What are advantages of variation?
Advantage- On the species level, variation allows a population to maintain a healthy diversity, allowing it to cope with changing circumstances.Disadvantage- On the individual level, variation may lead to detrimental changes as well as neutral and beneficial changes.
How does genetic combination help a species to survive?
It causes diversity and variation amongst a population
The course of evolution can be affected by changes to continents climate sea level and other factors in the environment When have these changes occurred?
Changes to continents, climate, sea level, and other environmental factors have occurred throughout Earth's history. These changes have happened over millions of years and have shaped the course of evolution. For example, the breakup of continents and the formation of new ones have created barriers that isolated species and led to the development of new species. Climate change has also influenced the distribution of species and their adaptations, while changes in sea level have created opportunities for migration and colonization of new habitats.
What are the two main factors that cause individuals of the same species to appear different?
I think it's environmental and genetic.
Why do you think that some species of plants and animals are becoming extinct in time?
Some species are becoming extinct. It is due to various environmental factors. Deforestation, ozone depletion are some.
What factors could be important for a species to evolve by natural selection?
Environmental change and variation :)
What causes variation within species?
Variation within species can be caused by genetic mutations, environmental factors, and interactions between genes and the environment. Genetic mutations are changes in the DNA sequence that can create new traits. Environmental factors, such as diet and climate, can also influence variation by selecting for certain traits over others.
During ecological succession the species composition of a plant community generally?
Changes gradually because each species responds differently to changes in environmental factors.
What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
What term describes changes that within species?
variation
How do the Grants data show that genetic variation is important in the survival of a species?
The Grants' work shows that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
How does variation within a species bring about evolutionary change need specific example that also mentions genetic variation and environmental conditions?
yes
Why are endangered species more vulnerable to environmental changes?
because they are
What are the factors affecting water use efficiency?
-species varieties -genotypes -environmental factors
When environmental conditions change it is more likely that at least some members of a species will survive if?
When environmental conditions change it is more likely that at least some members of a species will survive if there is variation among the members.
When environmental conditions change it is more likely that at least some members of a species will survive if they?
there is variation among the members.
How does variation within a species increases its chance to survive when the environment changes?
The differing traits provided by variation mean that at least some groups of the species may be better prepared to survive.
