Pond water contains a variety of plant and animal life. While some are visible to the plain eye, others require a microscope to observe them. For example, there's bacteria, protozoa, hydras, algae, and arthropods. You will have the opportunity to see a number of microorganisms from both the plant and animal kingdom.

Circulating throughout the body, adh arrives at the nephrons of the kidneys, Nephrons are the basic microscopic functioning unit of the kidneys. Our kidneys consist of millions of nephrons.
ADH stands for anti-diuretic hormone and it is also known as vasopressin and it is secreted by the pituitary gland and it helps the kidney to maintain the water in the body.

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

Part A: Describe the general composition of a protein molecule. Be sure to include the elements that make up a protein

jarptica [38.1K]

A protein is a polymer of amino acids. When amino acids are joined by dehydration synthesis (a process that removes water to form a chemical bond), they form peptide bonds. There are three main components of an amino acid, the amino group, the side chain, and the carboxylic acid group.
