The function of the structure labeled in the above image

together, forming a structure leg is an organ that is made up of muscle tissue, bone erve tissue, fat tissue, and skin tissue. Other examples of a frog's organs are its eyes, heart, lungs, and stomach. Several organs working together are called an organ system. The digestive system of a frog is an organ system that provides the frog with a way of getting energy from food sources. The digestive system includes the mouth, stomach, small and large intestines, and other organs. Other systems common to most ani- mals are the respiratory system (used for breathing), the circulatory system (used for moving blood), the nervous system (used for transmitting messages to and from the brain), the reproductive system (used for reproduction), and the ex- cretory system (used for the elimination of waste). Vertebrates (animals with backbones) also have a skeletal system that serves as a support structure. Exercise 11: The Structure of Organisms- Directions: Circle T for each statement below that is…

Sketch your favorite animal in the space below and address the following prompts.  Name a feature of your animal that identifies it as an animal instead of another  eukaryote such as a fungus or a plant.   What type of body plan symmetry does your animal display?   What types of tissues are in this animal?  Name a feature that distinguishes this animal from animals in other phyla or groups of  animals.

Which of the following not only increases surface area for nutrient absorption, but also slows down passage of food through the digestive system to allow for a longer time for absorption? the glomerulus the endostyle the amphibian typhlosole the spiral valve the columella O the pneumatic duct

At which end of the pigs body are the organs in the image below found?

at a large Assume that you are the nurse elementary school where children frequently come to you with nosebleeds. Design an experiment to test whether dropping keys down the back of the neck causes nosebleeds to stop. (Assume parents of all children in the school have given permission for their participation in the experiment and you have followed ethical guidelines for research with human subjects. One possible explanation for why keys down the back might actually be effective in stopping a nosebleed is that they are cold, causing blood vessels to constrict. Treatments should be randomly assigned to the children. Describe how you accomplish this. That is, when a child with a nosebleed comes to the nurse's office, how will you know which treatment he or she should get?
