Cell cycle

The egg is an example of an animal cell that is placed in environments of different tonicity. The vinegar was used to dissolve the shell so that we can see the effects when we placed the egg either in a hypertonic or hypotonic solution. Since the egg membrane is semipermeable similar to the cell membrane, it only allows specific substances to pass in and out of the egg membrane down its concentration gradient. In this case, we are trying to measure to the diffusion of water that goes in and out…

Initiative as combinations of technology begin to emerge (Bargmann BRAIN 2025). An example of this combination of technology is when scientists combing advance genetic and optical techniques, it allows them to use pulses of light to determine how specific cell activities in the brain affect behavior (The BRAIN). Animal research technologies that are BRAIN-supported will inspire next-generation devices for human brain monitoring and therapies using optical, acoustic and magnetic modalities…

In a new article published in the New York Times, a study was conducted that proves that children who are born from older fathers have a higher risk of getting a mental illness, compared to their siblings. These mental illnesses include schizophrenia, bipolar disorder, and autism (Carey 2014). The study was conducted in Sweden since they keep good track of their medical records. This made it easier for researchers to look at siblings and see if the age of the father had any correlation with…

Technology has advanced so far that it has created new opportunities for parents to genetically modify their offspring. This new technology allows parents to choose their desired traits such as the offspring’s gender, eye color, handedness, addictive behavior, nutritional background and athleticism. Many people refer to this new technology as designer babies. This name is termed by many journalists because its purpose is to give more control to parents over their child’s genes before they are…

Introduction Perhaps the most controversial principle of biology, this is due to many reasons ranging from the ignorance of the population to religious beliefs. I have chosen this principle as I wish to portray an unbiased look at this bold claim made by scientists where I present the facts in a scientific manner. So is there really any evidence that claim is true? Of course, we cannot tackle the entire tree of life at once, so instead, we’ll focus most of our attention on one small but…

The world is full of amazing influences that help shape our society and mold our future. The littlest things in nature could cause some of the best inventions. Technologies like Velcro, adhesives, and spider web glass have been created from bio mimicry, or innovations inspired by nature. Even something as simple as a butterfly could hold the key to breakthroughs in medical science. A very iconic butterfly known as the Blue Morpho could play a vital role in today’s advancements. It is renowned…

This could also lead to evolution, survival of the fittest, overpopulation and the extinction of others. Limiting factors can be many things like space, food, light and many other things. For Sunflowers and example that would lead to carrying capacity would be if all the organisms that consumed or killed the plant would be removed from its environment by an invasive species or environmental changes, then the Sunflowers would grow faster and closer to each other. This would cause space, water,…

more similar than MZA twins. They are called monozygotic twins because they start as a fertilized egg, called a zygote, and then split into two identical embryos. Fraternal twins are the result of two separate eggs fertilized by two separate sperm cells and are referred to as dizygotic twins.…

your body that renew and generate every day, weeks and years. The first three body part that stays and develop through time are our hearts, lens and neurons. Half of our heart remain the same since you were born because the process to replace these cells takes a very long time. Lens, its core remains the same since the first day you were born but the same but it stretches and adds a few more transparent protein. Neurons in some certain parts of your brain shaped when you were born and develop…

Maria Carranza Mr. Krone Chemistry 11 February 2016 Which is the Best Contact Solution? Everybody know someone who has glasses and contacts, maybe it’s your friend, your mom or dad or maybe a sibling, but does one really know what is going on in that contact case? Maybe one has daily's or maybe to change every month when one open that new package of contacts, does one really know how long that solution stays good? Does anyone? Let’s talk about your eyes. In the essay, the writer shows you…
