Why does natural selection have little effect on senescence? Genes that cause senescence have no variants because they became fixed early in evolutionary history. Low-calorie diets, which may not affect offspring, cause individuals to go through senescence. Reproduction generally occurs before senescence genes begin to produce harmful effects on fitness. Senescence is a result of getting older and is not controlled by genes that can be inherited.

Voles that are born in the Spring have thin coats as adults, while voles that are born in the Fall have thick coats as adults. Most voles live only a few months; voles born in the Spring are alive during the warm summer season, while voles born in the Fall are alive during the cold winter season. The environment experienced by the mother during pregnancy determines coat thickness in the offspring. Now consider a situation in which the environment the vole mothers during pregnancy changes, such that voles born in the Fall now have thin coats. Assume in this case that the Winters are still cold. This scenario provides an example of which of the following hypotheses? a.Environment mismatch hypothesis b.Endocrine disruptor hypothesis c.Thrifty genotype hypothesis d.Plasticity first hypothesis
Which of the following statements about the theories of senescence is correct? Question 2 options: The reason why organisms become old and decrepit is because an individual would often have accumulated too much energy in its lifetime in the form of fat reserve; therefore, an older individual often dies from old-age related diseases. An allele that shows its deleterious effect later in life will always have a smaller impact on an organism's fitness than an allele that shows its deleterious effect early in life. Therefore, late-acting deleterious mutations can be fixed in the population, resulting in shortened lifespans. The allele that can result in early reproduction will always be selected for, even if it comes with a cost of earlier senescence. Typically, for species that live fast would usually die young. None of the above
Evolution by natural selection is founded on what basic idea? Random genetic mutations that help a species survive will be more likely to be passed to future generations. Only traits that will help an individual organism survive will be passed down to future generations. Only the biggest, strongest, fastest, or smartest creatures survive. Traits that animals acquire over their life will be taught to future generations.
The sex of sea turtle offspring is determined by temperature during development. Temperature over 87° Fahrenheit will result in female offspring. What is the correlation between environmental factors and natural selection in how the sea turtle might adapt to the rise in ocean and air temperatures.
Which factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection? the impact of UV radiation on folate and Vitamin D levels in human populations the clothing worn by humans in the early 8th century the interaction of human populations with predators in colder climates a change in the diet of human populations as they settled in colder climates
What factors caused the correlation between the reduction in skin pigmentation in humans and migration of human populations away from the equator? The exposure of human populations to predators only common to the polar regions caused them to adapt by camouflaging better with the environment. The exposure of human populations to less UV light required a reduction in melanin to produce more vitamin D for healthier bones. The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin. The exposure of human populations to new diseases common to the polar regions interferred with melanin production causing lighter skin.
Paedorphosis can occur when a feature ______in a descendent than in its ancestor. stops growing later grows more slowly grows faster all of the other answers are correct
Why are fruit flies good subjects with which to observe the process of evolution through natural selection? Fruit flies are good subjects because they have very long generations, and scientists can control their development over long periods of time. Fruit flies are good subjects because they have short generations and scientists can control their development in the lab. Fruit flies change into different species of flies each generation, so they have more features to study. Fruit flies are K-strategists, and these are easier to study over short periods of time.
Humans have been affected by genes and the environment, including the cultural environment. True False The secular trend in puberty has resulted in a decrease in the age of menarche in human females. True False According to “The Story of Race”, what did the eugenics movement in the U.S. seek to prove? That all men and women were biologically equal. That systematic discrimination against immigrants was unacceptable. That the racial superiority argument put forth by Nazi Germany was immoral and incorrect. That lower intelligence and criminal behavior were genetically based traits of the lesser races.
Which of the following best explains the phrase “survival of the fittest” in terms of evolution by natural selection? The strongest and fastest individuals will always survive and reproduce more often. The individuals that are the healthiest will always get more resources and survive better. Only individuals that have the most mates will survive with limited resources. The individuals that survive better and reproduce more often will pass their traits on more often.
Researchers are very interested in studying identical twins separated at birth and raised apart. So far, data suggests that such twins are more alike than researchers predicted; they frequently have similar personalities, mannerisms, habits, and interests. What general questions do you think researchers hope to answer by studying such twins? Why do identical twins make good subjects for this research? What abuses might occur if the studies are not evaluated critically and if the results are carelessly cited to support a social agenda?
There are some dinosaurs that have a mutation that causes a decreased ability to withstand temperature changes dues to an overall decrease in fatty tissue. Are there any environmental changes in which the non-mutants would be better adapted than the mutants? If so which? And are there any environmental changes in which the mutants would be better adapted than the non-mutants? if so which? Are there any scenarios in which neither the mutants nor the non-mutants will be better-adapted? Are there any scenarios in which both the mutants and the non-mutants will survive equally well?
