Phycobiliproteins are a. found in purple sulfur bacteria. b. found in cyanobacteria. c. used to gather wavelengths of light that are not well absorbed by chlorophyll. d. are used to reduce hydrogen sulfide. e. found in cyanobacteria and used to gather wavelengths of light that are not well absorbed by chlorophyll.

The correct answer is option E.

Explanation:

The deep-colored, water-soluble proteins, which are mainly found in Rhodophyta and cyanobacteria are known as phycobiliproteins. They captivate the light energy and then pass it to the chlorophyll at the time of photosynthesis.  

They are comprised of proteins and are covalently attached through cysteine amino acid chromophores known as phycobilins. Thus, the correct answer is option E.  

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
