Q: Answer the following question given this paragraph: 34.1 | Digestive Systems By the end of this section, you will be able to: Explain the processes of digestion and absorption Compare and contrast different types of digestive systems Explain the specialized functions of the organs involved in processing food in the body Describe the ways in which organs work together to digest food and absorb nutrients Animals obtain their nutrition from the consumption of other organisms. Depending on their diet, animals can be classified into the following categories: plant eaters (herbivores), meat eaters (carnivores), and those that eat both plants and animals (omnivores). The nutrients and macromolecules present in food are not immediately accessible to the cells. There are a number of processes that modify food within the animal body in order to make the nutrients and organic molecules accessible for cellular function. As animals evolved in complexity of form and function, their digestive systems have also evolved to accommodate their various dietary needs. Q: Animals that have feeding patterns that are somewhere between that of herbivores and carnivores can be called what? A: | OPTIONS:
- insectivores
- nematodes
- megavores
- omnivores
A: omnivores

Q: Answer the following question given this paragraph: When electrons are removed from an atom, that process requires energy to pull the electron away from the nucleus. Addition of an electron releases energy from the process. Q: What is required when electrons are removed from an atom, and released from the process when an electron is added? A: | OPTIONS:
- nuclear
- proton
- fuel
- energy
A: energy

Q: Answer the following question given this paragraph: The cell is the smallest unit of structure and function of all living organisms. A cell is also the smallest unit of life, with single-celled organisms present on this planet for over 3.5 billion years. Single-celled ( unicellular ) organisms like bacteria are obviously composed of just one cell, whereas multicellular organisms can be composed of trillions of cells. Multicellular organisms include protists (though single-celled protists also exist), fungi, plants and animals. Most plant and animal cells are between 1 and 100 m and therefore can only be observed under the microscope. Q: What is the smallest unit of structure and function of all living organisms? A: | OPTIONS:
- chromosome
- organelle
- organ
- the cell
A: the cell
