<span>The cpt codes that should be reported for this procedure are as follows: 64493-50, 64494-50. The reason for this is that these codes are for the injection of the lumbar. 64493 is the injection specifically, and 64494 is referencing L4. The -50 is added to show that the injection was done on both sides.</span>
Commensalism is defined as a relationship between two species where one has certain benefits from the relation and the other is unaffected. So, in this case, it is hard to determine what kind of relationship the gray wolf and human populations have because when people intervene to help protect a species they are officially unaffected, they do not lose or gain anything, but the gray wolf is one of the key species in their ecosystem, so protecting them is beneficial for the ecosystem, therefore can have numerous positive effects on human-environment too.
Answer:
1 . The stage on the first meiotic division when the homologous chromosomes move to opposite poles but the sister chromatids remain together
: b. Anaphase I
2 . The stage in the second meiotic division where sister chromatids migrate to opposite poles
: c. Anaphase II
3 . A structure on the chromosome that holds a pair of chromatids together during replication
: f. centromere
4 . A double-stranded chromosome following replication attached by a centromere
: d. chromatid
5 . A condition where non-sister chromatid of homologous chromosomes exchange genes
: e. crossing over
6 . The stage in the first meiotic division where the homologous chromosomes line up as a pair
: a. Metaphase I
7 . The stage in the second meiotic division where the chromatid pair lines up at the equator of the cell: g. Metaphase II
Explanation:
DNA replication occurs during the S phase of the interphase of the cell cycle. The replicated DNA molecules are accommodated in two sister chromatids of a chromosome that are held together by a centromere.
During prophase I, the chromatids of a homologous chromosome pair exchange a genetic segment. This process is called crossing over. It generates recombinant chromatids with new combinations of genes.
Metaphase I of meiosis I includes the alignment of homologous pairs of chromosomes at the cell's equator. This is followed by separation and movement of homologous chromosomes to the opposite poles of the cell during anaphase I.
Metaphase II of meiosis II includes the alignment of individual chromosomes, each with two sister chromatids, on the cell's equator. During anaphase II, splitting centromere separates the sister chromatids which then move to the opposite poles of the cell.
The building and or construction of proteins or polypeptides occurs at the small granule like organelle called the ribosome. These are small spherical structures either found on the rough endoplasmic reticulum or freely floating in the cytoplasm.
