Answer:

Electron

Explanation:

According to the Bohr model, an atom contains three sub-atomic particles. These particles are electrons, protons and neutrons. Electrons are negatively charged, protons are positively charged and neutrons are neutral particles. Protons and neutrons are present in the nucleus. They are called nucleons. Electrons are present outside the nucleus.

Most of an atom's mass is in the nucleus because the atomic mass of the proton is 1.0073 AU, the atomic mass of the neutron is 1.0078 AU. The atomic mass of the electron is 0.00054858 AU.

Thus, the sub-atomic particle the electron has least atomic mass.

Using the 10 percent rule, explain why there is typically smaller populations of quaternary consumers compared to primary consum
grandymaker [24]

Answer:

As we know 10% law is transfer of energy from higher trophic level to lower trophic level. So as the energy are transfer from one organism to another there is a loss of energy as that energy are utilised by the oragnism and only 10% of the total energy is transferred to the second consumer.

Explanation:

Quetinary consumer are at the higher position in the food chain so they do not get enough energy from prey they have to feed on several organism for the enegy. And also they are at the top of the food chain so they are not eaten by other animal, their life span are also more than primary consumer.

In other hand primary consumer get enough energy but they are prey for other higher tropic level.

Primary and secondary consumer are maintend in such a way by the nature thats make a ecological balance of the habitant.

Answer:

The correct option is 3

Explanation:

An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.

The third option can be easily answered using the "requirements" above.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.
