Answer:
B
Explanation:
A peptide is a short chain of amino acids. ... Meanwhile, proteins are long molecules made up of multiple peptide subunits, and are also known as polypeptides. Proteins can be digested by enzymes (other proteins) into short peptide fragments. Among cells, peptides can perform biological functions.
The main reason why ssuch standardized tests such as the Quality Ratnig and Improvement System (QRIS) is being used is because it helps in improving and standardizing the quality of care in all facilities in the state. Through this, people can leave feedback and help improve and standardize healthcare overall.
1. Pass through the cochlea, are transformed into nerve impulses and sent to the brain - sound waves
2. Forms in your outer ear and is meant to protect your ear from dirt and infection – cerumen
3. Receives sounds and sends them through the auditory canal to the eardrum - outer ear
4. A thin membrane that transmits sound waves into the middle ear – eardrum
5. Where the cochlea is - inner ear
6. A snail-shaped organ lined with hair cells. – cochlea
7. Inside, small bones transmit sound waves from the eardrum to the inner ear - middle ear
8. Destroyed by extended exposure to loud noise - hair cells
Explanation:
During hearing, sound waves are received by the outer ear and pass it on to the ear drum through the external auditory canal.
The sound waves upon hitting the eardrum makes it to vibrate and the vibrations are passed on the ossicles of the middle ear. The sound waves are amplified by the ossicles and passes to the inner ear where it reaches the cochlea.
The sensory hair cells in the basilar membranes of the inner ear move the sound wave and also help to create electric signal which is received by the auditory nerves.
These signals are received by the brain where the sound waves are processed.
Answer:
D. Yes, two hydrogen bonds could form between thymine and cytosine.
Explanation:
A hydrogen bond (often informally abbreviated H -bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group, particularly the second-row elements nitrogen (N), oxygen (O), or fluorine (F)—the hydrogen bond donor (Dn)—and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac).
The formation of stable hydrogen bonds depends on the distance between two strands, the size of the bases and geometry of each base. Stable pairings occur between guanine and cytosine and between adenine and thymine (or adenine and uracil in RNA).
One hydrogen bond could form between the C4 carbonyl group on thymine (a hydrogen bond acceptor) and the C4 amino group on cytosine (a hydrogen bond donor). Another hydrogen bond could form between N3 of thymine (a hydrogen bond donor) and the N3 of cytosine (a hydrogen bond acceptor). Note that the C2 carbonyl groups found on both bases are both hydrogen bond acceptors and therefore a hydrogen bond cannot be formed between them.
