Answer:
The answer is D.
Explanation:
The way x-rays are produced is as follows; using a vacuum environment in a tube, the cathode is heated to a degree where it releases electrons, then these electrons collide with the anode releasing energy that create the x-rays.
All of the options are correct. Although the electron most likely won't stop, it will slow down and change direction after the collision. The law of conservation of energy is also applied in this situation, meaning that the kinetic energy of the electron released by the cathode will transfer to the anode to produce the x-rays. Most of the energy after the collision is converted into heat, which is why the metal used as the anode can heat up to 2000 degrees celcius.

Aminoacyl-tRNA synthetases recognize their specific amino acid by charge, size and R group and recognize the tRNAs that carry it by the nucleotide sequence .
Aminoacyl-tRNA synthetases are enzymes that attaches the appropriate amino acids on to its tRNA . These are also responsible for performing the first step of protein synthesis.
Answer:
All of the above are correct.
Explanation:
The plasma membrane is the selectively permeable membrane that allows the movement of some selected particles only. Different types of movement like diffusion, osmosis and active transport occurs in the body.
Glucose acts as the primary energy source of the body. Glucose can be reabosrbed in the body by the facilitated diffusion and by the secondary active transport as well depending on the site of the cell. Glucose can enter in the peritubular capillaries as well.
Thus, the correct answer is option (d).
The answer to this question is: Public health
People in public health working in a large population. They are not focusing on individual health like physician and clinician that works in a hospital. Most of their activity is to promote health. Some of them is making a nationwide policy about health.
