Q) explain difference between an allele and a gene ?

 

[SALT]

platelets gather in the cut region

​

secrete thrombin​

which converts soluble fibrogen to insoluble fibrin​

which forms a mesh over the wound​

which traps RBCs and more platelets​

which forms a scab over the wound​

​

uve got tht wrong.....platelets secrete thrombokinase which converts prothrombin to thrombin
den thrombin converts fibrinogen to fibrin which traps rbcs to form a scab...

lol jk
asexually

They do reproduce sexually! dont they..?
They're part of flowers or something?!

Genes come in brands like Levis and GaP and whatnot
And alleles sound funny..

are you trying to be funny or you seriously dont know what they are ?

no they dont.

 

[Tharindu]

I need physics notes...pls help

 

[Umar Ilyas]

no they dont.

Do elaborate further please?

 

[Fallen316]

Do elaborate further please?

can't
i don't know any further about it

 

[Muhammad Zain Qasmi]

th

google tells me that it is either measured in frequency or Decibels...

Thats the thing even google doesnt have an answer to. I AM JUST SAYING HOW COME YOU INCREASE/DECREASE VOLUME IN A TV, SO IT MUST BE RELATED TO SOUND IN SOMEWAY ??

 

[Umar Ilyas]

can't
i don't know any further about it

I read that apples trees are insect pollinated

Only part that is difficult in biology is Seed Germination!
Anyone who is able enough please reply on how are seed germinated and speacially what are Pumule and Radcle!

 

[Dukeofwin]

it
s D that is 1.oo becuase recessive characterstic is always homozygous if it would be hetrozygous the dominant one will show its effect so it is always homozygous!
Furthermore, 1.oo probability means a 100% chance so D is the correct choice!!..

Thanks alot, but Ashiqbal did the explanation earlier! However your reply is appreciated

in english, "volume" has 4 meanings none of which are related to each other
1 Quantity
2 Loudness of sound
3 Space occupied by an object
4 A book

dis is the most easiest way to learn it
http://kidsgrowingstrong.com/germination
note:light is not necessary for seed germination
n the radicle is the embryonic root of the plant and the plumule is from where the shoot emerges
check this http://www.google.com.pk/imgres?um=...w=173&start=0&ndsp=15&ved=1t:429,r:3,s:0,i:75

Can anyone please tell me about differences b/w DNA and RNA and translation and transcription? Is it even in our syllabi?

DNA = Deoxyribonucleic Acid
RNA = Ribonucliec acid!!!

So its LOUDNESS, that is to say amplitude :O Thanks anyway...

 

[ashiqbal]

Ok v.v important:
i need three to four points of why mother's blood is not continuous with the fetal blood? 2 points i know are:

1. the difference in pressure
2. difference in blood group(all that co-aglutination and stuff

so tow or at least one more point!
