Answer:
La teoría atómica de Dalton fue el primer intento completo para describir toda la materia en términos de los átomos y sus propiedades.
Dalton basó su teoría en la ley de la conservación de la masa y la ley de la composición constante.
La primera parte de su teoría establece que toda la materia está hecha de átomos, que son indivisibles.
La segunda parte de su teoría establece que todos los átomos de un elemento dado son idénticos en masa y en propiedades.
La tercera parte de su teoría establece que los compuestos son combinaciones de dos o más tipos diferentes de átomos.
La cuarta parte de su teoría establece que una reacción química es un reordenamiento de átomos.
Partes de su teoría tuvieron que ser modificadas con base en el descubrimiento de las partículas subatómicas y los isótopos.
Fruits and vegetables are in the produce aisle because they are plants, and plants are producers.
Producers are organisms that create energy on their own through various processes depending on the organism.
Answer:
B and C Reduce Emissions and Least fuel economy
Explanation:
Plug-in electric vehicles are related, fun and practical (also called electric cars or hybrid electric vehicles). We will reduce emissions and save you even money. EVs deliver more than individual advantages. EVs will allow the US to have a more diverse range of transportation fuel options. Last year the US used almost nine billion barrels of oil, of which two-thirds went into shipping. We are vulnerable to price increases and supply disruptions because of our dependence upon oil. EVs help reduce this threat, as almost all US electricity, including coal, nuclear, natural gas and renewables, is generated from domestic sources.Vehicles can also minimize the CO2 emissions, improve health, and reduce environmental damage that contribute to climate change and smog. Charging your EV for renewable, such as solar or wind, will further reduce these emissions. Link to a calculator on the right to the pollution disparity between the traditional and an EV. Discover how EV reduce pollution and their emissions during their life cycle.
Answer : The length of protein will be, 36.8 A⁰
Explanation :
First we have to calculate the amino acid residue.
![\text{Amino acid residue}=\frac{\text{Length of single strand of protein}}{\text{Mean residue mass}}](https://tex.z-dn.net/?f=%5Ctext%7BAmino%20acid%20residue%7D%3D%5Cfrac%7B%5Ctext%7BLength%20of%20single%20strand%20of%20protein%7D%7D%7B%5Ctext%7BMean%20residue%20mass%7D%7D)
Given:
Length of single strand of protein = 27.0 kDa
Mean residue mass = 110 Da
![\text{Amino acid residue}=\frac{27.0kDa}{110Da}=\frac{27000Da}{110Da}=245.4](https://tex.z-dn.net/?f=%5Ctext%7BAmino%20acid%20residue%7D%3D%5Cfrac%7B27.0kDa%7D%7B110Da%7D%3D%5Cfrac%7B27000Da%7D%7B110Da%7D%3D245.4)
Now we have to calculate the number of turns in protein.
![\text{Number of turns in protein}=\frac{\text{Amino acid residue}}{3.6\text{amino acid per turn of the alpha-helix}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20turns%20in%20protein%7D%3D%5Cfrac%7B%5Ctext%7BAmino%20acid%20residue%7D%7D%7B3.6%5Ctext%7Bamino%20acid%20per%20turn%20of%20the%20alpha-helix%7D%7D)
As there are 3.6 amino acid per turn of the alpha-helix.
![\text{Number of turns in protein}=\frac{245.4}{3.6}=68.17](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20turns%20in%20protein%7D%3D%5Cfrac%7B245.4%7D%7B3.6%7D%3D68.17)
Now we have to calculate the length of the protein.
![\text{Length of protein}=\text{Number of turns in protein}\times \text{Length of each turn}](https://tex.z-dn.net/?f=%5Ctext%7BLength%20of%20protein%7D%3D%5Ctext%7BNumber%20of%20turns%20in%20protein%7D%5Ctimes%20%5Ctext%7BLength%20of%20each%20turn%7D)
As, we know that the length of each turn = 0.54 A⁰
![\text{Length of protein}=68.17turns\times 0.54\AA=36.8\AA](https://tex.z-dn.net/?f=%5Ctext%7BLength%20of%20protein%7D%3D68.17turns%5Ctimes%200.54%5CAA%3D36.8%5CAA)
Thus, the length of protein will be, 36.8 A⁰
Answer: The difference between rapid combustion and spontaneous combustion...
Explanation:
Rapid combustion is a form of combustion, otherwise known as a fire, in which large amounts of heat and light energy are released, which often results in a flame.Whereas spontaneous combustion is the ignition of organic matter (e.g. hay or coal) without apparent cause, typically through heat generated internally by rapid oxidation.
