answer: the circulatory system helps transfer oxygen and also delivers nutrient molecules
Find the lengths AB, BC and AC.length AB= √((2--3)²+(1-6)²) = √(5²+(-5)²) = √50length BC = √((5-1)²+(9-2)²) = √(4²+7²) = √65length AC = √((9--3)²+(5-6)²) = √(12²+1²) = √145
From the lengths of this triangle it can be seen that no side is equal to the other and also it is not a right triangle.
So, triangle ABC is a scalene.
<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.
</span><span>
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 - Many Types Such as
Golgi Body
Mitochondria
Nucleus
Chloroplast
Endoplasmic Reticulum
Reasoning - These are specialize Organelle which function in each part of doing their duty require the layers to keep it separate in maintaining certain materials they receive within the cell.
