Varvara68 [4.7K]

Diabetes insipidus is a disease characterized by excessive thirst and the excretion of large amounts of highly diluted urine, which can not be reduced by a reduction in fluid intake.

Diabetes insipidus is due to a deficiency of antidiuretic hormone or insensitivity of the kidneys to this hormone. This hormone causes water reabsorption via action on the distal segment of the nephron during dehydration.

Plasmids are small circular DNA molecules found in bacteria that replicate separately from chromosomes. Why are plasmids essenti
oksano4ka [1.4K]

Answer:

DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times.

Explanation:

Plasmids are the extra-chromosomal circular DNA present in bacterial cells. Plasmids are able to replicate themselves independent of genetic DNA. Their ability to self replicate allows them to maintain themselves in the bacterial cells. This is why plasmids are used as cloning vectors in recombinant DNA technology.

A gene of interest is isolated from the donor cell and is inserted into the plasmid. The recombinant plasmid is introduced into bacterial cells where it replicates the ligated desired gene and allows the gene cloning. For example, the human insulin gene is ligated with plasmid and the recombinant plasmid is introduced in <em>E. coli</em> where it replicates the human insulin gene and allows the production of desired copies of the gene.

<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

  • The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
  • Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

  • All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
    A semipermeable lipid bilayer makes up the cell membrane.
  • The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

  • The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
  • second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

Autoimmune disease can happen at many times due to many problems the body can have. If one thing goes wrong with your body, it can go to another.
