Answer:
DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape
Explanation:
Sickle cell mutation is a mutation that affect the production of red blood cell that is needed for the transport of oxygen in the bloods stream.
sickle cell mutation is a result of change in the amino acid which are building blocks of the protein hemoglobin.
The protein is what gives red cells their color, it has two subunits. The alpha
and beta subunit. There is a change in the arrangements of amino acid sequence and that is the basis for the sickle cell shape, beta subunit has valine an amino acid at position 6 instead of the glutamic acid. This alteration results in sickle cell problems that occur in people.
A neuroscientist would identify this certain process as "pruning", which means to trim or remove.
<span>An example of a good action which might have unintended bad effects is giving someone homemade bread that contains gluten. The baker did not have knowledge that the receiver had gluten allergies thus leading to unintended bad effects.</span>
<span>Diffusion is the movement of molecule from a place of high concentration to a place of low concentration through a semi-permeable membrane.
Osmosis is the movement of molecules from a place of high <u>water</u> concentration to a place of low water concentration through a semi-permeable membrane
So probably the answer is <em><u>C</u><u></u></em></span>
