BYU Exam 1 Questions and Answers 100% Pass What is means to be a homo sapien- characteristics that define us as a species - Correct Answer ️️ -human beings are living organisms. Characteristics: 1. Complex language is the main way humans are identified from other matured species such as apes. We are the only organism on earth that has the compacity for complex language. 2.. Humans have one the largest brains out of any other organism. Not only that, we have the capability of expanding our knowledge and contacting areas of our brain that other organisms cannot. 3. Opposable thumbs: although apes have five fingers, they are unable to use their thumbs for motor skills like humans. This example is displayed in the picture of the textbook in which an ape is unable to grasp a pencil in a similar manner as a human. 4. Bipedalism: humans are the only species that walks on two legs and has arms to carry and use for function. 5. Some might argue that an advantage of the human species is that we can reproduce numerously - however other species can as well. Our advantage is that environmentalism does not effect our species as much as others; therefore we can continue to produce without threat of extinction. How science is both a body of knowledge and a process - Correct Answer ️️ - The scientific method - Correct Answer ️️ -1. formulate a hypothesis 2. observe and generalize 3. make a testable prediction 4. experiment 5. modify as needed and repeat Characteristics of living things - Correct Answer ️️ -1.

The function of each, and examples. - Correct Answer ️️ -1. Lipids - example: fat - subunit: steroids - functions: store energy 2. Carbohydrates - example: Polyssaccharide - subunit monosacchides - function: used for energy and structural support 3. Proteins - example: enzymes - subunit: amino acids - functions: structural support, muscle contraction, cell membrane to transmit information 4. Nucleic acids - example: DNA and RNA - subunit: nucleotides - function: store genetic material The difference between DNA and RNA. The role each plays within the body - Corr
