Answer: Option d

Explanation: Whenever any clinical trail is conducted then the complete process is kept unbaised.

What is diffusion? Include in your explanation "area of high concentration" and "area of low concentration". Does diffusion occu
Luba_88 [7]

Answer:

Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.

Explanation:

The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!

Explain the relationship between ocean circulation patterns and the marine food chain, and how
dexar [7]

Answer:

Ocean circulation patterns is directly linked with the marine ecosystem. El Nino event hinders the climate interaction of ocean.  

Explanation:

  • The disturbance in the ocean climate interaction transfers the essential nutrients into the deep down ocean leaving very tiny amount at the surface. It lacks the support to plankton growth.
  • Ocean circulation patterns can sometime make the ocean food ecosystem less productive.
  • El Nino event reverses the ocean current. Surface waters in the central and eastern Pacific Ocean become significantly warmer than usual during this event. So the drifting starts towards east direction (normally driven west).
