functions of glucagon n insulin plz..

Glucagon is secreted by the pancreas (islet cells) and is a hormone in which it is targeted to the liver to LOWER the sugar level in the blood..this is when there is a low amount of glucose in the body
(a.k.a storage sorter of the body)..while Insulin again secreted by the pancreas, is again targeted to the liver to stimulate it to convert the stored glucose (glycogen) into glucose to INCREASE the level of glucose in the blood

AAnsarii , insulin lowers blood sugar level and glucagon increases it! not the opposite.

when there's low glucose in d blood, glucagon is secreted, n when there's high glucose, insulin is?

Yes

If you are unsure, mention it so that others are not confused!

well, i was unsure at the last minute...and sometimes my 'unsure-ing-ness' gets me faulty ..

Chemistry, O/N 2009 Paper 1, Q13 ???

NaOH forms at the negative electrode it turns blue/purple & at anode forms chlorine so it becomes colourless (bleached)

 

[L.V.D]

In Biology what is the difference or what are they actually
herbicides pesticides insecticides .......etc?

ASKED BY A MEMBER BUT I DONT KNOW THE ANSWER TOO !! ANYONE HERE KNOWS THE ANSWER ????

Q: In some countries, ethanol, rather than petrol, is used as a fuel for cars. Which gas is not present in the exhaust from cars that burn ethanol?

A Carbon dioxide
B Nitrogen
C Oxides of nitrogen
D Sulphur dioxide​

Thanks alot, however, I checked online, and they said that chlorine cause is acidic and causes universal indicator to turn red :S

but there's a test for chlorine with damp litmus paper and it gets bleeched wen chlorine is passed through it

Chemistry MCQ doubt:​

​

Q: In some countries, ethanol, rather than petrol, is used as a fuel for cars. Which gas is not present in the exhaust from cars that burn ethanol?​

​

A Carbon dioxide​

B Nitrogen​

C Oxides of nitrogen​

D Sulphur dioxide​

D it is sulfur dioxide because when u burn ethanol u release oxygen and water, however oxides of nitrogen and nitrogen occur and the fuel used has no effect on them, sulfur dioxide is the answer because it can only be made by the combustion of a sulfur containing fuel

ur right, i did that question before

 

[ameeron]

True, but I guess that litmus paper is different from universal indicator
