Answer:
The statement which states that cell has a dual existence of being the smallest fundamental unit of life and can also be a part of a multi cellular organism is TRUE.
Explanation:
According to cell theory, cells is the basic unit of life that can be found in all living organisms. There are two basic types of cells, these are prokaryotic and eukartyotic cells. Prokaryotic cells are very primitive in nature and are usually found in very small living organism. These organisms usually exist as unicellular organisms. This means, that a unicellular organism is made up of only one cell, which carry out all the activities that the organism needs to survive.
Multi cellular organisms on the other hands are made up of many cells, which work together to perform diverse functions. Thus, cells have the capacity to exist alone as a single cell and as part of group of cells.
Hi there!
I think bread turns moldy less quickly when it is kept in a refrigerator than when it is kept at room temperature because bacteria eats foods like bread and causes mold, and less bacteria grow in colder temperatures. Since less types of bacteria thrive in colder temperatures, it takes longer for less bacteria to create mold.
Hope this helps!
