The development of plant and animal life in an area without topsoil; the development of biotic communities in a previously uninhabited and barren habitat with little or no soil.
Examples<span> of where </span>primary succession<span> may take place include the formation of new islands, on new volcanic rock, and on land formed from glacial retreats. In </span>primary succession<span>, the initial conditions are often times very harsh, with little or no soil present.

Good acceleration and maneuvering. Less surface area means less drag.
Example: lake trout
Answer:
D. A horse and a donkey are not of the same species
Explanation:
Two organisms can be said to belong to the same species if they are able interbreed to produce not just <em>a viable</em> <em>offspring</em> but also <em>a fertile offspring</em>. Members belonging to the same species should able to interbreed to produce offspring that are both viable and fertile, according to the<em> Biological Species Concept.
</em>
A<em> mule is a viable</em> <em>offspring</em> of a cross between a female horse and a male donkey. However, <em>the mule is sterile</em>. This plainly suggests that a horse and a donkey are not of the same species. Donkeys and Horses have different numbers of chromosomes.
Being versatile means that it can be used in many different ways, or has many different purposes.
Hope this helps and have a nice day! :)
Answer:
"T" X "t" yields offspring that are all heterozygous with genotype "Tt"
Explanation:
An Allele refers to either of a pair of contrasting genes.
So, "TT" being the same yeild just one allele (T), while "tt" also yield one allele (t)
So, the cross of the both alleles
"T" X "t"
yields offspring that are all heterozygous with genotype "Tt"
Thus, the crossing dominant tall plant height "TT" and recessive short plant height "tt" yielded heterozygous tall plants "Tt"
