Answer:
5. All magnesium atoms have the same number of neutrons
Explanation:
Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).
The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they vary in the mass number of the atom (M).
The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.
Based on this information we can know how many neutrons each isotope has
24 Mg = 12 protones + 12 neutrons
25Mg = 12 protones + 13 neutrons
26Mg = 12 protones + 14 neutrons
In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>
Species is a group of living organisms consisting of similar individuals capable of exchanging genes.

Answer:

Explanation:
To explain the last sentence, what I mean by that is the sudden decrease in air pollution in just a few weeks is what would have typically taken multiple years to do. Due to less drivers, factories shutting down, and more, less toxic and infirm mental hazardous chemicals were released into the atmosphere in an extremely short amount of time. However, nowdays, it is almost back to where is was before the pandemic.
Answer: the answer is tuberculosis
Explanation:
Answer:
Given merely 40 butterflies were marked, assumed that there were multiple captures of both marked and unmarked butterflies, that the butterflies caught in traps were on the loose to be caught again. There are two mathematical solutions for this, both yielding the same answer which is 100.
• First, to each marked butterfly was taken twice (40 marked X2 = 80 captured) then of the unmarked butterflies the 120 captured must relate to 60 actual butterflies. In which 40 + 60 = 100.
• Secondly, by means of ratios in which 80/200 = 40/X. In this case X also = 100 that will result to the estimated size of the population of wilson park is 100.
