What term is used to describe bacterial cells that can naturally take up dna from their environment?
Maru [420]
<h2>The correct answer is: Competent cells</h2>

Explanation:

  • Bacterial cells have the capability of incorporating foreign naked DNA or deoxyribonucleic acid fragments from the environment or the exterior of the cell to the interior of the cell. This process is known as Transformation.
  • The bacterial cells which are able to undergo transformation are called Competent bacterial cells.
  • Some of the bacterial cells are naturally competent like<em> Bacillus subtilis, Streptocossus pneumoniae</em> while others  like <em>Escherishia coli </em>need to be chemically treated to make them artificially competent.
  • In natural competence, the foreign DNA from the cell exterior is incorporated into the cell interior through specific protein complexes present in the plasma membrane of the bacterial cells.
  • In artificial competence, the negative charge on foreign DNA is masked by positively charged calcium ions (so that it is not repelled by the negative charge of the lipid bilayer of the bacterial cell plasma membrane) and then small pores are created in the lipid bilayer of the plasma membrane of the bacterial cells by giving a heat shock to the cells. This results in the uptake of the DNA by the bacterial cells.

What is the pathway of information through a neuron?
garik1379 [7]

Answer:

The pathway of information through the neuron is based in the connection of axons with other neurons, favoring the conduction of information from one place to another of the nervous system. The way in which a neuron communicates with another, with a receptor or an effector is called synapse.

Explanation:

Neurons are the specialized cells that allow the function of the nervous system, given by the transmission of information in the form of nerve impulses. The way in which information is transmitted by neurons depends on the connection that exists between neurons, by their axons and dendrites, or between enurons and specialized structures such as receptors and effectors.

When a stimulus reaches a receptor, it connects with the neuron that carries the information by afferent pathway to the central nervous system. Once the information is processed, a response is elaborated that travels through the neurons by efferent pathway to an effector cell.

Synapses are simply the connection that exists between neurons, through their axons, or from these cells to the receptor or effector structures. Synapses are located between one neuronal axon and another, or between axons and receptors or effectors, and occur through electrical signals or chemical mediators called neurotransmitters.
