As red blood cells pick up carbon dioxide from tissues to be moved to the lungs, the carbon dioxide reacts with water to form carbonic acid. Carbonic acid is transported to the lungs where it is converted back to carbon dioxide and water, and the carbon dioxide can then be exhaled. Carbonic anhydrase increases the rate of production of carbonic acid from only 200 molecules of carbonic acid to 600,000 molecules being formed per hour. This increase in reaction rate is necessary for the process to be biologically useful. Carbonic anhydrase is not changes in the reaction. Carbonic anhydrase is a(n)

B. Midwestern farmers often hunt coyotes hat harass their livestock

C. African elephants are hunted for the ivory of their trunksD. Feral cat populations are hunted and killed in all urban

and semi-urban areas to reduce the spread of disease

Hunting is one methods of wildlife management, allowing populations of some species to be reduced before they reach or exceed carrying capacity and begin to damage their environment. For instance, snow geese have exceeded their carrying capacity and begun to seriously damage the arctic and sub-arctic salt-marsh habitat that is their summer foraging ground. This prompted President Clinton to sign legislation intended to reduce the population of the geese by 50% over 5 years. However, other kinds of hunting are not intended to control animal populations. Choose the hunting scenario that is not an ecological control tool.

A. Crossing over with genetic recombinationB. Independent assortment at the time of meiosisC. Increasing the cell population by mitosisD. Combination of parental genetic backgrounds at

fertilization

Sexual reproduction encourages genetic variation in three ways. Which of the following is not a feature of sexual reproduction that promotes new genetic combinations?

A. The spine and the thorn are analogous structures, so we can conclude that the cactus and the rose did not evolve from a common ancestor

B. The spine and the thorn are vestigial structures, so we can conclude that the cactus and the rose evolved from a common ancestor

C. The spine and the thorn have separate functions, so that they are not homologous and provide no evidence to support a common ancestor

D. The spine and the thorn have similar appearances, so we can conclude that they evolved from a common ancestor

The spines of cactus are modified leaves. The thorn of a rose is a modified branch. What does this suggest about the evolution of these two families of plants?

A. Divergent evolutionB. ExtinctionC. Co-evolutionD. Convergent evolution

The ancestors of polar bears became separated from brown bears when they moved from the mainland to the Arctic ice. Since they were in different environments, the traits selected in the Arctic population were different than the traits selected in the land population. Eventually, the two populations could no longer interbreed. Today, we call the descendants of the Arctic ice population polar bears and the descendants of the mainland population brown bears. What is this phenomenon of the one group of organisms separating and forming two reproductively isolated groups known as?

A. Some kinds of wasp lay their eggs on the bodies of aphids; the larvae then eat the aphid as they grow

B. Lacewing larvae will eat almost any other insect of suitable size, including caterpillars and aphids

C. Both adult ladybugs and ladybug larvae eat aphids and mites

D. Army ants swarm through a habitat, eating every insect species they encounter

Biological pest control involves the use of one or several kinds of insects to act as predators or parasites to other insect species that damage a particular crop. This must be done without causing adverse effects to humans, animals, or surrounding environment. Which of the following insect activities would be least useful as a biological control mechanism for common agricultural pests?

A. Sickle-cell anemia provides protection to all West Africans to differing degrees

B. Sickle-cell may save some individuals from death by malaria, but they will have other medical issues resulting form the sickle-cell anemia itself

C. Sickle-cell causes red blood cells to contract malaria D. Sickle-cell will save some individuals from death by

malaria and then pass out of the blood stream

Sickle-cell anemia, a recessive genetic disorder causes red blood cells to take on a crescent shape. The movement of the damaged cells through small blood vessels and capillaries is quite painful. However, there is evidence to suggest that this disease offers some protection against malaria, a disease that also infect the red blood cells. Malaria is common and usually deadly in West Africa. Based on this information, what is an accurate conclusion regarding the effect of sickle-cell on West Africans?
