Answer the following question given this paragraph: Several common human diseases are caused by fungi. They include ringworm and athlete's foot, both shown in Figure below . Ringworm isn't caused by a worm. It's a skin infection by a fungus that leads to a ring-shaped rash. The rash may occur on the head, neck, trunk, arms, or legs. Athlete's foot is caused by the same fungus as ringworm. But in athlete's foot, the fungus infects the skin between the toes. Athlete's foot is the second most common skin disease in the U. S. Q: Ringworm and athlete's foot are common human diseases caused by types of what? Choices: - viruses - multicellular bacteria - acids - fungi A:
fungi
Answer the following question given this paragraph: The three types of muscles in the body include skeletal muscle, smooth muscle, and cardiac muscle. Q: Smooth, cardiac, and skeletal are all types of what? Choices: - hormones - bone - teeth - muscle A:
muscle
Q: Answer the following question given this paragraph: Part of a cycle that holds an element or water for a long period of time is called a reservoir . The ocean is a reservoir for water. The deep ocean may hold water for thousands of years. Q: What is part of a cycle that holds an element or water for a long period of time called? Choices: - homeostasis - a ditch - a holding tank - a reservoir A:
A: a reservoir

Answer: rising

Answer the following question given this paragraph: Many of the organisms that made up the Pleistocene megafauna went extinct as conditions warmed. Some may have been driven to extinction by human activities. Q: Warming conditions and, perhaps, human activities contributed to what fate of many organisms of the pleistocene era? Choices: - overpopulation - accumulation - evolution - extinction A:
**Answer**
extinction

Answer the following question given this paragraph: Phylogenetic Trees Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. In other words, a "tree of life" can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms (Figure 20.2). Unlike a taxonomic classification diagram, a phylogenetic tree can be read like a map of evolutionary history. Many phylogenetic trees have a single lineage at the base representing a common ancestor. Scientists call such trees rooted, which means there is a single ancestral lineage (typically drawn from the bottom or left) to which all organisms represented in the diagram relate. Notice in the rooted phylogenetic tree that the three domains Bacteria, Archaea, and Eukaryadiverge from a single point and branch off. The small branch that plants and animals (including humans) occupy in this diagram shows how recent and miniscule these groups are compared with other organisms. Unrooted trees don't show a common ancestor but do show relationships among species. Q: What tool do scientist's use to show the evolutionary pathways and connections among organisms? Choices: - conceptual tree - superficial tree - photogenetic tree - phylogenetic tree A:
(A).
phylogenetic tree
