Answer:
Limited
Explanation:
For competition to exist within a population or between population, shared or common resources that organisms holds very important must be very limited and scared.
Competition is a struggle between organisms for limited resources in the ecosystem.
- It is an interaction between organisms in which one of them is harmed.
- Competition originates from limited supply of shared or mutual resources among organisms.
- When competition is between organisms from different population, it is called an interspecific competition.
- Competition between organisms within the same population, i.e of the same species is intraspecific competition.
Answer:
a, b, c, d
Explanation:
Rutherford’ atomic model is based on the gold foil experiment. In this experiment, beam of alpha rays was bombarded on thin gold foil. He observed that:
Most of the alpha particles passed through thin foil without any deflection.
Few alpha particles deflected by an angle of 90o.
Based on observation, Rutherford concluded that majority of the space inside the atom is empty.
He explained defection of few alpha particles by assuming that most of the mass is concentrated at the nucleus and positively charged.
Therefore, among given, the correct statements are:
The atom contains a positively charged nucleus.
Positive charge is condensed in one location within the atom.
The majority of the space inside the atom is empty space
The mass of an atom is concentrated at the nucleus
Therefore, the correct options are:
a, b, c, d
A physical change is like freezing water and it turns into Ice.
