Question

the life cycle of a slime mold is shown here. it has both sexual and asexual reproductive abilities. the majority of the life cycle is spent as haploid. a student observes a population of slime molds cultured from a forest ecosystem. the student notes that there are many slime molds in the diploid (2n) form. what statement best describes the conclusions that the student can draw? a slime molds were unable to form a fruiting body, which resulted in an increase in diploid forms. b slime molds were able to reproduce more quickly using sexual reproduction, which resulted in many diploid forms. c slime molds lacked an essential nutrient in the environment to allow for reproduction, which resulted in many diploid forms. d slime molds were able to tolerate changing conditions in the forest with greater genetic diversity, which resulted in many diploid forms.

Explanation:

Slime molds produce diploid (2n) forms via sexual reproduction (fusion of haploid gametes). If many diploid forms are present, it implies active sexual reproduction. Option B links sexual reproduction (which generates diploids) to the observed many diploid forms, making it the best conclusion.

Answer:

B. Slime molds were able to reproduce more quickly using sexual reproduction, which resulted in many diploid forms.
