Connell's famous barnacle experiment was initiated to learn more about competitive exclusion and distribution of branacle species. Barnacle species are distributed in distinct zones on the rocky shores of the Atlantic coast. The Chthamalus in upper intertidal zone; is a smaller species and the semibalanus in low intertidal zone which is a larger species. Chthamalus found in the higher physical stress and higher temperatures because the low tide levels causes them to be exposed to the extreme outside environment for longer periods of time than the semibalanus. Additionally barnacles can only feed while submerged and the higher up shore a barnacle is, the less it can feed and grow. The experiment wanted to understand why they lived this way.
Answer:
the answer is a
Explanation:
i did that test an a is right
<span>This statement is an example of a negative feedback: <span>The first enzyme in a reaction sequence lowers the activation energy of the reaction.
</span>In Biology, negative feedback always results in a reaction that has a decreased function. This type of feedback occurs as a response to a particular kind of stimulus.
Negative feedback is necessary because it lessens the overall output of a particular system; as this continually happens, the system begins to stabilize. In Biology, this is what any organic material always seeks to achieve, a level of stabilization known as homeostasis or equilibrium.</span>
Plants, humans, animals, and microorganisms is the answer to this question
The answer is:
From smallest to largest (within the organism):
Cell, Tissue, Organ, Organ System, Organism.
Explanation:
Groups of similar cells working together for a function are tissues. Similar tissues working together to perform a function make an organ. Similar organs with a common purpose are called an organ system. Multiple organ systems make up the organism.
Below the cellular level, there are organelles, molecules, atoms, and subatomic particles.
Above the organism, there are populations (all of the organisms of a species in an area), communities (all species in an area), ecosystems (the community and environment), and the biosphere (the Earth).
