Autonomic nerves synapse outside the central nervous system.
True or False
Answers
False. Autonomic nerves do not synapse outside the central nervous system.
Autonomic nerves are part of the autonomic nervous system (ANS), which regulates involuntary bodily functions such as heart rate, digestion, and respiratory rate. The ANS is divided into two branches: the sympathetic nervous system and the parasympathetic nervous system.
Both branches consist of a two-neuron chain, which includes a preganglionic neuron and a postganglionic neuron. However, the location of synapses differs for each branch.
In the sympathetic nervous system, the preganglionic neuron originates in the intermediolateral cell column of the spinal cord's thoracic and lumbar regions.
The preganglionic neuron's axon synapses with the postganglionic neuron in ganglia located outside the central nervous system. These ganglia form a chain that runs parallel to the spinal cord.
In the parasympathetic nervous system, the preganglionic neuron originates in the cranial nerves (such as the vagus nerve) or in the sacral region of the spinal cord.
The preganglionic neuron's axon typically synapses with the postganglionic neuron in ganglia located close to or within the target organ.
This means that in the parasympathetic system, the synapses occur closer to or within the target organ, rather than outside the central nervous system.
In both branches of the autonomic nervous system, the synapses between the preganglionic and postganglionic neurons occur either within ganglia located outside the central nervous system (sympathetic) or close to the target organ (parasympathetic).
Therefore, the statement that autonomic nerves synapse outside the central nervous system is false.

some cells may not have class i mhc proteins on their surfaces due to a viral infection or because they have become cancerous. how does the immune system respond?
Answers
The immune system's response if the cell does not have the MHC Class I protein is by activating natural killer cells that will attach directly to foreign cells in the body.
What is the role of MHC in the immune response?Two types of MHC molecules characterize the body's cells, namely MHC class I found in all nucleated cells in almost every cell of the body. Meanwhile, MHC class II is limited to a few specialized cell types including macrophages, B cells, activated T cells, and cells that make up the interior of the thymus.

The immune system is a group of proteins in the blood that attack pathogens that enter the body and kill them
The immune system represents a collection of tissues, cells, and proteins that cooperate to protect human body from outside pathogens like bacteria, viruses, and fungi. The specific system has a group of proteins in the blood called the complement system that plays an important role in recognizing and destroying pathogens. The complement system consists of proteins that circulate in the blood and work together to attack and kill pathogens in a process of activation.
The complement system can be activated by triggers, including antibodies, bacterial and viral proteins, and other proteins of the immune system. Once activated, the complement system can cause inflammation, attract immune cells to the site of infection and kill pathogens by making holes in their cell membranes.

neurons with one axon and several dendrites emanating from the soma are classified as:_________
Answers
Neurons with one axon and several dendrites emanating from the soma are classified as multipolar neuron.
A multipolar neuron is a type of neuron that has many dendrites (input regions), a single axon (output region), and multiple synaptic terminals. This type of neuron is the most common type found in the human body and is responsible for transmitting information between neurons and other cells throughout the nervous system.
Multipolar neurons are found in many parts of the body, including the brain, spinal cord, and peripheral nervous system. They are typically large and have a complex morphology that allows them to receive and integrate multiple signals from other neurons and sensory receptors. Dysfunction of these neurons can lead to a wide range of neurological disorders, including Alzheimer's disease, Parkinson's disease, and schizophrenia.

what material is found in the skeleton of all sponges
Answers
The skeleton of sponges, also known as Porifera, is composed of a variety of materials, depending on the species.
However, there is one material that is present in the skeleton of all sponges, and that is spongin.
Spongin is a type of protein that is secreted by specialized cells called spongocytes, which are found within the sponge's body.
This protein forms a network of fibers that provides structural support to the sponge's body.
The spongin fibers vary in thickness and arrangement depending on the species, and can be either flexible or rigid.
In addition to spongin, some sponge species have a mineralized skeleton made up of calcium carbonate or silica spicules.
However, spongin is the only material found in the skeleton of all sponges and is a crucial component of their unique structure and function.
Sponges are an ancient and diverse group of organisms, and their unique skeleton is a defining characteristic that sets them apart from all other animal groups.
The presence of spongin in the skeleton of all sponges highlights the importance of this protein in their evolution and survival.

DNA replication process is the event during which the molecule duplicates. It occurs in the interphase and involved different enzymes, a DNA molecule, and free nucleotides. Image attached.
Whatis DNA replication?DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.
The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated.
Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.
DNA strands are antiparallel, and replication occurs only in 5'-3' direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.
Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

The complementary DNA sequence for the parent DNA strand AGTCCATG would be TCAGGTAC.
In the base pairing model of DNA replication, the complement of adenine (A) is thymine (T), and the complement of cytosine (C) is guanine (G). Therefore, for every A in the parent DNA strand, there will be a T in the complementary strand, and for every C in the parent DNA strand, there will be a G in the complementary strand.
So, the complementary DNA sequence for AGTCCATG would be TCAGGTAC.

What are two differences between how isolated storms and cold front storms form?
Answers
The animators used the following to illustrate the difference between a warm and cold front: The warm one was a paint brush drawn over a piece of paper. The cold one was the brush pushed over the paper, curling as it moved.
A warm front is simply warmer air that rises slowly over colder one. It is long, perhaps some hundred miles long. It is slack. As the air rises, condensing its moisture, it causes the formation of strato-cumulus, drizzle then rain.
The cold front is much steeper because now, the cold air moves in from under, lifting the warmer one over much shorter distance. The air is unstable and causes gusty and shifting wind, rain showers, perhaps some isolated thunderstorms but, since it is colder polar air, the visibility is much better.
Warm and cold fronts occur when a mid-latitude low pressure moves eastward along the polar front, pushing the warm one and pulling the cold one.
Since the cold one is steeper and moves faster, it soon joins the warm front causing what is called, an occlusion front. It can be a warm occlusion, if the cold front rises over the warm one, or a cold occlusion if the cold front lifts the warm one.
