What is the main difference between dispersal and vicariance?

Biology

Answer:

One involves the movement of the organism, and the other involves a change in the environment.

Explanation:

Most phylogenetically related groups have distribution patterns resulting from dispersion or vicariance. In the first of these processes, the most recent common ancestor of a given group of organisms originally occurred in only one of today's occupied areas, then dispersed to other areas - overcoming pre-existing barriers - in which descendants survived. In the occupied areas, differentiation processes may occur resulting in the formation of new species.  In vicariance events, the ancestral population occupied, to some extent, the sum of the areas currently inhabited by their descendants, and was divided into smaller populations by the emergence of barriers that caused isolation between subpopulations. The appearance of the barrier causes the disjunction (separation) observed and corresponds to an event that affects all or most of the biota.

From this we can conclude that the main difference between dispersion and vicariance is that one involves the movement of the organism and the other involves a change in the environment.

Sorry for your wait! The second choice “ large scale insulin can be produced in relatively lesser time” seems to be the correct answer.

Since this bacteria can produce insulin identical to that which humans make, we could quickly and more effectively produce more of it at a more rapid rate.

I hope this helped! If it did, would you consider marking my answer Brainliest?

Vladimir79 [104]

Answer:

This should be the case ( YES )

Explanation:

This should be the case and

It would be objective as logical for adhesins to be glycoproteins and receptors to be protein as well and this is because adhesins ( cell surface component) fastens bacteria to their host body ,and they can be seen as glycoproteins because The structure of Adhesins are mostly made of structural protein

Glycoproteins are proteins which contain glycans.

Will yall please help me (agriculture)
choli [55]

Answer:

Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive, or poorly timed application of pesticides, irrigation water, and fertilizer. Industrial farming practices, such as monocropping and intensive tillage, have also compromised soil health over time. ... Excessive fertilizer use can also cause a buildup of salts in soil, heavy metal contamination and accumulation of nitrate (which is a source of water pollution and also harmful to humans

Explanation:

However agriculture is both cause and victim of water pollution. It is a cause through its discharge of pollutants and sediment to surface and/or groundwater, through net loss of soil by poor agricultural practices, and through salinization and waterlogging of irrigated land.
