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.
The early hominid stages can be differentiated from one another based on the complexity of the tools used by these species. The tool evolved along with the evolution of the humans. The more the hominids evolved by more complex their tools became. The tools made by the earliest hominids were used to fish out the termites. These tool developed and became more widely used as the humans evolved.
Hence, the answer is 'by observing the complexity of the tools'.
B.) A food chain shows only a single pathway of energy.
Remember that food web are made out of lots of food chains combine. Food chain is only one pathway.
Answer:
According to the population growth graph, what can be determined about the population is that the carry capacity is around 0.4 million.
Explanation:
The graph shows the growth curve of a rabbit population, which is increasing progressively over the years until it flattens out in 2002, which is surely related to the carrying capacity of this population, established at around 0.4 million rabbits.
<u>
Carrying capacity is the maximum number of inhabitants that can be in a given place according to the space and resources available</u>. The population can increase as long as they have the necessary space and resources to support a certain number of inhabitants. When the population exceeds its carrying capacity, it experiences a decrease in growth.
<em>In the graph, the growth of the rabbit population decreased when it reached a number of inhabitants of 0.4 million.</em>

Not the plants but the soul could be made into mud in both past and present. In past, most houses(not in the US) but in many countries were made up of soil. But know in present, soil or even mud is used to put it in the concrete to make the building strong in many countries like India. Good luck:)
