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.

1. All animals except sponges have , groups of cells that work together to perform a specific function. 2. All animals eat other
ValentinkaMS [17]

Answer:

1. Tissues

2. Heterotrophic

3. Body cavity

4. Eukaryotes

5. Radial symmetry; bilateral symmetry.

Explanation:

1. All animals except sponges have tissues, groups of cells that work together to perform a specific function.

Sponges are sea animals which are found attached to surfaces. They are multicellular and heterotrophic like other animals, but they lack true tissues and organs.

2. All animals eat other organisms in order to gain building materials for the body. This makes them heterotrophic, since they obtain necessary energy and chemical building blocks from the environment.

Heterotrophs are organisms that cannot manufacture their own food, but obtain it from their environment instead.

3. One key adaptation of animals was the evolution of a body cavity, a fluid-filled gap between the outer wall of the body and the outer wall of the digestive system.

A body cavity is a space found inside the body that is filled with fluid and which holds and protects internal organs. There are several cavities found in the human body and they are separated by membranes as well as many other structures.

4. All animals are eukaryotes, organisms with cells that are relatively large, complex, and contain membrane-enclosed organelles such as the nucleus.

5. Cnidarians are the only animal phylum to display radial symmetry, meaning that their bodies can be divided any way through the center point to yield two even halves.All other adult animals display bilateral symmetry, meaning that their bodies can only be sliced lengthwise through the midline to produce two even halves.

Once the newly made spring has been hardened, what temperature should it be drawn to?
bagirrra123 [75]

Temperature should it be drawn to 600°-650° Fahrenheit for the newly made spring has been hardened

  • Hammer, sear, and trigger are the three main parts of a trigger mechanism.
  • . Single-stage trigger is used on the Winchester Model 94 and Marlin Model 336 rifle.
  • Lapping is the process called that entails rubbing minute amounts of metal from surfaces that must be precision-finished.
  • . Gray to dark blue color would be observe if we  achieved the desired drawing temperature of 600-650° Fahrenheit.
  • Thermocouple pyrometer is the most common instrument for measuring high temperatures in heat-treating furnaces.
  • Cherry to bright cherry color would be observe by  reaching  the temperature of 1,400°-1,500° Fahrenheit.
  • Once the newly made spring has been hardened 600° -650° Fahrenheit temperature would observe.
