charle [14.2K]
<h2>The correct answer is: e.</h2>

Explanation:

  • Decline in the global population of amphibians is due to multiple reasons which include:
  1. A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
  2. Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
  3. Infectious diseases often cause their death resulting their population to decline.
  4. Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.

An atom has an atomic number 17 and atomic mass number 35. How many neutrons are present in its nucleus?
Pie

Answer:

B. 18

Explanation:

An atom, which is the smallest indivisible particle of matter, further contains certain particles called SUB-ATOMIC PARTICLES namely: proton, neutron and electron. In a neutral/uncharged atom, the number of proton is equal to the number of electrons. The number of protons in an atom represent its ATOMIC NUMBER.

However, the sum of the proton number and neutron number gives the MASS NUMBER i.e. mass no. = proton no. + electron no.

Hence, according to this question which states that an atom has an atomic number of 17 and a mass number of 35. The neutron no. can be calculated as follows:

Neutron no. = mass no. - proton no.

Neutron no. = 35 - 17

Neutron no. = 18
