Ben observes how quickly some dry wood is burning in a campfire. which term best relates to ben’s observation?
reaction rate
activation energy
collision theory
spontaneous reaction

reaction rate - first choice

Option (a) is the correct answer.

Explanation:

Rate of reaction is defined as the rate consumed by the reactants to result in the formation of products.

For example, when Ben observes how quickly some dry wood is burning in a campfire then it basically depicts the rate of combustion of wood.

Activation energy is the minimum amount of energy required by reactant molecules to undergo a chemical reaction.

Thus, we can conclude that in the given situation reaction rate best relates to Ben’s observation.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
