Answer:
Bacteriocins
Explanation:
Bacteriocins are the toxic proteins that are synthesized and released by the bacteria that are the part of the normal microbiota. These proteins have a molecular weight of 900 to 5800 Daltons. The bacterial species that release the bacteriocins are resistant against it.
Secretion of bacteriocins is an adaptive feature as these toxic proteins do not allow the growth of other strains of the same species or related species. One of the examples of bacteriocins are colicins that are released by <em>Escherichia coli</em>.
Answer:
a
Explanation:
In the case of the light bulb, electrical energy is being transformed into light and thermal (heat) energy. Different wattages and types of bulbs give off varying amounts of light and heat.
Answer:
B) All DNA molecules will migrate up the gel toward the positive electrode.
Explanation:
Because the DNA has a negative charge - regardless the size-, all DNA molecules will migrate towards the positive electrode, at the top of the gel. This is due to the Coulomb's physic law "force of the interaction between the charges is attractive if the charges have opposite signs".
Instead of migrate down the gel , the DNA will do migrate up the gel (opposite direction).
