Answer:
Yet even an intact human brain can be biologically alive but incapable of consciousness, or “brain-dead.” Similarly, neither cellular nor viral individual genes or proteins are by themselves alive.
Explanation:
neither cellular nor viral individual genes or proteins are by themselves alive.
Answer:
The answer is b)Betaproteobacteria and e)Gammaproteobacteria
Explanation:
Nitrification, which is defined as the microbial oxidation of ammonia to form a nitrate, plays an important role in the global nitrogen cycle. There are two different groups of bacteria that can oxidize ammonia, as a first step in the nitrogen cycle. These groups are known as the Beta-proteobacteria (genera <em>Nitrosomonas</em> and <em>Nitrosaspira</em>) and the Gamma-proteobacteria (genus <em>Nitrosococcus</em>).
The answer is true! Some mammals even such as penguins only have one child typically.
Answer:
starch is made by plants whie cellulose is not
Answer: All of these choices are correct.
Explanation:
Paired box 6 also known as Pax6 is an evolutionarily conserved transcription factor that plays a major role in the development of the vertebrate eye and the central nervous system. Mutations in mammalian Pax6 are characterized by eye defects, e.g (congenital cataracts, as well as Central Nervous System disorders like microcephaly, dysgenesis, neuron to glia transformations, etc.) Many studies have demonstrated the importance of Pax6 to vertebrate cell differentiation, proliferation, patterning. etc
Pax6 have the tendency to activate multiple genes. For example, if two fly Pax6 genes, eyeless (ey) and twin of eyeless (toy), (initiate eye specification), and, eyegone (eyg) and the Notch (N) pathway, (independently regulate cell proliferation). Pax6 have the tendency to controls eye progenitor cell survival and proliferation through the activation of eyegone (eyg) , thereby indicating that Pax6 initiates both eye specification and proliferation.
Also, Pax6 is considered to be the master control gene for eye development in all seeing animals. In vertebrates, it is required not only for lens/retina formation but also for the development of the central nervous system.
