the element nitrogen has an atomic number of 7 and an atomic mass of 14 how many protons, neutrons and electrons are in a atom o
Nat2105 [25]

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?

the size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantag
professor190 [17]

Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.

Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill. Any dangerous microbial agent, including bacteria, viruses, protozoa, fungi, and helminths, might be considered a pathogen.
