Answer:
Embryological evidence
Explanation:
Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.
D. Fertilization, diploid
During fertilization, the egg and sperm (haploid gametes) fuse and form a diploid zygote. The zygote has 2 complete sets of chromosomes, one from each parent.

The answer is Desalination. Desalination is the process of removing minerals from salt water. Most ocean-water consumption and supply are most likely to be very particular in this places like USA, Europe, Africa and UN. Desalination depends on the capacity and facility of the place.
<span>The disinfectant that was the most effective at controlling the growth of E. coli is disinfectant 2 because of the least number of Ecoli strains found on the dish compared to the other disinfectants. Also dish 4 that cointains water has the most number of Ecoli strains because water is not a disinfectant and Acoi do not die in water alone.</span>
