A labeled model of an amoeba is shown above. These are heterotrophic, single celled protists. They have unique cellular structur
es called pseudopodia that facilitate movement and food acquisition. What type of cell transport likely accounts for the formation of the food vacuole within the amoeba? A) phagocytosis
B) active transport
C) simple diffusion
D) facilitated diffusion
An amoeba usually gets its nutrients from engulfing large food particles by the process of phagocytosis.
As an amoeba approaches the desired food particle, it <u>extends it pseudopods</u> around it, eventually <em>surrounding the food </em>and internalizing it.
The food then becomes enclosed by the pseudopodia, creating a <u>food vacuole</u>.
Digestive enzymes, such as <u>lysosomes</u>, will <u>fuse with the food vacuole</u> and start breaking down the food. The nutrients will then be diffused throughout the cytoplasm.
Preventive maintenance is where measure are taken beforehand so that the chances of breakdown are minimised resulting in increased efficiency of machines. It is the maintenance that is regularly performed on any equipment to lessen the likelihood of it failing.
The peripheral nervous system has - Somatic nervous system and Autonomic nervous system.
These systems control our body action by this controls all the types of muscles.
Explanation:
Somatic nervous system have - Cranial nerves and Spinal nerves
Autonomic nervous system have - Sympathetic and Parasympathetic system.
The somatic nervous system controls our voluntary and involuntary actions by cranial and spinal nerves and controls all three types of muscles such as cardiac, smooth and skeletal.
The autonomic nervous system controls the involuntary actions of our internal organs.
The sympathetic and parasympathetic system relates to all types of muscle.
The sympathetic and parasympathetic system accelerates and decelerates the heart beat respectively, by this controls the cardiac muscle.
The sympathetic and parasympathetic system stimulates and relaxes our internal organs respectively, by this controls the smooth muscles.
The sympathetic and parasympathetic system prepares our body as a whole for a action and also relaxes our whole body respectively, by this controls the skeletal muscles.
