Answer:
What do you need help with?
Explanation:
Answer:
Water moves across a permeable barrier during osmosis to equalize the solute concentration on each side of the membrane. Nutrients, on the other hand, are absorbed across a barrier by a process known as diffusion
Explanation:
Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. Diffusion is the process by which atoms or molecules move from an area of high concentration to low concentration
The non-Hispanic black-white discrepancy has plateaued in recent years, and this is mostly because the prevalence of asthma among non-Hispanic black children has stopped rising.
From 2001 to 2009, there was an overall rise in the prevalence of childhood asthma; this was followed by a plateau and a drop in 2013. From 2001 to 2013, multivariate logistic regression revealed no change in prevalence among non-Hispanic white, Puerto Rican, and children living in the Northeast and West; increasing prevalence among children aged 10 to 17 who are poor and reside in the South; increasing then plateauing prevalence among non-Hispanic black children aged 5 to 9, and increasing then decreasing prevalence among Mexican children aged 0 to 4 years. Black-white gaps between non-Hispanic races ceased widening, while Puerto Rican children continued to have the highest incidence.
