Hydro-international article: Benthos, Inc.
Benthos was founded by Samuel O. Raymond.
He created an innovative company in marine technology which has positively impacted the field for over four decades.
It manufactures a variety of oceanographic equipment, including flotation devices; hydrophones for locating mining sites, tracking boats, and research for marine biology; and modems, which are used to communicate information wirelessly underwater.
For much of the company's lifetime, it supplied underwater equipment to the military, the government, and for research.
Smithsonian Magazine: 14 fun facts about marine bristle worms
Polychaete worms are a diverse class of animals with at least 10,000 species.
They are characterized by a head and a tail, and a pair of bristled "legs", called parapodia, for each segment of their body. They are typically bioluminescent, meaning they have the natural ability to glow.
Due to their effective adaptation, they can live in any marine habitat (including coral reefs, hydrothermal vents, or simply out in the open ocean) and have survived the five mass extinctions since 500 million years ago.
National Ocean Service: What is a bivalve mollusk?
Bivalves are mollusks with a two-part hinged shell to cover a soft invertebrate. They breathe and eat using gills.
Their organ, the mantle, produces calcium carbonate which causes the shell to grow with the organism.
They have important roles of being prey for predators, filtering water, and acting as a habitat in aquatic ecosystems.
These mollusks can live in any of the five oceans, whether it be the frozen Arctic or the hydrothermal vents in the Pacific.
There are over 9000 species.
Marine Education Society of Australasia: Echinoderms
Echinoderms are characterized by radial symmetry, having multiple of five arms, a calcium carbonate shell, and an outer layer of skin that maintains the skeleton.
They are found on the sea floor and include starfish, sea cucumbers and sea urchins.
They have the ability to hunt prey larger than their mouths due to their ability to eat from their stomachs. They detect food through a senstitivty to chemicals, although they lack any brains.
There are over 7000 species.
Thoughtco: Sea Squirts
Sea Squirts, scientifically tunicates or ascidans, are a class in the animal kingdom with over 2000 species.
They were given this name for their ability to contract and squirt water.
They do this using the inhalant and exhalant siphons, which are also used for eating and excreting waste.
They live in subtidal locations while attached to shells, rocks, piers and boat hulls.
Sea Squirts may live in colonies or individually. Colonies are created when they reproduce by budding, or when a new animal grows off of the original.
National Geographic.com: Sea Anemones
Sea anemones are an invertebrate which have stinging and venom-filled tentacles, called polyps, to hunt passing fish.
They tentacles surround a central mouth and inject a paralyzing substance into its prey, before guiding them into the mouth.
Apart from hunting, they also eat leftovers from clownfish, who are immune to the anemone because they are covered with a mucus and live within the polyps.
They live attached to rocks on the seafloor and coral reefs, usually in tropical waters.
There are over 1000 species.
Conclusions or Summary:
The marine technology company Benthos led to the discovery or further information about these animals because it provided equipment to researchers.
All of these organisms are animals and diverse with thousands of species in each of these common names.
They are adaptive and can generally live and thrive in a variety of habitats, whether the difference be in surface material or climate.

What is the real story of Thanksgiving? GIVE A LOT OF DETAIL
Others pinpoint 1637 as the true origin of Thanksgiving, owing to the fact Massachusetts colony governor John Winthrop declared a day of thanks-giving to celebrate colonial soldiers who had just slaughtered 700 Pequot men, women, and children in what is now Mystic, Connecticut.
The famous first Thanksgiving took place in 1621 and involved the Pilgrims, Indians, and a feast. The Pilgrims faced challenges upon arriving in an unknown land but built trust with the indigenous people.
Explanation:The Real Story of ThanksgivingThe famous "first" Thanksgiving took place in September or October, 1621. The Pilgrims had killed a large number of ducks and geese and Massasoit arrived with about one hundred Indians who later killed five deer to add to the feast. The participants ate with their fingers and sprawled on the ground as they consumed the feast. There was no pumpkin pie or cranberry sauce, and no eating utensils except knives.
William Bradford's narrative recounts the challenges faced by the Pilgrims when they arrived in an unknown land. They faced harsh winters and dangerous storms. However, they formed a relationship with the indigenous people, including Squanto, who proved trustworthy and helpful.

Explanation:
According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembrane components, including the nucleus, endoplasmic reticulum and golgi apparatus in what would become eukaryotic cells. The evolution of endomembrane components provided for compartmentalization in eukaryotes, leading to more efficiency in cell processes. The endomembrane system includes the endoplasmic reticulum. Which statement does NOT describe the endoplasmic reticulum (ER)?
A) The ER is an extension of the nuclear envelope.
B) The ER serves as a transport network for the proteins produced in its membrane.
C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.
D) The ER serves a role in protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage
Explanation:
False: C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.
The golgi apparatus comprised of several components called cisternae, these function as different microenvironments, where further modification proteins and lipids into functional biomolecules occurs.
During protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes, the newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Within the golgi body, the proteins are tagged and parceled into lysosomes for export.
Further Explanation:
The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.
Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination. Proteins here undergo peptide processing and glycosylation

