Yes all information about DNA above is right , DNA stores<span> biological </span>information<span> in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.</span>Dna store information which is dependent on genetic code , which dependent on the genetic code. The code which define relation between the sequence of bases in DNA (or its mRNA transcript) .Every cell in the human body carries a bundle of DNA in its
nucleus — nearly 30,000 genes, and the chunk fromdna become proteins.. Each of the 46 chromosomes in a human
cell’s nucleus bears thousands of genes.
Explanation:
In neurology, postganglionic nerve fibers are autonomic nerve fibers from the ganglion to the effector organ. These, unlike preganglionic fibers (whose sole neurotransmitter is acetylcholine) have a variety of neurotransmitters to fulfill their functions.
Neurotransmitters
The neurotransmitters of postganglionic fibers are varied, and are distributed as follows:
In the parasympathetic nervous system, neurons are cholinergic (Acetylcholine is the primary neurotransmitter)
In the sympathetic nervous system, neurons are mostly adrenergic (norepinephrine-epinephrine and / or norepinephrine, both have the same chemical structure, but epinephrine has a methyl group unlike norepinephrine that has a hydrogen, instead of a methyl group - act as the primary neurotransmitter) Two exceptions to this are the sympathetic innervation of the sweat glands and the piloerector muscles where the neurotransmitter in both pre and post ganglionic synapses is acetylcholine and in the vessels of the renal cortex where dopamine is used as the main neurotransmitter. Another exception is the sympathetic innervation of the medulla of the adrenal gland, which is innervated by preganglionic fibers, and subsequently uses acetylcholine as a neurotransmitter. Adrenal medulla cells are, in fact, modified postganglionic neurons that secrete epinephrine and norepinephrine directly into the bloodstream rather than a synapse.
In both divisions of the autonomic nervous system, postganglionic neurons express nicotinic acetylcholine receptors to receive signals from preganglionic neurons.
The pacific ocean, as that is how you know where this is.
Answer:
Option-C
Explanation:
Traditional ecological knowledge is the knowledge acquired and adapted by the local or native people living in a particular area.
The traditional knowledge is gained by the holistic approach of gaining the knowledge that is which benefits survival and increases the chances of well being.
The approach aims at learning by making direct contact with the surrounding environment, learning its ways, understanding the relationship between the various factors and then adapting to the condition and utilizing the available information.
The traditional way aims at looking at the environment in whole but the modern way of understanding the environment aim by learning the environment in the components.
The traditional knowledge is always shared by the local people in their local language but since the ideology of gaining the knowledge differ in both the ways and TEK is shared in local language therefore sometimes the knowledge does not prove useful in the contemporary world.
Thus, Option-C is correct.
Answer:
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium, magnesium, calcium, strontium, barium, and radium. The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
