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 Uropods. 

 

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 .

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

Therefore option D is the right option

Anhidrosis is the inability to sweat normally. If the human body cannot sweat properly, it cannot cool itself, which is potentia

KiRa [710]

a feedback mechanism that maintains homeostasis

Explanation:

Anhidorosis mostly directly interferes with a feedback mechanism that interferes directly with a feedback mechanism that maintains homeostasis.

Since anhidorosis is the inability to properly or normally sweat, it affects the process of homeostasis.

Homeostasis is an important characteristics of life.

It is the ability of organisms to maintain and sustain a balance environment within and outside of them.

Sweating is one such process by which the body carries out homeostasis. On a hot day, the body produces sweat which evaporates and release latent heat to cool the body. This inability affects the intricate balance between the environment and the body.
