Which of the following correctly states the relationship between monkeys and humans?
A. Humans and monkeys evolved from apes.
B. Humans evolved from monkeys.
C. Humans and monkeys evolved from the same ancestor, which is now extinct.
D. Humans evolved from apes and monkeys evolved from a small mammalian ancestor, which is now extinct.
Under which of the following conditions will speciation not occur?
A. Logging operations in a forest cut a single population of beetles in two so that they can no longer mix.
B. Some snails in a population develop shells that twist to the right instead of the left, which makes mating impossible with partners of opposite shell shape.
C. A newly constructed housing development divides the habitat of a bird species in two, forcing the birds to fly from one section to the other.
D. Some females of a species of spider prefer to mate with males that have red markings while other females prefer to mate with males with no markings.
Luther Burbank was a plant breeder who developed a strain of potato plant that produced more tubers of larger size than other potato plants that were grown on farms at the time. This strain of potato was also resistant to the potato blight that had wiped out the potato crops in Ireland in the mid-1800s. How did Burbank's process in developing this potato compare to the process of natural selection?
A. Burbank's process was slower.
B. Burbank's process did not affect the genetic makeup of the potato.
C. Burbank's process did not place the potato plant under any type of selection.
D. Burbank's process did not involve environmental pressures to shape the outcome.
How did Lamarck and Darwin differ in their thinking about species?
A. Darwin thought that organisms could induce their own changes, while Lamarck thought that change could only be induced by an organism's environment.
B. Darwin thought that change could occur in individual organisms, while Lamarck thought that change could only occur across generations.
C. Darwin thought that genes controlled a species' ability to survive, while Lamarck thought that genes were only one part of a species' ability to adapt.
D. Darwin thought that organisms had to struggle to survive, while Lamarck thought that organisms could make adjustments when conditions became difficult.
My answers: C, C, D. You gave me a website a couple of days ago, so I think it is D.
2 is not c.
Yes. A is right.
Okay, thank you for all your help!
You're welcome.
what about number 4 is tat also d i am trying to understand evolution much better.

Would this answer be D? Thanks
Was the answer D?
Yea i think so
i can't remember
Darwin thought that organisms had to struggle to survive, as Lamarck thought that organisms could just make adjustments anytime.
Great job on answering the questions! Let me explain how you got to the correct answers:
For the first question, the correct answer is C. Humans and monkeys evolved from the same ancestor, which is now extinct. This is because humans and monkeys share a common ancestor but did not evolve from each other.
Regarding the second question, the correct answer is A. Logging operations in a forest cut a single population of beetles in two so that they can no longer mix. Speciation occurs when two populations of the same species become reproductively isolated from each other. By cutting a single population in two, the beetles can no longer mix and are effectively isolated, potentially leading to speciation.
For the third question, the correct answer is D. Burbank's process did not involve environmental pressures to shape the outcome. Unlike natural selection, which involves the environment acting as a selective pressure, Burbank's process focused on deliberate breeding and selection by the plant breeder to obtain desired traits.
Lastly, for the fourth question, the correct answer is B. Darwin thought that change could occur in individual organisms, while Lamarck thought that change could only occur across generations. Darwin's theory of evolution by natural selection proposed that small variations within a population could lead to changes over time, while Lamarck's theory suggested that acquired traits during an organism's lifetime could be passed on to future generations, which has been disproven by modern genetics.
As for providing you with a website a couple of days ago, I'm an AI language model and don't have the capability to recall specific interactions or previous recommendations. However, there are various websites and resources available, such as scientific journals, educational platforms, and reliable sources like the National Geographic or Stanford Encyclopedia of Philosophy, that can provide more in-depth information on these topics.
