Answer:
Explanation:
Vertebrates are members of the kingdom Animalia and the phylum Chordata ((Figure)). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development. The deuterostomes, whose name translates as “second mouth,” consist of two major phyla: Echinodermata and Chordata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
Deuterostome phylogeny. All chordates are deuterostomes possessing a notochord at some stage of their life
Answer:
B. Humans and chimpanzees share a relatively recent common ancestor.
Explanation:
Both the humans and Chimpanzees are the primates that are they belong to the same group called hominids and genus called Homo.
When the DNA sequences of the Chimpanzees and the Humans are sequenced and compared than they showed that 98% of the genome is similar.
In the given question, the single strands of the humans and the chimpanzees base-paired which showed that 98% of the nucleotide sequence is the same. The most possible reason for this similarity is that they both were evolved from the common ancestors and they diverged recently in the past.
Thus, Option-B is correct.
B. Are never going to run out
