(1) growth and maintenance (3) asexual reproduction

from the parent cells?

(2) sexual reproduction

(4) production of sex cells

(1) yeast cells splitting into new cells

(2) bacteria cells dividing into new cells

2. A new yeast cell is sometimes produced from a single

(3) skin cells dividing to produce more skin cells

parent by a process called budding. The process of budding

(4) sperm and egg cells uniting to produce fertilized egg cells

is best described as

(1) sexual reproduction, with genetically identical offspring

13. In animal skin tissue, cell division is responsible for

(2) sexual reproduction, with genetically different offspring

(1) growth and repair

(3) obtaining energy

(3) asexual reproduction, with genetically identical offspring

(2) sexual reproduction

(4) production of sex cells

(4) asexual reproduction, with genetically different offspring

14. Which process is represented by the diagram below?

3. When do organs begin to develop in humans?

(1) in the sperm cell before fertilization

(1) asexual reproduction

(2) before fertilization and after birth

(2) photosynthesis

(3) in the egg cell after fertilization

(3) ecological succession

(4) after fertilization and before birth

(4) metamorphosis

4. Which process gives rise to a variety of traits within

a species?

(1) sexual reproduction

(3) cellular respiration

(2) dynamic equilibrium

(4) internal regulation

15. Which process is illustrated in the diagram below?

5. In sexual reproduction, what fraction of genes does each

parent contribute to the offspring?

(1) ¼

(2) 1/3

(3) ½

(4) ¾

6. A male chimpanzee has 48 chromosomes in each of his

regular body cells. How many chromosomes would be

(1) natural selection

(3) metamorphosis

found in each of his sperm cells?

(2) mutation

(4) photosynthesis

(1) 96

(2) 48

(3) 24

(4) 12

16. Which process is shown in the diagram below?

7. Asexually produced offspring are genetically

(1) identical to the parent

(2) different from the parent

(3) different from each other

(4) formed by two parents

(1) metamorphosis (2) regulation (3) fertilization (4) respiration

8. Compared to the amount of hereditary information

in a human body cell, how much hereditary

17. Which process is shown in the diagram below?

information is contained in a human sex cell?

(1) one-quarter the amount (3) the same amount

(1) evolution

(2) one-half the amount

(4) twice the amount

(2) migration

(3) photosynthesis

9. A plant produces tiny plants around the edges of

(4) metamorphosis

its leaves. When these tiny plants fall to the ground,

they take root and become new plants.

This process is an example of

(1) sexual reproduction

(3) evolution

18. The diagram below shows information about the reproduction

(2) asexual reproduction

(4) extinction

and development of a rabbit.

Which letter in the diagram represents

10. Each body cell of a goldfish contains 94

fertilization?

11. What advantage does a species that reproduces

(4) D

sexually have over a species that reproduces asexually?

(1) There is greater variation among the offspring.

(2) The offspring are identical to the parents.

(3) Only one parent is necessary for reproduction.

(4) No sex cells are needed for reproduction.
