Different finch species have beaks of different shapes and sizes. what do these beak differences tell us? different finch species have beaks of different shapes and sizes. what do these beak differences tell us? different finch beak shapes are evidence that individual birds changed their beaks so that they could feed efficiently. different finch beak shapes are evidence that all galápagos finches share a common ancestor. different finch beak shapes are evidence that finch species adapted to different environments over many generations. different finch beak shapes are evidence that several finch species with different beak types came to the galápagos islands from the mainland.

Different finch beak shapes are evidence that finch species adapted to different environments over many generations.

The correct answer is C. Different finch beak shapes are evidence that finch species adapted to different environments over many generations.

Explanation:

According to Charles Darwin's proposals related to evolution, organisms that are similar such as birds or finches adapt to environmental conditions over time which explains the differences in terms of the phenotype (observable traits). This occurs in the case of finches beak shapes, as Darwin studied around 15 species of these birds in the Galapagos Islands and found finches have different sizes and beak shapes that were linked to the type of food each species consume and the source of this. Therefore, different finch beak show "that finch species adapted to different environments over many generations".

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
