Answer:
because earth is so many people around the world
Water is the main constituent on the earth surface. It is important for all living beings to survive. It is a transparent, odourless, colourless chemical substance. Water has vital role in atmosphere. It undergoes several cycles. In water cycle, water from rivers, lakes and streams enters the atmosphere through Evaporation. In evaporation the element or the compound in it's liquid state changes to gaseous state below the temperature at which the it boils. This is due to the high temperature. Due to high temperature the water from different water bodies enters the atmosphere in the form of vapours. In the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. Transpiration is a process by which the moisture is transferred from roots to the outside of the leaf whic
Therefore, In water cycle, water from rivers, lakes and streams enters the atmosphere through vaporisation. in the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. In nitrogen cycle, the water as well as dead organism moves nitrogen from the atmosphere into the soil.
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.
That is an example of thermal energy which was passed on by conduction.
