Answer the following question given this paragraph: Amphibians play important roles in many ecosystems, especially as middle players in many food chains and food webs. In addition to consuming many worms and insects and other arthropods, and even some small reptiles and mammals and fish, they are prey for turtles and snakes, as well as some fish and birds. Tadpoles keep waterways clean by feeding on algae. Q: What do tadpoles clear out of waterways? Choices: - pollution - oxygen - disease - algae A:
algae
Answer the following question given this paragraph: Transform faults are the site of massive earthquakes. Q: Transform faults are the site of massive what? Choices: - vibrations - storms - tornadoes - earthquakes A:
earthquakes
Q: Answer the following question given this paragraph: The stem of a horsetail is characterized by the presence of joints, or nodes: hence the name Arthrophyta, which means "jointed plant". Leaves and branches come out as whorls from the evenly spaced rings. The needle-shaped leaves do not contribute greatly to photosynthesis, the majority of which takes place in the green stem (Figure 14.15). Q: The stem of a horsetail is characterized by the presence of joints, or nodes: hence the name arthrophyta, which means this? Choices: - solid plant - molted plant - elongated plant - jointed plant A:
A: jointed plant
Question: Answer the following question given this paragraph: Bioterrorism is the intentional release or spread of agents of disease. Q: What is the term for the intentional release or spread of agents of disease? Choices: - diversion - plague - pandemic - bioterrorism A:
Answer: bioterrorism

Answer the following question given this paragraph: The image below shows the way in which a blocked coronary artery can cause a heart attack. The loss of oxygen to the heart muscle cause that part of the tissue to die. Maybe one day, stem cell therapy will allow for the replacement of the dead cells with new cardiac muscle cells. Q: The loss of oxygen to the heart muscle causes that part of the tissue to what? Choices: - beat harder - thrive - beat erratically - die A:
**Answer**
die
Answer the following question given this paragraph: Chapter 26 1 Figure 26.8 B. The diploid zygote forms after the pollen tube has finished forming, so that the male generative nuclei can fuse with the female gametophyte. 3 D 5 C 7 A 9 B 11 C 13 B 15 C 17 D 19 Both pollination and herbivory contributed to diversity, with plants needing to attract some insects and repel others. 21 The trees are adapted to arid weather, and do not lose as much water due to transpiration as non-conifers. 23 The resemblance between cycads and palm trees is only superficial. Cycads are gymnosperms and do not bear flowers or fruit. Cycads produce cones: large, female cones that produce naked seeds, and smaller male cones on separate plants. Palms do not. 25 Using animal pollinators promotes cross-pollination and increases genetic diversity. The odds that the pollen will reach another flower are greatly increased compared with the randomness of wind pollination. Q: When does the diploid zygote form? Choices: - never - before the pollen tube - before the haploid zygote - after the pollen tube A:
after the pollen tube
