This is true.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient exists that allows movement of particles without expending cellular energy.
Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.
Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.
Answer:
The pea plant would produce 1 WW, 2 Wp, and 1 pp. There would be 3 white flowers, and 1 purple.
Explanation:
The DNA undergoes two simplified process I becoming a protein; transcription and translation. Transcription involves the production of a complimentary mRNA strand in the nucleus. The double stranded DNA unzips enzymatically, next DNA polymerase binds to the unzipped DNA and binds complementary nucleotides from the 3' end to the 5' end. This newly formed mRNA strand then moves out of the nucleus where it binds with a ribosome, here complimentary tRNA molecules bind to the mRNA strand thus forming a primary structure protein.
