Include at least four examples. Natural selection means the process in which life forms by having traits that enables them to adapt to their environment. There are many examples of direct evidence in support of the theory of natural selection. (www.Ask.com). A few of those examples includes: Humans, findings of fossil records, record finding of changes in existing species, and biochemical and anatomical similarities.
“Sea Urchins Reveal Medical Mysteries” By Cristina Calenstani This article,” Sea Urchins Reveal Medical Mysteries” by Cristina Calenstani from Science Daily informs us about how sea urchins contain the same kind of genetics found in humans. This article falls into the category of evolution and genetics in biology. This article on sea urchins also include how these similar genetics can be used to inform us more about Alzheimer’s disease, Parkinson’s disease, cancer, and muscular dystrophy. “ Sea Urchins Reveal Medical Mysteries” discuss how sea urchins and humans share over 7,000 of the same genetics. The sea urchins are used by Biologists to unlock the mysteries of human diseases such as cancer.
MEMO To: Carrie Johnson From: Staff Biologist RE: Bacteria The first step in identifying the mystery organism is to know what kingdom it belongs to. It will belong to one of the following kingdoms: animals, plants, archaebacteria, eubacteria, fungi, or protista. Organisms are placed into these categories based on similarities or common characteristics. Some of the characteristics that are used to determine placement are cell type, metabolism, and reproduction. Examine your living organism and determine if it is a bacteria, achaean or a eukaryote.
6. Biological Psychology is the study of biological bases of psychological processes and behavior. Historical development of biological psychology, is explained by the fact that humans as well as animals can change according to environment, this is important in order to understand just how biology and psychology go together. This is an understanding that dates back to the ancient Greeks. Plato was the one that proposed that it was the brain that was indeed the organ of all reasoning.
Researchers have carefully examined the bones of the fins for dolphins. They found that they resemble the limbs of many animals on land. Dolphins have spines that move up and down opposed to
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
The seven organizational approaches Tonya Rutherford HCA/220 October 21, 2012 Diane Kondas The seven organizational approaches There are seven organizational approaches to studying the human body. Each approach is very important in getting a better understanding on how the human body works. The seven organizational approaches are Body plane sand directions, Body cavities, Quadrants and regions, Anatomy and physiology, Microscopic-to-macroscopic, Body systems, and Medical specialty. In addition to these approaches being important in the complexity in understanding of the human body they can be useful in the health care field as well. Body planes and direction approach is the division of the body into sections from front to back, right and left and top to bottom via the midsagittal plane, the coral plane, and the transverse plane.
Once one realizes that psychology is a branch of biology, inferential tools developed in biology -- its theories, principles, and observations -- can be used to understand psychology. Here are five basic principles -- all drawn from biology -- that EPs apply in their attempts to understand the design of the human mind. The Five Principles can be applied to any topic in psychology. They organize observations in a way that allows one to see connections between areas as seemingly diverse as vision, reasoning, and sexuality. Principle 1.
Geo 202 Ichthyosaurs Ichthyosaurs, the Greek word for fish lizard, were a marine animal far from what its name implies. They played the role of what whales, seals, and dolphins play in today’s marine ecosystem. From fossil records, geologists can tell a lot about the life ichthyosaurs lived throughout the years it roamed the seas, including their body structure, how they reproduced, what they ate, where they lived, and much more including their extinction. Based on fossil evidence, the ichthyosaur first appeared around 245 million years ago. Although earlier forms had a sleek, lizard like body, most had a body structure that most resembled modern day mammals (Perkins).
While swimming up or down through the water, the nautilus uses its siphuncle to suck in fluid or draw it out, allowing it to adjust its overall buoyancy. Comparison of Anatomy of Ammonites and Nautilus Despite the fact that the Ammonites and Nautilus may appear the same, they are easily distinguished by notable location and function of their anatomical features. Siphuncle According to the University of California Museum of Paleontology, the siphuncle is an internal tube that runs through and connects the chambers of the shell. This tube is used for expelling water and gases as the shell grows or decrease the density of the animal’s interior so that it floats upward. In Ammonites, siphuncle is found along the shell’s outer edge, while in Nautilus it runs through the center of the shell chambers, as shown in figure
