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.

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents

explanation:

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
