Describe two biologically important features of diffusion

Biology
1 answer:
Aleonysh [2.5K]4 years ago
8 0
Diffusion is the process in which movement of molecules take place from their higher concentration to their lower concentration. It is an important biological process in any living organism. Two of these are:
1. It allows the exchange of molecules within the organism and with the environment. For example: gaseous exchange in the alveoli of the lungs.
2. It also regulates water content in the body.

If a rock is in a stream for a long period of time, explain how it might experience weathering, erosion, and deposition. Use RAR
frutty [35]

Explanation:

It is expected that the rocks in a stream will eventually be transformed into a sediment and deposited in the same basin or carried away.

  • As the rock body inside the water begins to absorb water, it will eventually undergo chemical weathering.
  • Rock chips from other bed-loads carried by the flowing stream will cause the breaking down of the rock mass in the stream mechanically.
  • The above processes are classified as weathering.

The stream can erode its own bed causing the washing away of the weathered rock materials. Stream erosion occurs when weathered materials are washed away either in solution or as bed load moving on the base of the stream.

During transportation, the materials are carried away to nearby basins where the sediments are deposited under gravity.

Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determinatio
mamaluj [8]

Answer:

One allows microbe to move in the medium and the other allows to see it.

Explanation:

Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.
