Protists are very diverse, and many different classification schemes have been used to define relationships between the protists
andrey2020 [161]

Answer:

D. heterotrophic by ingestion, pseudopods

Explanation:

Protists are generally classified  as all eukaryotic organisms that are not plants, animals or fungi. Example is amoeba, paramecium etc.They may be unicellular or multi cellular in nature.Most exist in colonies.

Their mode of nutrition can be photosynthetic or hetrotrophic. Hetrotrophic  protists   can be divided into  phagotrophs and osmotrops/saprotrophs. The phagotrophs  makes use of the cell body to engulf the food materials as  in amoeba ,carry out extracellular digestion before swallowing it.

Osmotrops absorbed dissolved food from surrounding liquid environments directly. (Some photosynthetic protists can also be heterotrophic.

Amoeboid movement is the mode of locomotion of protists and some  other eukaryotes. It involved the protrusion of cytoplasm, which exert pressure on the cell membrane to form pseudopodia and  the posterioly  evolved  <u>Uropods. </u>

<u />

<u>  </u>

<u>Sol-gel theory has been proposed to expalin this movements, The ectopalsm of amoeba is gelly-like , while the endiplams is less viscpus   and said to be sol. The interchange of the cytoplasmic fluis between the endo-and ecto plasm gives the SOL-GEL propulsion of the protopalms for the amoebic moveemnts .</u>

<u />

<u>The false feet(psuedopodium) drags the amoeba  along in the direction of the flow of the cytoplasm.</u>

Therefore option D is  the right option

In what way is DNA like a book?
Alekssandra [29.7K]
<span>A book contains letters, just like the DNA. It's how the letters are arranged-into words in a book- that makes them mean anything. The same is true of DNA bases. It is how they are arranged that makes them significant.</span>
