Answer:
Explanation:
I think it is: acetylcholine (neurotransmitter) - motor neuron - contract
second question: diffusion because of opening of ca2+ channels
Pioneer species are found in area's undergoing secondary succession. For example ecosystems being established by: reducing a fire, deforestation; which quickly colonize open spaces supported by vegetation.
Answer:
A. transmission genetics
B. population genetics
C. molecular genetics
D. genomics
E. molecular genetics
Explanation:
Transmission genetics can be defined as the study of the mechanisms involved in the inheritance of genetic material by offspring from parents. This discipline started with the discovery of inherited characteristics in pea plants by Mendel (1865).
Population genetics is a subdiscipline of genetics that studies genetic variation within and between populations. Population genetics is an area that explains how allele and genotypic frequencies change across time, thereby this subdiscipline is closely linked to evolutionary biology.
Genomics is a broad area of genetics that studies the function, evolution, structure, function, mapping and comparison of genomes (i.e., the whole genetic material contained in each cell of a given organism). This discipline aims at understanding entire gene pools. Genomics includes different research areas including structural genomics, functional genomics, epigenomics and metagenomics.
Molecular genetics is a sub-discipline of genetics that studies the mechanisms involved in preserving the genetic material (i.e., DNA and RNA), and to understand how the structure and expression of the genetic material influence the observed variation among organisms.
<span>The migration routes of Homo sapiens reveal
that they went through many environmental and physical challenges but adapted
everything much quickly in comparison to the other animals. The evolution
allowed other species also to adopt these changes but it took them a long time
to fit in the new environment, a sub species of a species adopted the new and
the previous one could not, but Homo sapiens invented ways and tools to combat
and evolve much quickly. It included their living, dietary needs, clothing and
much more.</span>
