Please check my answers:
1. 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.
I think the answer is C.
2. 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.
I think the answer is C.
3. 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.
I think the answer is C or perhaps D.
4. 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.
I think the answer is C or D.

if you go to CA these are the answers:)
1. To answer this question, we need to understand the relationship between humans and monkeys. Option A states that humans and monkeys evolved from apes. Option B states that humans evolved from monkeys. Option C states that humans and monkeys evolved from the same ancestor, which is now extinct. Option D states that humans evolved from apes and monkeys evolved from a small mammalian ancestor, which is now extinct.
To determine the correct answer, we need to consider the commonly accepted scientific understanding. The most accurate option is C, which states that humans and monkeys evolved from the same ancestor, which is now extinct. This is supported by the evidence of shared genetic and anatomical traits between humans and monkeys.
2. To answer this question, we need to determine the condition under which speciation will not occur. Option A states that logging operations separate a population of beetles. Option B states that some snails develop shells that make mating impossible with counterparts of opposite shell shape. Option C states that a housing development divides the habitat of a bird species. Option D states that some females of a spider species have different preferences for mates based on markings.
In order for speciation to not occur, it would require the populations to remain connected and freely interbreed. Option C states that a housing development divides the habitat of a bird species, forcing them to fly from one section to the other. This would limit gene flow between the separated populations, making speciation more likely to occur. Therefore, the correct answer is not C.
3. To answer this question, we need to compare Luther Burbank's process of developing a potato strain with the process of natural selection. We can eliminate options A and D because these statements are not true.
Natural selection involves environmental pressures that shape the outcome of the population, whereas Burbank's process likely did not involve such pressures. This eliminates options B and D. Therefore, the correct answer is C, which states that Burbank's process did not place the potato plant under any type of selection.
4. To answer this question, we need to understand the differences between Lamarck and Darwin's thinking about species. Option A states that Darwin believed organisms could induce their own changes, while Lamarck believed change could only be induced by the environment. Option B states that Darwin believed change could occur in individual organisms, while Lamarck believed change could only occur across generations. Option C states that Darwin believed genes controlled a species' ability to survive, while Lamarck believed genes were only one part of a species' ability to adapt. Option D states that Darwin believed organisms had to struggle to survive, while Lamarck believed organisms could make adjustments when conditions became difficult.
The correct answer is D because it accurately represents the differences between Lamarck and Darwin's thinking. Lamarck proposed that organisms could actively make adjustments to adapt to their environment, while Darwin proposed that survival is determined by the struggle for existence in which only the fittest individuals survive and reproduce.
5. To answer this question, we need to consider the evidence that supported the idea of evolution when it was first proposed. Option A suggests observations of nature. Option B suggests laboratory experiments. Option C suggests extensive fossil collections. Option D suggests genetic sequences.
When evolution was first proposed, the primary evidence supporting the idea came from observations of nature, such as the pattern of similarities and differences among living organisms and the presence of vestigial organs. Therefore, the correct answer is A.
