Phenolphthalein is a weak acid and is colorless in solution. It is generally used to find out the endpoint of titration. As the An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red it indicates the pH of the solution is 8.0 or above.
<h3>What is phenol red?</h3>
Phenol red is an indicator whose color can exhibit a gradual transition from color yellow to red.
Phenol red is actually a water-soluble dye as is used as a pH indicator, changing from yellow to red over pH 6.6 to 8.0.
Thus, it can be concluded that the pH of the given unknown solution is in range 8.0 or above.

Answer:
Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the translational apparatus.
Explanation:
Answer:
Sorry, I don't know the answer, but I do know this:
Explanation:
Cold-blooded animals have resistance against microorganisms, and when they are infected, they reduce body temperature as a defense mechanism. Warm-blooded animals have a much stronger immune system to defend against such microorganisms. They gain energy in the form of heat to regulate body temperature for survival.
I hope this helps.
