True, this is exactly what convergent evolution is
Answer:
either RNA or DNA
Explanation:
The advancement of biomedical research techniques and molecular biology has led to the observation of the close relationship between certain viruses and some cancers in various animals. Thus, it has been shown that several DNA and RNA viruses are oncogenic in a wide variety of animals, from amphibians to primates, and there is growing evidence that some human cancers have a viral origin.
Based on this, we can conclude that oncogenic viruses can be composed of DNA or RNA.
Microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes.
So from your choices most likely it will be A) ancient bacteria :)
The top layer of the brain, responsible for higher-level mental processes, is the neocortex because the neocortex comprises the largest part of the cerebral cortex, which makes up approximately half of the volume of the human brain. It is responsible for the neuronal computations of awareness, thought, perception, and episodic memory.
Therefore, The neocortex is the top layer of the complex brain that commands higher functions related to the mental processes such as cognition, sensory perception, and emotion. Although the neocortex consists of neuronal cell bodies or grey matter and unmyelinated fibers that surround the deeper white matter in the cerebrum, that helps for higher-level mental processes.
