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>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

Answer:
Directional selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype of a genetic trait due to its survival and reproductive advantage to the individuals over another extreme phenotype and the intermediate phenotype. 
In the given example, the thick-leaved plants are better adapted to a drier climate due to reduced water loss. Directional selection favored the plants with thick leaves which in turn produced more progeny. Over the generations, the population evolved into the one having more number of thick-leaved plants.

Answer:The mass of a liquid can be measured using one of these two methods: Method n 1: - Measure the mass of the empty container. - Pour the liquid into the container and measure the new mass. - The mass of liquid is obtained by subtracting the mass of the container to the total mass. hope this makes sense :)
