I believe the answer to be C: It grows a tube to travel to the style
A gated channel is an example of facilitated diffusion. A gated channel protein is a transport protein that opens a "gate" allowing a molecule to pass through the membrane (usually molecules too big to enter the cell by passing through the membrane itself).<span> </span>Gated channels <span>have a binding site that is specific for a given molecule or ion. (meaning only certain molecules or ions can enter the channel).</span>
Out of the following give choices;
a. All DNA strands
contained only the heavy nitrogen isotope.
b. Half of the DNA strands contained only the light nitrogen
isotope.
c. All DNA strands contained both heavy and light nitrogen
isotopes.
d. All DNA strands contained only the lighter nitrogen
isotope.
The answer is b. Meselson–Stahl experiment demonstrated the semi-conservative model of DNA replication.
When DNA is replicated, one strand of the new double
helix strand is the parent's strand while the other is the newly synthesized
one. This made the semiconservative model stand out over the other two, dispersive
and conservative models.
There us a 100 percent chance that her son will have color blindness because the son gets one of the mom's x chromosomes which will have color blindness because both of the mom's x chromosomes carry color blindness, and he only has 1 x chromosome, so he will definitely have color blindness.
