The native plants Kelp is important because it provides shelter and food for a lot of sea creatures. Kelp is also used by humans for many products, including toothpaste and ice cream. Kelp also serves as a buffer by absorbing energy from waves before the waves hit the shoreline, protecting many of the sandy beaches along the California coast. Phytoplankton is tiny plant that serves as food for many of the ocean creatures from the smallest of fish to large whales. Some scientists estimate that phytoplankton provide the earth with almost half of its oxygen.
in nature, the bacteria can transfer these plasmids from bacteria to bacteria, transfering those beneficial genes. this mechanism allows bacteria to adapt to new and foreign environments. the continuous resistance of bacteria to antibiotics is due to the transmission of these plasmids. Bio-Rads unique pGLO plasmid encodes the gene for GFP and a gene for resistance the antibiotic ampicillin. pGLO can also control the gene expression of this fluorecent protein.
This is one of the main pieces of evidence used to support endosymbiosis. Take the Paramecium bursaria for example. This single-celled eukaryote demonstrates how easily organisms can become dependent on one another for survival, resulting in a permanent relationship. It does not possess its own chloroplasts and must swallow photosynthetic green algae in order to “borrow” these organelles. Paramecium bursaria chauffeurs the algae and in return, the algae shares the food it produces (Palmer).
Abstract The purpose of this experiment was to investigate if Artemia salina is a good bioindicator for toxins in their environment used to detect pollution. Brine shrimp have a high tolerance for changes in their environment. Shrimp were exposed to varying concentrations of ethanol to test their tolerance level and determine the viability for the crustaceans. Four petri dishes of each concentration were used, as well as four dishes of a control that only contained brine water. Three hundred brine shrimp were placed in each petri dish for each of the controls and ethanol concentrations.
The sea urchins are used by Biologists to unlock the mysteries of human diseases such as cancer. When you compare humans to sea urchins, quite a few amino acid
Week 5 – Assignment 3: Argumentation – Persuasion Essay Richard Miller South University Online Pollution and the Chesapeake Bay The beautiful waters of the Maryland Chesapeake Bay have many valuable assets. For hundreds of years people have used this body of water for recreational, economic, and commercial gain. As seen firsthand, over the last 35 years the Maryland Chesapeake bay is in dire needs of pollution restrictions and clean-up primarily in the bay’s tributaries. Though many people may not realize, the Bay is the Nation’s largest enclosed body of water with multiple fresh water streams feeding it. It is also the nation’s most productive estuary ( Zynjuk, 1995).
A clean house can prevent infestations of disease-carrying vermin, such as rodents, cockroaches, fleas and lice. In addition, making sure your bathroom is sanitary can prevent the spread of dangerous viruses, such as hepatitis A, which can be spread through contact with fecal matter, according to the CDC. Merriam-Webster's Medical Dictionary defines hygiene as practices conducive to health. This includes taking care of your body, maintaining good oral health and eliminating odors. The Department of Health in the Philippines explains that poor personal hygiene can cause skin diseases and worm infestations, diarrheal diseases and dental diseases.
They are a source of protection for small organisms. They also help because their roots filter nutrients that flow from the land into the ocean, and produce the amount of erosion that occurs. This is influential, especially to coral reefs, because it is reducing the amount of nutrients, preventing the production of algae blooms that block the much needed sunlight. Mangroves can significantly slow the wind forces down along the coasts before they reach land, making them a strong defense against hurricane winds, tsunamis, and tornadoes. There are different types of mangroves; red, white, and black.
Report on Effect of Fluorination in Drug Molecules - by Ravinder Singh (MS10103) Introduction Fluorine is one the elements which is abundant in the biological cycles. It's in site can be viewed by its presence in teeth's enamel, ash of blood and also marks its presence the yolk and shell of eggs. Presence of fluorine in toothpastes is a famous for its prevention from tooth decay. Intake of fluorine in trace amounts in the form of food , drinks , medicinal drugs plays a vital role in many biological activities and prevention of many diseases/harms to human body. In the synthesis of drug molecules, fluorine is one of the preferred atom/group because of many desirable qualities it gives the target moiety.
What is the Ecological Footprint? The Ecological Footprint is a resource accounting tool that measures how much biologically productive land and sea is used by a given population or activity, and compares this to how much land and sea is available. Productive land and sea areas support human demands for food, fiber, timber, energy, and space for infrastructure. These areas also absorb the waste products from the human economy. The Ecological Footprint measures the sum of these areas, wherever they physically occur on the planet.
