<span>Proteins are large biological molecules consisting of one or more chains of amino acids. Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job.
</span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.

Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>
Answer: False.
Explanation:
Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they perform different functions and are structured differently.
The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is <u>absorption and filtration.</u>
The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of <u>protecting against physical and chemical damage.</u>
Four chambered heart keeps oxygenated and deoxygenated blood separate and has double circulation while three chambered heart has a single circulation. Two chambered heart only has single atrium and single ventricle
Answer:
A. Specialized cells are made up of tissues
Explanation:
Cells make up tissues, tissues make up organs, organs make up organ systems and organ systems make up an organism.
All the other options are correct, but cells are not made up of tissues.
Hope this helps!
