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.
The sickle cell pattern based on the family history of Ashleigh isan:
- Autosomal recessive pattern
Based on the given question, we cam see that in the medical history of Ashleigh's family, most of them have had the sickle cell disease which includes her grandmother, one of her uncle's six children has it too, but her father and grandfather did not have the disease.
With this in mind, the inheritance of the sickle cell disease in the family of Ashleigh is one which is autosomal recessive as it affects some people and doesn't affect others because of the pairing of the chromosome which <em>contains the sickle cell trait.</em>

Answer:
Habitat/Environment. Either can be right
The statement that describes this prediction is as follows:
- The prediction is useful because it explains what observations will be made if a hypothesis is true.
Thus, the correct option is D.
<h3>What is Herbicide?</h3>
Herbicide may be defined as a chemical agent that is responsible for destroying or inhibiting the growth of a particular plant as compared to the normal one.
The projection is necessary because it supports the product after a one-year duration. So for example, if after one year there is undoubtedly a reduction in the intermediate height of the tomato plants, then we can absolutely say that it is because of the existence of NoGro herbicide which is supplied in water.
Therefore, it is well described above.

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.
- The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
- As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
- While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
- This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
- At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.
