The attractive forces that hold molecules together are electrostatic forces, when particles move fast enough, these forces can no longer keep particles together.
The forces that hold molecules together in a given state of matter are purely electrostatic forces. These forces keep the molecules together in a given state of matter.
Recall that the molecules of a substance are in constant random motion. When particles move fast enough, these forces can no longer keep particles together.

Can you plz explain what you mean by that . Maybe I can help if you give explanation.
Answer:
A sensory neuron.
Explanation:
The nervous system can be divided in two systems: the central nervous system and the peripheral nervous system. The central nervous system (CNS) is composed by the brain and the spinal cord. The peripheral nervous system (PNS) consists of the nerves and ganglia. Neurons are specialized cells that form the basic functional unit of the nervous system. There are three types of neurons: sensory, motor and interneurons. The sensory neurons are in charge of bringing signals into the CNS, and the motor neurons are in charge of carrying signals out of the CNS. The interneurons act as intermediaries, passing information between two neurons.
As the name implies, sensory neurons are activated by the senses, for example: sound, visible light, physical contact (heat and cold), chemical signals (smell and taste). The loss of sensation in one hand would be the result of a damaged sensory neuron.
Answer:
because they are bigger witch means more cells
Explanation:
they are bigger witch means more cells and the smaller animals have less cells and r always on the run from predators so they need to contently change to live
Answer:
Option C, The cell membrane allows water to enter and leave the cell.
Explanation:
Options for the question are –
A. The cell membrane is an impermeable barrier that prevents water from entering the cell.
B. The cell membrane allows solutes to enter the cell, which causes the cell to shrink.
C. The cell membrane allows water to enter and leave the cell.
D. The cell membrane removes solutes from the environment.
Solution -
The cell membrane is semi permeable to water and some other substances. Whenever there is a difference in concentration or volume on the two sides of the membrane, either the solute or the solvent starts moving till equilibrium is reached. In few cases, the flow continues uninterrupted thereby increasing the cell size to its maximum extent and hence bursting it.
Hence, option C is correct
