3. Offspring inherit genes from both parents. Most genes in most species exist in an array of possible forms known as

1. genomes
2. traits
3. alleles
4. chromosomes

4. The five-kingdom classification system used by scientists includes:

1. Animalia, Plantae, Fungi, Virus, Bacteria
2. Animalia, Plantae, Fungi, Monera, Carnivore
3. Animalia, Plantae, Fungi, Protista, Bacteria

5. There are different forms of reproduction in organisms. Asexual reproduction involves only one parent. A hydra reproduces asexually when it produces a smaller version of itself by

1. binary fission
2. spore production
3. budding
4. vegetative reproduction

6. When a plant cutting produces a new individual, it does so without the formation of a seed. This type of asexual reproduction is called

1. binary fission
2. spore production
3. budding
4. vegetative reproduction

7. Suckers (which are miniature identical forms of the parent plant) can be formed in the roots of poplar trees. Each of these suckers can produce trees identical to the parenttree. This form of asexual reproduction is called

1. binary fission
2. spore production
3. budding
4. vegetative reproduction

8. When populations of different species live together within the same area, these populations form what is known as a

1. congregation
2. community
3. collection
4. ecosystem

9. A symbiotic relationship where one species benefits and the other species is harmed is called

1. mutualism
2. parasitism
3. commensalism
4. colonialism

10. All living cells contain DNA. In the cells of plants and mammals, DNA is located in the

1. nucleus
2. vacuoles
3. cytoplasm
4. mitochondria

12. When a female cell (egg) is penetrated by a male cell (sperm) this occurs

1. cleavage
2. pollination
3. fertilization
4. specialization

13. Cross-fertilization occurs when a pollen grain

1. from one plant fertilizes the plant it belongs to
2. is not able to pollinate another plant
3. from one plant fertilizes a different plant
4. is carried by the wind, water or animal to another plant

14. To better understand variation; scientists explore the characteristics, which are passed on from generation to generation within a species. Those characteristics that are passed on from generation to generation are

1. inherited
2. non-inherited
3. genetic
4. non-genetic

15. This type of characteristic, eye color, is considered to be
