Answer: a. the lowest trophic level
Explanation:
The keystone species is the one on which the entire ecosystem depends upon. It maintains a balance in the ecosystem. If this species is removed the ecosystem will drastically change. The members of the keystone species are abundantly available at the lowest trophic level. This will help in making a balance in a community or ecosystem. If some members die others will be available to survive others.

Answer with Explanation:
The large sample size allowed Gregor Mendel to make comparisons quantitatively. The <em>"margin of error"</em> is narrower and it allowed him to<em><u> detect statistically significant results</u></em> through its statistical power.<em> Large sample sizes have a greater statistical power.</em> However, it takes a lot of t<em>ime, effort and money.</em> Mendel was very persistent and had the driving force. This allowed him to develop the<em> "Three Principles of Inheritance." </em>
A smaller sample size doesn't give a significant difference because the samples are quite random. This has a<em> tendency to mask the result.</em>
I believe the answer is: A) do you reaction that causes a firework to explore requires less energy just start and occurs more rapidly than the reaction that causes the candle to burn
The energy needed to start the reaction should be shown by the bump at the begining of the reaction. The bump shown by blue line(candle) is much higher than bump made by the orange line(firework).
The y segment of the graph showing the time. The reaction of firework also happens more rapidly which shown by the fact that the orange line(firework) is always on the left of the blue line(candle).
Answer:
C) eukaryote A) bryophyte D) moss B) seedless plant
Explanation:
According to Whittaker five kingdom classification, the most specific classification includes prokaryotes and eukaryotes . Unicellular organisms were placed under Monera whereas Multicellular organisms were placed under Eukaryotes. Based on the cell wall, Eukaryotes were further divided into plantae and animalia. Plantae includes Thallophytes, Bryophytes (lacks differentiation of stem, leaf and root), Pteridophytes (seedless vascular plants), Gymnosperms (naked seeds) and angiosperms (Flowering and non- flowering plants).
