Answer: The frequencies of alleles in this new dodo population may be very different from the net Day frequencies from 1,000 years ago.
Explanation: Due to the very low population of dodo, the frequency of alleles in this new dodo population may be very different from the frequencies expected in larger (now non-existent) populations.
Answer:
A hydraulic conductivity of 7.6 ft/day converts to 2.3 m/day.
Explanation:
This problem can be solved as a simple rule of three, with the mathematical conversion from feet to m.
Each ft has 0.3048m. So how many m are there in 7.6ft?
1 ft - 0.3048m
7.6ft - x m
So
A hydraulic conductivity of 7.6 ft/day converts to 2.3 m/day.
Answer:
150 million years old
Explanation:
If we have an isotope that has a half-life of 50 million years, we need just need to divide the numbers in order to get to one eight of the full number, than multiply it by 50 million in order to get the result.
If one half is 50 million years, than dividing one more half, which will gives one fourth of the total, will brings us to 100 million. Dividing the one fourth by two will leads to the one eight of the full number, and adding 50 million more years, we get 150 million years. So the rock in question has 150 million years of age.
The basic layout of the current periodic table has:
Columns known as groups, the elements inside each of which having similar properties.
Rows known as periods. The elements in a given period have the same number of electron shells.
