Re: Vitamin Supplements

It is always better to get zinc from food sources.As a supplement, you should take only correct dose as advised by your doctor. You should also space it time wise from other medicines if you are taking, as zinc can int...

Re: Growing Taller

Hey, Just a minute,while the teens keep trying everything on earth to increase their height and invariably end up to their natural limit, is it true to imagine all is right with tall guys? How do the tall guys think of themselves? Won't they find little odd in the company of people with average heig...

Re: Human chromosomes

Hi,
There are 23 pairs, because when gametes fused during fertilization, each partcipating gamete had only 23 nonpaired (single) chromosomes and got paired after the gametes fused.
In other words each parent contributed one chromosome in each pair.

Re: Smoking during pregnancy

Hi, By a little off-subject thinking, I wonder why people smoke at all, let alone smoking during pregancy period, knowing pretty well that there are hundred and one bad effects to smoking. If the argument for continuing smoking is one of addiction, I have a different perspective, I have seen hard he...

Re: Anal Bleeding. Pleas help.

Hi,
Some of the common causes of rectal bleeding are Piles,
Amoebic Dysentery, or even Constipation, which are easily diagnosable by associated symptoms. But for a boy of your age, you should lose no time and get it checked up by a qualified Doctor.

Re: Growing Taller

Hi, Here is a good reference for those height-savy teens: m My personal advice is to avoid any chemical routes to height increase unless it is absolutely essential and should it be done at all, it should be strictly by consultation with a qualified doctor. For instance a height of 5'7'' is a good av...

Re: brain power

Hi JackBean, Yes, ketone bodies can be used by brain, but as I understand, it is a very slow process and is used only when blood glucose is in short supply for longer periods as in fasting. For faster energy requirements, the body first uses ATP and glucose derived from glycogen stored in the muscle...

Re: brain power

Hi mith, Yes, in a way Yes and in away No. The main point I want to make is that the brain depends only on blood glucose for its energy requirements, where as other body cells can also burn fat and get energy. Since you get more energy by burning fat compared to glucose, and during intense mental ac...

Re: brain power

Hi Mith,
True, but then I would think that the amount of fat burnt during exercise is much more than that during mental exercise.

Re: brain power

Hi, I Think the main difference is that when we do intense brain activity, we use up blood glucose where as in long term physical activity, we burn up also fatty acids stored in the adipose cells. So, we can reduce weight by reducing body fat by physical exercise, but not by mental exercise. Also, b...

Re: How does it know?

Hi, I agree with biohazard that a virus may be considered as a biological nano machine, though may not fit into the standard definition of a living being. The selectivity of a virus to a specific host cell is determined by the matching cell characteristics. In this context,the infection of bacterial...
