A population of wolves migrates north in search of food. As the wolves travel, they enter a region that has long, snowy winters. Some of the wolves have an allele that gives them white coats. This makes them better able to sneak up on prey.

1. Which type of wolf is selected for in this new ecosystem?

2. Has genetic diversity helped or hurt the survival of the wolf population? Explain.

Base your answers the questions below on the information provided and your knowledge of biology. Ocean-dwelling (marine) iguanas and land iguanas inhabit the Galapagos Islands. Some scientists believe that both types of iguanas diverged from a common ancestor. Marine iguanas eat algae. Land iguanas feed on cacti. Algae are more abundant in the ocean than cacti are on the islands. Both species lay their eggs in the sand. Rats, cats, and goats have been introduced to the islands by humans. Rats feed on iguana eggs, cats eat baby iguanas, and goats eat cacti. • Which population of iguanas, marine or land, would you expect to be larger? Support your answer. • Identify one technique that can be used to support the conclusion that these two species of iguana developed from a common ancestor.

A 77-year-old man presents with left-sided chest pain, headaches, night sweats, a burning sensation in his hands and feet, and shortness of breath. He began having headaches 2 days ago, and his symptoms have progressively worsened. On exam, the patient is a thin ill-appearing man. His spleen is palpated 8 cm below the costal margin, and the liver 5 cm below the costal margin. Laboratory analysis shows that his red blood cell count is elevated, and he has a decrease in plasma volume. White blood cells and platelets are within normal limits. Appearance of the red blood cells is normal. Arterial blood gas analysis shows an O2 saturation of 94% on room air. What is the most likely cause of this patient's symptoms?
a. Chronic myelogenous leukemia
b. Polycythemia vera
c. Thrombocytopenia
d. Iron-deficiency anemia
