Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
the answer is their cells grow more rapidly than the surroundings cells
Water or other molecules move down their concentration gradient without any energy.........
difference - simple diffusion uses help of transporting protein in the membrane whereas osmosis uses no help.
C is your answer so pick c
Answer:
78701
Explanation:
The nuclear imaging examination is done to accompany the blood as it transported to the kidneys in order to reveal whatsoever blockage and to assess the level of which the kidneys perform filtration. The case study does not pinpoint to the capability of the kidneys tubes and ducts.
In the CPT® Index view for Nuclear Medicine/Diagnostic/Vascular Flow leads us to code range 78701-78709. Since mainly vascular flow was undertaken, we can infer that code 78701 is the right code to report.
