A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.
Proteins are the macromolecules made of hundreds of amino acids. Proteins are most varied class of biological molecules and show the greatest variety of structures. Many have detailed three-dimensional folding patterns that result in a compact form, but others do not fold up at all and they are in random conformations. The function of proteins depends on their structure.
The secondary structure of protein fold together to form the 3D arrangement of a polypeptide chain that results into Tertiary structure which is a functional protein.
<span>Centrosomes are made of from arrangement of two barrel-shaped clusters of microtubules, called “centrioles,” and a complex of proteins that help additional microtubules to form.</span>
ANSWER: the 3 different life spans found in plants are annuals, biennials, and perennials
Organelles that are involved in the formation and transport of proteins out of the cell which include:
•Ribosomes- synthesized proteins
•Rough endoplasmic reticulum-transfers proteins from ribosomes
•Golgi apparatus-temporarily stores, modifies and packages protein out of the cell
