The paravertebral ganglia are connected via spinal nerves inwhich region?

Biology
1 answer:
Alex777 [14]3 years ago
7 0

Answer:

Answer is thoracic region.

Explanation:

Paravertebral ganglia are subdivision of peripheral sympathetic nervous system , which is one of the part of autonomic nervous system found in mammals. Its components are superior and inferior mesenteric ganglia and celiac.

The spinal nerves are peripheral nerves arising from the spinal cord. These spinal nerves are altogether 31 pairs. 8 in cervical, 12 in thoracic, 5 lumbar, 5 in sacral, and 1 in caudal.

There are two types of spinal nerves composed of the sensory and motor fibres.

Nastasia [14]

Answer:

Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.Nucleic acid is an important class of macromolecules found in all cells and viruses.

How does prokaryotic cell division differ from eukaryotic cell division?
dedylja [7]
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.

An imaginary species of bears, fur color can be purple or gold. Gold is the dominant trait. How would the bear look if the gene
BARSIC [14]

Answer:

<h2>Gold</h2>

Explanation:

Assume Gold trait =P ,

Purple= p,

Given:

Gold (P) is dominant over purple(p), so P is dominant over p.

If the bear is homozygous pp ( recessive)  then bear will look purple,

If the bear is heterozygous Pp, then bear will look gold,

If the bear is homozygous DD( dominant), then the bear will look GOLD,

A phage is a virus that infects bacterial cells. A phage virus is shown above. What component of the phage virus is indicated by
Setler [38]

Answer:

<u>D) the nucleic acid (either DNA or RNA)</u>

<u />

Explanation:

Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.

The nucleic acids  are made up of nucleotides. These are  genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).

What are the similarities and differences between carrier proteins and channel proteins​
kvv77 [185]
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.

* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.

Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.

A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules

The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
