A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 5 million years. How many years
zubka84 [21]

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.

If you were planting a vegetable garden, what should you consider for the time of planting?
zvonat [6]

When planting vegetables it is very important to know the climate of the area, its usual patterns, and how will that affect the growth and development of the crops. The soil quality too is very important, as it is the basis for the development of the root-stock of the crops.

If we have a temperate type of climate, than we have four different seasons, meaning different weather patterns throughout the year. We can take onions, radish, and peppers as vegetables of choice. The onions can be planted in mid-autumn, as they will need more moisture, and they are resilient to low temperatures, thus will not have problems in the winter, and in the spring they will already have the basis so will grow quickly and be larger. The radish can be planet in late winter or early spring, in a period when there is more precipitation. It is not a vegetable that likes high temperatures, so with its quick development, it will be able to develop the tuber by late spring. The peppers can not sustain low temperatures, so they should be planted in late spring. They also like warm weather and lot of water, so it will be needed to water them a lot in the hot and dry period. They will manage to develop and produce the vegetables by the end of the summer, thus not getting damaged by the cold nights in the autumn.
