Answer: Tetracycline.
Explanation:
A plasmid is a small circular DNA molecule found in bacteria that is separate from the bacterial chromosome and replicates independently of it. They encode for certain genes that play a key role in antibiotic resistance. <u>Restriction enzymes are endonucleases that catalyze the cleavage of phosphodiester bonds in different regions located within a DNA strand</u>. PstI is an example of an endonuclease, it is a type II restriction enzyme produced by the microorganism <em>Providencia stuartii</em> that possesses a restriction target in double-stranded DNA dependent on an unmethylated, palindromic, asymmetric sequence, and in this example, it cuts the plasmid at a single site in the ampicillin-resistance gene. After that, the DNA is annealed with another fragment of DNA and this new recombinant molecule is used to transform <em>E. coli</em> cells. Transformation is a key step in DNA cloning because it occurs after restriction enzyme digestion and ligation treatments and transfers newly made plasmids into bacteria. <u>So these bacterias will have a new fragment of DNA, which still has a tetracycline resistance gene but it no longer has the ampicillin resistance gene because it was disrupted by the restiction enzyme</u>. Thereby, the antibiotic resistance phenotype is the tetracycline resistace.
Answer;
Natural selection
Explanation;
-Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.Genetic diversity allows the different organisms to have different physiological characteristics. Some of them provides them with genetic resistance, others don’t. The ones which are resistant survive the pesticide, others don’t ; this is known as natural selection.
-Those that are resistant will live longer and have a larger number of offspring (reproductive success). From one generation to another, there will be more and more resistant pests (because of their larger offspring), and less and less pests that are not resistant (because they tend to die young). If the selection process goes on, someday the pesticide will be useless (it will kill no pest).
Answer:
The correct answer is the green light.
Explanation:
Plant themselves have a green color pigment in their leaves called chlorophyll which absorbs visible light.
Pigments absorb mostly the red and blue color light and reflect green light. This the reason why plants appear green to us and least likely to make food. Most of the autotrophs contain this green pigment.
Thus, the correct answer is the green light.
Anaerobic respiration was very weak because the earth had no harmful chemicals in the air at the time
If a procedure is performed on a malfunctioning device and not on a body part, there is only one root operation available to use and that is revision. The spaces of a PCS code are called characters and are filled with individual letters and numbers called values.
<h3>
Which pcs root operation is used for an adhesiolysis when adhesions are freed from a body part they are restricting?</h3>
Release pcs root operation is used for an adhesiolysis when adhesions are freed from a body part that they are restricting. This is the ICD-10-PCS code for the dilation of a right femoral artery using an open approach. The International Classification of Diseases 10th Revision Procedure Coding System (ICD-10-PCS) has been developed as a replacement for Volume 3 of the International Classification of Diseases 9th Revision (ICD-9-CM). The development of ICD-10-PCS was funded by the U.S. Centers for Medicare and Medicaid Services (CMS)
