I think the answer is B; that’s assuming that the other allele of the heterozygous brown eyed man is coding for blue eyes. If it’s not then my answers wrong. Tell me if you don’t understand or you need a step by step explaination
Material through which water flows is permeable. This material can be either natural or artificial. Naturally permeable material can be clean sand and gravel for example, or a sandstone and in the latter case the sandstone can have both porosity which is not synonymous with permeability as the pores must be connected to be permeable. An impermeable membrane could be used to line ditches for example to prevent leakage near mines.
The answer would be C.
Nonpolar molecules cannot form hydrogen bonds that polar molecules can. Interactions between nonpolar molecules are very weak thus D is wrong. And water can climb up inside plants and has adhesion and cohesion because of it’s strong hydrogen bonds.
