How are organisms and populations affected by environmental changes?
Organisms may experience changes in their habitat, food availability, and climate due to environmental changes, which can lead to shifts in behavior, reproduction, and distribution. Populations may decline if they cannot adapt to these changes, leading to reduced genetic diversity and increased vulnerability to diseases and other threats. Adaptation, migration, and extinction are some of the responses organisms and populations may have to environmental changes.
What couldn't be explained by Darwins theory of evolution?
Evolution only deals with the changes within populations of organisms. All other sciences, including Astronomy and Cosmology, are mostly unconcerned with the theory. Otherwise, the theory was, and is, completely sound.
The principal problem with inserting an unmodified mammalian gene into the bacterial chromosome and then getting that gene expressed is that?
bacterial and mammalian cells have different genetic codes and regulatory mechanisms, making it difficult for the bacterial cell to properly transcribe and translate the mammalian gene. This can result in the gene not being properly expressed or expressed with errors, leading to potential harmful effects or lack of desired function. Additionally, the post-translational modifications required for mammalian proteins may not occur in bacterial cells.
Random change in the frequency of a gene is called?
A random chamnge in the frequency of a gene is called genetic drift.There is disagreement about how much genetic drift occurs in nature, but it cannot be responsible for producing adaptations. Natural selection is the only known scientific mechanism for producing the adaptations which we see in all organisms.
Why is low genetic variation a problem?
Low Genetic variationis the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction.
If a certain species has little genetic variation what could lead to its rapid extinction?
A lack of genetic variation can make a species less able to adapt to changing environmental conditions or new threats like diseases or predators. This reduced ability to adapt increases the species' vulnerability to extinction if they cannot effectively respond to these challenges.
Explain why individuals cannot evolve?
Individuals die. Only the progeny of individuals carry on the genetic variation that is in populations. Selection works on this variation in populations by working on variation passed along by the sex cells. Somatic cells of the individual can have any mutation, but can not pass it on to progeny. Sex cell, having mutation which allow selection to choose among variation, lead to evolutionary processes.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.

What is the process by which members of isolated populations become so different in genetic makeup that they cannot produce life?
The process by which members of isolated populations become so genetically distinct that they can no longer interbreed is called speciation, often occurring through mechanisms like allopatric speciation. When populations are separated by geographic barriers, such as mountains or rivers, they experience different evolutionary pressures and mutations over time. This genetic divergence can lead to reproductive isolation, where even if the populations come into contact again, they are unable to produce viable offspring due to differences in mating behaviors, genetic incompatibilities, or other barriers.
Why do all populations face limits to growths?
Populations run out of food and space so cannot grow indefinitely.
A population of anole lizards cannot find enough food in their ecosystem so they immigrate into a new ecosystem and join another population of anole lizards What will happen to the genetic composite?
Both populations will become more genetically diverse.
Can two clones have a baby?
No, two clones cannot have a baby together because they share the same genetic material, which means they lack the necessary genetic diversity for reproduction. In sexual reproduction, genetic variation is crucial for creating a viable offspring, and clones would not provide that diversity. Additionally, cloning typically involves replicating a single organism, which does not include the reproductive processes required for creating a new individual.
Is the flu bacterial?
yes last time i checked i read all viruses and flu's were bacterial! No, influenza is viral and cannot be treated with antibiotics.
Would you expect the rate of speciation to be higher or lower for animals that cannot swim Explain.?
The rate of speciation for animals that cannot swim is generally expected to be lower. This is because swimming often facilitates dispersal and gene flow between populations, allowing for greater genetic diversity and adaptation to different environments. In contrast, non-swimming animals are typically more restricted in their movement, leading to isolated populations that may experience reduced chances for genetic exchange and slower rates of speciation. Additionally, habitat fragmentation can further limit their opportunities for divergence and adaptation.
What is the condition in which two populations cannot interbreed called?
isolation
