Answer:
1) The stage of mitosis in which the chromosomes move to opposite ends of the cell. >>>> Anaphase
2) forms the ends of the spindle fibers in the cell during mitosis.
>>>>>Centriole.
3) part of a chromosome that attaches to the spindle apparatus during mitosis or meiosis. >>>>>Centromere
4) a structure that forms across the middle of a higher plant cell in telophase; the beginning of a new cell wall which divides the two daughter cells from one another to finish mitosis. >>>>>Cell plate.
5) material in the cell nucleus that carries hereditary information; made up of DNA and various kinds of protein. >>>>>Chromatin.
<span>DNA polymerase is the enzyme that connects new nucleotides and proofreads them into separate DNA strands.
This process is part of DNA replication. A cell's DNA is replicated before a cell divides. The two strands of a DNA molecule have complementary base pairs. Each strand in the pair consists of a nucleotide sequence which is able to provide the information to duplicate itself. Before the duplication occurs, the length of the DNA that is about to be copied must be unwound and the two strands must be separated. This is done by breaking the weak hydrogen bonds that link the pairs together. They must then be kept apart from each other to expose the bases so that the new nucleotide partners can bond to them. DNA polymerase is the enzyme that moves along the exposed DNA strand and joins the new nucleotides to manufacture a new DNA strand that is a duplicate of the original</span><span>

Bacteria reproduces exponentially so like at first you’d have one, then 2, then 4, then 16... (because each bacteria splits into 2) and eventually a few hours later you’ll have millions
The synaptic pruning during childhood results in a reduction in density of nerve cells, thus increasing the brain's efficiency.
<span>Synaptic pruning, which can include both axon and dendrite pruning, is the process of synapse elimination that occurs usually in early childhood. It is thought that this is the brain’s way of removing connections in the brain that are no longer needed and a way of maintaining more efficient brain function.</span>
