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.
Metals, non metals, and metalloids
Learning about the different body parts will help us better understand human life and health because it can make us care about others instead of just are selves and encourage us to do something about the health difficulties in life.
Answer
C. Tagging and wildlife tracking
Explanation
Wildlife tracking is a process employed by biologists and scientific researchers including conversational agencies to remotely the movements and migratory patterns of free-ranging wild animals using GPS and other sensors. The tracking and monitoring of these endangered species is vital because it helps in the conservation process. Through the monitoring of wildlife, agencies can keep track of animal potters, population demographics and habitat utilization.
