Answer:
b. Some carbon dioxide will move from chamber A to chamber B.
Explanation:
The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
Since, the options are not given the question is incomplete. The complete question is as follows:
The laboratory analysis conducted on a child with chronic nasal drainage reveals an elevated number of eosinophils on a white blood cell differential. Based on this finding, which is most likely the cause of the nasal drainage?
a. Bacterial infection
b. Viral infection
c. Chronic inflammation
d. Allergies
Answer: d. Allergies
Explanation:
During the allergy the eosinophils are recruited at the site and these are produced in large number by the bone marrow cells. The allergic conditions may developed during the sinus infections where chronic nasal drainage occurs in order to expel out the pathogen from the body. The parasitic diseases and allergic reactions will result in the excess production of the eosinophils.
The given situation is a result of the allergic reaction which brought about large increase in the number of eosinophils.
Explanation:
Geological features at divergent boundaries are:
On land:
- Rift valleys
- Geothermal vents
On seafloor:
A divergent boundary is a constructive margin where two plates moves away from each other. Divergence allows for new magma to upwell to the surface.
Evidence of divergence is seen in the ocean as the mid-oceanic ridge and seamounts.
On land i.e within the continent: rift valley systems in East Africa and Geothermal vents in Iceland are popular features.
