Similarities from the yolk stages of many organisms make it easy for scientists to relate their research to other organisms for stronger results. “The fish, amphibian, and chicken embryos were like nothing I had ever seen before in biology. They all looked generally alike” (98). Knowing how similar these organisms are in the yolk stages helps scientists understand the differences in the development of these organisms. The yolk stages really define how a-like these organisms are and how we have a inner-fish, inner-frog, inner-anything.…
Level 3 Applied Science Unit 11 physiology of Human Body Systems Task 1: ORGANELLE DIAGRAM FORM FUNCTION Nucleolus • The nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell.…

Competition 1. Below are two types of organisms that compete. Explain what each is fighting for and the strategies employed to dominate. a. Corals- Compete for Sunlight i. Staghorn coral – grow fast and rise above the competition ii.…
Rhabdomyosarcoma, also know as RMS, is a type of sarcoma in which cancer cells form a muscle tissue. There are three main types this disease has, Embryonal, Alveolar, and Anaplastic. There is also stage I, stage II, stage III, and stage IV. There are treatments for RMS but it's all depending on the area, type, and stage of the cancer, survival rates will also fall under that.…
There are many organelles in the animal cell. There is the nucleus, endoplasmic reticulum, cell membrane, vacuoles, lysosomes, mitochondria, cytoplasm, ribosomes, & golgi apparatus. The nucleus directs all the cells activities,including reproduction. Endoplasmic Reticulum is a network of membranous tubules within the cytoplasm continuous with the nuclear membrane;It usually has ribosomes attached The cell membrane protects the cell and regulates what substances can enter and leave. Some animal cells have vacuoles that store food, water, & waste.…
The Effects of Temperature on Cellular Membranes Kean University: Biology 1300 Section 3 Liyet Iran Partners: Paoline Medina, Jennifer Yuen, Christian Gonzalez, D’wan McCrary, Nicole Piscatelli November 12, 2015 Abstract The cell membrane is an essential structure of any cell. It’s the structure that protects and support the cell. To determine whether this structure can withstand hot or cold environment, a beet specimen is put to test. Six consistent cylindrical beet will each be placed into different temperatures ranging from -5℃ to 70℃.…

Question 1. a) “What serosal cavities have been penetrated by the 1st arrow?” The pleural cavity and pericardial cavity have been penetrated by the 1st arrow as they tend to appear in the thoracic cavity on the left side of the chest. b) “Explain the location, the microscopic characteristics of the serous membrane, and the purpose of the serous membrane.”…
By the fifth week been compressed and formed what we know as the umbilical cord. The umbilical cord has two arteries that carry blood from the embryo to the chorionic villi and there is one vein that returns the blood to the embryo. At birth, the infant is still attached via the umbilical cord, which is part of the placenta, to the mother. The placenta continues providing oxygen, red blood cells, stem cells, immune cells and blood volume to the neonate. In a term newborn the blood volume can range from 80 to 100 mL/kg of the newborns total body weight.…
To be brave is to be bold and courageous. In Aldous Huxley’s world of consumerism, there are new morals, new standards, and new values. All of these aspects contribute to form the World State, whose beliefs are to maintain “Community, Identity, and Stability.” Huxley had a world of his own to observe different ideas and beliefs in order to create his Brave New World.…
In 1954, a british scientist named J. B. Haldane created the phase ¨ectogenesis¨ to describe how human pregnancy would one day give way to artificial womb. Ectogenesis is defined as ¨the development of embryos in artificial conditions outside the uterus.¨ 14 years ago in 2003 a embryo of a mouse almost made it to full term and was reported to be moving around and breathing in an endometrial tissue , but died just a few days later. Endometrial tissue is defined as ¨ the mucous membrane that lines the uterus.¨ Recently a team of researchers successfully grew a premature lamb within an artificial womb.(Davis, parag 1). The controversy over the artificial womb has people arguing with the idea whether or not the artificial is a good idea or it is not a good idea .…
“Fetuses do not have rights, pregnant women do” Ari Armstrong. One can say that the controversies about the rights of a fetus are amongst believers and non-believers. Believers of God state that He does everything for a reason and that the second a fetus is conceived then it has a right to life. Whereas non-believers think otherwise, they view the world in a scientific perspective and take into consideration the stages/periods of a fetus as well as the pregnant women herself. There are exactly three periods in the prenatal development: the germinal period, the embryonic period, and the fetal period.…
1.1 Describe stages of development from conception to birth. When an egg is fertilised it is a single cell called a Zygote, in the next 24-36 hours the single cell will divide into two cells, 12 hours after it will divide into four cells, and will carry on dividing which forms a cluster of cells which are called a monula. Three – four days after it has been fertilised the monula will move from the fallopian tube and will enter the uterus. At about six days the monula will form a hollow cavity which is known as a blastocyst. The blastocyst will burrow itself into the uterus lining this is called implantation.…
This subject will give prospective parents a fundamental knowledge of the physical and biological changes that their children, both unborn and growing, will experience over time. Undoubtedly, life begins at the moment of conception; therefore, parents’ knowledge of the different life spans, from the Pre-natal to adult stage, could be a vital factor of their children’s overall growth and functions in the society. Let us imagine a situation where a mother is uninformed about the impacts of certain harmful substances, (teratogens), on her unborn child. She smokes cigarettes, drinks alcohol, and is generally lackadaisical about the substances that the fetus feeds on.…
