This statement is true. Neurons are not connected but they pass signals to each other through the synapse. The dendrites of the neurons are covered with synapses that allows them to send signals towards the next axon ahead of them.
During mitosis, chromosomes are moved and separated through the use of spindles composed of microtubule structures.
Explanation:
Throughout mitosis, the chromosomes are initial replicated (copied) and so distributed into a pair of new "daughter" cells. They're replicated throughout the S section of interphase, and within the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at that purpose the cell divides. The strand of chromosomes split just like the cell throughout the cellular division. They split in half.
Amino acids are the building blocks of proteins
A mutation can either be passed down as a hereditary trait, but most mutations of the gene can be triggered by something such as radiation from the sun, or if an error is made in cell division as DNA copies itself
