They form an ionic bond by exchanging one electron
Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
Please make sure that you post a complete question. This is the part missing:
- <span>How might this offset transcription or translation errors?-
The existence of several codons that code for the same amino acid ensure that even when a mistake in the processes of transcribing the sequence from DNA to mRNA or translational errors, there is still a significant chance of correct amino acid being added to the protein.</span>
Answer:
C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
