SamanN:

Thank you the point he made is, ice float on water cos of it's lower density; higher volume. Please check the past question year '97 Q25. What answer do you get?

You mustn't forget that water and steam are two different states of matter, so if you're referring to water; ice is less dense than water--> the reason why ice cubes will float in your cup of water. Steam is the least dense of them all.
The answer to that question is A.

The following events take place during conjugation in spirogyra 1. The protoplasm of each of the conjugating cell separate from the cell wall to form a Gamete; the gamete of one filament passes through the conjugation tube to meet the gamete of the other filament 2. The zygote soon become surrounded by thick brown wall to become zygospore which burst after a short rest and germinate to produce a new filament 3. The nuclei of the gametes fuse to form a zygote 4. The protuberance meet and where they touch the cell-wall disappear so that a conjugation tube joining the two cell is formed 5. protuberance appear on the wall of the cell of two filament of spirogyra lying side by side opposite one another. Now what is the correct sequence in which the above sequence occur?

A. 1,2,3,4,5
B. 1,2,4,5,3
C. 3,4,5,2,1
D. 5,4,1,3,2
E. 5,4,3,1,2

In which of the following groups of organisms do all the members have asexual method of reproduction?

A. A geen filament algae, a flowering plant and a bird
B. A toad (or frog) , ameoba and mucor ( penicillium)
C. A flowering plant, tape worm (or ascaris) and a green filamentous algae
D. Mucor (or penicillium), a bird and a toad (or frog)
E. Ameoba, mucor (or penicillium ) and a green filamentous algae

The answer to that question is A.

Option A, for volume to decrease it means corresponding increase in density. With what you've explained density in decreasing order would be water➡ice➡steam. Is that it?

Very much so

there is nothing to xplain bros it's just a series of how sexual reproductions occur in spirogyra in terms of conjunction. The first thing is that the filament of two opposite spirogyra lying side by side forms a wall where the outgrowth called d protubelance is attached that's 5 followed by 4,1,3,2 where 2 is the final stage

Have u seen the UNN medicine result?? Oboy...u have to be Albert Einstein and Isaac Newton to make it in that school.

Yeah.....sadly.

You can't dare to blame the students..........I mean who jokes with a medical board exam? Whatever it is, we're only speculating. They know best.

The Bob of a simple pendulum is set into oscillation. When the Bob passes through the lowest point of the motion, the suspended string is cut. If the Bob is then moving with the velocity of 0.8ms-¹ at a vertical height of 5 m above the ground, determine the horizontal distance traveled by the Bob.

Range?? I didn't think to that at first. The "horizontal" made it clearer.
