Protists are unicellular whereas Fungi are multicellular.
Answer:
Cohesion is an attractive force between same kind of molecules while adhesive force exists between different kinds of molecules. When water moves inside vascular tissue they contain cell sap. It is these two forces which keep materials in cells and water can easily move them to different parts where they are necessary.
Answer:
The statistics given has shown that night-migrating birds are driven by autonomous circadian clocks which is made possible by sunset cues. This timekeeping that is the autonomous circadian clocks system is probably the key factor in the overall control of nocturnal songbird migration.
Explanation:
If the concentration of molecules outside the cell is very high relative to the internal cell concentration, the rate of diffusion will also be high. If the internal and external concentrations are similar (low concentration gradient) the rate of diffusion will be low.
Answer:
<h2>50% are brown.</h2><h2>50% are green.</h2><h2 />
Explanation:
Given;
B allele is for brown color, so B = brown,
br= red,
bg= green,
by= yellow.
B is dominant over all;
bg is dominant over by;
br is dominant over bg;
by is recessive to all other alleles.
Here, cross between brown (B/by) and pure green (bg/bg).
B/by× bg/bg
progeny
Genotype= B/bg, B/bg, by/bg and by/bg.
Phenotype= B/bg= brown;
by/bg= green
So, 1/2 are brown and 1/2 are green.
