2

Both store energy used by the organism

3

Both support the structure of the organism

4

Both store information for the organism

Multiple Choice

6G Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?

1

Mitosis

2

Fertilization

3

Meosis

4

Binary fission

13

Multiple Choice

6G: During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material:

1

increases the genetic variation

2

reduces the diploid number to the haploid number

3

increases the haploid number to the diploid number

4

reduces the probability of mutations

6G: In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan's investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs. Which statement about the event represented in the diagram is valid?

1

The event represents RNA translation into smooth endoplasmic reticulum

2

The event takes place in bacteria cells

3

The event produces genetically identical daughter cells

4

The event provides genetic diversity in eukaryotic cells
