Answer:
16) 6 electrons
17) 6 protons
18) 6 neutrons
19) 4 electrons
20) 6
Explanation:
There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.

Can you give me brainlyist if I awnser it plz
The correct option is: b. mitosis is not regulated in tumor cells. Cancer cells are malignant tumor cells and cancer is a disease of mitosis where the cell divides uncontrollably.
The tumor cells use mitosis to replicate and and cell cycle checkpoints are ignored so the mitosis is unregulated. So option c. tumor cells use meiosis to replicate is incorrect.
Tumor cells contain abnormal number of chromosomes so option d. is incorrect as it contains chromosomes.
Due to aneuploidy of tumor cells it cannot be specifically haploid or diploid so option a is incorrect.
Greetings,
I'm going to attempt to answer this; as far as I know, meiosis itself never involves chromosome replication.
Rather, replication occurs during the S-phase of interphase.
The cell then divides via meiosis to prevent further replication.
