UNIT 1: Lesson 1 Key Questions: 1. Magnesium consists of 12 electrons; 2 + indicates a loss of 2 electrons; therefore‚ it now has 10 electrons. 2. The isotope would not be useful for dating bones that are over a million years old because carbon-14 decay at a constant rate‚ with a half-life of 5730 years. Therefore‚ after 40‚ 000 years‚ les than 1% of the carbon-14 is left in the tissue. As a result‚ there is not enough of the isotope in the tissues to determine the age of the bones. 3. The four

Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there
