Consider the following scenario:
In a muddy lake environment, some fish have brown scales. Most fish, however, have silver scales. Predators have a harder time seeing the fish with brown scales.

The accurate statement about variations is: "Organisms with variations that give an advantage are more likely to survive."
To determine the correct answer, we can analyze each statement:
1. "Organisms with variations are less likely to pass these variations to their offspring." - This statement is incorrect. Variations can be passed on to offspring through genetic inheritance.
2. "In all cases, variations affect how likely it is that an organism reproduces." - This statement is partially correct. Variations can influence an organism's ability to reproduce, but it is not true in all cases, as some variations may have no impact on reproductive success.
3. "In all cases, variations become more common in a population." - This statement is incorrect. Variations can become more or less common in a population depending on factors such as natural selection, genetic drift, and gene flow.
4. "Organisms with variations that give an advantage are more likely to survive." - This statement is accurate. Variations that provide an advantage in a particular environment increase an organism's chances of survival and reproduction, thereby increasing the frequency of these advantageous variations in the population over generations. This concept is central to the theory of natural selection.
