White fat functions in thermal insulation and brown fat uses lipid to generate heat.

False:On mRNA, three sequential nucleotides are referred to as a codon. Codons are read during translation to direct the incorporation of specific amino acids into a growing polypeptide chain. A triplet refers to three sequential bases on DNA, which together code for one amino acid. This terminology applies specifically to DNA rather than mRNA.

A. collagen, elastin, and reticular fibers:These are the main types of fibers found in connective tissue, providing strength, elasticity, and support, but they do not represent all three main components.

B. ground substance, fibers, and cells:Connective tissue is composed of cells (such as fibroblasts, macrophages, and adipocytes), fibers (collagen, elastin, reticular), and ground substance (a gel-like material that fills the extracellular space). These three components work together to provide support, strength, and a medium for nutrient and waste exchange.

C. alveoli, fibrous capsule, and secretory cells:These structures are specific to glands or organs like the lungs, not general components of connective tissue.

D. fibroblasts, chondroblasts, and osteoblasts:These are specific types of connective tissue cells responsible for producing matrix in different connective tissues, but they do not account for fibers and ground substance, so they are not the three main components
