WHen organisms reproduce, they pass their characterisitcs on to their offspring through their genes. Organisms with characters not well suited for their environment are not as likely to survive to reproduce and pass on their characteristics. Organisms that are not able to reproduce and pass on their traits to their offspring die off, or become extinct.

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.

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.

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!!!!
Answers
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! :)

solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe. The lack of atmosphere would chill the Earth's surface. ... Plants and land animals would die
Explanation: rewrite it
The energy of ultraviolet and shorter wave lengths of light is absorbed by interaction with the molecules in the atmosphere.
Explanation:
If there were no molecules in the atmosphere the high energy waves from the sun would strike the surface of the earth. The result would be that perhaps no living thing could survive.
Ozone and other molecules absorb the energy from the sun and undergo chemical reactions due to the energy absorbed.

What are the two parts of food chain?Part 1 of the food chain describes organisms that are the end of the food chain, which would typically be consumers or animals that feed on other organisms, including plants and other animals.
Part 2 of the food chain refers to something that passes energy to plants and animals. This is typically the sun, which provides energy through photosynthesis to producers, or plants, that convert light energy into chemical energy stored in food. Producers form the base of the food chain, providing energy to all other organisms in the ecosystem through the food they produce.
