DNA is generally tightly packed into a structure called chromatin. It is double stranded and twisted into a structure called a double helix. In order to replicate, DNA must unwind. After unwinding, each side of DNA separates by unzipping down the middle, with the two unzipped strands serving as templates for creating new strands. At the end of replication, the two new segments of DNA each contain one old and one new strand.
Replication occurs at different rates in different types of cells. Some cells continuously divide and must constantly replicate their DNA. Other cells divide at a much slower rate and do not need to replicate their DNA as often. Some cells divide until the organ they make up reaches its normal size, and then they do not divide again.
DNA stands for deoxyribonucleic acid. Each strand of DNA is made up of a sugar, a phosphate and a nitrogenous base bonded together into a structure called a nucleotide. Many nucleotides bond together to form DNA.

Answer: anaphase
Explanation: Nondisjunction can occur during anaphase of mitosis, meiosis I, or meiosis II. During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell, pulled by microtubules

Answer:
The population would grow to 63,667 deer in a year, and the growth rate would decrease the following year.
Explanation:
Sika deer population : starting at 26000 in 2005
stabilized at 58000 between 2012 and 2014
rmax = 0.57
The population size of Sika deer be one year after the carrying capacity increased to 70000 as a result of deforestation
carrying capacity (k) = 70000
population size ( N ) = 58000
max growth(rmax) = 0.57
To determine the growth
dN/dt = rmax N [ (K-N) / K ] ---------- (1)
insert the given value into the formula above
dN / dt = 0.57 * 58000 [ 12000 / 70000 ]
= 33060 [12000 / 70000 ]
= 5667
The increase in population = 5667 + 58000 = 63667
