Answer:
genetic modification competitors increase
Explanation:
The fish developed the gills because of <em>genetic modification</em>. Because the fish are now able to swim in deep water, their <em>competitors</em> in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will <em>increase</em>.
Explanation:
an allele is an alternative form of a particular gene whereas a trait is the character that is determined by the allele.
The correct answer is by facilitated diffusion.
The procedure of continuous passive transport of ions or molecules through a semi-permeable membrane with the help of particular transmembrane integral proteins is known as facilitated or passive-mediated transport or facilitated diffusion.
It is a modification of osmosis incorporating a proteinaceous channel via which an extracellular solute can enter a cell in the absence of energy.
