Which of the following is classified as a noninfectious disease?

Psoriasis is a chronic skin condition that causes red, scaly patches on the skin. It is not contagious, and it is not caused by any microorganism. It is believed to be an autoimmune disorder where the immune system attacks healthy skin cells.

The vermiform appendix is a small, finger-like projection that extends from the cecum, which is the first part of the large intestine.

A spectrophotometer is an instrument that measures the intensity of light absorbed after it passes through a sample solution. With the spectrophotometer, the concentration of a chemical substance can be determined by measuring the intensity of light detected.

The pH scale is logarithmic, indicating that each whole number change on the pH scale represents a tenfold change in acidity or alkalinity. Therefore, a substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4.

Most of the carbon dioxide from the blood moves into the alveoli through the process of diffusion down a concentration gradient. In the lungs, there is a higher concentration of carbon dioxide in the blood compared to the alveoli. Its molecules, therefore, move from an area of higher concentration (blood) to an area of lower concentration (alveoli) until equilibrium is reached. This is a passive process and does not require energy or carrier proteins.

Concentration of H+ in the solution = 10 −1 M

pH= -log(10 −1)

pH= -(-1)

=1

This is the plate with the most growth despite the presence of antibiotic cover.

The experienced mountain climber is replicating the conditions of the past expedition to understand why that earlier attempt was unsuccessful.

Water has a high specific heat capacity, which means it can absorb and store a large amount of heat energy without significantly changing in temperature. This helps moderate the temperature fluctuations of the air near the coast, as water can store heat during the day and release it at night, or vice versa.

The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

3' TCGATCGCA 5'
