Atria is a large part of the heart so too big for cells; arteries & veins lead away or to the heart.
Capillaries are the smallest vascular structures that allow materials to be exchanged easily between cells.
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
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.
