Question

thats life
directions write the letter of the phrase from the box that completes each sentence.
a the offspring are unique
b frogs came from mud
c living things come from other living things
d only humans can produce humans
e a population is more likely to survive change

1. because people believed that living things came from nonliving things, they thought that
2. because of redis experiments, scientist began to learn that
3. because each organism has its own unique dna,
4. because reproduction in most animals involves two parents,
5. because of diversity,

directions circle the word or phrase that goes with each meaning clue.

1. living from nonliving spontaneous generation or reproduction
2. range of differences diversity or population
3. a characteristic survival or trait
4. a chemical in a cell dna or bacteria
5. traits that allow survival advantages or adaptations

directions tell how the items in each pair are related

1. dna, reproduction
2. eggs, frogs
3. adaptations, resistance to disease
4. traits, dna
5. spontaneous generation, rotten meat

Explanation:

1. The belief in living things coming from non - living things led to the idea that frogs came from mud. Redi's experiments showed that living things come from other living things.
2. Each organism has unique DNA, so the offspring are unique.
3. With two - parent reproduction in most animals, the offspring are unique.
4. Diversity helps a population be more likely to survive change.
5. Diversity makes a population more likely to survive.
6. Living from non - living is spontaneous generation.
7. Range of differences is diversity.
8. A characteristic is a trait.
9. A chemical in a cell is DNA.
10. Traits that allow survival are adaptations.
11. DNA contains the genetic information for reproduction.
12. Eggs develop into frogs.
13. Adaptations can include resistance to disease.
14. Traits are determined by DNA.
15. Spontaneous generation was once thought to occur with rotten meat (e.g., maggots appearing).
