Final answer:
The term 'beriberi' refers to a deficiency condition caused by a lack of thiamine (vitamin B-1), leading to symptoms affecting the nervous and cardiovascular systems, potentially fatal if untreated. It commonly arose from diets reliant on polished white rice, which lacks thiamine. This condition highlights the importance of vitamins in human nutrition.
Explanation:
The diagnostic term beriberi refers to a medical condition that is caused by the lack of thiamine (part of B complex, specifically B-1) in the diet. Beriberi showcases various symptoms including loss of appetite (anorexia), polyneuritis (defects of nervous system), edema, cardio-vascular changes, weakness, muscular atrophy, headache, insomnia, and gastro-intestinal disorders. It can assume four forms: Dry Beriberi, where nervous symptoms prevail; Wet Beriberi, associated with edema; Acute Pernicious Beriberi, affecting the heart; and Mixed Beriberi, which combines symptoms of the other types. Infantile Beriberi is another form seen in breastfed children with thiamine-deficient mothers' milk.
Thiamine is essential for every cell, notably affecting respiration and metabolic processes. Deficiency may result in conditions like Korsakoff's syndrome, optic neuropathy, and can have a potentially fatal outcome if untreated. Causes of thiamine deficiency include poor nutrition, consumption of foods with thiaminase, chronic alcoholism, and various chronic diseases.

What color of light would most likely be present at 200 meters below sea level, and why? Justify your answer.
Answer: Blue light
Explanation:
Blue colored light will reach the depth of the sea as it is not absorbed and reaches the depth of the sea. Blue light penetrates the deepest this is the reason why clear ocean water and some other tropical water appears blue most of the time.
The particles in water affects the transmission of light inside the water. As the coastal water has more particles so they appear more brownish or greenish.
Else, the water appears blue in color.

Connective tissue is different from the other major tissue types in that ______.
Connective tissue differs from other major types of tissue in its structure, functionality, and diversity. Its main characteristic is the presence of cells dispersed within an extracellular matrix composed of proteins and various substances. This tissue can also vary greatly in form, including loose and dense connective tissue, supportive (bone and cartilage), and fluid connective tissue.
Explanation:Connective tissue is different from other major tissue types primarily due to its structure, functionality, and diversity. Unlike other tissues where cells are tightly packed, connective tissue cells are dispersed within an extracellular matrix, which is usually abundant and composed of proteins and organic/inorganic substances. This matrix is produced by the connective tissue cells, playing a crucial role in the functioning of this tissue.
Connective tissues vary greatly in form and function, but commonly contain three components: cells, a large amount of ground substance (the matrix), and protein fibers. They can be found in a wide range of types including loose connective tissue, dense connective tissue, supportive connective tissue (like bone and cartilage), and fluid connective tissue (like blood and lymph). These tissues play different roles ranging from connecting and supporting other tissues and organs to protecting the body from microorganisms, transporting fluids, and storing energy.

Infer why there is more species diversity in southern florida than there is in northern alaska
The correct inference is that the climate in southern Florida supports a higher level of species diversity compared to the climate in northern Alaska.
To understand why there is more species diversity in southern Florida than in northern Alaska, one must consider several ecological and climatic factors.
1. Temperature: Southern Florida has a tropical climate with warm temperatures year-round. This allows for a longer growing season and more consistent food availability, which can support a wider variety of species. In contrast, northern Alaska has an arctic climate with harsh, cold winters and a much shorter growing season, which limits the types of species that can survive there.
2. Precipitation: Florida receives abundant rainfall throughout the year, which supports lush vegetation and a variety of habitats, such as wetlands, forests, and coral reefs. These diverse habitats can support a greater number of species. Northern Alaska, on the other hand, is much drier and has less vegetation, which reduces habitat variety and the number of species that can thrive.
3. Latitude: As a general rule, species diversity tends to decrease as latitude increases. This is known as the latitudinal diversity gradient. Southern Florida is located at a lower latitude, closer to the equator, where higher solar energy input supports more complex ecosystems and a greater diversity of life. Northern Alaska is at a much higher latitude, where the lower solar energy input results in simpler ecosystems and less species diversity.
4. Evolutionary History: Southern Florida has been less affected by glaciations and has had a more stable climate over geological time scales, allowing for a longer period of species diversification. Northern Alaska, due to its history of glaciations, has had repeated disruptions to its ecosystems, which can limit the build up of species diversity.
5. Habitat Heterogeneity: Florida's landscape is characterized by a variety of ecosystems, including the Everglades, hardwood hammocks, pinelands, and mangroves. This heterogeneity provides numerous ecological niches that different species can adapt to and exploit. In contrast, the habitat in northern Alaska is more homogeneous, with vast expanses of tundra and boreal forest, which support fewer species.
6. Isolation: Northern Alaska is more isolated due to its location and the presence of geographical barriers such as mountains and the Arctic Ocean. This isolation can limit the number of species that can migrate to and from the region. Florida, being part of a larger continental landmass and having a peninsular shape, is more accessible to species migrating from nearby regions, thus increasing its species diversity.
In summary, the combination of a tropical climate, abundant rainfall, lower latitude, stable evolutionary history, greater habitat heterogeneity, and less isolation contributes to the higher species diversity observed in southern Florida compared to northern Alaska.