Some scientists claim that humans are responsible for the increase of CO2 in the atmosphere. Evaluate which system the increased CO2 levels are likely to affect, and predict the effects of increasing atmospheric CO2 on natural and agricultural ecosystems.
Yes, human activities are a significant cause of the increase in the amount of Carbon dioxide in the atmosphere.
Explanation:The increasing amount of [tex]CO_2[/tex] is a big problem in today's world for the atmosphere. Human activities are playing a vital role in the rise in [tex]CO_2[/tex]. Carbon emission is majorly happening because of pollution. The pollution by vehicle, wax factories, chemical factories, etc. also, some other kinds of Carbon emission activities are there like burning coal and plastic produces Carbon in very high amount and this Carbon directly mix into the atmosphere.
Due to the increase in [tex]CO_2[/tex], both natural and agricultural ecosystems are suffering. [tex]CO_2[/tex] causes air pollution, and because of that, the quality of crops is declining day by day. Also, the natural vegetation is struggling as the rainwater is also not pure; the amount of acidic content in natural rain is increasing per year.

So it is imperative to take some severe legal measures to save the environment and decline the amount of [tex]CO_2[/tex] producing.
The step in photosynthesis where organism capture CO2 in order to convert it into glucose
Explanation:
This step is called Carbon fixation.
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and inorganic carbon dioxide while oxygen (from the light reaction) is released.
Further Explanation:
This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This begins in the thykaloids, where pigment molecules like chlorophyll reside. The chloroplast is a membrane-bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.
Here, water is used as a reducing agent.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
In the Calvin Cycle:
During the initial stage, three molecules of ribulose bisphosphate, RuBP are reduced and carbon is fixed from an inorganic CO2 to an organic form by the enzyme RuBisCO. With every molecule of CO2 fixed, 2 molecules of 3-phosphoglyceric acid are produced. 3-PGA is a 3 carbon molecule with a phosphate attached.
This is called carbon fixation.

The Calvin Cycle or light-independent reactions of photosynthesis is where organisms capture CO2 to convert into glucose. This is accomplished using the enzyme RuBisCO and energy carried by ATP and NADPH. After three cycles, a sugar molecule G3P leaves the cycle to become part of a carbohydrate molecule.
Explanation:The step in photosynthesis where organisms capture CO2 to convert it into glucose is called the Calvin Cycle or light-independent reactions. During these reactions, an enzyme called RuBisCO fixes CO2 from the environment, combining it with an organic compound, RuBP. The resulting six-carbon compound is then broken down into two three-carbon compounds, and the energy in ATP and NADPH is used to convert these molecules into a type of sugar called G3P. After three cycles of the Calvin Cycle, one of the G3P molecules leaves to become part of a carbohydrate molecule such as glucose, while the remaining G3P molecules continue in the cycle to be formed back into RuBP to react with more CO2.

How does water affect metamorphic processes?
A. It decreases the rate at which metamorphic reactions take place.
B. It prevents the transfer of ions between and within minerals.
C. It stops elements from moving around within Earth's crust.
D. It can have elevated concentrations of dissolved substances.
Answer:
it can have elevated concentrations of dissolved substances
Explanation:
Water is widely regarded as a universals solvent. During a metamorphic process, the presence of fluids most especially water cannot be over emphasized.
Water in metamorphic processes helps to concentrate dissolve materials and moves them from one point to another within the crust. By so doing, water helps to facilitate the rate at which the reaction and transformation occurs. Water available for metamorphic processes usually have elevated temperature, this would further aid to catalyze the transformation work on the rock.
Water plays nearly the same role as pressure and temperature in a metamorphic reaction. It serves as the mobile unit to move materials from one point to the to another. The water concentrates the dissolve materials that comes in contact with it and utilizes it to further produce new metamorphic minerals. Generally, fluids allow for better mobility.
The correct option is D. It can have elevated concentrations of dissolved substances.
Water in metamorphic processes facilitates the transfer of ions between and within minerals, speeding up metamorphic reactions.
It also allows for the transportation of ions from one place to another, crucial in hydrothermal processes and mineral deposit formation.Hot water can have elevated concentrations of dissolved substances, aiding in moving elements within Earth's crust. The presence of water is essential for hydrothermal metamorphism, where chemically reactive fluids play a significant role in altering mineral compositions.
1. By examining the fin of a primitive fish, scientists
have found similarities in bone structure to that of
modern day reptiles, birds, and mammals. What
type of evidence does this describe?
The question discusses the concept of homologous structures, which are similarities in anatomy across different species pointing to a common ancestor. This evidence supports the theory of evolution through common descent, indicating that species evolve divergently from a shared origin.
Explanation:By examining the fin of a primitive fish and noticing similarities in bone structure to modern day reptiles, birds, and mammals, scientists are observing homologous structures. Homologous structures are examples of an anatomical similarity that results from organisms sharing a common ancestor. This type of evidence points towards the evolutionary theory that suggests modern species share a common ancestor. Over time, this ancestral lineage diverged through evolutionary changes, leading to the variety of species we see today. These structures have evolved in different ways to suit the needs of different species but retain an underlying structural similarity that hints at their shared origins.
Homologous structures are not limited to the skeletal system; they can also include other anatomical features that demonstrate a common ancestry. The presence of these structures across different species provides a compelling argument for the concept of evolution through common descent, showcasing how evolutionary pressures and environmental changes have sculpted various forms from an ancestral blueprint.

