Answer:
The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.
Explanation:
The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well. The change in the growth of E. coli is not able to detect by alizarin.
The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
The lymphatic system destroy harmful substances 'By producing antibodies'.
The lymphocytes contained in lymphatic organs are produced with other defence cells by the bone marrow. They are then dispersed to eliminate pathogens.
Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical) or the order of nucleotides (biological evidence).
<h3>What is scientific evidence?</h3>
Scientific evidence refers to the observations that can be used to support (or reject) a working hypothesis.
Scientific evidence is variable depending on the field but it is always collected by observational or experimental procedures.
In conclusion, Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical evidence) or the order of nucleotides (biological evidence).

The correct answer is A / an incision is longer than it is deep while a / an puncture is deeper than it is long.
Explanation
The word incision is a term generally referred to as a medical procedure in which a superficial cut is made on a surface of the skin, of different lengths with the help of a very sharp blade.
