if a species population were exactly the same with no variation then it die out. for example in Ireland during the potato famine, they grew the same potato that all the potatoes got infected with something that wiped out all the crops. Another example if every human had the same immune system then a disease could wipe out the entire human race. So if we where different then the species itself would have a better chance of surviving

How does genetic variation contribute to a species' ability to survive and adapt to changing environments?
Genetic variation allows a species to have different traits and characteristics within its population. This diversity increases the chances that some individuals will have traits that are better suited to survive and thrive in changing environments. As the environment changes, individuals with advantageous traits are more likely to survive and reproduce, passing on their genes to future generations. This process, known as natural selection, helps a species adapt and evolve over time.
Why mutations can be helpful to a species?
Mutations can introduce new genetic variations into a population, which can drive evolution by providing diversity for natural selection to act upon. This diversity can lead to individuals with advantageous traits better suited to their environment, ultimately enhancing the species' ability to survive and reproduce.
What is true about the gene pool and genetic diversity?
A diverse community is a community populated by people from many different backgrounds; differences in background such as social, economic, religious, ethnic, or country of origin.
What are two factors that allow organisms to live on earth?
Adaptation to environmental conditions and the presence of essential resources such as water, air, and nutrients enable organisms to survive on Earth. Additionally, the ability to reproduce and pass on genetic information ensures the continuation of species on the planet.
Is their any genetic features to help to survive?
Yes, certain genetic features can influence an individual's ability to survive in challenging environments. For example, genetic variations that provide increased resistance to diseases, improved metabolism of nutrients, or enhanced ability to adapt to changes in the environment can positively impact survival. However, environmental factors and lifestyle choices also play a significant role in determining overall health and survival.
What changes account for the ability of a species to evolve?
Changes in the genetic material of the species, such as mutations and genetic recombination, can create new variations. Natural selection acts on these variations, allowing individuals with advantageous traits to survive and reproduce, leading to evolution of the species over time.
What are 5 traits of an animal?
Ability to move and respond to stimuli. Genetic inheritance and variation within species. Need for energy and nutrients to survive. Ability to reproduce and pass on genetic information. Adaptability and responsiveness to environmental changes.
How does genetic variation contribute to a species' ability to survive and adapt to changing environments?
Genetic variation allows a species to have different traits and characteristics within its population.

This process, known as natural selection, helps a species adapt and evolve over time.
How does genetic combination help a species to survive?
Genetic combination increases genetic diversity within a species, providing a wider range of traits and characteristics. This diversity can enhance a species' ability to adapt to changing environments and challenges, increasing its chances of survival and evolution. Moreover, genetic combination can help dilute harmful mutations and increase the chances of beneficial ones being passed on to future generations.
Why is genetic homozygosity dangerous to a nearly extinct species?
Genetic homozygosity can be dangerous to a nearly extinct species because it reduces genetic diversity, which is crucial for adaptability and resilience to environmental changes, diseases, and other stressors. With a limited gene pool, the population may face inbreeding depression, leading to a higher likelihood of genetic disorders and reduced fertility. This lack of variation can ultimately hinder the species' ability to survive and recover, making them more vulnerable to extinction.
What enables a species to adspt and survive?
A species' ability to adapt and survive is primarily determined by its genetic diversity, which provides a range of traits that can be beneficial in changing environments. Natural selection plays a crucial role in this process, as individuals with advantageous traits are more likely to reproduce and pass those traits to future generations. Additionally, factors such as environmental variability, availability of resources, and interactions with other species can influence a species' adaptability. Overall, a combination of genetic, ecological, and evolutionary factors contributes to a species' resilience and survival.
What is a genetic pool?
A gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Thus the actively interbreeding population of a species is a genetic pool comprising the genes for that species. Should something happen that would separate the breeding population into two populations where the populations could not longer mingle to interbreed, there would now be two genetic pools.
Why mutations can be helpful to a species?
Mutations can introduce new genetic variations into a population, which can drive evolution by providing diversity for natural selection to act upon. This diversity can lead to individuals with advantageous traits better suited to their environment, ultimately enhancing the species' ability to survive and reproduce.
What is true about the gene pool and genetic diversity?
A diverse community is a community populated by people from many different backgrounds; differences in background such as social, economic, religious, ethnic, or country of origin.
Why are emperor penguins considered a species?
Emperor penguins are considered a species because they share a unique set of biological and genetic characteristics that distinguish them from other penguin species. They exhibit specific behaviors, reproductive strategies, and adaptations to their cold environments, such as their ability to survive harsh Antarctic winters. Additionally, they can interbreed only within their species, reinforcing their classification as a distinct species in the animal kingdom.
How does genetic variation prevent extinction of a species?
Genetic variation allows individuals within a species to have different traits that might be advantageous in changing environmental conditions. This diversity increases the chances that some individuals will survive and reproduce when faced with new threats or challenges, helping to prevent extinction. High genetic variation also provides a larger pool of traits for natural selection to act upon, promoting the species' ability to adapt over time.
What is a characteristic that improves a individuals ability to survive and reproduce in a particular environment?
having genetic variation among most of its members
