muscular system?
A. They are connected to bones.
B. They allow voluntary movement.
C. They allow us to move.
D. They are connected by gap junctions.
The one that is not true regarding muscular system is that they are connected by gap junction. The correct option is D.
What is gap junction?Gap junctions are specialized intercellular connections that connect a wide variety of animal cell types.
They connect the cytoplasm of two cells directly, allowing molecules, ions, and electrical impulses to pass through a regulated gate between cells.
Location includes that the gap junctions can be found in a variety of locations throughout the body.
This includes epithelia (surface coverings of the body), nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Their primary function is to coordinate the activity of neighboring cells.
Skeletal muscle cells lack gap junctions because they do not require them. Skeletal muscles are not made up of individual cells.
Thus, the correct option is D.

retinal.
carbohydrate.
When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.
