Hypotonic.

In hypotonic environment, the water moving into the Paramecium cell by osmosis. Paramecium cells regulate water through special organelles which are known as contractile vacuoles. Paramecium is a freshwater organism, which means a hypotonic environment is its typical ambience.

What is the similarity between toxicity caused by an overdose of acetylcholine or nicotine and by the use of ganglionic blockers
dem82 [27]

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.

Explain how covalent bonds and hydrogen bonds hold together a strand of DNA
Lilit [14]

Answer:

Covalent bonds appear inside every linear chain and connect bases, sugars, and phosphate groups.

Hydrogen bonds appear between two strands and involve the base from one strand with the base from another strand in the complementary pairing.

Explanation:

A covalent bond is a chemical bond formed by joining electrons of two non-metal atoms into one or more common pairs.

A hydrogen bond (X-bond) is a type of weak chemical bond based on electrostatic attraction between a hydrogen atom and a nucleophilic atom that contains free electron pairs.

Explain how random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism
Arada [10]

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
