the question how similar the original and its clone would be and this may depend up on how much of personality traits are determined by genes.

Scientists have managed to clone animals like Dolly, the sheep. They have obviously tried the same method on humans, and have reached considerable success. However, many countries and governments have banned human cloning fearing the ill-effects of human clones. The human race is not yet prepared to come face-to-face with clones moving about with normal people. There is a huge debate on the pros and cons of human cloning. This BiologyWise article on human cloning will cover the advantages of cloning humans.

Techniques of Human Cloning and Claim of Success

The most common technique used in human cloning is 'somatic cell nuclear transfer'. Under this technique, the nucleus of an egg cell taken from a donor is removed. Then, the original cell gets fused with another cell of same genetic material to be cloned. Another technique used, is PARTHENOGENESIS. This technique involves inducement of unfertilized egg to divide and grow as if it were fertilized. As recently as on May 2005, a team of scientists led by Mr Hwang Woo-Suk attached to Seoul National University, claimed to have CREATED 11 lines of human stem cells using a different technique
