SHORT ANSWER
1. What are the 8 characteristics of Living Things?
1. What are the 8 characteristics of Living Things?
1)
2)
3)
4)
5)
6)
7)
8)
are based on a universal genetic code
grow and develop
respond to their environment
are made up of cells
taken as a group, living things evolve
obtain and use materials and energy
maintain a stable internal environment
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!
