Light years away in a distant galaxy, there is a planet. Not a planet anything like our own, but much larger, approximately eleven times larger than our own making, it is closer in size to that of Jupiter. The name of this planet is Kronos. Since Kronos is so much larger than our Earth it has an atmosphere that is very close to the surface of the planet, this is true because the law of universal gravitation tells us that as the masses of two objects increase the distance between the two objects decreases. This atmosphere unlike Earth’s has mostly methane and nitrogen at around 46% methane and 52% nitrogen abundance. Since the atmosphere is so close to the surface the surface of Kronos is under a lot of pressure because

For now we will be focused on how the Xyrillian are able to flourish on such an inhospitable planet. The organ systems that will be discussed are the digestive, integumentary, and cardiovascular. To start I will go over how the Xyrillian obtain their nutrition and how it is transported through the body and into the digestive system. You may be asking yourself “What do these things eat if there are no organic life forms other than themselves?”, well the Xyrillian do not eat like humans, they due to lack of food sources, have developed a form of nitrogen fixation chemiosmosis. For this part refer to the diagram of the Xyrillian anatomy, as you will see on the skin between the scales there are pores. These pores are capable of taking in atmospheric nitrogen and methane then converting the nitrogen into ammonia (nitrogen fixation), once this is complete the ammonia is combined with the atmospheric methane to make methylamine (chemiosmosis). Methylamine is an organic nitrogen based compound and the main source of energy for the Xyrillian. Once the methylamine is made, it is stored in the storage cavities below the scales on the epidermis of the skin. Once the storage cavities have reached maximum capacity the methylamine is released into the veins of the circulatory system where the returning blood flow will filter through the heart and the methylamine will be sorted out and stored in the lower section of the heart called the storage ventricle. So not only does the heart control blood flow and nitrogenation of the blood, but it also is responsible for the collection and storage of the body’s food source. From the storage ventricle the methylamine is pumped by the heart into the stomach where it is broken down using mechanical (smashing) and chemical (Nitric acid) methods. Once the methylamine has
Thyroid and metabolism hormones play a large role in the daily lives of all living species. Thyroid hormones regulate the metabolism and the metabolism is responsible for maintaining a specific range for the biochemical reactions that occur in the body (Martini 2014). The most important hormone for metabolic maintenance is thyroxine (T4). This hormone also plays a large role in body heat regulation. It is produced by the pituitary gland and secreted by the thyroid gland. The thyroid releasing hormone (TRH) must trigger the thyroid stimulating hormones (TSH) to release thyroid hormones to the thyroid gland. These hormones are under control of the hypothalamus, or main neural control center. Propylthiouracil (PTU) is a medication used to treat
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.

Have you ever looked up into the night skies and wondered what might be out there? One question I always wonder is where in the universe might there be a livable planet? Well the answer might be closer than you think, well actually 588 million kilometers away from earth. Jupiter of course is what I’m talking about. Fell first let’s ask the why we might move. Let’s face it earth is not going to be able to be habitable forever in fact ate the rate humans are polluting the atmosphere earth won’t be around that much longer. So might need a new place to live. So could the answer be Jupiter? Before that we need to know a little about the new planet and if it’s able to sustain life. Let’s start with the Jupiter’s history. Jupiter is the largest planet in the solar system. Jupiter was named after the king of the gods and Roman mythology. The ancient Greeks named the planet after Zeus, the king of the Greek pantheon. In 1610, a man that goes by the name “Galileo Galilei” was looking through his homemade telescope when he came across Jupiter. He notice four objects circling Jupiter and described them as "four fixed stars, totally invisible by their smallness" it was there were he discovered four large moons Io, Europa, Ganymede and Callisto, which underwent several name change but are now known as the Galilean moons. This was the first time celestial bodies were seen circling an object other then Earth. Jupiter spins faster than any other planet, taking 10 hours to complete a turn on its axis, compared to that of 24 hours for Earth. This rapid spin makes Jupiter bulge at the equator and flatten at the poles, making the planet about 7 percent wider at the equator than at the poles. This is Jupiter and this is Jupiter next to the earth. Jup...
The atmosphere of Uranus is thick with a lot of hydrogen, helium, and methane. It has a very low density, the mean density is 1271 kg/m³. Uranus lacks any really significant internal heat source and it mean surface temperature is 58° K.
The rapid pace of vaccine development convinces people that they are safe from the infectious diseases. Unfortunately, the anthrax outbreak in 2001, having killed five people, reveals the vulnerability of the public health, suggesting that further research on contagious epidemics should be developed abruptly. In response to this issue, the National Institute of Allergy and Infectious Diseases (NIAID) granted Boston University a $128 million funding for the construction of a new leading facility known as the National Emerging Infectious Diseases Laboratory (NEIDL or BU Biolab), which would be sited on the Boston University Medical Campus, to battle against contagious ailments. Besides conducting research on infectious diseases, the BU Biolab will also perform research to prepare for bioterrorism (Le Duc). According to the Center for Disease Control, there are four levels of increasing of containment for research on infections ranging from Biosafety Levels 1 through 4 (BSL-1 to BSL-4). While much of the research on epidemics is done in laboratories with BSL-2 to BSL-3, the BU Biolab, with the highest level of precaution, BSL-4, will conduct research on rare contagious epidemics including anthrax, ebola, and plague, which are usually life threatening.
Biology literally means "the study of life". Biology is such a broad field, covering the minute workings of chemical machines inside our cells, to broad scale concepts of ecosystems and global climate change. Biologists study intimate details of the human brain, the composition of our genes, and even the functioning of our reproductive system. Biologists recently all but completed the deciphering of the human genome, the sequence of deoxyribonucleic acid (DNA) bases that may determine much of our innate capabilities and predispositions to certain forms of behavior and illnesses. DNA sequences have played major roles in criminal cases (O.J. Simpson, as well as the reversal of death penalties for many wrongfully convicted individuals), as well as the impeachment of President Clinton (the stain at least did not lie). We are bombarded with headlines about possible health risks from favorite foods (Chinese, Mexican, hamburgers, etc.) as well as the potential benefits of eating other foods such as cooked tomatoes. Informercials tout the benefits of metabolism-adjusting drugs for weight loss. Many Americans are turning to herbal remedies to ease arthritis pain, improve memory, as well as improve our moods. Can a biology book give you the answers to these questions? No, but it will enable you learn how to sift through the biases of investigators, the press, and others in a quest to critically evaluate the question. To be honest, five years after you are through with this class it is doubtful you would remember all the details of meatbolism. However, you will know where to look and maybe a little about the process of science that will allow you to make an informed decision. Will you be a scientist? Yes, in a way. You may not be formally trained as a science major, but you can think critically, solve problems, and have some idea about what science can and cannoit do. I hope you will be able to tell the shoe from the shinola.
them. They were able to sustain their survival from the living plants and animals that lived among
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.
In Ap biology, we were handed a Campbell Textbook before the class began in order to complete the pre-modules. I consider the textbook to be the most beneficial resource that we had during this course, due to the amount of detail, examples, and images that it contained explaining each concepts in a reliable way. The power points that were made to summarize the main points from the textbook were helpful, however they were really long and made me miss what was actually important and take additional notes on filler information. Due to the long powerpoints, I felt implied to take long and details notes, which people struggled in this class, either taking too much or too less. After two units passed, we were taught how our notes should be, which will later help us in college. This strategy allowed me to understand the important information and identify the filler information, resulting in
The earthworm digestive system is one of the simplest digestive systems compared to the frog or a human. The digestive system is section off into certain parts and each part has a certain function in the digestive process. The earthworm’s digestive system consists of the pharynx, the esophagus, crop, the intestine, and the gizzard. Each organ has a specific contribution to the digestion in an earthworm. The food, which is usually soil, passes through the mouth and is swallowed into the digestive system through the pharynx. Then, the soil passes down the esophagus which has enzymes that help to rid the earthworm’s body of extra calcium that...

