Q: What do fungi produce to digest nutrients? Read this paragraph and choose the correct option from the provided answers: The ability of fungi to degrade many large and insoluble molecules is due to their mode of nutrition. As seen earlier, digestion precedes ingestion. Fungi produce a variety of exoenzymes to digest nutrients. The enzymes are either released into the substrate or remain bound to the outside of the fungal cell wall. Large molecules are broken down into small molecules, which are transported into the cell by a system of protein carriers embedded in the cell membrane. Because the movement of small molecules and enzymes is dependent on the presence of water, active growth depends on a relatively high percentage of moisture in the environment. As saprobes, fungi help maintain a sustainable ecosystem for the animals and plants that share the same habitat. In addition to replenishing the environment with nutrients, fungi interact directly with other organisms in beneficial, and sometimes damaging, ways (Figure 24.19). Choices: - pores - amino - sporozoans - exoenzymes A:
exoenzymes

Q: Birds generally practice what kind of relationship, with both parents helping to care for the young? Read this paragraph and choose the correct option from the provided answers: Birds generally are monogamous, and both parents help to care for the young. Choices: - carnivorous - synonomous - homologous - monogamous A:
monogamous

Q: Q: What is responsible for our sense of balance? Read this paragraph and choose the correct option from the provided answers: The ears are also responsible for the sense of balance. Balance is the ability to sense and maintain body position. The semicircular canals inside the ear (see Figure above ) contain fluid that moves when the head changes position. Tiny hairs lining the semicircular canals sense movement of the fluid. In response, they send nerve impulses to the vestibular nerve , which carries the impulses to the brain. The brain interprets the impulses and sends messages to the peripheral nervous system. This system maintains the body's balance by triggering contractions of skeletal muscles as needed. Choices: - our eyes - our limbs - our feet - our ears A:
A: our ears

Question: Q: In drosophila, gradients of morphogens encoded by maternal effect genes determine what? Read this paragraph and choose the correct option from the provided answers: Choices: - cell mass - cells axes - body mass - body axes A:
Answer: body axes

Q: Organisms that live in freshwater environments often possess a contractile vacuole that prevents cells from taking in too much water through what process? Read this paragraph and choose the correct option from the provided answers: Organisms that live in a hypotonic environment such as freshwater, need a way to prevent their cells from taking in too much water by osmosis. A contractile vacuole is a type of vacuole that removes excess water from a cell. Freshwater protists, such as the paramecia shown in Figure below , have a contractile vacuole. The vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole. When the vacuole is full, it pushes the water out of the cell through a pore. Other protists, such as members of the genus Amoeba , have contractile vacuoles that move to the surface of the cell when full and release the water into the environment. Choices: - electrolysis - glycolysis - hemostasis - osmosis A:
**Answer**
osmosis

Q: What does increased temperature do to a substance's kinetic energy? Read this paragraph and choose the correct option from the provided answers: Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature. Choices: - generates - nothing - decreases - increases A:
**Answer**
increases
