Which statement best compares pseudopods in sarcodina and flagella in dinoflagellates? a.) pseudopods are whip-like structures, while flagella are flat structures involved in photosynthesis. b.) both pseudopods and flagella are used for movement, but only pseudopods are used to engulf food. c.) pseudopods are permanent projections from a cell, while flagella can be retracted into the cell. d.) both pseudopods and flagella are used for reproduction, but only flagella are used for movement.

The answer is; B

Pseudopodia  are projections of the cell of the organism that dynamically change in shape and size while flagella is an appendage structure that rotates and flips to move the organisms. Pseudopodia are temporary while the flagella is a permanent structure. Organisms that bear pseudopodia are majorly protozoans while those that are mainly bacteria. The process by which pseudopodia engulf food is called endocytosis.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
