Planarias are flat worms that live freely in freshwater and sometimes in teh logs, soil, plants, or other dump or humid areas. They are from the class of Turbellarians. They have a very good ability in regeneration. They are acoelomerate which means that their body is very solid without any hollows. 

They excrete unwanted objects from their body using their excretory system which is consists of series of tubes with length similar to their body length. The flame cells remove excess water through the use of the cilia and pass them to the ducts. At the end of the duct, there exist pores called the nephridiapores.

What is the driving force for the filtration of blood by the renal corpuscle?
Ipatiy [6.2K]

Answer:

Higher pressure in glomerular capillaries than in the surrounding Bowman's capsule.

Explanation:

The renal corpuscle is composed of the capillary glomerulus and the Bowman's capsule that covers it, there is a space inside the capsule, Bowman's space, where the filtered liquid from the glomerulus passes. The glomerular pressure must be higher than in the surrounding Bowman's capsule, so in that way it forces the filtration and tends to expel fluid from the glomeruli, allowing the passage of water, small molecules of solute and ions.

A caterpillar has an exoskeleton and feeds on many leaves before it makes a cocoon and becomes a butterfly. Which type of organi
Nutka1998 [239]

Answer:

heterotroph and an invertebrate

Explanation:

Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.

In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.
