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.

One method for separating polypeptides utilizes their different solubilities. The solubility of large polypeptides in water depe
Otrada [13]

Answer:

Polypeptides are composed of amino acids, and we know amino acids are differently charged, have different R groups, and also have different isoelectric points. Depending on different isoelectric points and charged groups, the polypeptides can be separated and because a protein has its lowest solubility on its isoelectric point.

So in this question,

(a) (Lys-Ala)3 ; this is highly positively charged (polar) at pH 7 than (Gly)20 which is uncharged except for the amino and carboxyl terminal.

(b) (Glu)20 ; it is highly negatively charged at pH 7 whereas (Phe-Met)3 is much less polar and hence less soluble.

(c) (Asn-Ser-His)5 ; at pH 3, because in (Ala-Asp-Gly)5 the carboxylate groups of Asp residues are partially protonated and neutral, whereas in (Asn-Ser-His)5 , the imidazole groups of His residues are fully protonated and positively charged.

(d) (Asn-Ser-His)5; at pH 6.0; both polymers have polar Ser sidechains, but (Asn-Ser-His)5 also has the polar Asn side chains and partially protonated His side chains.

What is the difference between a transgenic plant and a plant produced through selective breeding?
bonufazy [111]

Answer:

Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. They are identified as a class of genetically modified organism (GMO).

Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics.

Explanation:

Using the definitions giving, so the difference would be that in transgenic plants they are created using DNA techniques such as electroporation, wherehas in selective breeding the plant is grown from naturally grown parent plants that are chosen through selection based on their superior character traits.

Hope this helps!!
