When a pollutant is removed from the air by a natural process, it ends up somewhere else.
Yes, the different frequencies of evolutionary change could affect allele frequency in a population.
<h3>What are the agents of evolutionary change? </h3>
All populations are usual in a constant state of evolution. This means that all the species are continuously changing their genetic makeup over different generations. These changes can be subtle or they can be spontaneous.
If a population is not evolving, it is said to be in Hardy - Weinberg state. In this state, the allele frequency and the genetic makeup of the population will remain the same across generations.
The agents of evolutionary change defy the Hardy - Weinberg state. These are mutation, gene flow, non-random mating, natural selection and genetic drift.

Dichotomous Keys are used to find out what type of animal,plant,fungi,prokaryote,eukaryote,or bacteria an organism is. A branching diagram is used to find what domain,kingdom,phylum,class,order,family,genus,species an organism belongs in.
Melting of ice and island decreasing in level
Answer:
4 Fe + 3 O₂ → 2 Fe₂O₃
Explanation:
Let's start with the oxygen.
Reactants - 2
Products - 3
What number do 2 and 3 have in common? 6.
Put a 3 in the reactants and a 2 in the products to balance the oxygen.
Fe + 3 O₂ → 2 Fe₂O₃
Now let's look at the iron.
Reactants - 1
Products - 4
Put a 4 in the reactants to balance the iron.
4 Fe + 3 O₂ → 2 Fe₂O₃
The equation is balanced. Hope that helps.
