Answer:
In its astrobiology roadmap, NASA has defined the principal habitability criteria as "extended regions of liquid water, conditions favorable for the assembly of complex organic molecules, and energy sources to sustain metabolism".
Explanation:
antagonism
When two hormones cancel each other out or have opposite effects it is called antagonism.
<h3>What is an example of antagonism?</h3>
- Traditional examples of antagonistic hormones include insulin and glucagon.
- In contrast to glucagon, which stimulates glycogenolysis, or the conversion of glycogen to glucose, insulin stimulates glycogenesis, or the conversion of glucose to glycogen.
<h3>What does the term "antagonistic hormones" mean?</h3>
- Antagonistic hormones are those that work to bring body circumstances back from extremes to within acceptable bounds.
- An illustration of how the endocrine system maintains homeostasis through the action of antagonistic hormones is the regulation of blood glucose concentration (by negative feedback).
<h3>How do antagonists to hormones function?</h3>
- Infertility, endometriosis, and uterine fibroids are just a few of the diseases that gonadotropin releasing hormone (GnRH) antagonists are used to treat in women.
- GnRH is a hormone released by the hypothalamus that is the target of GnRH antagonists, which stop it from functioning.

Explanation:
This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.
The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).
