Levi Bourland Mrs.black Biology 10-6 10/6/16 Egg Lab Background info: hypertonic solution was used in the lab, hypertonic is the liquid substance that is going out of the egg. When a red blood cell has more water than what's outside then the water will come out and will become smaller. Hypotonic is when the water on the outside of the cell has more water than the inside, the water will go in the inside to make it run smoothly. Isotonic is when the inside and outside of the cell is each, they will stay the same. Question: which type of substance will rehydrate the dehydrated egg the best? Hypothesis: the Lemmon juice will rehydrate the cell the best. Justification: the lemon will hydrate the cell by the sugar that it will reform

Margaret Atwood's “Bluebeard's Egg” is a story centred upon a woman called Sally, describing her relationship with her husband, Ed, and her best friend, Marylynn. The story is told in a third person perspective, a “God-like” figure that takes us through the whole narration, but only revealing the thoughts of one character, Sally. In the story “Bluebeard's Egg”, the main conflict is within the protagonist, Sally; that is, her external self versus her internal self. Sally's external self does not act according to her internal self. In other words, Sally does not express her emotions and thoughts due to the many concerns that she has, both psychological and environmental.
For my egg drop project, I made mine out of balloons. I got the idea from a YouTube video called, Top 10 FIRST PLACE Egg drop designs! Science Experiment Challenge! The channel name is IncredableScience. The first idea, ( on the video) was the one I created. I first wrapped my egg in duck tape and then attached balloons. Finally I connected all of the balloons together using duck tape. At first I wasn’t going to wrap my egg with duct tape, but I found this duck tape barrier helped to attach the balloons later on. I dropped it from my balcony which is about 10 feet and it survived. The weather conditions were not bad, it had just finished raining. I thought this would work because in the video I watched, the same balloon idea
Gender stereotypes have existed since the beginning of modern man. We've all heard them before; male dominance and female weakness, a controlled male and a flustered female, aggression and passion, and many others that all basically boil down to the same thing. Emily Martin, in her essay entitled The Egg and the Sperm, takes this problem of gender stereotype to a new and much more serious level. As an anthropologist, Martin is concerned with the socio-cultural impacts on many different aspects of everyday life, including biology. In doing her research for this article, Martin was trying to uncover suspicions she had about socio-cultural gender stereotypes, and the affects they had on the diction used to describe egg and sperm interactions in numerous biology books and research reports.
Erythrocytes, or what are commonly known as red blood cells (RBC) within our bodies are constantly being faced with a changing environment. Tonicity is referred to as the concentration of solutes, permeable and nonpermeable, as well as the concentration of water both influencing the water that will come and goe through the RBC, and the surrounding fluid of the RBC (Sherwood, 2013). Osmosis on the other hand is known as the movement of water from an area of low concentration to an area of high concentration and this will happen across a cell’s membrane until it reaches a state where it is isotonic.
the gain or loss of water when samples of the tissue are placed in a
16. Describe two evolutionary consequences if the process of crossing over in meiosis ceased to occur. If crossing over in meiosis ceased to occur there would be less genetic variations and no diversity among a species. This would essentially mean that a species would not be able to adapt to an issue that could arise in the future, meaning that its species could potentially become extinct due to climate change or other arising events.
Discussion: The results acquired from the experiment have supported the hypothesis. In the first sample, red blood cell in the isotonic solution (NaCl 0.85%) kept its regular shape. This is because when RBC was placed in an isotonic solution, which is the solution has the same concentration of solutes as the cell, water will move into and out of the cell simultaneously and no net effect will be seen. In the second sample, cell shrank, and crenation occurred in the hypertonic solution (NaCl 10%) because the hypotonic solution has a higher osmosis pressure than the cell, water is going to escape from the cell for decreasing the high concentration of solute in the hypotonic solution. Lastly, in the hypertonic solution (NaCl 10%), cell bloated,
One of the most common sensations in all humans is that of stress. This may be induced by everything from more serious life-or-death situations, to more mundane concern over deadlines or relationships. The body has a somewhat graded response to these events depending on their severity, but its response, regardless of severity, is rooted in the same neuroendocrine response of the hypothalamic-pituitary-adrenal axis (HPA Axis). This response is characterized by the feedback interactions and influencing of three of the bodies endocrine glands: the hypothalamus, the pituitary gland, and the adrenal glands (1). In response to stress, the hypothalamus releases corticotropin-releasing factor (CRF), which travels through the hypophyseal portal system
Meiosis, or reductional division, is the process during which exchange of genetic material between the homolog chromosomes (crossing-over and recombination) takes place and such a division of the genetical material occurs the four daughercells.
Egg Albumen Experiment The purpose of this investigation is to establish which is the lowest concentration of Copper (II) Sulphate solution that will denature a sample of egg albumen (egg white) at room temperature. The base of the reaction is the globular protein (albumen) being denatured by a heavy metal (Copper (II)), the copper (II) reacts with the NH3 group causing it to denature, this means the proteins' secondary and tertiary structures are being altered and refolding into different shapes, this resulting in a change from the substance being clear to turning opaque.[1] As the concentration of the denaturants increases more folding and changing of shape will occur and therefore more denaturing will occur and at a faster rate. From this I can predict that that lowest concentration of the solution is approximately at 0.03m solution.
The aim of the experiment is to better understand the process and stages of mitosis. Prepare specimens of onion root in order to visualize all stages of mitosis, and estimate the relative length of each stage of mitosis.
In Figure 3-2 and 3-3, the system stabilizes the temperature and humidity to its maintaining value by controlling the incandescent bulb on or off. According to the design standard which is the American Standard of Perfection is the standard of temperature inside the incubator wherein the detailed information is shown in Appendix F. The egg turner will automatically be turned three times a day, as part of design standard American Standard of Perfection (see detailed standard shown in appendix F). The egg candling is done once the eggs is on its 1st, 9th and 18th day, throughout the candling process the user can view what is inside the incubator using the live preview from the IP Camera. While viewing the insides of t...
