salantis [7]3 years ago

Answer:

In the first diagram the weakened pathogen (weaker version of the disease) is inserted into the bloodstream.

In the second diagram the antibodies kill the weakened pathogen. When the immune systems encounters a new disease it "remembers it".

This is why in the third diagram, when the "real" pathogen enters the bloodstream the immune system can effectively kill the disease. As the immune system "remembers" how to defeat the weakened version it can more effectively kill the "real" version.

Celery stalks that are immersed in fresh water for several hours become stiff. Similar stalks left in a 0.15 M salt solution bec
mixer [17]

Answer:

From this it can be deduced that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks.

Explanation:

When submerged in water, the celery stalks become stiff and hard, this shows that water moves within the stalk, thus, water is hypotonic in comparison to the celery stalk. Therefore, water moves from the region of higher concentration to the region of lower concentration.  

When the same celery stalk is administered into the 0.15 M solution it turns soft, which shows that water from the celery stalk moves out. Thus, the salt solution is hypertonic in comparison to the celery stalk. Therefore, freshwater is hypertonic and the solution of salt is hypertonic to the celery stalk cells.
