Bacteria, viruses, fungi, Protozoa, and Helminths
The answer is chromosome
The chromosome is densly packed DNA.
Answer:
The answer is very likely C.
Explanation:
This becomes easy once we remember that DNA and RNA are not identical - which is why they have different names, RNA = 'ribo', DNA = 'deoxy.' This eliminates choice (A). While they are different, they are not incredibly different - DNA and RNA are both made up of nucleotides - they are not however, made up of Amino acids. Amino acids are what they can <em>code</em> for, and subsequently create proteins during protein synthesis. This helps us eliminate (B). Finally, we know that in order for something to have base <em>pairs</em> it needs to be double stranded - which RNA is not. Which means that because RNA is not double stranded (its singly stranded) that the answer cannot be (D). Leaving us with the only plausible option; (C).
Answer:
The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike". ( D )
Explanation:
The property of a neuron's action potential that determines the maximum firing rate is ; The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike".
The firing rate of a neuron defines the number of spikes that a neuron can produce per second and for a typical neuron that number is from 1 spike to 200 spikes per second
Multi cellular organism is an organism that consists of many cells unlike unicellular which consists of a single cell.
The first picture is of multicellular organisms.
The second, for more information, is of unicellular organisms
