Based on your knowledge of energy flow through a system and the questions you just answered, what might you conclude about the relative abundances (population sizes) of the Triceratops and Tyrannosaurus? The Tyrannosaurus will have a higher abundance (larger population) than the Triceratops because there is more energy available for it form its primary prey. The Triceratops will have a higher abundance (larger population) than the Tyrannosaurus because there is more energy available for it from plants. Both the Triceratops & Tyrannosaurus will be equally-abundant (equal populations) in the ecosystem. None of these options correctly addresses the question accurately. Neither the Triceratops & Tyrannosaurus will be heavily-abundant (smaller populations) in the ecosystem because they are large animals.

Using the experimental procedures and data, can you determine all statements that are true? Prior to the start of the experiment, the students hypothesized that distilled water was hypertonic to the contents of their eggs. The data supports this. Some of the students suggested that the egg in vinegar had an initial increase in mass and therefore vinegar was hypotonic to the egg's contents during the first 24 hours. T he data supports the hypothesis: the experimental kayro syrup solution is hypertonic to the contents of a raw egg. One student group noted that the vinegar removed the calcium based egg shell. She said this was evidence of a chemical reaction. The data supports that the all of the solutions were hypotonic with the egg. This experiment could be carried out without the vinegar as it was not necessary.

The smallest bee is Trigona minima, a stingless bee whose workers are about 2.1 mm (5/64") long. The largest bee in the world is Megachile pluto, a leafcutter bee whose females can attain a length of 39 mm (1.5"). Members of the family Halictidae, or sweat bees, are the most common type of bee in the Northern Hemisphere, though they are small and often mistaken for wasps or flies.

A temperate deciduous forest is dominated by oak trees, which produce acorns. Populations of deer, black bear, and squirrels all rely on the acorns as a primary source of food.

A) Deer would become less likely to survive and reproduce, so their population would decline. B) Black bears, deer, and squirrels would undergo a mass extinction, so the forest's biodiversity would decrease.

Count Strahd von Zarovich realizes you're the latest incarnation of Tatyana, his consort from another lifetime. In a frenzy, he lunges for your neck and drinks deeply in your blood. Other than becoming a vampire soon, you have lost a lot of blood volume. For now, you live as a human and still have functioning human physiology. Initially, how will this affect your blood pressure, and what is one way your body will react to compensate? Your blood pressure will increase, but your blood vessels will dilate to reduce the total peripheral resistance. Your blood pressure will decrease, but your blood vessels will dilate to reduce the total peripheral resistance. Your blood pressure will stay the same. You're now a badass vampire. Give into the Dark Powers! O Your blood pressure will decrease, but our heart will beat faster to increase cardiac output.

Living Archosaurs: Turtles, Crocodilians, and Birds A. Turtles have bodies encased in a bony shell. 1. The turtle body plan, largely defined by a bony, boxlike shell, has changed little since the group first appeared during the Triassic period 2. The 250 living species of turtles occupy terrestrial, freshwater, and marine habitats. B.Crocodilians are semi-aquatic, predatory archosaurs. C. Birds have key adaptations that reduce body______ and power_____ 1. Birds (Aves) appeared in the Jurassic period as descendants of carnivorous, bipedal dinosaurs. They are members of the archosaurs. Powered flight gave birds access to new adaptive zones, setting the stage for their astounding evolutionary success 2. The skeletons of birds are both lightweight and strong. Most birds have adaptations, such as hollow limb bones with small supporting struts. 3. The bones associated with are generally large. The forelimb and forefoot are elongated, forming the structural support for the wing. Not all birds are strong fliers, like ostriches. 4. Like the skeleton, soft internal organs are modified in ways that reduce weight. Most birds lack a urinary bladder; uric acid paste is eliminated with digestive wastes. 5. All birds also possess which are sturdy, lightweight structures derived from scales in the skin of their ancestors. 6. Other adaptations allow birds to harness the energy needed to power their flight muscles. Their metabolic rates are eight to ten times higher than those of reptiles. They have an efficient respiratory system and four-chambered heart to distribute oxygen.

C. Chondrichthyes includes fishes with cartilaginous endoskeletons. 1. The Chondrichthyes have skeletons composed entirely of ......... which is much lighter than bone. 2.
