Answer:
Option B, Mechanical Isolation
Explanation:
Mechanical isolation is a phenomena which prevent species from mating each other.
In mechanical isolation, species have different physical structure due to which they are unable to interbreed.
For example - In snails, two certain species are unable to mate as the shell of one is coiled in the same direction as that of shell of other. Hence, two right coiled snails cannot breed with each other. The same applies to the left side tailed species.
Hence, option B is correct
The Ordovician is best known for its diverse marine invertebrates, including graptolites, trilobites, brachiopods, and the conodonts (early vertebrates). A typical marine community consisted of these animals, plus red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods.
Answer:
The conversion of O-acetylserine into N-acetylserine is produced
Explanation:
The data have high precision but poor accuracy because of a systematic error. Thus, the correct option is A.
<h3>
What is systematic error?</h3>
An error that is not caused by chance, but rather by a system-wide inaccuracy (in terms of observation or measurement).
The accuracy of a value refers to how close it is to its genuine value. An arrow's proximity to the bull's-eye center is an example. A measurement's precision refers to how repeatable it is. A systematic error has occurred.
