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.
Answer:
An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
because it is a new virus that us humans have not experienced and we are still learning about it
