Answer: option B) Statement is false
Explanation:
Living things are NOT composed only of organic elements. Organic elements refers to compounds of Carbon, whereas living things such as Vertebrates (man, shark, lion etc) possess bones, teeth with INORGANIC components like phosphorus, magnesium, calcium.
Also, nonliving things are NOT made up of only inorganic elements. A good example is the air we breathe, it is non-living, yet contains carbon in the form of Carbiondioxide.
Answer:
One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.
Explanation:
In order to survive the winter, monarch butterflies "migrate to warmer areas".
<u>Option: B</u>
<u>Explanation:</u>
- The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
- This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
- Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
- If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
