Answer the following question given this paragraph: Urethra The urethra transports urine from the bladder to the outside of the body for disposal. The urethra is the only urologic organ that shows any significant anatomic difference between males and females; all other urine transport structures are identical (Figure 25.3). Q: The urethra transports urine from what organ to the outside of the body for disposal? Choices: - heart - lungs - brain - bladder A:
bladder
Answer the following question given this paragraph: An estuary is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the ocean. Estuaries can be thought of as the most biologically productive regions on Earth, with very high biodiversity. Estuaries are zones where land and sea come together, and where fresh and salt water meet. Q: What can be thought of as the most biologically productive regions on earth? Choices: - swamps - forests - coasts - estuaries A:
estuaries
Q: Answer the following question given this paragraph: Reproduction Fungi reproduce sexually and/or asexually. Perfect fungi reproduce both sexually and asexually, while the so-called imperfect fungi reproduce only asexually (by mitosis). In both sexual and asexual reproduction, fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Fungal spores are smaller and lighter than plant seeds. The giant puffball mushroom bursts open and releases trillions of spores. The huge number of spores released increases the likelihood of landing in an environment that will support growth (Figure 24.6). Q: What do all respiratory diseases affect? Choices: - liquid exchange process - helium exchange process - transit exchange process - gas exchange process A:
A: gas exchange process
Question: Answer the following question given this paragraph: 22.1 Introduction Viruses are the smallest biological particle (the tiniest are only 20 nm in diameter). However, they are not biological organisms so they are not classified in any kingdom of living things. They do not have any organelles and cannot respire or perform metabolic functions. Viruses are merely strands of DNA or RNA surrounded by a protective protein coat called a capsid. Viruses only come to life when they have invaded a cell. Outside of a host cell, viruses are completely inert. Since first being identified in 1935, viruses have been classified into more than 160 major groups. Viruses are classified based on their shape, replication properties, and the diseases that they cause. Furthermore, the shape of a virus is determined by the type and arrangement of proteins in its capsid. Viruses pathogenic to humans are currently classified into 21 groups. Viruses can also attack bacteria and infect bacterial cells. Such viruses are called bacteriophages. Q: The shape of a virus is determined by the type and arrangement of proteins in its what? Choices: - enamel - anode - nuclei - capsid A:
Answer: capsid

Answer the following question given this paragraph: Like roots, the stems of vascular plants are made of dermal, vascular, and ground tissues. Q: In vascular plants, what two basic structures are made of dermal, vascular, and ground tissues? Choices: - stems and flowers - roots and seed - fruits and nuts - roots and stems A:
**Answer**
roots and stems
Answer the following question given this paragraph: Some solutes, such as sodium acetate, do not recrystallize easily. Suppose an exactly saturated solution of sodium acetate is prepared at 50C. As it cools back to room temperature, no crystals appear in the solution, even though the solubility of sodium acetate is lower at room temperature. A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal. The seed crystal provides a nucleation site on which the excess dissolved crystals can begin to grow. Recrystallization from a supersaturated solution is typically very fast. Q: What is used to recrystallize excess dissolved solute in a supersaturated solution? Choices: - starter crystal - energy crystal - fertilizer crystal - seed crystal A:
seed crystal
