The correct answer is d. 8p+; 9n; 10e−
Oxygen exists in three isotopes ¹⁶O, ¹⁷O and ¹⁸O. The atomic number of oxygen is 8. It means its nuclei has 8 protons. The given is oxide⁻² anion. This means it has gained 2 electrons. Thus, oxide anion have 8 protons and 10 (8+2) electrons. The number of neutrons depends on the isotope, in this question mass number is given¹⁷O. The mass number is the sum of the protons and neutrons in the nucleus. Hence, number of neutrons oxide anion will be 17-8 = 9 neutrons.
Answer:
The answer is higher.
Explanation:
ADH which stands for Antidiruetic Hormone is a hormone procuded by the hypothalamus in our brains and helps our kidneys save the water in the body in certain situations.
The example given in the question states that the person has not been drinking water during the three mile run, which indicates a lack of water and also the loss of water by means of sweating during the running process. These would result in a much higher level of ADH in the bloodstream due to the body trying to hold onto the liquid that remains in the body to cover for the loss and lack of water.
I hope this answer helps.
Answer:
Eukarya
Explanation:
According to the given information, the observed cells have nuclei and chloroplasts. The presence of a well-defined nucleus and other membrane-bound organelles such as chloroplasts is a feature of eukaryotic cells. All the eukaryotic organisms are assigned to the Domain Eukarya. Therefore, the observed cells belong to the domain Eukarya. Due to the presence of chloroplasts in them, these cells may belong to the kingdom Plantae of domain Eukarya. Domains Archaea and Bacteria include prokaryotic organisms.
