WHAT NATURAL SELECTION CAN ONLY ACT ON WHICH TRAITS?
Natural selection can only act on traits that have a genetic basis, meaning they are heritable and can be passed from one generation to the next. These traits must also affect an organism's fitness, influencing its ability to survive and reproduce in its environment. Additionally, natural selection operates on phenotypic traits, which are the observable characteristics resulting from the interaction of genetics and the environment. Traits that are not expressed or that do not impact survival and reproduction are not subject to natural selection.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
Can natural selection act upon body shape?
Yes, natural selection can act upon body shape by promoting traits that enhance an organism's ability to survive and reproduce in its environment. For example, organisms with body shapes that improve their efficiency in obtaining food or avoiding predators may have higher fitness and be more likely to pass on their genes to the next generation.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.

What is the selective agent in natural selection?
They are the selective agent in natural selection ;)
What is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
The process by which individuals that are better adapted to their environment are more likely to survive and reproduce is called?
natural selection
How does environment select organisms?
natural selection
Does natural selection cause changes in the environment?
No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
Does natural selection act on the phenotype?
yes
What is the degree of adaptation to a specific environment?
Natural Selection.
What concept of evolution explains why organisms are constructed to meet the demands of their environment?
Natural selection explains adaptive change in the immediate environment.
How environmental factors contribute to evolution by natural selection.?
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What does natural selection only act on?
It acts on populations.
