Answer:

OH, H2O2 and O−2

Explanation:

Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.

kodGreya [7K]

Answer:

B. Puerperium, or fourth trimester of pregnancy

Explanation:

  • Puerperium or the fourth trimester of pregnancy is also known as the postpartum period.
  • This period starts immediately after the mother gives birth to a child.
  • During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
  • It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
  • This phase is divided int three periods -

1. Immediate puerperium, or the first 24 hours after parturition

2. Early puerperium, which extends until the first week postpartum;

3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.

  • This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
