what is conduction in terms of cells

In biology, transmission of nerve impulses through neurons is sometimes defined as conduction of nerve impulses

In biology, transmission of nerve impulses through neurons is sometimes defined as conduction of nerve impulses

thank you!but i think it has another meaning,because in some table in an old past paper,they were talking about red blood cells and we had to chooose whether they would conduct or not,even in the syllabus it says we have to know that xylem vessels are used for conduction :S

Which process is involved when translocation takes place in plants, i.e movement of glucose or sucrose from leaves to other parts of plants
Saad Mughal thementor ritx

if thats a question,then its movement of sucrose

part b. marking scheme says liquid around anode goes brown. wont there be bubbles of a colourless gas(oxygen from OH-)?

Basically, conduction refers to the movement of material, for example xylem vessels conduct water and mineral salts. It would be alright to say that phloem conduct glucose, sucrose, etc. Although I haven't read that oxygen is conducted by RBCs. It could be true as well. We have only MCQ paper ahead. It would be sufficient to know that conduction refers to transmission

LOL I meant to ask if this process takes place by diffusion or active transport?

.

lol none of them,you are confusing yourself,this process takes place because all parts of the plant needs glucose for respiration,so just to transport it it needs to be converted by sucrose for the sake of translocation

 

[inquisitiveness]

this is the conduction question im talking about...so you saying that the conduction can refer to different things?

what year is this?

I don't understand, OH should have been discharged as this is not a concentrated solution. What do you say? Saad Mughal

[inquisitiveness]

yeah its of bromine because for anode is affected by the -ve of electrolyte you would write the -ve thing for the substance of electrolyte

 

[inquisitiveness]

if it was dilute you wpuld write OH but if concentrated or aq. its the other thing,not the OH

what??

 

[AhsanAfzal]

what??

aqueous and dilute are same

On another note; the person could turn into anti-matter because of the heat and vanish into thin air.

Do you even know what is anti matter?
