Question

QUESTION 14 The experimental setup shown in the figure was designed to test which of the following? Dictyostelium cells Light source Nutrient free agar Single-celled amoeba stage Slug Bacteria Soil O a. competition between slime mold slugs and amoebas Ob. the consumption of amoebas by slime mold slugs Oc. the reproductive ability of slime mold slugs and amoebas O d. the economy of scale of slime mold slugs and amoebas regarding efficiency of travel

Answer 1

Answer:-

The correct potion is (d) i.e the economy of scale of slime mould slugs and amoebas regarding efficiency of travel. The above experimental setup is performed by the Joan Strassman. Through the experiment, he concluded that the slug moves faster than the amoeba and thus revealed a selective advantage. Slugs are formed by the slime mould (Dictyoatelium cells) through the chemical signals which results in the aggregates and these aggregates has many advantages like they are involved in the formation of slime sheath in order to protect slug. Rate of reproduction of slug is higher and it is more effective due to economy scale.

Hope the above answer comes up to your expectation. Please do come up with your feedback.