Glucose and amino acids move in or out of a cell by _____.
passive diffusion
facilitated diffusion
active transport
endocytosis and exocytosis
The correct answer is:
facilitated diffusion.
Glucose and amino acids move in or out if a cell by facilitated diffusion. Facilitated diffusion is the passive transport of molecules, ions, and particles towards a specific membranous protein.
Explanation:
Facilitated diffusion is the means of spontaneous passive transport of molecules or ions crossed a biological membrane through distinct transmembrane integral proteins. In the cell, examples of molecules that necessity uses expedited diffusion to move in and out of the cell membrane are glucose, sodium ions, and potassium ions. They pass using carrier proteins through the cell membrane without power near the concentration gradient.
A solution tested in the laboratory shows pH 14. Which of the following statements best describes this solution?
It is a highly acidic solution with a high hydrogen ion concentration.
It is a highly basic solution with a low hydrogen ion concentration.
It is a highly basic solution with a high hydrogen ion concentration.
Answer:
It is a highly basic solution with a low hydrogen ion concentration.
Explanation:
A basic solution is one that has a low concentration of H + atoms, but has a high concentration of OH- atoms. In addition, these solutions have a pH greater than 7, the further away from 7 the pH value, the stronger the base.
With that, we can say that a solution with pH 14, is a highly basic solution, with low concentration of hydrogen atoms.

Some species of moose are adapted to eat grasses and flowers in the summer and pine needles in the winter. Where are these organisms adapted to live? deserts taigas tropical rain forests grasslands
Answer: Taiga
Taiga is the largest terrestrial biome. It is found in Europe, North America and Asia. It is known for the largest diversity of coniferous trees. This biome is characterized by short, wet summers and long, cold winters. It receives plenty of precipitation during summers and plenty of snow during winters. The moose species in summer are adapted to eat grasses and pine needles in the winter because in winters the soil of the taiga biome get freezed, which cannot support the growth of grasses in taiga in winters. The trees shed their leaves as there is no appropriate sunlight to support photosynthesis. The coniferous trees have needles which are covered with wax, to prevent the loss of available water. Hence, trees conserve water and nutrition in the adverse and harsh environment. Therefore, moose species population will be entirely dependent on pine needles as a source of food.

What is the variety of organisms that are able to adapt to various environments on earth?
Species diversity refers to the wide variety of organisms on Earth, ranging from single-celled bacteria to complex multicellular animals and plants. It is the product of evolution, where mutations lead to adaptations that enable species to survive in diverse environments, including extreme conditions. Natural selection plays a key role in the survival and reproductive success of these organisms.
The variety of organisms that are able to adapt to various environments on Earth is known as species diversity. This diversity includes everything from single-celled organisms like bacteria to complex multicellular organisms like animals and plants. The process of evolution has resulted in a wide range of adaptations that allow species to survive in many different types of environments, including extreme conditions. Some of these extreme conditions are high temperatures, extreme cold, high salt concentrations, and high pressure at the bottom of the ocean. Certain extremophile organisms have developed unique adaptations, such as antifreeze proteins to withstand freezing temperatures, or enzymes that function optimally at high temperatures.
Throughout Earth's history, the environment has constantly changed, leading to new species appearing and many becoming extinct. As a result of mutations, or random changes in hereditary material over time, organisms have the possibility to adapt to changing environments, thus increasing their chances of survival. The variety of life on Earth—from bacteria to humans—is rich and complex, and it is continuously shaped by the forces of natural selection, where organisms with traits better suited to their environment tend to have greater reproductive success and survive.

Answer:
Option C, Connective Tissue
Explanation:
The proteins released by organs that repeatedly stretch and retract has favorable electrical property help in building and supporting healthy connective tissues. Tendons and ligaments are generally composed of connective tissues. Endomysium is a form of connective tissue that surrounds each muscle fiber or muscle cells . A group of muscle cells is encircled by a perimysium connective tissue thereby forming a fascicle. All the fascicle are enclosed by epimysium connective tissue to form a compete muscle. The three linings formed by endomysium, perimysium and epimysium in their extended stage form a cord like extension known as tendon.
Thus, the correct answer is option C