A star begins as nothing more than a very light distribution of interstellar gases and dust particles over a distance of a few dozen lightyears. Although there is extremely low pressure existing between stars, this distribution of gas exists instead of a true vacuum. If the density of gas becomes larger than .1 particles per cubic centimeter, the interstellar gas grows unstable. Any small deviation in density, and because it is impossible to have a perfectly even distribution in these clouds this is something that will naturally occur, and the area begins to contract. This happens because between about .1 and 1 particles per cubic centimeter, pressure gains an inverse relationship with density. This causes internal pressure to decrease with increasing density, which because of the higher external pressure, causes the density to continue to increase. This causes the gas in the interstellar medium to spontaneously collect into denser clouds. The denser clouds will contain molecular hydrogen (H2) and interstellar dust particles including carbon compounds, silicates, and small impure ice crystals. Also, within these clouds, there are 2 types of zones. There are H I zones, which contain neutral hydrogen and often have a temperature around 100 Kelvin (K), and there are H II zones, which contain ionized hydrogen and have a temperature around 10,000 K. The ionized hydrogen absorbs ultraviolet light from it’s environment and retransmits it as visible and infrared light. These clouds, visible to the human eye, have been named nebulae. The density in these nebulae is usually about 10 atoms per cubic centimeter. In brighter nebulae, there exists densities of up to several thousand atoms per cubic centimete...
Perhaps one of the most interesting features of our fathomless universe are the planets that are classified as gas giants. Huge, turbulent, and distant, the gas giants are some of the most enigmatic features in our Solar System. I have a personal interest to the gas giants and celestial bodies in general. When I was a child, I was fascinated by our Solar System. I read innumerable books about space, and my interests of outer space had been piqued further by other forms of media. Although I held this interest of space, growing up left me with little time to learn about space, and I lost interest for a while. Taking Earth Science in Milpitas High re-invigorated my interests in the celestial bodies. Using this class, I’m now able to focus on learning more about our colossal universe, in particular, the outer planets.
Our knowledge gained of Titan has drastically improved since the early 1980s when Voyager flew past it. Titan is Saturn’s largest moon and the second largest moon of our solar system. It has a diameter estimated roughly 40% of Earth’s moon (Titan’s Radius: 2576, Moon’s Radius: 1737) and is 80% more massive (Titan’s Mass: 1.35 x 10^23 kg, Moon’s Mass: 7.35 x 10^22 kg. Titan has a atmospheric surface pressure 50% more than of Earth’s. In addition to that, Titan is the only moon to have a dense atmosphere. Titan’s atmosphere has been calculated to be 4.5 times more dense than of Earth’s atmosphere, which can been clearly noted by the layers of haze seen. The atmosphere in Titan is approximately 1.5km and is mainly composed of nitrogen. Titan has a very similar vertical atmospheric structure to earth, Titan has a troposphere temperature of ~94-~70K, a tropopause temperature of 70.4K and a stratosphere temperature of ~70-175K.
