Answer:
a)Difference in physical state observed:
The difference between the two carrots is that the carrot in the plain water appears bigger or slightly swollen while the carrot in the salt water appears smaller and has shrank in length and slightly in width.
b)Process involved that has caused the changes:
The process that has taken place is osmosis.
c)Why has the process occured:
The process occurs due to the semi-permeable membrane of the cells of carrots that allow water either in or out of the cells.
In the plain water, the process that takes place is endosmosis where the cells of the carrot draw in water and hence the carrot increases in mass. The carrot in the salt water, on the other hand, experiences exosmosis, where water is drawn from the carrot's cells and the carrot becomes dehydrated and shrinks in length and width.
d) Beaker 1 : Water
Beaker 2 : Sugar Solution
e) example of endosmosis is absorption of capillary water from the soil by the root.
another example of endosmosis is is entrance of water in the xylem vessel from the soil by the root.
True.
Believe me, I am 100% sure, hope this help!
Natural resources are the resources that occur naturally like water, sunlight, wind etc. Organisms including humans use natural resources in many ways. Humans use water for drinking, agriculture, washing clothes etc. Many aquatic organisms use water as their habitat, for example fish. Plants use sunlight for synthesis of food. We use wind for inhaling oxygen. Apart from that, we also use sunlight and wind to generate electricity.
This is an indispensable process that allows cells to divide for a living organism to grow or reproduce each new cell needs DNA copy which serves as instructions on how to function as a cell.
