Select the statement(s) that support bird beak adaptations as supporting evidence for the theory of natural selection.
-The top bird with a beak adapted for
insect eating would not succeed on a
Galapagos Island with little insects but
plentiful seeds.
-The middle bird with a woodpecker
beak adapted for seed eating most
likely could dig deeper for larger,
harder covered insects more
successfully than the top bird with the
insect eating beak.
The bottom right bird with a beak
adapted for seed eating would succeed
on a Galapagos Island with plentiful
insects but little vegetation.
The bottom right bird with a beak
adapted for seed eating would succeed
on a Galapagos Island with plentiful
vegetation and few insects.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
