Answer: The correct answer for the blank is-  has a Bb genotype, has brown eyes.

As per the information given in the question, blue eyes is a recessive ( depicted by small letter allele, b) trait and brown eyes is a dominant trait (depicted by capital letter allele, B)

A dominant allele ( like 'B' for brown eyes) always masks the expression of recessive allele ( like 'b' for blue eyes).

Heterozygous individual means a particular trait possesses both the alleles ( that is dominant and recessive allele) in the genome, which will produce a dominant trait.

The possible genotypes for brown eyes are 'BB' ( homozygous dominant) and 'Bb' (heterzygous dominant) whereas for blue eyes is 'bb'.

Thus, heterozygous individual has a Bb genotype and will produce brown eyes.

Describe the movement of molecules in the illustration
kvasek [131]

Explanation:

B) Molecules are moving from a higher concentration to a lower concentration

Water molecules from the more concentrated side, will flow into the less concentrated side til they equilibrate- at equilibrium both sides will have the same concentration of solute and water molecules.

In diffusion, small non-charged molecules can move from regions of high concentration to regions of low concentration. This occurs across the phospholipid bilayer, which acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic- this involves the movement of water molecules, gases or other small water-soluble compounds .

In osmosis, molecules of water move across a semi permeable membrane, from regions of high concentration to regions of low concentration until an equilibrium is reached. This always occurs along the concentration gradient within the system.
