STAAR Review Day 7

10B The internal transport of water and minerals in plants requires that two systems work together. Which diagram correctly describes how the two systems accomplish this?

10B Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots.How are gibberellins able to affect other parts of the plant?

10B Several structures work together to allow flowering plants to reproduce. The diagram shows a typical flower.

Which table correctly identifies the function of each structure or group of structures in the reproduction of the plant?

10B: A student conducted an investigation to study phototropism in grasses. The only different between the control group and the experimental group was light conditions. The control group was provided full light, while the experimental group was shaded on one side. The diagrams show the average heights and positions of blades of grass in the investigation. Which statement best explains why the grass tips of the experimental group bent toward the light?

9B: Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?

9B Diatoms are one of the most common types of phytoplankton in marine habitats. Like plants, diatoms contain chlorophyll and produce glucose from which of the following?

10A Coracias garrulus is a blue bird with an orange-brown back. The offspring of this bird have an effective defense mechanism. The young birds vomit and cover themselves in a foul-smelling orange liquid when they sense a threat by predators. Which two systems alert the young bird to the danger and help produce the vomit it uses as a defense?

10A: During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus. The vigorous contraction of the uterine smooth muscle helps push the baby through the birth canal so that delivery can occur. This process involves the interaction of which organ systems?

10C The diagrams show some of the levels of biological organization. In what order are the levels in the diagrams?

10C A science class is planning a field trip to a local farm that has a large pond. Which of the following lists the order of biological organization from smallest to largest that the students can expect to find at the pond?
