In simple terms, there are 4 categories of protists in basic biology characterized by their type of locomotion.
Locomotion by pseudopods or "false feet" is characteristic of ameobas (i.e. <em>Entamoeba histolytica</em>). Locomotion by papillary projections from the cell membrane called "cilia" is characteristic of <em>Paramecium </em>species. Locomotion by whip-like structures that propel the organism called "flagella" is characteristic of <em>Euglena </em>species.

Lastly, protists that do not have locomotive organelles are exemplified by <em>Plasmodium </em>species, the etiologic agent of malaria.

Answer:
d. A smaller body size
Explanation:
The smaller a body size is the larger the body surface area is. Larger body surface area would allow for increase in lost of more excess heat to the environment.
Therefore, hypothetically, one of the obvious adaptation that would be evolved by the rat population that was moved from their previous cold northern tundra climate to a desert environment is a smaller body size. This would enable them in cooling off and preventing over-heating.
Answer:
Blood plasma is a 'yellowish liquid' component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.
The answer is ‘arteries are less flexible’. This is why the older you get the more predisposed you
are to cardiovascular diseases such as high blood
pressure. However, regular
exercise may delay this development. The barometers in the blood vessels also
become less sensitive hence these vessels become less responsive to blood
pressure changes.
