Correct Answer: C) organisms compete for resources and better competitors survive and thrive

Explanation

The question is asking for the best explanation for the theories of natural selection. Natural selection is a process where organisms with certain traits are better adapted to their environment and are more likely to survive and reproduce. The organisms that are better adapted are more likely to pass on their genes to the next generation, while those that are less adapted are less likely to survive and reproduce. From the options given, the correct answer is option C: organisms compete for resources and better competitors survive and thrive. This means that in any environment, there are limited resources and organisms have to compete for them. Those that are better adapted or have better traits are more likely to get the resources they need to survive and reproduce. Over time, these traits become more common in the population, leading to evolution. Option A, which states that all organisms have equal capacity for survival in their habitats, is incorrect because different organisms have different traits that may make them more or less adapted to their environment. Option B, which states that organisms have varying capacities for survival in their habitats, is partially correct, but it fails to mention the important role of competition in natural selection. Option D, which states that habitats allow only organisms that will not have to compete for survival, is also incorrect because all organisms have to compete for resources to some extent. It is important to note that natural selection is just one of the mechanisms of evolution, and that there are other factors such as genetic drift and gene flow that also play a role in shaping populations over time.

Correct Answer: D. baptism

Correct Answer: B) CH₂

Explanation

Alkanes are a class of organic compounds consisting of carbon and hydrogen atoms, and they belong to a homologous series. A homologous series is a group of compounds that have the same general formula, similar chemical properties, and show a gradual change in physical properties.

In the case of alkanes, the general formula is C_nH_2n+2. Consecutive members of an alkane homologous series differ by one carbon atom and two hydrogen atoms, which can be represented as CH₂. This is because, as you go down the series, each alkane has one more carbon and two more hydrogen atoms than the previous one.

For example, let's consider three consecutive alkanes: methane (CH₄), ethane (C₂H₆), and propane (C₃H₈). As we move from methane to ethane, we add one carbon atom and two hydrogen atoms (CH₂). The same difference applies when we move from ethane to propane. This pattern continues throughout the alkane series.

Therefore, the correct answer isOption B: CH₂.
