Which best describes the digestive system of arthropods? a incomplete, two openings b complete, one opening c two-way, one opening d one-way, two openings

The correct answer is: d, one-way, two openings.

The digestive system of arthropods begins with the opening in the mouth (where food enters the system) and it finishes with the anus (where food leaves the system). Because of that, it’s one-way.

Each arthropod has a different digestive system according to their method of feeding and body structure, but each of them has mouth opening and anus. Because of that, it’s two openings.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
