SHORT ANSWER

1. What are the 8 characteristics of Living Things?

1. What are the 8 characteristics of Living Things?

1) are based on a universal genetic code2) grow and develop3) respond to their environment4) are made up of cells5) taken as a group, living things evolve6) obtain and use materials and energy7) maintain a stable internal environment8) reproduce

2. What is the relationship between photosynthesis and cellular respiration?

2. What is the relationship between photosynthesis and cellular respiration?

The products of one reaction become the reactants of the other. In other words, each reaction makes what the other reactions needs.

3. What is the difference between growth and development? Give examples.

3. What is the difference between growth and development? Give examples.

Growth means getting larger; development means changing features.

examples: butterfly life cycle; puberty

4. Give an example of an external stimulus and response.

4. Give an example of an external stimulus and response.

5. What is natural selection? Include mutations and adaptation in your explanation!

5. What is natural selection? Include mutations and adaptation in your explanation!

1) Changes in the DNA of an organism may happen by mutation.

2) If the trait benefits the organism the organism is more ‘fit’ for survival and reproduction of another generation of offspring.

3) The new trait may be passed on to the next generation of offspring.

4) Eventually, if successful then this trait will be present in a greater percentage of the population.

5) The group of organisms can be said to have adapted to their environment.

6) When a large number of changes happen over time, a new species may form and the organism has evolved.

GOOD LUCK!
