The R group is what allows amino acids to form macromolecules with different properties. every amino acid has the same basic structure, the only difference is what the R group is made up of. The similarities allow the amino acids to form a chain while the differences allows them to have different functions. Hope this helped!
A wind instrument is a musical instrument that contains some type of resonator (usually a tube), in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece.
Answer:
Cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, coccyx.
Explanation:
Vertebral column or spine is made of a total of 26 vertebrae in adults. Starting from the upper part, it has 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, one sacrum, and one coccyx.
The coccyx is made of four fused coccygeal vertebrae. Likewise, the sacrum consists of five sacral vertebrae that are fused during development.
The correct answer is by facilitated diffusion.
The procedure of continuous passive transport of ions or molecules through a semi-permeable membrane with the help of particular transmembrane integral proteins is known as facilitated or passive-mediated transport or facilitated diffusion.
It is a modification of osmosis incorporating a proteinaceous channel via which an extracellular solute can enter a cell in the absence of energy.
