12. Which of the following best explains how meiosis, followed by fertilization, ensures genetic variation?A. Changes in an orga
nism's DNA during prophase creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces the same allele combination as the parent and results in each member of a sexually reproducing population having a unique combination of traits.B. Changes in an organism's DNA during prophase I creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces variation that results in each member of a sexually reproducing population having a unique combination of traitsC. Changes in an organism's DNA during telophase creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces variation that results in each member of a sexually reproducing population having a the same combination of traits.D. Changes in an organism's DNA during telophase I creates different versions of alleles. Reshuffling of the alleles during sexual reproduction produces variation that results in each member of a sexually reproducing population having a unique combination of traits.
Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
The neural pathway carries crude information about a threatening stimulus and activates a rapid instinctual alarm response is the thalamus→amygdala pathway
The thalamus→amygdala pathway is also known as the the path of fear. The thalamus transfers signal to other parts of the brain that causes the release of adrenaline and stress hormones.
The answer is: the source of information could be biased
The scientist is interviewing environmentalists and then generalized their opinion as "people". An environmentalist is a person that cares about the environment, so they will more likely to deny the option that harms the environment. If the dam harmful to the environment, most environmentalists will not approve it.
