Both primary and secondary succession begin with pioneer species that
Elina [12.6K]

Answer:

  • The different zones or region on the planet may some times suffer great distress in creating the best ecologically suitable environment for all the living being, as there are various factors that come in to play such as the soil moisture, presence of humidity and moisture inside the air, and many other factors.Both primary and secondary succession begin with pioneer species that  enriches the soil and make it able for the living beings to develop itself in it and provide a suitable environment for life to flourish more frequently.    

Explanation:

  1. But, the two steps of successions involves the primary and secondary stage in a given form or procedure. As, the primary succession occurs inside the region which is left abundant due to some reason and there is less for the living being to gain from, so the land then faces the primary succession and many micro organism play a vital role in making the whole situation much better for the living beings.And the lithosphere is highly influenced by the actions of different associations that are formed for the growth of the land mass as a whole.
  2. Now, the secondary succession involves the covering of that specified piece of land by the presence of the specific number of species which would provide more diversity to the land mass and create a better ecological system for the living beings to live inside it.

Discuss the three theoretical models which describes structure of the DNA and describe the semi conservative replication of the
sattari [20]

Answer:

Three theoretical models for the replication of DNA had been proposed in the past. Out of these, the method of semi-conservative replication is most widely accepted.

Conservative replication: In this method, no DNA unwinding takes place. The parent DNA gives rise to daughter DNA.

Dispersive Method: In this method, the chains in the DNA molecule break and recombination occurs randomly. The daughter and parent strands will have segments of recombinant DNA.

Semi- conservative: In this method, the two strands of the double helix unwind. Each strand acts as a template for the synthesis of a new strand.

DNA replication is more complex in eukaryotes as compared to prokaryotes. Prokaryotes have a single point of origin from where the replication begins. Eukaryotes have multiple points of origin. Eukaryotic cells have a unidirectional method of replication whereas prokaryotes do not. Prokaryotes just have two polymerases whereas eukaryotes have more than four. The replication rate is faster in prokaryotes.

Describe the actor-observer bias and explain why it occurs.
Helga [31]

Answer:

Responses may vary but should include some or all of the following information:

The actor-observer bias is a form of attribution bias in which a person is more likely to make an external attribution for behavior when acting and more likely to make an internal attribution for behavior when observing another.  The actor-observer bias likely occurs because individuals are more likely to understand the constraints under which they act but are less likely to understand what constrains others.

Explanation:

I took the test.
