8. The wildflower field would likely suffer as a result of reduced pollination. With fewer bees to transfer pollen, there would be fewer plants producing seeds and new plants. This could have long-term effects on the ecosystem, as the wildflowers play an important role in providing food and habitat for many other organisms.
9. Anther, Filament, Stamen
10. By feeding on the fruit and dispersing the plant's seeds to new locations, or by serving as a pollinator for the plant's flowers.
11. The flower is the part of the plant that attracts pollinators and facilitates fertilization, leading to the production of seeds and the continuation of the species.
12. Ants use grouping for protection of the young, while elephants use grouping for cooperation.

1. The first blank is "Systemic" circulation, and the second blank is "Pulmonary" circulation. Systemic circulation refers to the movement of blood from the heart to the rest of the body and back to the heart. Pulmonary circulation refers to the movement of blood between the heart and the lungs.
2. Based on stimuli to your thermoreceptors, you could make the observation of feeling hot or cold. Thermoreceptors are sensory receptors that are sensitive to changes in temperature and provide information about the body's thermal environment.
3. The kidneys are part of the excretory system. Their major job is to cleanse the blood by filtering out waste products and excess fluids, and transform them into urine.
4. When the small child accidentally puts their hand on a hot stove top, the stimulus of the hot stove is perceived by the brain through the activation of pain receptors in the skin. These receptors send electrical signals to the brain through the nervous system, alerting the brain to the possibility of tissue damage and causing the child to quickly withdraw their hand.

- Cells
- Tissues
- Organs
- Organ systems
- Organisms
9. Food is broken down in the mouth and stomach.
10. Blood vessels called capillaries carry nutrients from food and oxygen to the rest of the cells in the body. Capillaries are the smallest blood vessels and facilitate the exchange of gases, nutrients, and waste products between the blood and surrounding cells.
11. Sclera is not part of a nerve cell. Sclera refers to the white outer layer of the eye, while nerve cells, or neurons, consist of a cell body, dendrites, and an axon.
12. True. Bones provide shape and structure to the human body, as well as support for muscles and protection for organs.
13. Circulation decreases in a bird when it becomes too warm. This example shows an organism that cannot reach homeostasis through internal changes.
