Neurotransmitters are broken down by enzymes in order to avoid over-stimulation of a neuron and to allow for the transmission of impulse another impulse by the neurons.
<h3>What are neurotransmitters?</h3>
Neurotransmitters are chemical substances which are released at neuronal ends and which help transmit sction potential from one neuron to another.
After the transmission of impulse between the neurons, neurotransmitters ate broken down by enzymes.

Answer:
No, you need both mass and volume to determine its desity to see if it can float.
Explanation:
Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
Answer:
Light microscopes can only magnify up to 2000 times the original size. It is difficult to enhance the contrast between cells and their surroundings to see cell structure and movement with a light microscope.

AND PLZ ANSWER MY Q!
Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
<h3>WHAT IS MEIOSIS?</h3>
Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.
Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.
Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.
Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
