Calcium oxide is an ionic, chemical compound created by equal transfer of atoms. As described, calcium loses two electrons, giving it a +2 charge and an atom of oxygen picks up two electrons, giving it a –2 charge. This event is called ionic bonding where there’s a complete transfer of valence electrons between atoms. Usually, metals are the ones donating their valence electron (e.g. calcium) and it’s the non-metals who accepts the donated electrons (e.g. oxygen).

<h3>What are Androgens?</h3>
Androgens are crucial for male growth as well as the preservation of secondary masculine traits such spermatogenesis, muscular mass, bone mass, and body composition. Steroid androgens' unfavorable physicochemical and pharmacokinetic characteristics are their principal drawbacks. With benefits like oral bioavailability, flexibility of structural modification, androgen receptor specificity, tissue selectivity, and the absence of steroid-related side effects, nonsteroidal selective androgen receptor modulators (SARMs) offer a promising alternative to testosterone replacement therapies.

Answer:
<u>3. Hot spots , 4. S shaped mid oceanic ridge, pacific ocean</u>.
Explanation:
- The Hawaiian islands are located on the hotspots that are formed by the collision of two strong plates and the presence of volcanoes and high magnitude earthquakes as the pacific plate is continuously moving on the western side as its subducting under the North American plate and hence shrinking in size.
- The s-shaped Atlantic ocean has mid atlantic ridge and as this ocean spreads the lava is up welding across the ocean floor and hence the opening of the atlantic plate is seen.
D, would be the correct answer because it would help you be more active than to be stiff.
