Answer:

What role do transcription factors play in gene structure and function?

Transcription factors are proteins that bind to the upstream regulatory elements of genes in the promoter and enhancer regions of DNA and stimulate or inhibit gene expression and protein synthesis. They play critical roles in embryogenesis and development

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative

Anon25 [30]

Answer:

$\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}$

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

$10^ {difference \ in \ pH}$

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

$10^5=100,000$

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>

Why is pcr used in the process of dna sequencing?

Vika [28.1K]

PCR allows for the analysis of DNA fragments through the comparison of the base pairs each molecule contains, which can then be used for genetic screening and the identification of individuals and DNA fragments

Siderophores are bacterial proteins that compete with the host's:______.a. antibodies. b. iron-transport proteins. c. white bloo

joja [24]

Answer:

The correct answer is iron-transport proteins

Explanation:

Siderophores are proteins produced by bacteria, and compete with the host's iron-transport proteins. They aim to bind and "hijack" the host's cell iron molecules for their own pathogenic cell processes
