In a DNA nucleotide, to which carbon on deoxyribose is the nitrogenous base attached?

The nitrogenous base is attached to 1' Carbon

Explanation:

DNA is made up of nucleotides and each nucleotide contains a deoxyribose sugar, a nitrogenous base, and a phosphate group. As the deoxyribose sugar contains five carbons the nitrogenous base is attached to the 1' carbon of the sugar.

There are four types of nitrogenous bases present in the DNA that are adenine, guanine, thymine, and cytosine. DNA is double-stranded and both the strand are present in antiparallel to each other so the hydrogen bond can be formed between the nitrogenous bases of two strands.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
