A protein spans the nuclear membrane, with a small extranuclear domain, a substantial segment crossing the nuclear membrane, and a domain within the nucleus. It is.(a) a peripheral membrane protein(b) an integral membrane protein(c) a lipid-anchored protein(d) impossible

(B) an integral membrane protein

Explanation:

Integral membrane proteins are deeply embedded in the nuclear membrane. While some integral extend only into the membrane matrix, Some integral proteins span the whole nuclear membrane and are called trans-membrane proteins because the span from the extracellular nuclear membrane to the innercellular membrane. The serve as transport channels.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

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.
