Complete question:
Two species of closely related frogs are found in the same pond high in the Andes of South America. Both species only have teeth on the top jaw. One has small teeth for holding small live prey prior to swallowing. The other species has very large sharp teeth for injuring and killing large prey prior to biting off pieces of flesh for consumption. The above is an example of:
- Directional selection
- Analogous structures
- Character displacement
- Hybridization
- Vestigial structures
Answer:
Explanation:
Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.
The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When <u>two competing species coexist, this is because of niche partitioning or niche differentiation</u>.
Differentiation of effective niche is closely related to <u>character displacement.</u>
<u>Character displacement</u> is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.
In the exposed example, both species live in the same pond. But to avoid competition and competitive exclusion, species developed different teeth sizes to feed on different prey items.
I think it’s increase in gene flow
Hi you are cute thank you
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.

Answer:
Genus
Explanation:
In taxonomy, genus refers to a group of organisms that include one or more species that are closely related to each other. Organisms that are in the same genus share common features, characteristics, and/or traits but are not quite the same species. If a genus has only one species under it, it is called monotypic, but if there is more than one (which could reach more than 100 in some organisms!) it is called polytypic.
Right under genus would be species in biological organization. When naming organisms using binomial nomenclature, genus is first named, then species.
