Answer:
For functioning of heart, circulatory and execratory systems are required.
Explanation:
It requires at least two body systems to perform the function because the functions does not be completed solely, it requires coordination among systems which help them to fulfill their task. For example, the function of the heart requires circulatory system and execratory system for the pumping of blood throughout the body. it is an involuntary action which is not control by nervous system.
Answer:
It performs all function ion for the organism. Mostly likely a prokaryote.
The correct option is this: BOTH MOVE MATERIALS DOWN A CONCENTRATION GRADIENT.
Active transport is a type of transport in the living cells in which energy is needed to move materials across a semi permeable membrane against a concentration gradient. Passive transport on the other hand is a type of transportation in cells, in which energy is not needed to move the materials across a biological membrane but the movement of the materials is against a concentration gradient.
Answer: C
Explanation:
A is incorrect because prokaryotic cells have their DNA floating in the cytoplasm
B is incorrect because Eukaryotic cells are what is found in humans and we are not single-celled organisms
C is correct because Eukaryotic cells contain their DNA in a nucleus
and D is incorrect because prokaryotic cells are not found in all plants, however, plant cells might have adopted come prokaryotic bacteria throughout their evolution but that's unrelated
