The organ system that allows for movement of the organism as a whole and for internal movement of food through the digestive system, is the system. what is the blank answer?

Skeletal system

The organ system that allows for movement of the organism as a whole and for internal movement of food through the digestive system, is the skeletal system.

Explanation:

An organ system is a group of similar organs which work together to perform specific functions.

Examples of organ system in the body of animals include skeletal and digestive system.

The skeletal system consists of mainly of bones and cartilage, that helps in the following:

- movement

The body move by the aid of connected bones in the skeleton.

- Digestion

The body can carry out functions like contractions and relaxation of the oesophagus (peristalsis) to push chewed food into the stomach for digestion

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
