Which of the following might restrict the growth of a population?
O Mild winters
O Increased predation
o Increased numbers of prey
O Ample rainfall
30 POINTS!!!!
Answer: Increased predation, and mild winters.
Explanation: As the prey population increases, there is more food for predators. So, as the number of predators increases, more prey are captured.
Mild winters would cause all of the plants to die, therefore prey would also die due to lack of food and cause predators to die as well for the same reason.
Side note: It might also be ample rainfall but I didn't know if they meant ample rainfall as in flooding or not, if it means flooding then that could be an answer, too. And I also wasn't sure if this was multiple choice or not.
Good luck! :)

How does Earth’s position relative to the Sun cause the four seasons?
a. Earth orbits the Sun once a year and is in a different position with respect to the Sun every three months, resulting in four seasons.
b. The tilt of Earth’s axis with respect to its orbit changes back and forth approximately 46 degrees every six months, resulting in four seasons.
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
d. Earth rotates on its axis every twenty-four hours, and, since the axis is tilted with respect to the Sun, different parts of Earth experience different day-lengths, resulting in four seasons
Answer:
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
Explanation:
Earth’s tilted cause the four seasons in different parts of earth. In summer, the surface of earth is present directly to the sun causes high temperature of that region while on the other hand, the same region experience cold temperature in winter due to tilt of the earth which does not allow the solar radiation comes directly to that region of the earth that leads to cold temperature.

How are humans circulatory system similar and different to other animals
Answer:
Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.
Humans circulatory system is similar due to presence of artrium and ventricles and different to other animals due to number of heart chambers.
How human circulatory system similar and different to other animals?Humans have a heart with two atria and two ventricles that prevents bactward flow of blood. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle that can push blood in two directions.

PLEASE HELP!!!!!! 100 POINTS!! Lab: Absorption and Radiation by Land and Water
Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
The lab report is composed of three sections:
Section I: Experimental Overview
o Provide background information.
o Include the hypothesis.
o Summarize the procedure.
Section II: Data and Analysis
o Include graphs to display trends in the data.
o Identify trends in the data.
Section III: Conclusions
o Identify if the hypothesis was supported or refuted.
o Provide logical reasoning based on data.
o Explain how the experiment could be improved.
To help you write your lab report, you will first answer the eight questions listed below based on the experiment that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn in to your teacher.
You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool.
Questions
Section I: Experimental Overview
1. What is the purpose of the lab?
2. What is your hypothesis for this experiment?
3. What methods are you using to test this hypothesis?
Outline the steps of the procedure in full sentences.
Section II: Data and Analysis
4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following items:
a. An appropriate title
b. Appropriate labels for each axis
c. An appropriate scale for each axis
d. The correct units for the data
Complete a rough sketch of each graph.
5. What do the data in your graphs tell you?
Explain in one or two sentences what trend is shown in each of your graphs.
Section III: Conclusions
6. What do the data tell you about your hypothesis?
State how your hypothesis is either supported OR refuted by the data.
7. How do the data support your claim above?
Explain your statement above. Be sure to refer to specific pieces of data from your experiment that support your argument.
8. If you could repeat the experiment and make it better, what would you do differently and why?
There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.
Answer:
First read the student guide to understand everything that will occur in this lab. Second read the safety guideline to ensure no one is harmed during this lab. Then gather your materials for the lab. After that section off your grass into 32 sections. Choose a quadrant and make some observations. Then choose a random sample area in your quadrant to estimate how many individual pieces of grass are present. Next, fid the average height of thegrass. Then, compare the data to quadrant #18. Plant your seeds. Count how many blades of grass are in your random sample area, and then calculate the estimated number of blades in your quadrant. Find the average height of the grass. Compare your data once again to quadrant #18, which is in the control group. Record the height of all the plants and calculate the average height for each type of plant. Compare this data with the data from quadrant # 18. Combine the data from all quadrants, and then compare the data from the experimental group to the control group. Make sure you record all your data.

Who does not need a circulatory system?A single-celled organism that doesn't required the circulatory system as human do. Since they are the singular, they can interact with their environment directly. Oxygen need to be supplied by the circulatory system and some of the cells also well differentiated so it can be only accept a certain processed food.
Most mollusks, or except for the some particular cephalopos like skids, have an open circulatory system in which the circulating fluid has been called hemolymph that flows through the body thanks to the muscle contractions that pump this fluid into the hemolymph vessel that discharges this fluid into the body cavity allowing substances and gases to be exchanges between body cells and the carrying hemolymph. Then this fluid goes back to the blood vessel and reinitiates the circulation.
Therefore, Thus, option C is correct.
