Q: Answer the following question given this paragraph: 19.3 The Human Population Earth's human population is growing exponentially. Humans have increased their carrying capacity through technology, urbanization, and harnessing the energy of fossil fuels. The age structure of a population allows us to predict population growth. Unchecked human population growth could have dire long-term effects on human welfare and Earth's ecosystems. Q: Human population is growing exponentially and humans have increased what normally limiting factor through technology, urbanization, and harnessing the energy of fossil fuels? Choices: - zero population growth - mass extinction - habitat loss - carrying capacity A:
A: carrying capacity

Q: Answer the following question given this paragraph: Graphs are very useful tools in science because they display data visually. Three commonly used types of graphs are bar graphs, circle graphs, and line graphs. Each type of graph is suitable for a different type of data. Q: Bar, circle, and line are examples of what kind of data visualization? Choices: - maps - spreadsheets - formulas - graphs A:
A: graphs

Q: Answer the following question given this paragraph: Momentum can be calculated by multiplying an object's mass in kilograms (kg) by its velocity in meters per second (m/s). For example, assume that a golf ball has a mass of 0.05 kg. If the ball is traveling at a velocity of 50 m/s, its momentum is:. Q: What can be calculated by multiplying an object's mass in kilograms (kg) by its velocity in meters per second (m/s)? Choices: - energy - height - ground speed - momentum A:
A: momentum

Q: Answer the following question given this paragraph: The place where the axon of one neuron meets the dendrite of another is called a synapse . Synapses are also found between neurons and other types of cells, such as muscle cells. The axon of the sending neuron does not actually touch the dendrite of the receiving neuron. There is a tiny gap between them, the synaptic cleft ( Figure below ). Q: What is the place called where the axon of one neuron meets the dendrite of another? Choices: - uptake - neurotransmitter - apoptosis - synapse A:
A: synapse
