The chaparral biome is best characterized by _______. a. large, contiguous regions of shrubland b. small regions interspersed with other biomes c. large noncontiguous regions interspersed with other biomes d. the animals dwelling in it please select the best answer from the choices provided a b c d
''a. large, contiguous regions of shrubland'' are the characteristics of the chaparral biome.
What are the characteristics of the chaparral biome?
Chaparral is a type of woodland that is characterized by a combination of dry soil, warm weather, and short and hardy shrubs. The chaparral biome is dominated by short types of woody plants instead of grasses that are present in the grassland biome or tall trees which are present in forest biomes. The chaparral is unique and present on the Pacific coast of North America. Chaparral is a temperate biome that is characterized by hot-dry summers, and mild and rainy winters. Nearly all of the rainfall occurs in the winter and spring rainy seasons at the Chaparral.
So we can conclude that the chaparral biome is best characterized by large, contiguous regions of shrubland.

Why do scientists think gases such as CO2 trap heat in the atmosphere?
Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can trap heat. Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth.
Carbon dioxide is Earth's most important greenhouse gas that works for absorbing and radiating heat. Greenhouse gases absorb heat radiating from the Earth's surface and even circulate it in all directions including back toward Earth's surface.
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere's carbon dioxide content by 50% in less than 200 years.

Some individuals are unable to digest the lactose found in the milk of cows. The digestive systems of these individuals most likely lack which of the following?
A.
a lipid that coats lactose molecules
B.
an ability to produce lactose internally
C.
an enzyme that catalyzes lactose breakdown
Some people cannot digest the lactose found in milk. This person's digestive system is deficient in any of the following. The ability of the body to produce lactose.
Sugar is found in milk. It is a disaccharide containing glucose and galactose units. When a person with lactose intolerance consumes dairy products, lactose from these components can enter the intestines and cause gas, cramps, bloating, and diarrhea. Some people can eat small amounts of dairy without any problems. Others have stomach problems and want to avoid all dairy products. Signs of lactose intolerance include nausea, cramps, gas, bloating, or diarrhea within 30 minutes to 2 hours after drinking milk or dairy products. Symptoms occur because the scaffold does not produce enough lactase to digest the ingested lactose.
Lactose is one of the main components of human and animal milk. As a disaccharide containing glucose and galactose, lactose has a fortifying effect on milk. Eggs are not mammals and come from birds, including chickens, ducks, or quails that do not currently produce milk. Eggs are rich in protein and contain many essential vitamins and minerals. They no longer contain lactose, so they can be eaten by people with lactose intolerance and who are allergic to eggs.

More energy can be from fat molecule than from glucose molecule because the fat molecule contains more
Answer: Hope this helps.
Explanation: Triglycerides store about twice as much energy as carbohydrates. Triglycerides are made of glycerol and three fatty acids. Because there are so many carbons in three fatty acids, and each 2-carbon unit can enter the citric acid cycle, one fatty acid molecule can generate much more ATP than one molecule of glucose.
Answer:

The organelle is common to many types of cells and is the primary site for storage of materials such as water, proteins, lipids, and cellular waste. The size of the organelle can vary between plants and animals depending on its general function. True or false?.
Answer:
I believe its True
The organelle is common to many types of cells and is the primary site for storage of materials such as water, proteins, lipids, and cellular waste. The size of the organelle can vary, and it is a vacuole. This is the true explanation.
What are the different functions of the cell organelles?The cell organelles are different in different organisms, such as plants, animals, yeast, etc., because the cell organelles and their functions vary too. The plant cell has a large vacuole, which contains water, proteins, lipids, cellular waste, etc., it has mitochondria, a nucleus, etc., and the function of the vacuole is different from that of the animal cell vacuole. The vacuole of the plant cell is larger than that of the animal cell because the plant cell vacuole maintains the water pressure, but the animal cell does not do this.

True, the archaea and eukarya are more closely related to each other than they are to the bacteria
The archaea, eukarya and bacteria are described by the Woese's tree of life.
What is Woese's tree of life?
This is a unique research program developed by Carl Woese, it is based on rRNA, for discerning bacterial relationships and constructing a universal tree of life. Woese's interest in the evolution of the genetic code led to him to investigate the deep roots of evolution, develop the concept of the progenote, and conceive of the Archaea.
The tree indicates that the common ancestor for eukarya and archaea is more recent than the common ancestor for all three domains.
Eukarya are therefore more closely related to the archaea than is to the bacteria.

Using food pyramids, explain why a vegetarian diet is more "ecologically responsible."
The responsibility to preserve and protect the environment is known as ecological responsibility. The majority of the time, ecological responsibility is related to businesses making sure that their operations always abide by environmental laws and regulations.
Explain about vegetarian diet is more Ecologically responsible?People can drastically minimize their consumption of land, water, and oil resources as well as the amount of pollution they might otherwise generate by selecting a vegetarian diet rather than one high in animal products.But when the study's 153 vegans, vegetarians, and omnivores were all included in, it became clear that eating meat was, on average, worse for the environment. When we think about food crops, there are other broad issues to keep in mind that could have a greater negative influence on the ecosystem.According to a thorough peer assessment of studies on vegetarianism, a non-meat diet will probably result in a person emitting less carbon dioxide than they would with a meat-based diet—roughly 1,200 pounds less carbon dioxide. That translates to a mere 4.3% reduction in emissions for the average person living in industrialized nations.

[Anatomy, Articulations Homework] The special movement of drawing a back a "jutted out" mandible is known as?
The special movement of drawing back a "jutted out" mandible is known as erotrusion.
A jutted out mandible is called protrusion. The opposite of protrusion is retrusion. The movement of a structure in a posterior, or backward, direction, is what is meant by this term. Retrusion in anatomy might manifest as putting your tongue back in your mouth, pulling your lips back, or pulling your jaw back.
Prognathism is sometimes known as a Habsburg jaw or a prolonged chin. Prognathism typically refers to an excessive protrusion of the lower jaw.
Depending on which jaw is impacted, prognathism can result in either an overbite or an underbite. Prognathism could be a symptom of a medical disease that has to be treated.

Article of plastic in the ocean.
Why or how does the article occur ?
Also provide a brief personal reflection on the article that you have given me
Earth's last sink for plastic waste, the oceans, receive the majority of it from the land. Major rivers operate as conveyor belts, gathering up debris as they flow downstream and carrying it to the ocean. Many pieces of plastic waste that are floating at sea stay in coastal waters.
Why is plastic in the ocean happening?Plastic garbage is transported through drains, streams, and rivers by wind and rain. Ocean access is via drains! Another significant factor is careless and incorrect garbage disposal; unlawful rubbish dumping significantly contributes to the plastic pollution of our oceans.Being such a persistent contaminant, plastic waste is particularly harmful. Decomposition of plastic products might take hundreds of years. Both people and animals are at risk from this garbage. In the debris, fish become entangled and hurt, and some animals mistakenly eat things like plastic bags thinking they're food.To learn more about : Plastic pollution
