The agriculturally important microorganisms come from bacteria, actinomycetes, blue green algae, fungi, including vesicular arbuscular mycorrhizae and viruses. They thrive in a variety of habitats including soil, living body systems anddecayed matter, marine, snow bound mountains and desert systems, along with water bodies.
They help transmit information between cells of the brain and spinal cord. These are considered as essential fatty acids which are required for optimal health. Unfortunately, they cannot be synthesized in our body. It must be provided in our diet. They are also termed as polyunsaturated fatty acids. They have critical role in the maintenance of structural and functional integrity of the central nervous system. It is particularly important in the development of CNS during fetal life. This must be sustained during the infancy by giving the right and adequate nutrition. This essential fatty acids particularly helps in myelination, which allows conductions of nerve impulse to be fast through saltatory conduction.
Answer: Introduced species or exotic species
Explanation:
The introduced species is also called as an exotic species. The exotic species is a species which is not native to a particular location or area but is introduced by humans either accidentally or with the desired species. Such species can be invasive means, it can compete with the native species for resources and can reduce the population of native species.
The given situation is an example of introduction of new species. The weeds are introduced exotic species which could have come along with the desired variety of wheat required for farming in the prairies.
Answer:
Polar molecules occur when there is an electronegativity (a charge) difference between the bonded atoms. Nonpolar molecules offur when electrons are shapred between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Explanation:
Or basically, polar molecules occur with a charge, as nonpolar molecules do not. And yes, lipids are molecules.
