Answer:
of diffusion
Explanation:
Particles travel along a concentration gradient without requiring energy. This indicates they transition from an area of high concentration to one of low concentration. This process takes place across a semi-permeable membrane, such as the cell membrane, via simple diffusion.
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 sensory input arrives at the CNS, the spinal cord and the brain interpret what it means precisely.... Everything except for the CNS is referred to as the peripheral nervous system. The PNS consists of the nerves that extend from the brain and spinal cord to various regions of the body.
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.
