d. i, ii, and iii

1. what do budding, binary fission, and spore formation have in common?

a. they require two parent cells.

d. they are all forms of sexual reproduction.

1. which of the following methods do bacteria that cause tooth decay use to reproduce?

a. budding
c. spore formation
b. binary fission
d. vegetative propagation

Explanation:

• Question 7: Budding, binary fission, and spore formation are all asexual reproduction methods. In asexual reproduction, the offspring (daughter cells) are genetically identical to the parent cell as there is no genetic recombination from two parents.
• Question 8: Budding (e.g., yeast), binary fission (e.g., bacteria), and spore formation (e.g., fungi) are all asexual reproduction methods. Asexual reproduction requires only one parent cell. Sexual reproduction requires two parent cells. Budding can produce multiple daughter cells over time (as the bud detaches and the process repeats), binary fission produces two daughter cells from one parent cell, and spore - forming organisms can produce many spores (daughter cells equivalent in this context).
• Question 9: Bacteria reproduce by binary fission. In binary fission, a single bacterial cell divides into two daughter cells. Budding is common in yeast (a fungus), spore formation is common in fungi and some plants, and vegetative propagation is a form of asexual reproduction in plants (e.g., through roots, stems, or leaves).

Answer:

1. D. I, II, and III
2. B. They require only one parent cell.
3. B. binary fission
