Period 4 Characteristics of Life by Yer Lawson https://padlet.com/ylawson/27fhuoxqd5zd en-us 2016-11-14 17:41:02 UTC 2016-11-15 19:26:58 UTC hello@padlet.com Directions: 1. Choose one of the following scenarios to respond to. Be sure to include at least one characteristic of life. 2. Then respond to someone else's response. ylawson https://padlet.com/ylawson/27fhuoxqd5zd/wish/137468764 2016-11-14 17:41:38 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137468764 Scenario 1: Most people think it is easy to tell the difference between an organism that is alive or dead. But, is it? I dug a cactus out of a garden in my yard and lay it on it’s side on top of the patio. I planned to replant it somewhere else in the yard, but got busy and forgot. After a few weeks, it was all brown and shriveled looking. I felt badly that I had let the cactus die. A friend who is an experienced gardener was visiting me and saw my dead cactus and told me that if I put it in the ground and watered it, it would “come back” and be just fine. I tried it and it worked! I couldn’t believe it- over the next couple of weeks it grew new branches that were bright green and eventually blossomed. How was I able to bring this cactus back from the dead? Was the cactus dead? What happened here? ylawson https://padlet.com/ylawson/27fhuoxqd5zd/wish/137468819 2016-11-14 17:41:44 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137468819 Scenario 2: There have been times in which a person was thought to be dead and they turned out to be alive. For example, a woman's dead body was brought to the morgue for an autopsy and then when the medical examiner started his procedures she responded and it turned out she was alive. A man's dead body was laid out for his family members to view at a church. As the organist played his favorite hymn, he sat up and wanted to know what was going on. Centuries ago the fear of being buried alive was probably a more realistic fear than it would be now. A few people were so worried about this that they patented inventions such as a bell that stayed on the top of the ground and was attached by a cable through the ground to the inside of the coffin below so that a person who was buried alive would be able to ring the bell to get attention. The invention was never used, but it shows the fear was very real and there may have been a few people who were buried alive in the past. How could these things have happened? How do medical professionals determine when someone's life ends? What are the 'signs of life' they need to look for (use a characteristic of life for this part)? ylawson https://padlet.com/ylawson/27fhuoxqd5zd/wish/137468863 2016-11-14 17:41:49 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137468863 Johnathan Harris - Scenario 2 jharris106201 https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566415 This could have occurred due to the absence of visible cellular processes but continued brain activity. Medical professionals determine death by checking processes that use energy such as respiration or heart rate (blood flow).]]> 2016-11-14 21:54:40 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566415 Marrissa Zaragoza mzaragoza104236 https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566493 2016-11-14 21:55:05 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566493 Tanner Phillips https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566514 2016-11-14 21:55:12 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566514 Abigail fonseca afonseca500648 https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566582 The cactus was able to come back because it may have have some cells still alive. The cactus was not dead but it may have had some dead cells. What happened was the cells were given energy and water which helped regrow the plant.]]> 2016-11-14 21:55:31 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566582 Anthony Fisher afisher105775 https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566650 they also might put a hole all the way up to the surface so they can breath if they are really not dead so they can also think they are dead when they are knocked out and not really breathing or moving

No, the cactus was not dead. It was dehydrated and just needed water.

Many people have been buried alive i think and they dont get rescued. The bell is a good strategy to help those who got buried alive at one point ]]> 2016-11-14 21:56:48 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566811 Carlos Bucio cbuciomendoza105708 https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566841 I think the cactus survive because it saved energy and water for later. Like when you are thirsty you get tired and save energy.

They can determine death by checking the heart beat. Some signs of life are energy, DNA, and cells

The cactus was never dead. When the plant received water, it responded to the environment by taking it in. The cactus was dried and dying, but the water rejuvenated it.]]> 2016-11-14 21:57:21 UTC https://padlet.com/ylawson/27fhuoxqd5zd/wish/137566920 The cactus was able to come back to life because you replanted it and gave it water and sunlight. No, the cactus wasn't dead the cactus was just dehydrated and needed water. The cactus started to get dehydrated so that's why it started turning brown and it was lacking in energy and sunlight. syang106087 https://padlet.com/ylawson/27fhuoxqd5zd/wish/137567066

I also think the cactus came back to life because the water went in to the plant and started to reproduce and bring the cells back to life. I don't think the cactus was dead it just needed nutrients.

These things could've have happened because someone missed a heartbeat. Signs of life they need to look for are a pulse.
