Even after seemingly complete endoscopic resection recurrence of neoplasia is frequent and independent of additional thermal therapy.
Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.
How carrier protein facilitate the diffusion?
When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.
Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.
Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.

Answer:
1.) The two gametes found in humans are the sperm and the ova.
2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
3.) Because the alleles that the mother and the father carry are mixed together in the offspring.
4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
Please this is all I can answer
Answer: Graphs are diagrammatic representation of relationships.
Explanation: Have a great day!!!! Hope this helps.
Modelling refers to using a diagrammatic representation to present a particular event or biological activity.
The two maps shown are very good for representing/modelling mitosis.
Advantages
- They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
- The M phase was also clearly explained in the first diagram.
Disadvantages
- The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
- The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.
