Answer & Explanation:
Aquatic plants don't have to deal with drying stress, so, for example, the number of stomas will be lower or even absent. Also, the pressure and temperature conditions underwater are way different than on earth. Therefore, the movement of fluids and metabolic products will be quite different.

Suppose that the proportion of the white crest alleles (r) is given by w and that of the Red crest allele (R) is given by p. We have that p+w=1. The probability that an individual has 2 r alleles is given by w*w since for each allele position the probability is w. Only these individuals have a White phenotype. Hence, we get that w^2=

; the right hand side is the proportion of white birds in the total population. Doing the calculations, this yields that w=0.37. From this, we calculate that p=0.63. The possible ways we have heterozygous individuals are the combinations Rr and rR. The probability for each of those is p*w. Thus, the total probability is 2pw. This is equal to 0.466=0.47. This is the fraction of the future population that is going to be heterozygous assuming the conditions of the Handy-Weinberg equilibrium like random reproductive matching etc.
 
        
        
        
<span>The breakdown would be dacryo-cysto-rhino-stomy. Dacryo means a combining form denoting tears. Cysto denotes the sac. Rhino means nose. Stomy means surgical opening. Therefore, this means to surgically restore tears into the nose from the lacrimal sac when the nasolacrimal duct isn’t working.</span>
