D- both involve moving substances across a membrane
Reasoning:
-Active transport moves against the concentration gradient ( low to high)
-Passive transport moves higher to lower concentration
Answer:
they control small specific functions in the cell
Explanation:
genes are very crucial in every organisms since they determine the tiniest composition of the cell,evolving from the parent organism.
Answer: the insertion of a nucleotide into DNA
Explanation:
Answer:
A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.
