Julli [10]

Answer:

Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.

"it is possible to combine two or more plant proteins with different essential amino acids to yield a complete protein."
leonid [27]
Yes i believe it is possible. Complete proteins are proteins with all the indispensable amino acids present in proper proportions; for example in foods like eggs, meat, fish, milk. Incomplete proteins on the other hand are food proteins that contain a limiting amount of one or more indispensable amino acids needed for growth; for example corn tortillas are lacking in lysine. It is possible to make a complete protein by combining together two incomplete protein foods in the same meal.

DENIUS [597]

Answer:

This difference indicates that the results are precise but not accurate .

Explanation:

Precise results are those that are very close to the actual result, but do not achieve exactly the same result. In addition, this difference between the precise results is exactly the same. We have an example of this in the case shown in the figure above, where the blood pressure readings measured by the cuff differ by 15 points for each reading. This case also shows us that the results are not accurate, because this type of result is one that shows a result exactly the same as the real one.
