Answer:
Proton and neutron
Explanation:
Electrons are very light, and don't really have a significant impact on the atomic mass
Answer:
Explanation:
To find molecules, we will need to multiply the number of moles of carbon monoxide by Avogadro's number. Avogadro's number is .
So the equation would look like this:
Like most liquids, mercury expands, or gets bigger, when heated. As the environment gets warmer, the expanding mercury inside the narrow glass tube of the thermometer has nowhere to go but up. When the temperature cools, the mercury slides back down the tube.
pH 3 = 10 times of pH 4 in terms of H⁺ concentration
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ion. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
So pH 3 and pH 4 have a difference in the concentration of H⁺ ion of 10¹ = 10
pH 3 = -log[10⁻³]
pH 4 = - log[10⁻⁴]
pH 3 = 10 times of pH 4 in terms of H⁺ concentration
And pH 3 is stronger in acid than pH 4
Answer:
A) That resistance in bacteria is produced due to inactivation of ampicillin by the beta lactamase enzyme. This enzyme is expressed by the bla gene found in the plasmid. This enzyme is secreted into the culture medium, thereby inactivating ampicillin. Thanks to this inactivation, the bacteria colonies will be able to develop. After a day of incubation, only those bacteria that took the plasmid that gives them resistance to ampicillin will grow after transformation. After prolonged incubation, two types of colonies can be observed in the culture medium. One large colony with ampicillin resistance, and another small colony, both of which are sensitive to ampicillin.
B) Large colonies are characterized by being resistant to ampicillin. When Ramón isolates the plasmid, he will have the gene that provides resistance to antibiotics. Said plasmid can be used again on those bacteria that are sensitive to ampicillin.
On the other hand, satellite colonies are sensitive to ampicillin. These types of colonies do not have the plasmid that contains the gene that gives ampicillin resistance. It is not possible to isolate any plasmids from these satellite colonies. These satellite bacteria will not be able to grow if they are transferred to a plate containing fresh ampicillin, while large colonies, which possess the plasmid that gives them resistance to ampicillin, will be able to grow on that plate.
