How does natural selection operate to cause a change in population?
Natural selection operates by favoring individuals with advantageous traits that increase their survival and reproduction rates. Over time, these individuals pass on these advantageous traits to their offspring, leading to a change in the population's characteristics as the frequency of these traits increases. This process results in the adaptation of the population to its environment.
How might global warming the evolution of living things?
Those organisms that had variations which caused to survive and be reproductively successful in the changing environment world fulfill the definition of evolution. The change in allele frequency over time in a population of organisms. Perhaps new species would arise from this change and perhaps not. Time and environment would tell.
Why is variation beneficial to a population that is undergoing change?
Yes, it is. If there is variation in a populations, and a sudden catastrophic event occurs, there is more of a chance that some of the individuals in the population will survive, and the population will not die out.
A change in structure or behavior that helps a living thing survive in its environment?
An adaptation is a change in structure or behavior that helps a living thing survive in its environment. It enhances the organism's ability to thrive and reproduce in its surroundings, increasing its chances of survival. Adaptations can result from genetic changes over time or through learning and behavioral modifications.
Why is it false that sexual reproduction is the only mechanism for genetic change?
I believe that mutations are considered to play a part, whether genetically mutated or selected by the changes in an environment. Eg. In a wet environment type A will survive and dominate the population thereby producing more type mutations As in the nxt generation. However, should a drought hit and type B carries the genes tht enable it to survive droughts better, then the 3rd generation will mostly contain type B mutants.
Why is a genetically diverse population the more likely to survive a change to the environment?
they are more likely to have individuals with an adaption
Why do people change their environment?
to survive or change our recouces
Does tigers adapt or change to survive in the environment?
no
Does the wolf adapt or change to survive in the environment?
yes
What is the short definition of adapt?
Change to survive in environment
Do polar bears adapt or change to survive in the environment?
adapt
Microevolution can occur when some individuals in a population survive and reproduce more often in a new environment?
Yes, microevolution can occur when some individuals in a population survive and reproduce more in a new environment. Natural selection can, over time, change the characteristics of entire populations.
What is the term for a trait that helps an organism survive and change to fit its environment?
An adaption.
What is a change in the environment that causes a. Response?
stimulus
How do wild beasts find their adaptation to help them survive?
It is called natural selection. The individuals with the best properties needed for survival in an environment are the most likely to survive, and to pass on their genes. In this way the offspring will have properties that are useful in an environment. In theory the population will start to move more and more towards having useful properties for their specific environment and circumstances. If the environment changes, the individuals that are most likely to survive will also change, and probably different properties will be favored this time.
Why are genetically modified organism beneficial?
Genetically modified organisms are modified on a genetic level to benefit humans. How this can pose a threat to a population or ecosystem, is that if the genetically modified organism were to somehow create a mutation, and pass that on, it could be damaging to the future generations in reducing their health or other issues may arise. It can also be damaging to an ecosystem if a genetically modified organism were to escape into a wild population and change it.
How does environmental change lead to adaptation?
Within a population of animals there are variations and differences. So when an environmental change occurs those animals that are better suited to that environment survive and are able to reproduce sucessfully. Those animals that cannot survive as well under the new conditions tend to reproduce less and die out, leaving just the offspring of those who could tolerate and thrive in the new environment. Thus passing on this ability to survive to their offspring leaving a population well suited to the new environment.
