I think you forgot to give the options along with the question. I am answering the question based on my knowledge and research. "RNA" is the other kind of molecule that can act as a catalyst for chemical reactions. I hope that this is the answer that you were looking for and the answer has come to your help.
Most sponges I see are some what symmertrical, but not completely. I would say that it is Translational surgery, and the soak up holes repeat them selves.
The first image, because it represents natural gas. Non-renewable gasses are natural gas, petroleum, or even fossil feels
The frequency <em>p</em> of the yellow (A) allele is <em>p</em>= 0.3
The frequency <em>q</em> of the blue (a) allele is <em>q= </em><em>0.7</em>
Hardy–Weinberg equilibrium, states that allele and genotype frequencies in a population will remain constant from generation to generation. Equilibrium is reached in the absence of selection, mutation, genetic drift and other forces and allele frequencies p and q are constant between generations. In the simplest case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes.
p²+2*p*q+q²= 1 p+q= 1 q= 1-p
yellow (p²)= 9%= 0.09 p= √0.09= 0.3
green (2*p*q)= 42%= 0.42
blue (q²)=49%= 0.49 q=1-0.3= 0.7 <em>or</em> q= √0.49= 0.7
<u>At Mount St. Helens, erosion cut through the new volcanic deposits and exposed soil where plants could sprout. Thus in this disturbance, erosion was a positive process for plants, improving habitat. Lakes, streams, and forests responded at different rates after the 1980 eruption.</u>
