The answer is C, or Adaptations increase the chances that an individual will reproduce and pass its genes onto the next generation. Such traits then become more common within a population.

Yes this can potentially create a bias in a statistical
study because the word popular may be subjective. It should properly defined in
order for the study to be not biased.
The cell interior would experience higher than normal Na⁺ concentrations and lower than normal K⁺ concentrations.
<h3><u>Explanation</u>:</h3>
The membranes that contain high concentration of sodium potassium ATPase pumps are generally the excitable membranes. These are found in muscles and in neurons.
In normal scenario, the de polarised membrane has higher potassium concentration inside and higher sodium concentration outside it. Now as an impulse comes, the sodium channels open which creates sodium influx and then potassium channels open which let's potassium efflux. Then after the conduction of impulse is over, the membrane regains its de polarised state by the sodium potassium ATPase pumps which transfers three potassium outside the cell and two potassium inside the cell in exchange of an ATP.
Now if the ATP is non hydrolyzable, then the pump won't occur. This will lead to greater sodium inside the cell and greater potassium outside the cell but the change difference will be nil on both sides.
Considering the multiple choice;
A. Require the correct external signal to replace
B. Start to develop new receptors in adaptation to their new environment.
C. Differentiate non-randomly only when specific hormones are present.
D. develop receptors in a random fashion.
Answer;
A. Require the correct external signal to replace
If only the deterministic hypothesis is correct, undifferentiated stem cells isolated from bone marrow and grown in vitro will
Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo.
Embryonic stem cells are pluripotent, meaning they are able to grow, into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm.
