How Gases Are Exchanged in a Chicken Egg Problem: How can the chicken exchange gases during the 21 day period of development? Introduction: In humans, the embryo will receive all its needs from the mother, specifically from the placenta. One of these vital needs, which is oxygen, is sent to the embryo through the umbilical cord within the mother. However, for animals such as the chicken, the embryo is not developed inside a mother, but rather inside an egg, prompting the question as to how gases are exchanged in an egg. One suggestion would be that there is enough air in an egg to last the chicken 21 days, but that can’t possibly be correct because the chicken is constantly growing, making no room for oxygen.

The woman even made her dogs peanut butter and honey sandwiches, and let them sleep inside her bivvy sack. She treats them almost as children, as any other human beings in need of love. Although she’s camping in thirty below weather, the only things she gets from it are positive. She ends her trip with this closing, “On Sunday I had a glimpse outside of the house of mirrors, on Saturday I couldn’t have seen my way out of a paper bag” (281). Nature and her companions had given her happiness, which nothing else seemed to be capable
Tha’s three hundred an’ fifty bucks I’d put in. I ain’t much good, but I could cook and tend the chickens and hoe the garden some. How’d that be?”(65) “I gotta think about that. We was always gonna do it by ourselves.… I bet we could swing her for that. Then you an’ Lennie could go get her started an’ I’d get a job an’ make up the res’, an’ you could sell eggs an’ stuff like that.”(65-66) This shows George and Lennie have a perfect dream.
Harper Lee’s theme can also be comprehended through the symbol of the mockingbird. When Atticus gifts his children with air soft guns he advises them that if they went shooting for birds he tells them, "shoot all the blue jays you want, if you can hit'em, but remember it's a sin to kill a mockingbird" (96). Miss Maudie furthers Atticus’s explanation by saying, "mockingbirds don't do one thing but make music for us to enjoy. They don't eat up people's gardens, don't nest in corncribs, they don't do one thing but sing their hearts out for us. That's why it's a sin to kill a mockingbird" (96).
“Wake up, Jay” My mother called on a Monday morning, “time for school.” “Oh great” I thought, “3 miles there, 3 miles back.” I went to Armrail Elementary School with my brother and sisters. Not a lot of kids went to school back then. When we get home from school, we help out in the garden. We grew potatoes, tomatoes, okra, and corn. We also raised chickens for eggs and chicken.
Hannah claimed she was shocked to find out that kids approached an injured bird and picked it up because she would have gone for help first. Also, that she would want to know if the bird lives in the end. Hannah demonstrated an understanding of the story responding to questions after reading the text, as she was able to figure out the author’s purpose in writing this story which she stated was to show how caring people can help injured animals. Hannah’s understanding of the material enables her to draw similarities and differences that occurred in the beginning, middle and the end, as well as by identifying the “moral” of the story. We continued to read “Revolting Rhymes” the story we read today was Little Red Riding Hood.

Keen, Melinda’s biology teacher, teaches the students about plants. Melinda thinks it’s really cool because she feels as though plants are just like humans. To just get the plant to grow you have to plant it just right, or else it will never make it or have troubles surviving. If the seed is planted too deep, it doesn’t warm up at the right time. Plant it too close to the surface, and a crow eats it.
