Well, Carbon has 4 Valence Electrons. I'm sure you know this, but valance electrons allow electrons to covalently bond with one another. The elements, when sharing the electrons, want to have 8 valance electrons. So carbon has 4 valance electrons so it can bond with itself, or another say 4 hydrogen [becuase hydrogen can live with 2 valance electrons]. Hope this helps. Remember: Electrons <3 8 valance electron bonds Carbon's 4 + Carbon's 4= 8 true love at first bond! OR Carbon's 4+ Hydrogen's 1 [x4] = 8 hope this help
<span>The uncovered fossils of fish and palm trees shows that Earth’s environment has changed. Due to climate change, animals and trees have adapt to it over time. Researchers have found that tropical fish species are likely to leave their homes and populate in cooler waters as the world heats. And the palm trees were found that have grown in Antartica because of the change in temperature.<span>

Answer:
This is false.
Explanation:
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. ... Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them.
False because the third line of defense is specific by identifying the foreign antigen and activating the antibodies that can bind to the invaders and eliminating the spread
