How can protists exhibit both animal-like and plant-like characteristics?
Kay [80]

A heterotrophic and chlorophyll protist

Food is ingested by protists in three forms. We produce, eat and digest their own organic molecules. Meat ingestion or english bacteria ingests protists. The cell wall and cell membrane are stretched to create an alimentary vacuolum around the foodstuff. Enzymes extract the food inside the food vacuole. At the other side, absorbent protists consume food molecules through their cell membrane by diffusion. In decomposition, absorbent protists play a crucial role. They are assumed to be essential decomponents. Light energy is used to make your own food by big farmers including photosynthetic protists.

Which linkages would you expect to find at a branch point in glycogen or amylopectin?
shusha [124]

Answer:

α-1,6-glycosidic linkage.

Explanation:

The carbohydrates are the polymers made of the sugars and bonded together through the glycosisdic bonds. The monosaccharides are the simplest unit of the carbohydrates.

The glycogen and amylopectin share similar structural features. Both have α-1,4-glycosidic linkage in their linear structure. The branching has been introduced in the glycogen and amylopectin structure through the α-1,6-glycosidic linkage.

Thus, the answer is α-1,6-glycosidic linkage.
