What is the pH range of highly acidic substances?

Biology
1 answer:
vazorg [7]3 years ago
6 0
The pH scale ranges from 0 to 14, 14 most basic and 0 most acidic. Things under 7 (neutral) is acidic. Highly acidic things are probably lower on the scale, battery acid being 2, 1, or 0 (I'm not sure which of those) I hope this answered, please tell me if not ;)

Which of the following statements about metabolism are true? Catabolism is the process in which complex substances are broken do
Daniel [21]
<h3><u>Answer;</u></h3>
  • Catabolism is the process in which complex substances are broken down, yielding a net output of energy
  • Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
<h3><u>Explanation</u>;</h3>
  • Metabolism is the chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.
  • Catabolism is the metabolic breakdown of complex molecules into simpler ones, resulting in a release of energy. These reactions are exothermic.
  • Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. Anabolic reactions are endothermic.

Which came first: sexual or asexual reproduction?
cupoosta [38]

If i remember correctly asexual reproduction came first because without asexual reproduction the cells would not have been able to produce other cells so what few cells there were reproduced asexually and then it evolved onto sexual reproduction later in development

What is the common name of plant #3 and what biome would it most likely grow in? Name one adaptation that helps it survive in it
Dmitry [639]

Answer:

A biome is a large area characterized by its vegetation, soil, climate, and wildlife. There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

Aquatic biomes include both freshwater and marine biomes. Freshwater biomes are bodies of water surrounded by land—such as ponds, rivers, and lakes—that have a salt content of less than one percent. Marine biomes cover close to three-quarters of Earth’s surface. Marine biomes include the ocean, coral reefs, and estuaries.

Grasslands are open regions that are dominated by grass and have a warm, dry climate. There are two types of grasslands: tropical grasslands (sometimes called savannas) and temperate grasslands. Savannas are found closer to the equator and can have a few scattered trees. They cover almost half of the continent of Africa, as well as areas of Australia, India, and South America. Temperate grasslands are found further away from the equator, in South Africa, Hungary, Argentina, Uruguay, North America, and Russia. They do not have any trees or shrubs, and receive less precipitation than savannas. Prairies and steppes are two types of temperate grasslands; prairies are characterized as having taller grasses, while steppes have shorter grasses.

Forests are dominated by trees, and cover about one-third of the Earth. Forests contain much of the world’s terrestrial biodiversity, including insects, birds, and mammals. The three major forest biomes are temperate forests, tropical forests, and boreal forests (also known as the taiga). These forest types occur at different latitudes, and therefore experience different climatic conditions. Tropical forests are warm, humid, and found close to the equator. Temperate forests are found at higher latitudes and experience all four seasons. Boreal forests are found at even higher latitudes, and have the coldest and driest climate, where precipitation occurs primarily in the form of snow.

Deserts are dry areas where rainfall is less than 50 centimeters (20 inches) per year. They cover around 20 percent of Earth’s surface. Deserts can be either cold or hot, although most of them are found in subtropical areas. Because of their extreme conditions, there is not as much biodiversity found in deserts as in other biomes. Any vegetation and wildlife living in a desert must have special adaptations for surviving in a dry environment. Desert wildlife consists primarily of reptiles and small mammals. Deserts can fall into four categories according to their geographic location or climatic conditions: hot and dry, semiarid, coastal, and cold.

A tundra has extremely inhospitable conditions, with the lowest measured temperatures of any of the five major biomes with average yearly temperatures ranging from -34 to 12 degrees Celsius (-29 to 54 degrees Fahrenheit). They also have a low amount of precipitation, just 15–25 centimeters (six to ten inches) per year, as well as poor quality soil nutrients and short summers. There are two types of tundra: arctic and alpine. The tundra does not have much biodiversity and vegetation is simple, including shrubs, grasses, mosses, and lichens. This is partly due to a frozen layer under the soil surface, called permafrost. The arctic tundra is found north of boreal forests and the alpine tundra is found on mountains where the altitude is too high for trees to survive. Any wildlife inhabiting the tundra must be adapted to its extreme conditions to survive.

bearhunter [10]

Answer:

When I first read this question, all I could think about was the capsized fishing charter called, “the Erik”. The inept captain and crew of this boat caused the death of four passengers while three others remain missing. This disaster occurred back in 2011. I knew two of the passengers. One was recovered in 2013. The other is still listed as missing. However, this question concerns the “best story”. So, I’ll give you the accounts of my own experience. Back in 2013, my group of long-range fishing friends had chartered our annual 8-day trip out of Point Loma, San Diego. We had always chartered the same boat; the Shogun. At our traditional dinner the night before boarding, I remember the most notable topic being discussed was the remnants of Hurricane Ingrid. Ingrid had caused high winds and seas in the area where we wanted to fish.
