Marine Biology

In chordates, the ventral heart is typically located beneath the pharynx and functions as the main pump for circulating blood throughout the body. It is often found in the lower part of the body, near the anterior end of the animal.

There is no specific exam required for certification in marine biology. However, to practice marine biology professionally, it is recommended to have a relevant degree (at least a bachelor's) and gain experience through internships or research opportunities. Some specialized fields within marine biology may require additional certifications or licenses.

A mussel's byssal threads are produced from within the shell by a byssal gland. They are small proteinaceous "ropes" extending from the muscular foot. Byssal threads are also amazing for the ability to adhere to substrate surfaces underwater.

Long Island Sound can appear green due to the presence of algae blooms, which are made up of microscopic plants that thrive in nutrient-rich waters. These blooms can happen due to factors such as warm water temperatures, sunlight, and high levels of nutrients from sources like agriculture runoff and wastewater.

Epitheliomuscular cells function to provide both epithelial and muscular properties within the organism. They are found in the body walls of some invertebrates, such as flatworms, and help with movement and support by having both contractile muscle fibers and epithelial cell layers for protection.

In animal cells during prophase, the centrioles move to opposite poles of the cell and spindle fibers begin to form. The nuclear membrane also dissolves, allowing the genetic material to interact with the forming spindle fibers.

Carbonic acid forms when carbon dioxide dissolves in water. This acidification of the ocean decreases pH levels because carbonic acid releases hydrogen ions, increasing the acidity of the water. This can have negative impacts on marine life that rely on dissolved calcium carbonate to build their shells and skeletons.

Your body constantly regulates internal function. This is called homeostasis. Part of this process is maintaining a core body temperature of 98.6 degrees F. If you were to jump into water that was 50 degrees F, what reaction would you have? Immediately, you would inhale quickly. This is your body beginning to shiver, which is a natural warming function. Your heart rate will also increase allowing warm blood to be pumped faster to your extremities. Unfortunately, being in 50 degree water for any extended period of time is never recommended, you will exhaust quickly while keeping warm. During infection or hot days, your body temperature may rise. This is a response to certain microbial stimuli or via the hot sun. What does your body do? Well sweating seems like the most common answer. Producing sweat allows you to cool a lot faster. Also, you will notice yourself getting thirstier.

These are just a few examples that cause your body temperature to remain constant.

Excess carbon dioxide in the atmosphere leads to global warming and climate change by trapping heat and altering weather patterns. In the oceans, carbon dioxide is absorbed, causing ocean acidification which harms marine life, especially organisms that rely on calcium carbonate to build their shells or skeletons.

Yes, Sylvia Alice Earle, also known as Dr. Sylvia Earle, is still alive. She is an American marine biologist, oceanographer, and explorer who has made significant contributions to marine conservation and research.

Yes, marine biology jobs are expected to continue being available in 2020 and beyond. The demand for marine biologists is driven by the need to study and preserve marine ecosystems, as well as to address environmental issues related to the oceans. Additionally, advancements in technology and research methods are likely to create new opportunities in the field.

How many hours a marine veterinarian works in a day depend on the facility for which they work. The hours also depend on what is going on in the clinic on a particular day. The standard work day is comprise of 8 hours.

Yes, Carl Chun was married to Margarethe Schmidt. They had several children together.

You must have a strong love for marine environments and be ready to work very hard. The field is very competitive and you must know that marine sciences is what you want to do. Taking marine based classes, swimming, and scuba are a few steps towards becoming a marine biology.

Acidosis can harm marine animals by disrupting their internal pH balance, affecting important biological processes such as enzyme activity and oxygen transport in the blood. This can lead to reduced growth, reproduction, and survival rates in marine animals. Additionally, acidosis can weaken their shells or skeletons, making them more vulnerable to predators and environmental stressors.

Sea anemones are often bottome feeders, eating anything that comes their way. Many species look more like flowers than the animals they are.

Cubozoans, also known as box jellyfish, differ from scyphozoans in having a box-shaped bell and complex eyes. They are more advanced in terms of their nervous system and sensory structures. Compared to other cnidarians, cubozoans have more potent venom and a more potent sting that can be harmful to humans.

cheese nuggets and danishes are mainly what all sharks eat it may sound weird but sharks find many danishes and cheese nuggets since the companies that make them throw out the excess amount of cheese nuggets and danishes when they have made too many.

Marine science draws on traditional science disciplines such as biology, chemistry, physics, and geology. It encompasses the study of marine organisms, ecosystems, ocean chemistry, physical processes, and geological features to understand the marine environment holistically.

Carl Chun was influenced by his mentor and teacher, Ernst Haeckel, who was a prominent marine biologist and zoologist. Haeckel's passion for marine biology inspired and motivated Chun to pursue a career in this field.

It is estimated that around 33% of coral reefs worldwide are degraded or destroyed. The current population of living coral species is difficult to determine as it varies by region and species. However, conservation efforts are being made to protect and restore coral reefs to help increase their population.

Dr. Avril Siung Chang has made important contributions in the field of genetics, particularly in cancer research. She has focused on studying genetic variations that may increase susceptibility to cancer and has worked on identifying potential biomarkers for early detection and personalized treatment of cancer. Additionally, she has also contributed to research on the impact of genetic factors on cancer disparities among different populations.

Protists that obtain food by photosynthesis, like algae, are important for other organisms because they are primary producers at the base of many food chains. They are a source of energy for organisms higher up in the food chain, such as zooplankton and fish. Additionally, they play a crucial role in the production of oxygen through photosynthesis.

Starfish typically mate during the spring and summer months when water temperatures are warmer. This allows for optimal conditions for reproduction and the development of their larvae.

No, marine ecology is a branch of ecology that studies the interactions and relationships between organisms in marine environments. Marine biology, on the other hand, is a broader field that encompasses the study of all living organisms in marine environments, including their behavior, physiology, and genetics.
