Is it about a certain time period?
A pulse with unpredictable pattern is termed as an <em />irregularly irregular pulse. This kind of pulse coincides with an irregularly irregular heart rhythm seen in those with severe arrhythmias such as 3rd degree AV block. In contrast, there is a pulse that is irregular but has a predictable pattern termed as regularly irregular.
In the _PNS_, the cells responsible for insulating neurons with myelin are called _Schwann cells_, whereas in the _CNS_, the cells responsible for insulating neurons are called _Oligodendrocytes_.
False
Explanation:
The emission of radioactive particles by isotopes as they change into other elements overtime is not known as dendrochronology.
This phenomenon is known as radioactivity. The attendant emission of small particles of matter and electromagnetic ionizing radiation and considerable amount of energy is known as radioactivity.
- Dendrochronology is a method of dating that involves the use of tree rings to the exact years that they were formed.
- It is absolute different from radioactivity.

Answer:
The mutated cell will have 25 chromosomes.
Explanation:
Meiosis is a cell division process in sexual reproduction which involves two successive divisions of a cell having a diploid (2n) number of chromosomes into four daughter cells having a haploid (1n) number of chromosomes.
Meiosis consists of two successive nuclear divisions, meiosis I and meiosis II. Each division consists of these stages: prophase, metaphase, anaphase, and telophase.
Anaphase consists of anaphase I and II. During anaphase II, the centromeres linking the two pairs of chromosomes which are called chromatids separate, and the sister chromatids move toward the opposite poles of the cell and are now called chromosomes.
Therefore in the chimpanzee having 48 chromosomes, after underoing meiosis, each daughter cell will have 24 chromosomes. If there is a case of non-separation of one chromosome, the cell will have 1n + 1 chromosomes i.e. 24 + 1 = 25 chromosomes.
