The correct answer is: a. n+1, n+1, n-1, n-1
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.

The 85-year old female patient who presents to the emergency department (ed) with increasing shortness of breath, hypoxia, productive cough, and progressive weakness will be assessed and diagnosed by the nurse as someone who is probably having asthma. The mentioned symptoms are common with people who have asthma.
Answer:
As the beetles have a uniform distribution, at a carrying capacity of 14,600 beetles, there are about 128 beetles per hectare. Because 55 hectares are now unlivable, the carrying capacity would decrease by about 7,040 individuals (55 × 128).
Therefore, the carrying capacity of the ecosystem will be (old carrying capacity – decrease in carrying capacity) = (14,600 – 7,040) = 7,560 beetles.

Answer:
An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water.
