More than one million years ago, a single species of finch migrated to the Galapagos from the mainland of Central or South America. From this one migrant species at least thirteen species of finch would eventually evolve. This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. In describing the four different finch species we see here, we could also say that filling these varied niches would classify the birds as

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
