bcz fresh water has high concentrate of water and when it is kept in marine water ,Marlene water has low cancentration of water so
when amoeba is kept marine water , amoeba loss water so it shrink in sixe
hope it will help u
which makes it shrink.
The phenomenon is Osmosis.
HERE IS YOUR ANSWER.
Marine water has many types of salts dissolved in it. when amoeba is put in marine water, the salts present in the water make it less concentrated than the concentration of water inside the amoeba cell. When the concentration of water is more inside the cell, then the process of exosmosis takes place because of which the water inside the cells of amoeba go out. This causes amoeba to shrink.
PLEASE MARK MY ANSWER AS THE BRAINLIEST
The phenomenon responsible for it is osmosis
Marine Water is a hyper-tonic solution, so the cells of amoeba shrinks by
Hope this helps.
otherwise it is also influence by oxytocin..
let one of zero of the polynomial be " z"
we need to assume it then the other zero will be negative of it that is -z
equate the quadratic equation to zero as it satisfies it.
4x² - 9 - 8kx = 0
sum of zeroes = -b/a
z+ (-z) = )/4
0 = 2k
2k = 0
k = 0
