There is no specific rate that the bacteria is viral
The new trait appears in a group of previously isolated people is an
example of genetic drift.
<h3>What is Genetic drift?</h3>
This is defined as the random fluctuations in the frequencies of alleles
from generation to generation due to occurring events which makes the
trait to be present or disappear.
The new trait appearing as a result of events such as migration helps to
infer that it is genetic drift.

Answer:
to deliver information about the physiological variable to the integrating center
Explanation:
The afferent or sensory neurons function in transmitting sensory information as action potential from the receptors to the CNS. It synapse with the inter neurons, at the spinal cord, for a bypass to the brain for mediation, The response from the brain is integrated (synapse with the efferent neuron) in the spinal cord and conducted by efferent or motor neuron to the effectors.
Your cardiovascular system is made up of the heart and blood vessels (arteries, capillaries, veins).
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
