Variations
This term describes the differences in traits like color, size, or behavior among individuals in a population.
Variation
When two plants grow close to each other and need the same sunlight and water, they are engaged in this kind of struggle.
Competition
This phrase describes how organisms with traits that improve their chances of survival and reproduction are more likely to pass those traits to the next generation.
Survival of the Fittest
In flowering plants, reproduction often depends on the transfer of this substance, which contains male gametes, from one flower to another.
Pollen
This term refers to a group of organisms that can interbreed and produce fertile offspring, sharing common characteristics.
Species
Variations in these physical or behavioral traits increase an organism’s ability to survive and reproduce in a specific environment.
Adaptations
Competition among individuals within a population usually intensifies when this happens to resources like food, water, or shelter.
Scarcity or lack of resources
Some animals survive by changing their color to match their environment, which is known as this type of survival advantage.
Camouflage or blending in
This type of reproduction involves only one parent and results in offspring that are genetic clones of the parent.
Asexual Reproduction
This process describes how populations of organisms change over generations due to natural selection, genetic drift, mutations, and gene flow.
Evolution
This process ensures that beneficial traits can be passed from parents to offspring in populations experiencing natural selection.
Inheritance
In the wild, animals like lions, wolves, and eagles that hunt other animals for food are known by this term.
Predator
When an environment changes, animals with beneficial traits may survive, while others without these traits may face this outcome.
Extinction
This term describes when a species produces more offspring than the environment can support, leading to competition for resources.
Overproduction
Favorable
This word refers to visible traits like height, coloration, or fur texture that can be observed directly.
Phenotype
When resources like food and space become limited, the size of this group of the same species in an area can be affected.
Population
These external conditions, like temperature, rainfall, and availability of resources, impact an organism's ability to survive and reproduce.
Environmental Factors
This term refers to the young produced by parents, carrying genetic material from one or both to continue the species.
Offspring
Two populations are separated. Over time, genetic differences accumulate, leading to the formation of a new species. At this point, these two populations can no longer _________.
Breed or reproduce
Random changes in DNA that introduce new variations into a population are known by this term.
Mutations
In competition for limited resources, animals must adapt to improve their chances of this.
Survival
This term describes an organism’s ability to survive and reproduce in its environment, often influenced by its adaptations and genetic traits.
Fitness
This term refers to multiple babies born at the same time to the same mother, commonly seen in mammals.
Litter
Which of the following factors does not play a significant role in the process of forming a new species?
Geographic isolation
Mutations
Reproduction
Environmental factors
Behavioral changes
Similar physical appearance?
