Answer:
These creatures depend on the sea water for nutrients, protection and to move about. At low tide,many of these creatures are exposed to the air, leaving them at risk of predator attacks andoxygen depletion. The whole eco-system of the tide pools would simply not exist without theconstant movement of the tides
Explanation:
Scientists can determine relatedness amongst organisms via way of means of evaluating partial amino acid sequences. The desk suggests 4 partial amino acid sequences from 4 organisms.
<h3>What is determine relatedness?</h3>
Presently, the maximum customary technique for building phylogenetic timber is a technique referred to as cladistics. This technique kinds organisms into clades, organizations of organisms which are maximum intently associated with every different and the ancestor from which they descended.
Scientists can now decide relatedness via way of means of evaluating the frequency of nucleic acid bases (the G + C content), carry out nucleic acid hybridization to decide the diploma to which DNA sequences are the same, carry out nucleic acid sequencing, or carry out different superior molecular techniques.

Answer:
See the answer below
Explanation:
1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.
2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.
3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:
AA x aa
Aa Aa Aa Aa
All the F1 offspring will appear tall and their genotypes would be heterozygous.
4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>
5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>
