Question of the Day #7

The answer to the previous question is: A centromere is the point of attachment of two sister chromatids in any cell, arising during the process of cell division. A centrosome is a cell organelle initiating cell division in animal cells. For further points of differences between the two, you may go through Ishan’s answer in the comment section of the previous post.

Congratulations to Ishan and Smriti for answering correctly! 🙂

Question of the Day: What is ‘feedback mechanism’?

Leave your answers in the comment section below and we will get back to you as soon as possible! Keep yourself updated! 🙂

Question of the Day #6

Without any further delay, the answers to the previous question are: (a)Hydrogen Sulphide (b) Nitrogen Dioxide or Bromine (c) Carbon Dioxide (d) Chlorine (e) Hydrogen (f) Carbon Dioxide (g) Ammonium Chloride.

Please note the change in the sequence of letters. By mistake, I had previously repeated the ‘(c)’.

Apparently, Shrish is the only reader who offered ‘bromine’ as a second answer in (b) so hats off to him! Ishan, meanwhile, gave a precise answer for (g). They both got all attempted answers correct! Congratulations to them and everyone else who got most answers correct. 🙂

Regarding the current question (f), ammonia cannot be an option as fire extinguishers include ammonium phosphate to extinguish a flame and not merely ammonia. Hence, carbon dioxide is the ideal answer.

Question of the Day: Differentiate between ‘centromere’ and ‘centrosome’.

Leave your answers in the comment section below and we will get back to you tomorrow with the correct answer! Thank you and keep visiting! 🙂
