One primer attaches to the __ end of the gene region on the 5' to 3' strand, another to the ___ end of the gene region of the 3' to 5' strand. This was maybe not explicit in the video. 3’ and 5’ refer to the orientation of the DNA strand. The 3’ end is the end that has the OH group used for adding new nucleotides. The 5’ end is the end where a phosphate sticks out from the ribose. The two strands that make up the DNA molecule run anti parallel to each other. Synthesis is always in the 5’ to 3’ direction (because that is where new nucleotides attach), and the template strand is read 3’ to 5’ (because it runs antiparallel).
Answer:
Explanation:
This question is incomplete however during DNA amplification using polymerase chain reaction, the two primers attach to each DNA strand at the 3' end.
Two primers are used during this process; one primer each for the two complementary strands of DNA (that run antiparallel to each other). The 5' end of each primer is attached to the 3' end of each DNA strand regardless of the direction the strand is running (5' to 3' or 3' to 5'). This process of attaching the primers to the DNA strand is known as annealing.
To protect our rights, the Constitution divides powers between the federal government's branches. This principle is called "separation of powers." Each branch of government holds distinct but equal authority. For example, Congress has the power to create laws, while the president has the power to execute these laws. The preamble states the purpose of "securing the Blessings of Liberty." Our freedoms are secured when power is not concentrated in any single branch of government. This helps our government to provide for our needs while respecting our rights.
Answer:
Explanation below
Explanation:
Separation of powers is very important and crucial in federal type of government. This is helpful because it decentralized the power, and prevent one arm of government from being a dominating force.
It will help the government to provide the necessary and needed infrastructure for the citizens. This is because the conclusion will be reached with approval of all the arms of government.
Describe an example of a relationship between a cell organelle and a task a cell must perform
Answer: These organelles are like the organs in a human and they help the cell stay alive. Each organelle has its own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a Golgi apparatus that packages and distributes proteins.
An example of a relationship between a cell organelle and a task a cell must perform is: Mitochondria and transformation of energy by a cell.

Place the steps involved in burning coal to create electricity in the correct order.
Water boils, creating steam.
Coal is burned
Turbines generate electrical energy.
Moving steam turns turbines.
Answer and Explanation:
Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area. Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam. Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines. Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.Answer:
Coal is burned
Water boils, creating steam
Moving steams turns turbines

3. Explain how organisms can develop resistance to chemical disinfectants.
4. Describe how avoiding the use of antibiotics for viral infections can prevent the spread of antibioticresistance.
Answer:
1- the bacteriostatic effect refers to the fact that they stop the metabolism of pathogenic bacteria, which means that they do not reproduce, do not colonize and do not generate the disease.
Bacteria in order to trigger a pathogenic response need to comply with their metabolism and this does not happen in the bacteriostatic effect.
2- Broad spectrum antibiotics where the patient's life is at risk, difficulty swallowing or breathing, and in infections that involve many planes or we are facing an extremely complex buofilm.
Low-spectrum antibiotic, in mild, focal infectious diseases that do not compromise the systemic factor and are suspected of simple or little complex pathogens.
3-Through mechanisms and virulence factors that are transmitted between them. One mechanism is sporulation, the change of essential metabolite, among others.
4- Prevents the spread and resistance because it reduces the bacterial load of pathogenic bacteria that in the future could form bacteruphages.
Explanation:
Broad spectrum antibiotics cover many bacteria, that is, they kill many bacteria of different families and even characteristics, while low spectrum antibiotics are the opposite.

What are the atomic masses of
protons, neutrons, and electrons?
Answer:
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Explanation:
The nucleus contains protons, neutrons, and electrons, each of which has a mass of 1 amu. Neutrons are uncharged, while protons have a charge of 1.
Thus, Electrons circle the nucleus, having a mass of about 0 amu, and a charge of -1.
Atomic mass of a proton: A proton's atomic mass is about equal to 1.007276 atomic mass units (u), or 1.007276 amu.
Neutron: A neutron has a slightly larger atomic mass than a proton. About 1.008665 u or 1.008665 amu is what it is. Electron: Compared to a proton or neutron, an electron has a substantially lower mass. An electron has a mass of roughly 0.00054858 u or 0.00054858 amu.
Thus, The nucleus contains protons, neutrons, and electrons, each of which has a mass of 1 amu. Neutrons are uncharged, while protons have a charge of 1.

Explanation:
i just know it. i like science
Sugar produced in the process of photosynthesis to sent to the mitochondria, is used to produce energy in the form of ATP through the process of cellular respiration.
What is Cellular respiration?
Energy is produced in the body through the food we eat. The food is broken down into simpler substances which are absorbed by the cells and in the cells are used to produce energy.
Sugar is produced by the process of photosynthesis in plants which is sent to the mitochondria to produce energy in the form of ATP (adenosine triphosphate). The process of oxidation of food to produce ATP is called cellular respiration.
The process of cellular respiration consists of three processes which include glycolysis (breakdown of glucose into pyruvate), citric acid cycle, and the oxidative phosphorylation which produces about 34-36 molecules of ATP in the mitochondria of cell.
