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:
(Answer)
carrying capacity
Ques: Answer the following question given this paragraph: Building Phylogenetic Trees with Analysis of DNA Sequence Alignments All living organisms display patterns of relationships derived from their evolutionary history. Phylogeny is the science that describes the relative connections between organisms, in terms of ancestral and descendant species. Phylogenetic trees, such as the plant evolutionary history shown in Figure 26.7, are tree-like branching diagrams that depict these relationships. Species are found at the tips of the branches. Each branching point, called a node, is the point at which a single taxonomic group (taxon), such as a species, separates into two or more species. Q: What is the science that describes the ancestral and descendant connections between organisms? Choices: - experimentally - organic science - polygamy - phylogeny A:
Ans: phylogeny
(Q).
Answer the following question given this paragraph: An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave. Q: An electromagnetic wave begins with what movement by an electrically charged particle? Choices: - acceleration - diffusion - momentum - vibration A:
(A).
vibration
Ques:Answer the following question given this paragraph: Toxic waste must be disposed of properly or there can be serious consequences. Now, your waste should not be as colorful or toxic as shown here (if it is, get yourself to a doctor as soon as possible), but it still needs to be removed from you. And that is the role of the excretory system. The excretory system gets rid of waste and excess water. Q: What system of the body is responsible for ultimately ridding it of waste and excess water? Choices: - circulatory system - digestive system - respiratory system - excretory system A:

Ans:excretory system
Ques:Answer the following question given this paragraph: Decomposition of dead organisms and organic wastes releases carbon back to the atmosphere, soil, or ocean. Q: What does the decomposition of dead organisms and organic waste release into the atmosphere, soil, or ocean? Choices: - nitrogen - oxygen - hydrogen - carbon A:

Ans:
carbon
