3. The earthworm has a segmented body with a mouth at the anterior end and an anus at the posterior end. It has a smooth, purple dorsal side and a rough, yellow ventral side with setae. Two sperm grooves run along the body from segment 15 (where sperm ducts are also located) to the clitellum, which looks like a tube surrounding the earthworm’s body and is closer to the anterior end. 4. The setae are likely on the outside of the body for more effective locomotion. They allow the earthworm to…

This lab report is over the effects of acid rain on plant germination and growth. Testing was done to see the acid rain had an effect on the radish seed germination and growth of the radish plant. Radish plants, also known as raphanus sativus, a cultigen plants. This means that the radishes have become what they are now, due to selective breeding over the course of thousands of years. “Grown worldwide for its fleshy, edible taproot, radish is thought to have originated in the eastern…

organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes. The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. c-Chloroplasts are larger than…

Darwin’s research explored one the fundamental process, known as Natural Selection. Natural selection is the process in which those with the beneficial characteristics that increases it survival rate within a species will move on and reproduce, passing on DNA to the next generation (Natural Selection: Charles Darwin & Alfred Russel Wallace, n.d.). All the beneficial features will accumulate over times and eventually, the result will be a new organism (Darwin’s Theory of Evolution – A Theory in…

In scenario you determine different parts of Forensic Science such as Entomology, Odontology, Anthropology, Pathology, and the Microbiology methods to complete the crime investigation. In the test center, forensic biologists scrutinize this proof using microscopes as well as additional machinery. Introduction Forensic Biologist are used in crime scenes to determine the outcome of scene. They also use Forensic Entomology, Odontology, Anthropology, Pathology, and microbiology…

I agree with the theory of evolution because there are many evidence for it. The evidence includes fossil record, species distributions, vertebrate development process and fossil layers and so on. First, fossil is very important for understanding biological evolution. It can tell us how the living creature evolved. Second, it is species distributions. According to theory of continental drift, it found out many similar fossils even in the place oversea. Third is vertebrate development process,…

Siqi Li May 2015 What topics will students address during the beginning of the school year in Buffalo? During the beginning of the school year in Buffalo, students will study two parts of Living Environment in 7 weeks. The main topic is about the introduction to the course includes the cell which is the foundation of the study of all living things. The key idea 1 in curriculum, living things are both similar and different from each other from nonliving things. The enduring understanding is…

Introduction & Biological Background Animal meat has been a primary source of protein for humans since the beginning of time, yet with an increase in technology and biological knowledge – scientists have been able to create meat without the killing of animals. The ‘victimless-meat’ as it is commonly referred to, is in fact in-vitro, meaning that it has been created in a laboratory. In-Vitro meat is cultured from the stem cells of eukaryotes most commonly derived in the blood drawn from an…

Doctors of today have advanced tools and technology to look at an embryo and tell if it is healthy and ready for life. Many mothers experience complication in pregnancy that can lead to a child being born with disabilities. As stated in JUSTIFYING INFANTICIDE AND NON-VOLUNTARY EUTHANASIA By Peter Singer, infants can be born with “irreversible intellectual disabilities, will never be rational, self-conscious beings.” With the knowledge of the child’s health before birth it gives a morally…

chromosome, one from the mother and the other from the father, strawberries like most fruits are polyploidy, consisting of more than two copies of the same gene. Strawberries are octoploid that have eight copies of each gene, making it an ideal fruit for DNA extraction. Frozen strawberries are ideal because the ice in the intracellular fluid causes the cell to lyse and expand, destroying the cell and nucleus membrane of the cell. Strawberries are soft and easy to crush using a mortar and pestle.…
