Answer: Diploid; 2n
Explanation:
In many species, there are two representatives of each chromosome. In such species, the characteristic number of chromosomes is called the DIPLOID number. It is usually symbolized as 2n.
The two basic sets of chromosomes is called Homologous chromosomes, being two, it is called DIPLOID NUMBER (if one, it is Haploid number) and symbolized by 2n.
Species like man expresses the diploid number, so is a diploid specie
Cells are combined in a structure called tissue wich have the same properties like the cells wich are formed by.
Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
Answer:
the answer is all of the above
