Answers

Answer:

The correct answer is - The cranial nerves and the spinal nerves.

Explanation:

The central nervous system or CNS includes the brain and the spinal cord of the nervous system where it takes sensory information, integrates, and responds accordingly. The spinal cord acts as a conduit for signals between the brain and the rest of the body.

Spinal nerves and crania; both play an essential role in taking sensory information and respond accordingly. Spinal nerves are nerves that help in sending motor, sensory, and autonomic signals between the CNS and the body. The cranial nerves supply information to the CNS and then from the CNS to the body.

Thus, the correct answer is - The cranial nerves and the spinal nerves.

After getting their results in, a group of scientists went back and looked at their study. As planned, their experiment consisted of three groups. The first group received a new medicine at a normal dose, the second group received the medicine at half the dose, and the third group received the medicine at twice the dose. Which of the following best describes what went wrong with the scientists’ study?

Answers

Answer:

Their experimental design lacks control group

Explanation:

Based on what I read, the scientists don't have a control group as one of the main groups thus they cannot, in scientific sense, say that the medicine is better or worse. You always need a control group receiving no intervention because then we can compare groups and assess the effectiveness of that intervention (in our case if we had control group vs people who received the medicine, we could see if the people who received the medicine had improved condition etc when compared to participants who did not receive anything)

There is no control group in their experimental design. According to what I've read, the scientists don't have a control group as one of the primary groups. Thus, option C is correct.

What is control group?

To determine if the treatment is better or worse in a formal scientific sense. You should always have a control group that does not receive any treatment because this allows us.

To compare the groups and evaluate the effectiveness of the intervention. In our case, if we had a control group and participants who did not receive any treatment, we could see if those participants had better health overall.

By focusing on the impact of a single independent variable, a cause-and-effect link can be established.

The independent variable is altered in the treatment group while being held constant in the control group by researchers. The findings of these groups are then compared.

Therefore, no control group in their experimental design.

A species of spruce tree occupies the same niche at the mouth of a river that a species of pine tree occupies further upstream. One year, several pinecones fall into the river and are carried to the mouth, where they take root and grow amongst the spruce trees. What will be the most likely result of this occurrence

Answers

Answer:

The correct option is: "Either the pine trees or the spruce trees will eventually evolve into a new species."

Explanation:

There will be a competition between spruce trees and pine trees for nutrition and other resources from the environment to grow and spread since they are now occupying the same niche. Overtime, one specie will outlive the other by evolving into a specie that gives it an advantage over the other.
