Not just in the term "cystectomy," but with any medical term that ends with "-ectomy," refers to the removal of an object from one's body (often surgically). I hope this helped !
Answer:
D. Yes, two hydrogen bonds could form between thymine and cytosine.
Explanation:
A hydrogen bond (often informally abbreviated H -bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group, particularly the second-row elements nitrogen (N), oxygen (O), or fluorine (F)—the hydrogen bond donor (Dn)—and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac).
The formation of stable hydrogen bonds depends on the distance between two strands, the size of the bases and geometry of each base. Stable pairings occur between guanine and cytosine and between adenine and thymine (or adenine and uracil in RNA).
One hydrogen bond could form between the C4 carbonyl group on thymine (a hydrogen bond acceptor) and the C4 amino group on cytosine (a hydrogen bond donor). Another hydrogen bond could form between N3 of thymine (a hydrogen bond donor) and the N3 of cytosine (a hydrogen bond acceptor). Note that the C2 carbonyl groups found on both bases are both hydrogen bond acceptors and therefore a hydrogen bond cannot be formed between them.

<h2><u>Answer:</u></h2>
The correct option is A ( Technology has advanced and improved over time.)
<h3><u>Explanation: </u></h3>
Advancement is advancing and associations over the entire world are feeling the impacts whether it's sure or negative. Anyway, the advances of development have positively affected the matter of master games.
Everything running from minute replays to tweeting your most adored capable contender, development passes on individuals a great deal closer to the delight than whenever in ongoing memory.
Advances in development have even made it functional for an individual actually side of the world to watch a specialist wearing event continuously that is happening in another country, globalizing sports.
