How does an amoeba compare with a red blood cell?

A. They both have pseuopods
B. They are both organisms
C. An ameoba is responsible for all functions, and a red blood cell is responsible for some functions
D. An ameoba is responsible for one function, and a red blood cell is responsible for all functions

C. An amoeba is responsible for all functions, and a red blood cell is responsible for some functions.

An amoeba is a single-celled organism that carries out all the functions necessary for its survival, including movement, feeding, reproduction, and responding to stimuli. On the other hand, a red blood cell, while also a single cell, has a specialized function of transporting oxygen to the body's tissues and removing carbon dioxide.

Which statement is correct about an euglena and a white blood cell?

A. An euglena can survive on its own, but a white blood cell cannot.
B. A white blood cell can survive on its own, but an euglena cannot
C. Neither an euglena or a white blood cell can survive on their own
D. Both an euglena and a white blood cell can survive on their own

A. An Euglena can survive on its own, but a white blood cell cannot.

Euglena is a single-celled organism that is capable of photosynthesis and can produce its own food. It has the ability to move and reproduce independently. In contrast, white blood cells are part of the immune system and are specialized cells that cannot survive on their own outside the body. They rely on other bodily systems for support and survival.

A. They both have pseudopods. This statement is correct. Both amoebas and red blood cells have pseudopods, which are temporary projections of the cell membrane used for movement.

B. They are both organisms. This statement is partially correct. Although both amoebas and red blood cells are part of living organisms, amoebas are unicellular organisms, whereas red blood cells are specialized cells within a multicellular organism.

C. An amoeba is responsible for all functions, and a red blood cell is responsible for some functions. This statement is incorrect. Amoebas are responsible for various functions such as locomotion, feeding, and reproduction, while red blood cells have a specific function of carrying oxygen to different parts of the body.

D. An amoeba is responsible for one function, and a red blood cell is responsible for all functions. This statement is incorrect. Amoebas are capable of performing multiple functions required for survival, while red blood cells have a specialized function of transporting oxygen and carbon dioxide.
