How do the circulatory system and immune system work together to respond to an injury?
Which two body systems must directly interact for vertebrate organisms to exchange gases?
Plant roots have extensions called rood hairs. These roots hairs are important in the homeostasis of a plant. Which statement best explains the importance of the root hairs to the stems and leaves of the plant?
A corn plant produces both male and female flowers. The male flowers form the tassel and the female flower forms the ear of the corn. The silks that emerge from the ear are the stigma of the female flowr. Each silk leads to an ovule that can become a corn seed. Which of these must happen for corn seeds to develop on the ear?
A student conducted an investigation to study phototropism in grasses. The only difference 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?
The human body is composed of organ systems. Which list represents a system organized from leas to most complex?
The diagrams show some of the levels of biological organization. In what order are the levels in the diagrams?
Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls, such as cellulose and lignin. Which statement explains why these fungi are an important part of the biogeochemical cycle?
A student researching bacteria concluded a report with the claim on the box. Which statement correctly addresses the validity of the claim?
A small town in the piney woods of East Texas has a soccer field composed of native grasses. The soccer field is mowed once a week. What effect does continual mowing have on the ecology of the field?
Enchanted Rock State Natural Area is located in Central Texas. Enchanted Rock is a dome of granite. The area contains four easily identifiable communities. The table describes the characteristics of each type of community in the area. A student studying primary succession should focus on which of these communities?
