Blank are the proteins tgat dna is wound around to form chromosomes

Histones are the proteins that DNA is wound around to form chromosomes.

Histones are proteins that are alkaline in nature, found inside the  nucleus of eukaryotic cells. The main function of histones is that they act as spools around which DNA is wound so it can fit inside the cell nucleus.

The length of DNA is 6 feet. When wound around  histones, this shortens to 0.09 millimeters. There are five types of histones designated or simply known as H1, H2, H3, H4 and H5.

a. the production of carbon dioxide through the process of photosynthesis

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
