Because science is always changing and every time you cam come up with a new outcome.
<h3><u>Answer;</u></h3>
A. <em>18 hydrogen atoms </em>
<h3><u>Explanation;</u></h3>
- <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
- <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
- Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.
Both are hard structures that reduce erosion causes by waves.
Answer:
The exponential growth model shows a characteristic curve which is J-shaped while the logistic grown model shows a characteristic curve which is S-shaped.
The exponential growth model is applicable to any population which doesn’t have a limit for growth. The logistic growth model is applicable to any population which comes to a carrying capacity.
The exponential growth model typically results in an explosion of the population. The logistic growth model results in a relatively constant rate of population growth. This happens when the growth rate of the population arrives at its carrying capacity.
Exponential growth is ideal for populations that have unlimited resources and space – such as bacterial cultures. Logistic growth is more realistic and can be applied to different populations which exist in the planet.
The exponential growth model doesn’t have any upper limit. The logistic growth model has and upper limit, which is the carrying capacity.
Exponential growth happens when the rate of growth is in proportion to the existing amounts. This is also true for logistic growth but the difference is, it also includes competition and resources which are limited.
