4 mutations occured, as four letter we're different 25 million years later. Over one hundred years we can expect it to mutate at the sane rate, but 4 times longer. 4 time 4 is 16 mutations over 100 million years
The best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.
<h3>What is the meniscus of a liquid?</h3>
The meniscus of a liquid is a curved that occurs at the top of a liquid placed in a container as a result of the attractive forces between the molecules of a the liquid.
Polar substances such as water have a concave meniscus as they dip downwards.
Therefore, the best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.

Check your chemistry textbook (or class notes) concerning molar mass, then look up the value for oxygen.
Then divide Avogadro’s number into the given amount of atoms, to find the number of moles.
Then combine this result appropriately with the molar mass, and voilà!
…Then reconsider posting homework questions without showing the work you have already done.
Answer:
The disadvantages or the limitations are as follows:
Dot structures: based on an empirical trend “atoms like octets”, not a rigorous description of the true nature of electrons
Arrow and line diagrams: Does not say much of the possible properties of the molecule.
Written electron configurations: no 3D representation of the molecule or the atom
