The correct option is A, FEEDING HABIT AND MIGRATION. From the passage given above, it can be seen that seagulls are scavengers, they usually eat from garbage dumps while wild geese eat seeds and insects, thus they differ in feeding habit. In term of migration, seagulls does not follow seasonal pattern of annual migration while wild geese do. These are the contrasts between the two birds.
Answer:
B. <em>The number of grasshopers would go up.</em>
Explanation:
A. is incorrect because it would decrease
C is incorrect because it would also decrease
D is incorrect because snakes dont eat Hawks, but Hawks eat them
B is <em>correct</em> because since snakes would eat the toads, there would be no toads eating grasshoppers
Hope this helps!!!
I believe the answer is comparative anatomy. It is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies, such that both provide evidence of evolution. Similarities in embryos are evidence of common ancestry. For example all vertebrates embryos have gill slits and tails.

Answer:
From the point of view of the type of molecule that is obtained after the degradation of the hydrocarbon skeleton, amino acids can be classified as: glucogenic and ketogenic. The main difference between glucogenic amino acids and ketogenic amino acids is that glucogenic amino acids can be converted to pyruvate or other glucose precursors, while ketogenic amino acids can be converted to acetyl CoA and acetoacetylCoA.
Explanation:
Glucogenic amino acids are amino acids that break down to pyruvate, alpha-ketoglutarate, succinyl Co-A, fumarate, and oxaloacetate and are so named because the synthesis of glucose from these molecules is feasible. Both pyruvate and the Krebs cycle intermediates noted above can be converted to phosphoenolpyruvate and subsequently glucose through gluconeogenesis.Ketogenic amino acids are the amino acids that generate acetyl-CoA or acetacetyl-CoA and are called by this name because they can cause ketone bodies. Since mammals lack the proper enzyme system, these compounds can never be used as precursors for glucose biosynthesis. Of the twenty universal amino acids, fourteen are purely glucogenic and two are purely ketogenic (leucine and lysine). The remaining four (isoleucine, phenylalanine, tryptophan and tyrosine) are glucogenic and ketogenic simultaneously since a part of the hydrocarbon skeleton originates precursors for the biosynthesis of glucose (pyruvate or Krebs cycle intermediates) and the other part acetyl-CoA or acetacetyl -CoA.
