The results in this lab for Interphase had twenty cells, Prophase had ten cells, Metaphase had three cells, Anaphase has two and last Telophase, which had only one cell. The results shows that Interphase took the longest for completion and Prophase was the second longest for completion. Telophase took the shortest time for completion. The percentages for each mitosis stage and Interphase was fifty-six percent for Interphase, twenty-eight percent for Prophase, eight percent for Metaphase, six…

The model shown in this essay is a representation of meiosis one and meiosis two. The guided question I answered was how does the process of meiosis reduce the number of chromosomes in a reproductive cell? It is important for scientists to answer this question because they need to learn how a reduction in chromosomes is very critical. Without it the two gametes during fertilization, the offspring would result in with two times the regular number of chromosomes. Scientist use models to…

One debate that scientists have pushed and pulled upon ever since the study of virology began, is whether or not viruses should be classified as a living organism or not. Living things are highly organized, and have may other characteristics that accompany it. The general agreement among scientists is that there are seven main characteristics of life; cellular organization, metabolism and energy use, response to stimuli, regulation and homeostasis, growth and development, evolution, and…

At the end of the lab, there were several different Chromaseratops offspring. It is like that because of meiosis. That process creates the cells and gives them chromosomes which become homologous pairs. From there, you can make a lot of different combinations of gametes. For this lab, there was 8 different gametes since there was 3 homologous pairs. For a human there would be way more combinations since we have 23 pairs or 46 chromosomes. Through independent assortment, you receive 2 homologous…

Cells are extremely small, but vital to life and although they are extremely complex they have a common structure that enables different cells to perform different jobs. Cells make up every living organism. Mitochondria are a very important part of the cell because the mitochondria are what provide the cell with energy. In fact, a recent study by Boengler, Kosiol, Mayr, Schulz, and Rohrbach (2017) found “A decline in mitochondrial content and mitochondrial function plays a major role in…

Evan Meyer Professor Nolan Biology 104:14 1/19/18 Journey Through a Cell Eukaryotic cells have one thing in common that is a nucleus and organelles enclosed by a plasma membrane. The cells are found in a variety of living things including animals, plants, fungi, and protozoa. Inside the cells, the nucleus and the organelles perform distinct functions to keep the cell alive as well as meeting its purpose. One cannot imagine how the complex unit of life can feed, replicate, and perform its…

A dichotomous key and observation can be useful tools in identifying microorganism’s taxonomy as a mold, yeast or bacteria. Microbes can be found everywhere in cold, warm, moist or dry environments and molds, yeast and bacteria each have unique characteristics that set them apart from one another and allow them to survive in these environments. Through macro and microscopic observation, different microbes can be observed through the natural liquid and solid phases and be made into slides to be…

Genes are what parent passes on to their off spring. The reason that the off spring don’t look identical to the parent is due to a process called crossing over during meiosis.. Meiosis creates new cells that contain different data than that of the parent due to the genes getting shuffled around by cross linking. The chromatids which are parts of the chromosome cross over bits of data making the new cell unique from the parental chromosome. Dividing this way will ensure that the genes will be…

Mitosis & Meiosis are the two major cell division processes. We know that mitosis is used for fulfilling a body’s cell division requirements. However, meiosis is use solely used for one purpose in a human body. It is used for the production of gametes cells, also known as the sex cells. Mitosis and meiosis are quite similar in processes with very few differences. One of the differences is that mitosis has one division whereas there are two divisions in meiosis. This is the reason meiosis is also…

Ancient Greek debated whether living organisms were composed of endlessly divisible fluid or indivisible subunits. However, this debate was settled and closed with the invention of the microscope which is the required material to understand and observe cells. Let us begin with the ABC’s of the Cell Theory which splits into 3 major parts: All living beings are made up of cells Cells are the basic unit of structure in all organisms All cells come from preexisting cells. To have a deeper…
