Why are mycorrhizal fungi superior to plants at acquiring mineral nutrition from the soil? a. hyphae are 100 to 1,000 times larger than plant rootsb. mycelia are able to grow in the direction of food. c. fungi secrete extracellular enzymes that can break down large molecules. d. hyphae have a smaller surface area-to-volume ratio than do the hairs on a plant root.

The correct answer will be option-C

Explanation:

Mycorrhizae are the symbiotic association of the fungi with higher group of plants which could be present inside and form endo relation or could be present outside and form an ectomycorrhizal association.

The mycorrhizal association provide plants benefits as the fungi hyphae are thought to secrete enzymes which help the digestion of the large biomolecules not easily digested by the plants thus providing an extra amount of nutrients to the plants and thus plants shows growth.

Thus, Option-C is the correct answer.

events in order:

1.       vishnu schist

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
