Which population dispersion pattern is most commonly seen in the field for most species?
laiz [17]
<h2><u><em>Types of Dispersion Patterns </em></u></h2>
  • <em>If you're hiking through a forest, you might notice that some species of plants - like certain flowers or bushes - seem evenly spaced, while others - like wild mushrooms - are clustered together in only certain parts of the habitat. </em>

<em> </em>

  • <em>Within any given plant or animal population, or group of individuals of the same species living in the same area, individuals can be spaced in different ways called dispersion patterns. There are three types of dispersion patterns.</em>
  • <em>Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. And in random dispersion, individuals are arranged without any apparent pattern. </em>
  • <em> </em>
  • <em>In natural populations, random dispersion is rare, while clumped dispersion, which we'll focus on in this lesson, is the most common pattern. </em>
  • <em> </em>
  • <em>Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. It can also be caused by social interactions between individuals. Additionally, in organisms that don't move, such as plants, offspring might be very close to their parents and show clumped dispersion patterns. Let's further examine each of these three reasons for clumped dispersion.</em>

Explain the differences between diffusion in an open system and diffusion across biological membranes.
mario62 [17]

Answer:

Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.

In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.

2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.

3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.

Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.

4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.

The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.

How does organic evolution differ from other forms of evolution?
matrenka [14]

Answer:  

 The organic evolution are basically different from all the other form of the evolution as, the concept of organic evolution explain the origin of the life. It is the events which basically involve in evolutionary development of many species.

It also specifically involve in the modification of various existing species in the nature not only focus on the new development.

According to the theory of the organic evolution, the world are not created it is evolved with the branch of the life science.
