Was it beneficial or harmful for the Balanus barnacle to add the Chthamalus barnacle? Explain
densk [106]

Answer:

harmful. (more info below)

Explanation:

Balanus may compete with Chthamalus through crowding or smothering, but Chthamalus can inhabit higher tide levels than Balanus since it is more immune to desiccation. Lower on the sea, the barnacles of acorn combine with the Endoclades (Turfweed) assemblage, and are also abundant on the shells of acorn. To conclude, it was a bad idea is add the balanus barnacle to the Chthamalus barnacle becuase balanus barnacles can crowd Chthamalus barnacle.

hope this helped!

Describe the process of photorespiration. what is its effect on the rate of photosynthesis
Lynna [10]
Before the Siderian period the world had much less oxygen in it. Meaning, seas devoid of oxygen. Durring the Siderian the algae activity that signifies the period began to pump oxygen into the oceans. Allowing then unreactive metalic iron in the sea to be precipitated out into iron oxide. In the case of temperature being a culprit in the Siderian, most likely not. Unless you factor it into giving the agal life energy. Temperature does affect oxidation, but oxidation cannot occur without oxygen. The higher the temperature, the easier it is for oxygen to bond with iron, the lower, the slower it will react.

snow_lady [41]

Answer:

Part a : c is true, part b: c is correct

Explanation:

Since this new cell can grow in a non polar liquid, that mean that need to be surround with this kind of molecules, and inside will be similar because if not the water will never get out from the cell.

The phospholipid will form a lipid bilayer and since the external and the inner structure is a non polar environment, the bonding among the lipids will be covalent nature so it can flow in a non polar surrounding.
