<span>Exons from the same gene (like you said above) could be spliced in different ways to make different 'mRNAs'.</span>
There is also evidence that they may not have the same capacity to multiply as embryonic stem cells do. Hope this helps :)
Answer:
Simple Diffusion.
Explanation:
The plasma membrane is known as the selectively permeable membrane as they allow the movements of some selected particles only. The movement are facilitated diffusion, active transport and passive transport.
Water molecules are polar in nature. They can pass through the plasma membrane from its region of the higher concentration towards its region of the lower concentration. They move directly through the simple diffusion and does not require any protein or energy molecule to pass through them.
Thus, the answer is simple diffusion.
Polygenic traits are those traits that are controlled by more than one gene (poly- means many). The examples for polygenic traits are eyes colour, hair colour, human height, etc.
Pleiotropic traits are those traits that are controlled by one gene. For instance, if one gene controls two different traits, then those traits are pleiotropic traits. The example is gene for phenylketonuria and sickle-cell anemia.
Knowing and understanding how different traits are controlled (by one or by many genes) is important for <span>linking human genotypes to phenotypes.</span>
