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.
Answer:
a. Lipid emuslification
Explanation:
Fats are organic compounds whose main function is to provide energy for the body to help transport and absorb fat soluble vitamins and to incorporate essential fatty acids that the body does not produce on its own. Fat digestion begins when the chyme passes from the stomach to the duodenum, where the bile assists in the digestion of fats and other lipids. When the chyme is in the duodenum, a hormone stimulates contraction of the gallbladder walls and releases bile through the common bile duct.
The correct answer is: sodium gradient
It is very important for glucose to be transported into proximal tubule cells (reabsorbed) because that is the way to prevent it from disappearing from the body through the urine.
Glucose is co-transported with sodium ions into the proximal tubule via the SGLT2 cotransporter. This cotransporter is an example of secondary transport because it uses the energy from downhill sodium ion gradient created by the ATPase pump to transport glucose.
