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.
Answer:
Pulmonary embolism.
Explanation:
In the above scenario, this could be pulmonary embolism case because Mr. Jackson's condition and their symptoms shown towards the pulmonary embolism.
In pulmonary embolism, an artery present in the lungs block by a substance that can be transfer from any part of body through blood circulation and stuck in the artery of lungs and due to this shortness of breath, sever chest pain during coughing or breathing in.
So, the above condition of Mr. Jackson shows pulmonary embolism.
The population growth or population recovery will be an exponential growth curve. The linear fit on the given data will help model the recovery of the population in future time. The attached image shows the linear fit and its extrapolation till the year 3000. The linear fit gives a good underestimate of the population in the years after 2530. Hence the answer is D. a date in the distant future.
Neanderthals have contributed approximately 1-4% of the genomes of non-African modern humans, although a modern human who lived about 40,000 years ago has been found to have between 6-9% Neanderthal DNA
