The answer would be -- A. Cenozoic
Answer;
b. Their ability to pass on genetic information.
Explanation;
-Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure.
-They exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings.
The guinea pig and the raccoon are both members of :
The eukarya domain, the kingdom of animals, the chordates and the mammal class.
After the level of class (Mammalia), they start to belong to different groups.
The guinea pig belongs to rodents and the raccoon belongs to the carnivores.
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
