How can vaccinations prevent the onset of certain diseases or disorders? a) Vaccinations build up the body's hormonal balances. b) Vaccinations build up the body's ability to fight illnesses. c) Vaccinations build up the body's ability to cure tumors. d) Vaccinations build up the body's sensitivity to medications.

Answers

Answer:

B)

Explanation:

Vaccinations build the body's ability to fight illnesses by introducing a de-activated virus to the body, which then produces antibodies that can kill the virus. The immune system can then "remember" the viruses' structure for future encounters.

Which of the following accurately describes the pH scale? A. The lower the pH is, the more basic the solution is.
B. The lower the concentration of hydrogen ions, the higher the acidity is.
C. The greater the concentration of hydroxide ions, the higher the acidity is.
D. The greater the pH is, the lower the acidity is.

Answers

Well if you haven't found the answer yet it's D, as the pH scale goes from 0-14 where 14 is the most alkaline and 0 is the most acidic. Therefore as you go up the scale, the substance becomes less acidic.

Final answer:

The pH scale measures the acidity or basicity of a solution. The higher the pH, the lower the acidity and the lower the pH, the higher the acidity. It is based on hydrogen ion concentration.

Explanation:

The pH scale is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It ranges from 0 to 14. A solution with a pH less than 7 is acidic, one with a pH of 7 is neutral, and one with a pH greater than 7 is basic. Therefore, option D is the correct answer. The greater the pH is, the lower the acidity is. The lower the pH, the higher the acidity, and vice versa. This scale is based on the concentration of hydrogen ions (H+) and hydroxide ions (OH-).

Which description best explains Watson and Crick's DNA model? DNA is a single–stranded molecule that has nitrogenous bases toward its exterior. DNA is a double helix made of two strands linked together with hydrogen bonds. DNA is a double helix that contains nitrogenous bases toward its exterior.

Answers

The discoverers of DNA were not JamesD Watson and Francis Crick. They are the first scientist to formulate anaccurate description of the DNA’s (deoxyribonucleic acid) complex ,double-helical structure. They discovered that base pairing nucleotides mustbe; adenine and thymine; and cytosine and guanine. These base pairs are heldtogether by a hydrogen bond, atype of chemical reaction that s easy to breakand easy to reform. The statement is “DNAis a double helix made of two strands linked together with hydrogenbonds.”
