The answer could be a fracture. Hope this helps!!
Plants have the cell wall and the chloroplast. Animal cells share everything else in the cells.
The Parasympathomimetic<u> </u>branch of the autonomic nervous system is activated by the family of pharmacological drugs known as parasympathomimetics. Agonists are two types of medicines.
The main neurotransmitter of the parasympathetic nervous system, acetylcholine (ACh), is mimicked or modified by parasympathomimetic medications to have their desired effects. Depending on whether they are direct or indirect agonists of acetylcholine ACh, parasympathomimetic drugs fall into one of two basic types. While indirect agonists raise synaptic levels of Acetylcholine ACh by decreasing the enzyme acetylcholinesterase, direct agonists directly bind and activate muscarinic ACh receptors.
Providers of healthcare should keep an eye on patients receiving parasympathomimetic drugs to make sure the treatment has the desired therapeutic impact. Parasympathetic Patients must be continuously monitored by the provider for any potential side effects. Due to the overstimulation of acetylcholine receptors, an overdose may cause a potentially fatal cholinergic crisis. There are several different formulations of parasympathomimetic drugs available to treat acetylcholine. To cure glaucoma and induce miosis during surgical operations, for instance, topical formulations of carbachol and pilocarpine are available for ocular use. Neostigmine is administered parenterally to treat paralytic ileus and act as a bladder agonist.

DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen to DNA molecules treated with DNAase?
A) The purines would be separated from the deoxyribose sugars.
B) The pyrimidines would be separated from the deoxyribose sugars.
C) All bases would be separated from the deoxyribose sugars.
D) The two strands of the double helix would separate.
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Answer:
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Explanation:
The purines and pyrimidines of two DNA strands of a DNA duplex are held together by hydrogen bonds. Hydrogen bonds are not covalent bonds. The enzyme DNAase targets the phosphodiester bonds. These are the covalent bonds that join two deoxyribonucleotides of a DNA strand together. therefore, when a DNA is subjected to digestion with DNAase enzyme, the phosphodiester bonds will be broken that hold the pentose sugars of two nucleotides by a phosphate group.
Explanation:
Radio waves, like all__electromagnetic _____ radiation are fundamentally different than _mechanical_______ waves such as sound. Even though
they share many similar properties, sound waves require a_medium____,while__radio____waves do not. Sound is the___vibrations___ of molecules and caused by pressure waves. There are no molecules in a __vacuum___
So, sound cannot travel through a vacuum or outer space. Radio waves are electromagnetic waves. They are the vibrations of _electric____ and_Magnetic_______
fields and require no matter to vibrate through. So, radio waves__can___
travel through outer space or a vacuum.
Mechanical waves are simply waves that causes oscillation of a body to transfer energy through it.
Sound and electromagnetic waves are both mechanical waves. Sound is propagated as a longitudinal wave parallel to the source.
Electromagnetic waves are transverse waves that are propagated perpendicularly away from their source.
Sound cannot be propagated in a vacuum but electromagnetic waves are. They do not require a materials medium to be transported through.
