    Organelles as organism is from The Lives of a cell authored by Lewis Thomas. Thomas uses a unique writing style that is very recognizable and different from the others. This helps us to appreciate our diversity as human beings demonstrated by our abilities to write differently. As a reader one is able to form an image of who Thomas is by how he expresses his feelings and attitudes. When this text was written a lot of people, mostly scientists, thought and had knowledge of different things than they do now.

    The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.

    2a. If sunlight were to disappear almost completely, it would leave lasting effects on many organisms such as an earthworm, a shark, a maple tree, a saguaro cactus, or a teenager. While looking at an earth worm, the short term effects would be beginning to see more of the species during the day. Earthworms are nocturnal, so they live beneath the surface when it is daylight and come out once the sun goes down. Because of this in the long run, the earthworm species would eventually become overpopulated; they would be above the surface more, so they would have more time to reproduce.

    The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is

The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.

    The small intestine propels the food deeper into the large intestine through the process peristalsis. The pancreas, liver, and gallbladder have different purposes to aid the small intestine while digesting the food. The pancreas produces enzymes which digest carbohydrates, proteins, and fats; the liver produces bile to help break down fats, and finally if extra bile is produced it will end

    Who, what, when, where, why and even how it happened, or the reason you started researching the problem. The second step is research. By researching you start by writing notes down to answer the question or the problem you want to know more about, either by looking through books, magazines, newspapers, and even the Internet. The hypothesis "is really an educated guess about how variables are linked, usually expressed as an if-then statement: if this particular thing were to happen, then that particular thing will result" (Macionis, 2016, Chapter 1.6). The experiment is collecting and researching data to obtain the correct information that follows under the hypothesis.

  • Genotypes In My Family

    707 Words  | 3 Pages

    Heredity is basically the passing on of genetic traits from parents to offspring. Both phenotypes and genotypes are passed down from one’s parents. A genotype is the genetic code of one’s cells. These genetic codes consist of paired alleles and often fall into three categories: homozygous dominant (BB), Homozygous recessive (bb), and Heterozygous (Bb). Phenotypes are the physical expression of genotypes, for example, whether someone has freckles vs. if someone does not have freckles.
