Progressive age-changes in metabolism and physicochemical properties of cells, leading to impaired self-regulation, regeneration, and to structural changes and functional tissues and organs.
"Catabolic pathway that breaks molecules into energy" is the process of cellular respiration.
Answer: Option C
<u>Explanation:</u>
The cellular respiration relates to the biochemical mapping through which cells liberate energy from the chemical bonds of food molecules and distribute that energy for life's basic processes.
Photosynthesis, which generates sugars from smaller molecules, is a mechanism to "build up" or anabolic. Conversely, cellular respiration breaks down sugar into smaller molecules and is a process of "breaking down" or catabolism.
Catabolic processes involve the degradation into simpler of complex molecules, releasing the chemical energy contained in those molecules bonds. Many catabolic pathways will absorb the energy used to generate ATP and control the all cell processes.

renal calculi to include apples or fresh fruit on his diet for these fruits are
low in phosphate or phosphorus. Moreover, patient should lessen sodium-rich food,
which include canned, packaged or processed foods and eating in fast-food
chain. Also, consuming too much animal protein, calcium and oxalate increases the
risk of developing phosphatic renal calculi.</span>
Answer:
The correct answer is option b, that is, a modification in the target of DNA gyrase, is an illustration of acquired resistance.
Explanation:
The activity of DNA gyrase gets inhibit by fluoroquinolones. The enzyme that combines with the DNA and prevents its supercoiling at the time of replication is termed as DNA gyrase. It is a heterotetramer, which is formed of two subunits of GyrA and two subunits of GyrB. Due to the mutation in gene gyrA, the development of resistance takes place in N. gonorrhea against fluoroquinolones.
Post mutation, gyrA exhibits lesser binding capacity with the fluoroquinolones, and thus, the development of resistance takes place within the bacteria against the fluoroquinolones. The phenomenon of the development of resistance taking place in any microbe against the specific antimicrobial agent for whom it was vulnerable before is termed as acquired resistance, thus, the given case is an illustration of acquired resistance.