Cutting down forests changes the populations of more than trees. Imagine the organisms that lived in this forest. After the trees have been cut, fewer animals can survive here. What are MOST LIKELY the limiting factors in this case?
Answer:
Food and shelter are the most likely limiting factors in this case.
Explanation:
In a forest, the huge trees act as a source of shelter for the animals that live in that habitat. It protects the animals from the heat of the Sun and extreme cold conditions.
The tress in the forest are the primary source of food for almost all the organisms that live in the forest. Cutting down trees will lead to food scarcity for the animals which inhabit that forest. As a result, the animals will either have to migrate or they will become die due to lack of food.
Hence, food and shelter are the limiting factors in this case.

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers. Their structure is closely related to their function.
Basic makeup: C, H, O -with many polar OH groups
Further Explanation:
Many long chain polysaccharides are made up of glucose joined by regular α, 1-4 glycosidic bonds used as energy storage (produced through phtosynthesis) and used for ATP synthesis via respiration, ethyl alcohol fermentation and lactic acid fermentation. Branched chains of α, 1-4 glycosidic bonds linked by α(1→6) glycosidic bonds make up glycogen, a storage molecule in animals. Plants are mostly comprised of structural units cellulose and lignin. However, cellulose is their main structural polysaccharide, found within cell walls.
It is made up of special β, 1-4 glycosidic bonds, which give structural polysaccharides their rigid, strong structure; cellulose is not water-soluble and is highly stable. However, if these alternating bonds aren't present, the plants would lose their main structural support, which allows larger plants, and trees to grow upwards towards sunlight despite their mass. When arranged in α 1-4 glycosidic bonds these molecules are water-soluble; water would be able to flow readily out of the plant tissue. Thus the plant cells and tissue, would not retain their shapes and may be limited in their potential height without structural support.

An endurance runner begins experiencing muscle soreness towards the end of a long race.
Explain, in detail, what is happening in her muscle cells. Your answer should include the
molecule(s) that are missing, how this is altering cell respiration, and what the cause of
her soreness is.
Answer and Explanation:
The cells of the runner respire through anaerobic respiration due to inadequate oxygen leading to formation of lactic acid. Under these conditions lactic acid accumulates in the muscles which might cause fatigue and result in muscle soreness and cramps. Lack of enough oxygen makes the cells to respire anaerobically altering cell respiration.
Final answer:
During intense exercises like a long race, endurance runners' muscles switch from aerobic to anaerobic respiration, producing ATP via lactic acid fermentation. The accumulation of lactic acid can cause immediate muscle fatigue and soreness.
Explanation:
During a long race, an endurance runner's muscle cells start to experience an intense demand for ATP (Adenosine Triphosphate), the molecule required for muscle contraction. Initially, ATP is produced via aerobic respiration, a process that efficiently generates ATP but requires oxygen.
As the race progresses, the oxygen supply to the muscles may not keep pace with demand, and the muscles switch to anaerobic respiration, specifically lactic acid fermentation, to meet their energy needs.
This process does not require oxygen and can produce ATP quickly, albeit less efficiently than aerobic respiration. One of the byproducts of lactic acid fermentation is lactic acid.
The accumulation of lactic acid in the muscle cells can lead to a decrease in pH (increasing acidity), which can impair muscle function and contribute to the sensation of muscle fatigue and soreness during and immediately after intense exercise.

calculating waist-to-hip ratio
Answer:
calculating waist-to-hip ratio
Explanation:
The waist-to-hip ratio (WHR) is the calculation from waist and hip measurements to ascertain a person's risk of developing cardiovascular disease. This is because, the higher the concentration of abdominal fat, the greater the risk of having problems such as high cholesterol, diabetes, high blood pressure or atherosclerosis.
The presence of these diseases along with excess fat in the abdominal region of the body also increases the risk of more serious health problems such as heart attack, stroke and fat in the liver, which can lead to sequelae or lead to death. To identify early on, know what are the symptoms of infarction.
In a monohybrid cross, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing an intermediate (Tt) plant with a tall (TT) plant? (Hint: You may want to complete a Punnett square.)
Answer:
T t
T TT Tt
T TT Tt
The punnet square shows that there will be a 50% chance that the offsrpings will have tall height and there is a 50% chance that the offsprings will have intermediate height.
Incomplete dominance can be described as a phenomenon in which the dominant trait is not completely dominant over a recessive trait. As a result, the organisms shows both the traits of the dominant and the recessive allele.
