PLEASE HELP ME 100 POINTS ON THE LINE!!!! AG QUESTIONS! LMK IF YOU CAN HELP ME WITH ANY MORE TYSM!
Which of the following terms refers to the size of soil particles?

Soil texture

Soil structure

Soil pH

Soil composition


Which of the following is NOT a type of soil aggregate?

Platy

Crumby

Blocky

Granular


Which of the following best describes leaching?

Water brings nutrients from below plant roots so they are available to plants.

Nutrients come from groundwater and streams and appear in the soil for plant use.

Nutrients accumulate in water then are supplied to plants through the soil.

Water carries nutrients below plant roots where they are unavailable to plants.


Which of the following is NOT true about soil pH?

Acidic soil has a pH less than seven

When soil pH is high, micronutrients tend to be less available

It is a measure of the alkalinity or acidity of soil

Soil pH does not affect the availability of nutrients


Which of the following best describes a loam soil?

Soil particles which are smooth and small in size

Soil which contains high organic matter content

Soil which contains relatively equivalent portions of sand, silt and clay

Soil particles which vary in size and resemble cookie crumbs

Answer: The texture of soil determines soil water-holding capacity, permeability, and soil workability. Sand, silt, clay, and organic matter particles in a soil combine with one another to form larger particles. Soil structure is the arrangement of the soil particles into aggregates of various sizes and shapes. THEREFORE THE ANSWER TO THE FIRST ONE IS A) SOIL TEXTURE.

FOR THE SECOND QUESTION THE ANSWER IS B) CRUMBY.

FOR THE THIRD QUESTION THE ANSWER IS D) Water carries nutrients below plant roots where they are unavailable to plants.

FOR THE FOURTH QUESTION THE ANSWER IS D) Soil pH does not affect the availability of nutrients

FOR THE FIFTH QUESTION THE ANSWER IS C) Soil which contains relatively equivalent portions of sand, silt and clay

Explanation: Good luck you got this!!! :))

A researcher wants to determine whether there is a relationship between age and frequency of travel. In a random sample of 18- to 25-year-olds, 70 of 195 traveled more than twice each year. In a random sample of 55- to 62-year-olds, 205 of 230 traveled more than twice each year. What is the margin of error for a 98% confidence interval for the difference between the proportions of travelers in these age groups who travel more than twice each year?

A researcher wants to test the claim that the proportion of men and women who exercise regularly is not the same. He finds that 42 of 65 randomly selected men and 34 of 52 randomly selected women report exercising regularly. A 90% confidence interval for the difference in population proportions is (−0.154, 0.138). Which of the statements gives the correct outcome of the researcher's test of the claim?


Because the confidence interval includes zero, the researcher can conclude the proportion of men and women who exercise regularly is the same.
Because the confidence interval includes zero, the researcher can conclude the proportion of men and women who exercise regularly may be the same.
Because the confidence interval includes zero, the researcher can conclude the proportion of men and women who exercise regularly is different.
Because the confidence interval includes more positive than negative values, the researcher can conclude that a greater proportion of men than women exercise regularly.
The researcher cannot draw a conclusion about a claim without performing a significance test.
