Explanation:

A number that comes before a molecule such as 5H2O or 6NaCl refers to how many of that molecule there are. A subscript added to an element in a molecule refers to how many atoms of that element are in the molecule.

masya89 [10]
Phosphates generally come from fertilizer,  erosion of phosphate-containing rocks.   they are fertilizers, so they tend to strongly encourage growth, particularly of bacteria and algae. This can  harm ecologies, particularly in water, and particularly where there isn't a very robust growth medium already, e.g. in cold or desert waters.<span>This impacts the environment and our health because we use tap water for cooking, bathing, brushing teeth, and etc. and these water by be contaminated because of all of this pollution going around</span>

At a fair or circus, some performers and clowns take long balloons and fold them into animals and objects as toys for children.
mixer [17]

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.

Answer:

4. Variations that help with survival will be passed on to future generations and will rapidly change the whole population.

Explanation:

Variations that help with survival MAY be passed on to future generations, depending on how much pressure that variation relieves. Change may not be rapid, depending on how fecund the species is. Also, it will not change the whole population, only future offspring. The current offspring won't all have the new variation.
