The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.
Generally, air can be trapped in a balloon by sealing its neck tightly.
Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.
A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.
In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.

Explanation:
The answer is c in my understanding
Vacuole can occupy up to 90% of the cell volume and can exert turgor pressure against the cell membrane when it acquires water.
In biology, a vacuole is a membrane-bound space found in the cytoplasm of a plant cell.
These are large size compartments that can occupy up to 90% volume of water.
In fully grown plants, vacuoles play a very significant role as they help out in plant growth, storing water, disposing of waste materials, and protecting cells against external barriers.
In sum, vacuoles are generally small in size but important cell organelles that are present in bacteria, fungi, and protozoa.

The provided question is incomplete as it lack the correct options to answer the question correctly however the correct options are as follows:
a) Environmental factors have no role in the occurrence of either type of diabetes.
b) Type II diabetes appears to be caused by a single, unidentified gene.
c) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.
d) Genetic factors have little or no role in the occurrence of Type I diabetes.
e) Type II diabetes is primarily determined by non-genetic factors.
Answer:
The correct answer option C.
Explanation:
Genetic factors influence the development of the type I and type II diabetes in monozygotic twins in the study by the concordance rates of 30 -50% and 80%. In both type of diabetes the genetic influences also present but comparatively low in dizygotic.
In this study the role of genetic influences are mentioned directly where is no information about environmental influences are present. It also suggests that the influences in Type II is higher than the type II diabetes.
Thus, the correct answer is option C.
