Answer:

1. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.

2. Larger pores mean less friction between flowing water and the sides of the pores. Smaller pores mean more friction between flowing water and pore walls and more twists and turns for the water to navigate. A permeable material has a greater number of larger, well-connected pore spaces. An impermeable material has fewer, smaller pores that are poorly connected.

3. A cave is any cavity in the ground that is large enough that some portion of it will not receive direct sunlight.

A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.

4. The size of the pores underground rock material has and if the pores are connected

5. Karst regions are formed when there is a chemical reaction between the groundwater and the bedrock. As rain, streams, and rivers flow over the earth's surface, the water mixes with the carbon dioxide that naturally exists in air, and the soil becomes acidic and corrodes the calcium carbonate rock. The carbonate solution seeps into fissures, fractures, crevices, and other depressions in the rock. Sinkholes develop and the fissures and crevices widen and lengthen. As the openings get larger, the amount of water that can enter increases.

Answer:

1.In the zone of aeration, some of the pore space is occupied by air, and some of the pore space is occupied by water. In the zone of saturation, all of the pore space is occupied by water.

2.It's easier for water to flow through large pores because there's less friction between the flowing water and the pore walls. Smaller pores create more friction between flowing water and pore walls. In addition, smaller pores create more twists and turns for the water to flow around.

3.A cave is a natural, underground chamber that connects to Earth’s surface. A cavern is a type of cave where speleothems form. All caverns are caves, but not all caves are caverns.

4.The two factors that determine how easily water can move through rock or sediment are the slope of the water table and the permeability of the rock or sediment.

5.Karst topography, which includes sinkholes and caves, occurs in areas with a lot of limestone, dolomite, and gypsum. When water and carbon dioxide react, they form carbonic acid. This weak acid solution is able to dissolve these materials, leading to the formation of many karst features.

Which one of the following best describes the functions of carbohydrates with living things?
kozerog [31]

It’s between b and d. I would go with b based on the information below.

The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses. Simple carbohydrates are quick energy sources, but they do not usually supply any other nutrients or fiber. One of the most important functions of carbohydrates is to form a structure called the glycocalyx. This is a coat around the cell.

The new Hazard Communication Standards provide teachers and students the right to __________ chemical hazards.
Aleonysh [2.5K]

The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.

Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, <u>employees are exposed to them and are vulnerable to harm from these chemicals</u>.  

There are many types of hazardous chemicals to be wary of, such as:

  • Carcinogens
  • Neurotoxins
  • Acids
  • Systemic toxins
  • Asmogens
  • Silica dust
  • Lead

In the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.

The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. <u>This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies</u>, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.

Therefore, by having these safety standards in place in schools and universities, teachers and students have the possibility and the right to handle chemical hazards safely to be able to conduct the class normally and learn what is necessary.

In a population fulfilling all the assumptions of the Hardy-Weinburg equilibrium, allelic frequencies:
Rzqust [24]

Answer:

A. will not change from generation to generation.  

Explanation:

For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:

-The population is large enough.

-Individuals of the population exhibit random mating .

-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.

Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".
