If the egg was weighed halfway between being laid and hatching, how would you expect that weight to compare to the weight of the newly hatched chick?
A) The egg would weigh more at this midpoint than when newly hatched because, during development, the chick gains new parts.
B) The egg would weigh more at this midpoint than when newly hatched because it is taking in oxygen.
C) The egg would weigh less at this midpoint than when newly hatched because the shell wears away over time.
D) The egg would weigh less at this midpoint than when newly hatched because some of the mass of the egg would be released through cell respiration.

Q: Please read the following scenario to answer the following questions. In May 2014, the European Union (EU) published a report of population structure and aging data that described growing trends of low birth rates and longer life expectancies in the EU. In their report, the EU described that, due to these trends, some EU member states are beginning to demonstrate a population structure with many much-older individuals. Why might this changing population structure be a concern for EU leaders? A) Eventually greater resources will be needed to support a much larger and older generation, and this burden will fall on an increasingly smaller workforce. B) Eventually the EU population will exhibit a Type III survivorship curve. C) Eventually intraspecific competition for resources amongst the older members of the population will lead to a decrease in food and water availability. D) Eventually individuals of reproductive age will face a boom-and-bust population cycle.
Q: Please read the following scenario to answer the following questions. CO2 is not the only greenhouse gas that impacts global climate change. Other greenhouse gases (GHGs) may be equally or more effective than CO2 at trapping heat on Earth. Climate scientists determine how much a GHG may impact global warming based on two factors: the efficiency with which a GHG absorbs energy (i.e. traps heat on Earth) and the length of time (in years) that the gas remains in the atmosphere. A unit of measurement called the Global Warming Potential (GWP) is used to describe how much energy a GHG absorbs over a specific period of time (100 years is a standard time frame). All GWP values of GHGs are compared to the GWP of CO2, which is given a value of 1. has a GWP over 20 times higher than CO2. However, CH4 emitted today lasts for only about a decade in the atmosphere, while the GWP of CO2 can last for thousands of years. What is a possible reason that CH4 can have such a high GWP as compared to CO2? A) The 100-year time frame is too short of a time frame to compare CH4 and CO2. B) CH4 absorbs more energy than CO2. C) CH4 is less efficient at trapping heat on Earth. D) CH4 is not a proven greenhouse gas.

Q: Read the following scenario to answer the following questions. People utilize plants to meet many everyday needs, including food, fiber, and building materials. However, not many of the over 300,000 known species of plants are used by people. One species with a lot of future promise is the jatropha tree. This species is native to Central America and is now found throughout the tropics. Many people believe the jatropha could help alleviate poverty in many areas of the world, as the seeds produce an oil that can be used for cooking, lighting, or generating electricity. This oil can also be mixed with diesel fuel or petrol to produce a biofuel. Mature trees produce between 5 and 15 kg of seeds per year and can live more than 30 years. However, critics argue that planting the jatropha tree will take land needed for food production, which will in turn harm the poor. What would NOT be an advantage of using oil from jatropha seeds? A) The oil is considered a renewable resource. B) The oil can be used for generating electricity. C) The oil can be used as a biofuel. D) Growing jatropha tress to produce oil may lower food production.
Q: What important role do fungi play in many ecosystems? A) They decompose organic material. B) They pollinate plants. C) They disperse the fruits of angiosperms. D) They perform photosynthesis.
