Protists that ingest visible particles of food are called
a. phototrophs
b. phagotrophs
c. osmotrophs
d. saprozoic feeders

The correct answer will be option-B.

Explanation:

Protist is the group of the organism which is eukaryotes but nither considered true animals, fungi and plants.  

Their mode of nutrition is either osmotrophic or phagotrophic. The phagotrophic feeds on the macroparticles like organic particles by surrounding the particle and swallowing it through phagocytosis. The ingested particle gets digested inside the body pf the organism. The phagotrophic organisms are like amoeba and dinoflagellates.

Thus, Option-B is the correct answer.

you keep track of variables in your data table.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
