Answer:

plasma membrane of the target cell

Explanation:

There are two main types of acetylcholine (ACh)receptors:

  1. muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
  2. nicotinic ACh receptors (nicotin is agonist) which are  ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).

  • Photography
  • Alternate Light Source
  • Cyanoacrylate

Determination of fingerprints is an important method used in forensic science.  There are generally three types of fingerprints that are to be determined, namely latent fingerprints, patent fingerprints and plastic fingerprints. There are numerous methods used for the determination of fingerprints. However, most commonly used methods are:

<u>Photography:</u> Photography is direct or straightforward method that is used to determine the patent fingerprints. The image is photographed in a high resolution with the help of forensic measurement scale used as a reference.

<u>Alternate Light Source Method:</u> In this method the light source or LED is used of a particular wavelength in order to determine the latent fingerprints.

<u>Cyanoacrylate:</u> Cyanoacrylate processing is also known as super glue method or fuming method, which involves exposure of cyanoacrylate vapors to the non-porous surface from where the fingerprints are to be obtained.

Ecology and evolution are closely related, as are evolution and genetics. All have an impact on the world around us.
PtichkaEL [24]

Ecology is the science that studies the interaction between living beings and the environment in which they live.

<h3>How can I help with conservation?</h3>

  1. Buy recycled paper avoiding the death of more trees
  2. Have a recycling bin for paper, plastic, metal and glass, to reduce the environmental damage in waste and for the waste to be reused
  3. Recycle toner and ink cartridges from empty printers, to avoid polluting rivers and streams.
  4. If possible buy remanufactured cartridges, avoiding environmental impact
  5. Recycle old newspapers, avoiding the death of more trees.

<h3>What is the evidence for evolution?</h3>

  1. Anatomy. Species may share similar physical features because those features were present in a common ancestor (homologous structures).
  2. Molecular biology. DNA and genetic code reflect the common ancestry of life

With this information, we can conclude that Ecology is concerned with the living beings on the planet and their relationships with each other and with the environment.
