"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.

because it benefits the soil. the long alfalfa stand life also gives the soil a chance to rest from frequent field crop rotations, helps provide nitrogen for subsequent crops, and improves soil tilth. this helps prevent pesticide and sediment movement to natural waterways.

good luck :)

have a great day !!

Answer:

C. Disruptive Selection

Explanation:

Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.  

The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.  

The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.  

Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators
