I don't understand, what is the question you're supposed to answer?
A chromosome is DNA wrapped around proteins knwn as histones. A gene is a part of the DNA that codes for a particular protein
The dialysis tubing and cell membrane are similar in the fact they protect the cell. The tubing as well as cellmembranes are selectively permeable, they control the movement of substances in and out of the cell. Starch molecules are larger than glucose molecules.
You'll want to double check, but I think it's (a) cotyledon.
<span>Testosterone achieves his effect by binding to his androgen receptor (nuclear). Because testosterone is steroid hormone (derived from cholesterol), it has a possibility to free diffuse through the cell membrane. When testosterone binds, the receptor undergoes a structural change which allows it to move into the cell nucleus and dimerize. Receptor dimer than binds directly to the specific sequence of the DNA called hormone response element (HRE) which results in regulation of gene expression.</span>
