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
Trees that drop their leaves in colder seasons, in order to conserve water.
Whelp, it is definitely not D.
I would say B.
there was no Paleogene period.

Answer:</h2>
The wavelength of <u>light</u>.
<h2>
Explanation:</h2>
The electromagnetic spectrum shows the parts of light orchestrated by their wavelengths. The range for the most part comprises of both visible as well as invisible light. Together, they are called electromagnetic radiation. They are electromagnetic in light of the fact that they comprise of both an electric field and an magnetic field, and these fields travel in wave and travel at the speed of light: 3.00 × 
m/s.
When the light gets scattered it gives out color in the form of VIBGYOR which is elaborately called as Violet, Indigo, Blue, Green, Yellow, Orange and red. These colors are arranged in the spectrum based upon the wavelength.
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".
