Explain whether or not you expect the chaparral biome to be sensitive to the loss of a single species.
aleksley [76]

Answer:

See the answer below

Explanation:

The chaparral biome is a temperate biome with a characteristic high temperature and dryness during summer and mild rainy winters and springs. The biome can be found in relatively small amounts in the major continents of the world with its rich plant and animal diversity who have successfully adapted to the conditions of the biome.

Due to the high biodiversity of the chaparral biome, <u>one would expect it to be resilient to the loss of a single species.</u> <em>The more the biodiversity of a biome or community, the more resilient such biome or community would be to the loss of species and lower the biodiversity, the more sensitive the community would be to the loss of species. </em>

An atom has an 16 protons, 18 neutrons, and 13 electrons. What are its atomic number, atomic mass, and net charge?
Lemur [1.5K]

Answer:

Atomic number = 16, Atomic mass = 34, Net charge= +3

Explanation:

i) Atomic number = Proton number = 16

ii) Atomic mass = Proton number + Neutron number

                         = 16 + 18 = 34

iii) Net charge= Proton number = Electron number (when element is in ground state or unreacted state)

But, proton number (16) is not the same as electron number (13), this means the element has lost 3 electrons

Thereore, the net charge is = 16-13

                                              = +3
