You are given a new situation: Michael is planning on playing a prank on his older brother. He is going to take a bungee cord and stretch it and then release it so that it hits his older brother as he is sleeping. He is deciding whether to stretch the cord only partially or completely before releasing it. and a hint : Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL: Please answer this question : Will stretching the bungee cord partially or completely result in less force when it's released?

Answer: partially

You are given a new situation: A species of animal called a markalong was discovered that can reproduce either sexually or asexually. Two markalongs were just born from different families in a zoo. The first markalong, animal A, has only one parent. The second markalong, animal B, has two parents. Although they used different forms of sexual reproduction, both animals are healthy and doing well at the zoo. and a hint : The advantage of asexual reproduction is that it can be very quick and does not require the meeting of a male and female organism. The disadvantage of asexual reproduction is that organisms do not receive a mix of traits from both parents. An organism that is born through asexual reproduction only has the DNA from the one parent. In fact, the offspring is genetically an exact copy of the parent. This can cause problems for the individual. For example, if the parent has a gene that causes a particular disease, the offspring will also have the gene that causes that disease. Organisms produced sexually may or may not inherit the disease gene because they receive a mix of their parents' genes. Please answer this question : Which markalong was produced asexually?

Answer: animal A

You are given a new situation: Two cities had different energy source. Big city burned fossil fuels cut forests and cleared land, while Blue city used alternative sources of energy. and a hint : Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. Please answer this question : Which city destroyed fewer autotrophic organisms?

Answer:
Blue
