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.

Anettt [7]

Answer:

c. The starch stayed in the bag and the iodine leaked into the bag and the reacted with it, turning the solution black.

Explanation:

According to the given information, the solution inside the dialysis tubing has starch while water present outside has iodine. The color of the water present outside the dialysis tubing does not change which means that starch did not leak out of the bag and stayed in the bag itself. On the other hand, the starch solution present inside the bag turned black representing the fact that iodine entered the bag. The reaction of starch with iodine produces a blue-black color.

What is the definition of the length constant? What does the length constant tell you in terms of the electrical signal? Neurons
Furkat [3]

Answer:

The overview of the given problem is outlined in the following section mostly on explanation.

Explanation:

The constant length seems to be a constant value which used to measure the distance between the grade electron density and the neurite through passive electron flow.  The larger the quality of the distance constant, the faster the potential goes, throughout consideration of the electronic current.

  • The electronic replacement through one potential from neighboring areas including its cell will lead with the spatial description by a broad constant of length.  
  • This length decreases with either the size of that same neuron rising.
  • The length constant, means of characterizing how much continuous current that flows extends until it bursts out from the axon, despite constants of limited period meaning leakier axons.  
  • The resistance of that same membranes should be just as efficient as possible as well as the tolerance of its axoplasm or extracellular media must be weak to enhance the efficient movement of current via an axon.
