Explanation:
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
Answer:
Cerebral Nuclei.
Explanation:
Cerebral nuclei refers to one of three components of the cerebrum. It is a composite structure of the end-brain defined on the basis of origin from the ventricular ridge of the embryonic Encephalon. It is a lusters of gray matter that contain neuron cell bodies and lie within masses of white matter.
