ICSE Class 9th I BIOLOGY I Chapter 7 I Lecture 2 | Experiment oxygen is used up in respiration

[arnav_]

Ma'am please note, a topic was taught wrong. You said that water is used up by seeds in Flask A. But that's not the case. They are already getting water from the wet piece of wool. The level of water rises because oxygen was used up by the germinating seeds and so a partial vacuum was created in flask A. To occupy the space, water level showed a rise.

Ma'am great....
Quite Understanding and not complicated ....
Go ahead....

Well explained! It's very useful for the students who r attending online classes

Whoever think it is good then put a like

Superb 🌺🌺🌺 tomorrow is my biology exam and you have helped me alot .

[ajaisingh]

Thanks for the explanation I was reading this for a long while but I didn't get it but now I got it

[vlxegry]

which one of the flask has a control setup?

[piyalisaha]

[piyushroy]

Mam, please make videos of icse 9 class also that we can also learn as good as class 10 icse you are teaching

[dhairyachhajer]

There is a mistake ma'am. Soda lime is not a mixture of Sodium Hydroxide and Calcium Hydroxide(Slaked Lime). It is a mixture of sodium hydroxide and Calcium oxide.

[viraajdixit]

Ma'am so what is the source of oxygen for these flasks? is it photosynthesising?

[UrfavCheryl]

If there was a live experiment it would be more understandable

[amanpreetkaur]

It really helps me keep making this video's

[manimalask]
