Answer: Haploid number
In normal humans, sex cells contain the diploid number of chromosomes
Explanation;
Human somatic cells or body cells are diploid such that they contain two sets of 23 chromosomes which gives a total of 23 chromosomes. Examples of somatic cells in the body that are diploid include, epithelial cells, somatic cells, liver cells, blood cells, nerve cells, etc.
However, mature sex cells are haploid, which means they have one set of 23 chromosomes which means they have 23 chromosomes. Sex cells are the results of meiosis type of cell division in which a diploid cell divides to form four daughter cells that are haploid.
Answer:
Explanation:
Proteins and Nucleic Acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they're both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways. The major relationship between the two has to do with protein production -- DNA contains the information that a cell uses, with the help of RNA, to make protein.
Some blood cells responsible for the transportation of oxygen and other are there for rebuilding of tissues. Fights things the body doesn't recognize
