Answer:
Soils are composed of mixtures of mineral and organic materials, but are classified according to the size of their mineral particles. The three main texture groups are sandy, silty, and clay.
Sandy soil contains particles that can be seen with the naked eye and feels gritty when rubbed between the thumb and forefinger. Sandy soils will generally not stick together when wet.
Silty soil contains particles, which are smaller than sand particles but larger than clay particles. Silt feels powdery when rubbed between the thumb and forefinger. Silty soil sticks together when wet, but will not hold its shape after it is dry.
Clay soil contains the smallest particle size. Clay particles form a sticky soil when wet and will generally hold a shape after drying. Soils are rarely composed of just sand, silt, or clay. They are usually a mixture of the three with a larger percentage of one size of particles.
Answer:
Depending upon the average grain-size and the conditions under which soils are formed and deposited in their natural state, they may be categorized into following types on the basis of their structure: In the grain-size classification, soils are designated according to the grain-size or particle-size. The more common classification systems are enlisted below: Geological Classification
Classification by Structure
Classification based on Grain-size
Unified Soil Classification System
Preliminary Classification by soil types
Based on the agencies responsible for their present state, soils may be classified under following types: Residual Soils
Transported Soils:
Alluvial or sedimentary soils
Aeolian soils
Glacial soils
Lacustrine soils
Marine soils.
Then you have inorganic and organic soils.

A species of bird ate many types of seeds, each type coming from a different species
of tree. The birds' beaks varied in size, with some individuals having slightly smaller
beaks and others having slightly larger beaks.
slightly smaller beak
slightly larger beak
A few years went by without much rain, and the only species of tree that survived had
large seeds. Many generations later, almost all the birds had the slightly larger beaks.
How is this best explained?
Answer:
I took this in middle school option 3
Explanation:
Answer:
The bird most likely had to adapt so they had to eat whatever they could. Doing so made their beaks larger, the muscle under neath probably started to grow from all the movement trying to eat the large seeds. LOL i really dont know but it seem reasonable i guess.

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How could this result in the evolution of drug-resistant pathogens?
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
Antibiotics have become diluted and weak because of a limited supply.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Answer:
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
If an air mass is sinking, it must be
A. cold and less dense
B. warm and more dense
C. cold and more dense
D. warm and less dense
Answer:
The awnser to your question is C.
Explanation:
The colder matter is the atoms get closer therefore making the matter more dense. A. is half correct but if the matter is cold it wouldn't be more dense because when something is less dense it goes above whatever is around it. Take for example water and oil. They seperate into different layers due to density. Hope this helps. :)
The airmass is a large homogenous mass of air over a region that could be for many days.
The volume of air is defined by the temperature and water vapor content. Airmass may spread from hundreds to miles and are classified according to latitude and altitude. There are 4 types of air mass artic, tropical equatorial, and polar. The airmass that is light is warm and has a low pressure always lifts upwards. The cold and cool airmass always settles as it's dense and heavy. Hence the option C is correct.Learn more about the air mass is sinking, it must be.

The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work
Answer:
2754.33% increase
Explanation:
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%
Percent change = 2754.33% increase
Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.

One of the concerns about rising CO2 levels ocean water is the negative effect on certain types of marine life, such as oysters and clams. Does your experiment show a negative effect? Explain your answer.
Answer:
see below :)
Explanation:
For many years sea life such as oysters and clams have been acostumed to the temperature of the water. Rising levels of CO2 will cause more heat in water temperatures. This would make the shells of the oysters and clams 'wear away'.
Answer:
yeah the person under me is right
Explanation:
Ocean acidification is a consequence of the excess carbon dioxide in the atmosphere from fossil fuels. When the ocean absorbs the CO2, the water becomes more acidic. Shelled animals like zooplankton, corals, clams, mussels and oysters cannot grow their shells in the acidic water.

Question 1 After evaluating your MyPlate recommendations, make a prediction. Do you think your diet will meet these daily recommendations? Are there any recommendations you don't think your diet will meet?
Answer and Explanation:
I don't think MyPlate's recommendations will meet my daily recommendations because those recommendations are focusing too much on the amount of carbohydrates and are not meeting the need for other types of elements, such as healthy fats, for example. In that case, an extremely high carbohydrate diet will get me into trouble and make my body need it. Ideally, I should look for recommendations from a nutritionist who can, in fact, help me establish a healthy and complete diet.
