1. Which of the following explains how natural selection leads to evolution?

Conditions in the environment reduce competition for resources within a species
Helpful variations accumulate among surviving members of the species***
Overproduction provides food for stronger members of the species
Environmental changes favor weaker members of the species

WRONG, not even the question of the quick check.

The correct explanation is that helpful variations accumulate among surviving members of the species. Natural selection is a process by which individuals with advantageous traits that help them survive and reproduce are more likely to pass on those traits to the next generation. Over time, these helpful variations accumulate within the population, leading to evolution.

The correct answer is: Helpful variations accumulate among surviving members of the species.

Natural selection is the process by which certain traits or characteristics become more or less common in a population over time. It occurs because not all individuals in a population are the same, and some may possess traits that give them a better chance of surviving and reproducing in a particular environment.

The process begins with variation within a species. Individuals of a species differ from one another in terms of their traits or characteristics, such as body size, coloration, or behavior. Some of these variations are heritable, meaning they can be passed on to future generations.

When a population is faced with environmental challenges, such as limited resources or predators, some individuals may be better adapted to these conditions due to their specific traits. They have a higher probability of surviving and reproducing compared to individuals with less favorable traits.

Over time, as these advantageous traits are passed on to offspring, they become more common in the population. This leads to evolution, as the overall genetic makeup of the population shifts towards these advantageous traits.

So, in the given options, the explanation that best describes how natural selection leads to evolution is that helpful variations accumulate among surviving members of the species. This is because advantageous traits accumulate over time in a population as a result of natural selection, leading to the evolution of that species.
