Answer:
Sí, ya que su función es matarlas o impedir que aumente el número de estas.
Explanation:
Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.
Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.

Which of the following are factors that limit enzyme activity?
denaturation
increase in substrate
optimal temperature
increase in number of enzymes
According to the research, increase in substrate and temperature are factors that limit enzyme activity.
What are enzymes?It is a protein that catalyzes the biochemical reactions of metabolism and acts on molecules known as substrates.
The way that the enzyme has to carry out its catalytic activity will be in the first place to bind with the substrate, this is limited by different factors such as the concentration of the substrate and the temperature.
Therefore, we can conclude that according to the research, increase in substrate and temperature are factors that limit enzyme activity.

Sometimes new ideas in science come from traditional methods people used in the past. What did researchers learn from terra preta? How is bio-char different from the traditional Amazonian method of creating terra preta?
Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.
Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.
What is terra preta soil?Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.
Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.

The effect of carbon dioxide on the atmospheric temperature is BEST shown by graph
Answer: definitely C will help you
Explanation:
Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.
What is the main reason of emission of carbon?According to the information given in the question, we can state that global temperatures tend to increase as carbon emissions increase due to green house effect.
According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.
This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.
These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.
Therefore, Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.

Reactant
Product
Activation energy
Bond
Endothermic
Exothermic
Rate
A chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires a minimum amount of energy.
A reactant is a starting substance in a chemical reaction, whereas products are formed at the end of the reaction.The rate of reaction is the velocity of the chemical reaction.Activation energy refers to the minimum amount of energy required to activate reactants and thus start a chemical reaction. The chemical reactions store/release energy by destroying/building chemical bonds between atoms/molecules.Exothermic reactions release energy when the bonds are formed; whereas endothermic reactions consume energy.In conclusion, a chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires energy. These reactions can be exothermic processes or endothermic processes.
