A strand of mRNA is the compliment to the coding strand of DNA. It kind of has the opposite information from DNA (if a DNA strand is TCCGATC the compliment mRNA would be AGGCTAG). This way, it is able to retain the information when travelling to the ribosome for translation (aka, turning the DNA information in proteins)
One year. It takes 365 days for Earth to orbit the sun.
Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Chordates (phylum Chordata) are animals which are either vertebrates or one of several closely related invertebrates. They are united by having, for at least some period of their life cycle, a notochord, a HOLLOW DORSAL NERVE CORD
