Answer: heres the 3 main functions.
Explanation:
membranes have three primary functions 1) they keep toxic substances out of the cell 2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment and 3) they separate vital but incompatible metabolic processes conducted within organelles.
False
Proteins are polymers of molecules called amino acids, some contain thousands. Lipids are formed when a glycerol molecule combines with compounds called fatty acids, therefore they are not polymers because they contain one molecule and are not macromolecules. Hope this helps! :)
Answer: B. Tendons; ligaments
Explanation: Tendons are white, inelastic and tough connective tissue that attach skeletal muscle to bone. Tendons attach muscles to structures such as the eyeball. Fibres in tendons are arranged as compact parallel bundles.
