Answer:

Option). B the ductus venosus; D the ductus arteriosus

Explanation:

In fetal circulation, the structure that connects the umbilical vein with the vena cava is known as ductus venosus. It allows transfer of oxygenated blood to bypass the fetal liver from the placenta. In given diagram, it is represented by letter B.

The structure that connects the pulmonary artery with aorta is known as ductus arteriosus. It allows flow of blood to the aorta from pulmonary artery, which is then transported to placenta for oxygenation.  In given diagram, it is represented by letter D.

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.

The three bacterial shapes in Model 1 are referred to as coccus (sphere), spirillum, and bacillus (rod). Label the diagrams in M
Charra [1.4K]
<span>Bacteria keep their shape by having a rigid cell wall, but they can be shaped and appear differently. There are three main shapes of bacteria: 1.) The Coccus bacteria is in a sphere shape. 2.) Spirillum bacteria is in a spiral shape. 3.) The Bacillus bacteria comes in a rod shape. Each of these bacteria can come in pairs, clusters or chains.</span>
