Always contain Carbon
The majority of organic compounds contain carbon, hydrogen, and occasionally other elements such as nitrogen, sulfur, oxygen, or phosphorus.
<h3>What are Organic compounds ?</h3>
Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
- The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.
- Carbon is the key element because it has four electrons in an outer electron shell that can hold eight electrons

Explanation:
Environmental contamination reduces total testosterone oxido-reductase activity in females.- <u>True</u>
Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme testosterone oxi-reductase facilitates the of testosterone to the androgen DHT. Enzyme specificity is affected by pH, temperature and the presence of inhibitors.
In temperatures beyond its optimal range, these may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. Testosterone would no longer be able to bind to the active site, and thus would not be converted.

<h2>Tetrapods</h2>
Explanation:
d. All of the above
Tetrapods include animals who have four limbs.
Tetrapods are thought to evolve from aquatic ancestors, and primarily inhabited shallower waters before they completely migrated to land. This transition has fascinated the scientists and created a wild field for evolutionary studies.
Phylogenetic analysis prove that, tetrapods are advance and more complex than non-tetrapods, they are more evolved than non-tetrapods and are closely related to each other.
Answer:
smog
Explanation:
dew,clouds and fog are produced by condensation while smog is a kind of air pollution
Explanation:
Los prokaryotes son células simples y pequeñas, mientras que las células eucariotas son complejas, grandes estructuradas y están presentes en billones que pueden ser de células simples o multicelulares.
