Answer:
Eardrum→Ossicles→Oval window→Endolymph→Perilymph
Explanation:
The ear functions as the organ responsible for hearing and preserving balance in mammals. In these creatures, it is typically categorized into three sections: the outer ear, the middle ear, and the inner ear. The outer ear is made up of the pinna as well as the ear canal. The middle ear encompasses the lymphatic space and the trio of ossicles. The inner ear is located within the bony labyrinth and contains vital components linked to various senses: the semicircular canals which assist with balance and eye coordination during movement, the utricle and saccule which help maintain balance when still, and the cochlea that facilitates hearing.
Answer:
22 autosomes along with an X or Y chromosome
Explanation:
Humans possess a total of 46 chromosomes, with 23 inherited from the mother and 23 from the father. The father's contribution includes an X and a Y chromosome, while the mother contributes two X chromosomes. Each parent passes down 22 chromosomes, while the remaining chromosome, the 23rd, corresponds to sex characteristics. Autosomes represent all chromosomes that do not determine sex, thus each parent provides 22 autosomes. Therefore, from the father, 22 autosomes and one X or Y chromosome are received.
When stimulated, the stomach's environment is characterized as acidic. It secretes protease enzymes and hydrochloric acid to assist digestion. The hydrochloric acid keeps the pH low, enabling protease enzymes to effectively break down proteins. Following digestion, the stomach returns to its normal pH level. Therefore, acid secretion coincides with food presence to support proper digestion.
