All of the following factors help to reduce the total fertility rate (TFR) except education & employment for women improved medical care that reduces infant mortality. social security to help support the elderly. living in the countryside or on a farm. birth control & family planning.

Question 7 1 / 1 pts

How does industrialization and modernization help to reduce fertility rates?

Select all that apply.

More industrialized and modern nations are more likely to pass laws that limit the number of children a couple may have.

Women are more likely to be going to school or working, so they start having children at a later age.

It increases the costs of raising & educating children who are going to school instead of working.

Technology increases efficiency, which reduces the need for children in the workforce.

They use more resources, which results in greater pollution.

Populations continue to grow exponentially until nations enact strict laws regulating birth rates.

The reduced population has a smaller ecological footprint which results in less pollution.

PartialQuestion 10 0.33 11 pts From the population video you viewed, "How Many People Can Live on Planet Earth," we learned that China, India, and Rwanda have all tried to reduce their population growth rates through different methods.

Match the method of each country that was discussed in the video.

Education program for all children, but especially for girls.

Rwanda

V

Government program that provides free or low-cost contraceptives and family planning.

India

Central America The Andes Mountains of South America

Question 13 1 / 1 pts In tropical areas, many farmers engage in Swidden agriculture, also known as slash and burn, where they burn down areas of the tropical rainforest, dig the ash from the plants into the soil, and then grow crops temporarily. They then move to new areas of forest to repeat this process after nutrients from the ash are depleted.

Why has this form of agriculture developed in tropical zones?

The soils are made up of sand and the nutrients sink into deep layers of the soil horizons.

There are many animals living in the soil that eat all of the soil nutrients, leaving little for plants.

Soils are low in nutrients in tropical areas because the topsoil is washed away by abundant, regular rainfall.

The hot, tropical weather and sunshine bakes the soil and destroys all of the nutrients.

Question 14 1 / 1 pts Soil is made up of all of the following EXCEPT, Disintegrated rock and minerals.

Decaying material like dead leaves and animal waste.

Plastic particles.

Microorganisms like bacteria and fungus.

Earthworms and many types of insects.

Question 17 1 / 1 pts Monoculture, the practice of planting large areas with a single type of crop,. accounts for less than 1% of US croplands requires no chemical fertilizers or pesticides is a development of industrial agriculture is typical of Native American farming techniques

Question 18 1 / 1 pts Which of the following can lead to severe erosion as seen in American Dust Bowl of thel930’s?

Select all that apply. over-tilling and plowing soil and leaving it fallow to be eroded by wind & rain overgrazing of soil by livestock farming on slopes that allows topsoil to be eroded by rain and irrigation growing cover crops like alfalfa between harvest seasons

Question 19 1 / 1 pts The consequences of over-fertilization can include.

Select all that apply. air pollution, including climated change, when nitrogen fertilizer volatilizes in the air compaction and degredation of soils overtime increases in wildlife in surrounding areas pollution of freshwater supplies leading to health problems like Blue Baby Syndrome an increase in tornadoes in farm areas

Question 20 1 / 1 pts Synthetic, chemical fertilizers provide nutrients to the soil but they do not provide organic matter or maintain the proper soil chemistry, which is crucial for the survival of

decomposers like soil bacteria & detritivores like worms. crops like corn and wheat. pathogens and diseases. crop pests like caterpillars.

Question 21 1 / 1 pts One way to reduce water use & avoid over-irrigation of crops is to Only grow crops in parts of the world with abundant rainfall.

Stop farming and go back to hunting & gathering.

Grow only plants that don’t require any water.

Question 22 1 / 1 pts Pesticides are chemicals or poisons that kill or destroy pest organisms like weeds, insects, and fungus that harm valuable crops.

True False

Question 23 1 / 1 pts Why is it likely that pests will become resistant to pesticides over time when they are used in agriculture?

Pests learn to fly away or burrow deep underground to avoid pesticides when they are sprayed only to emerge unharmed later.

Pesticides lose potency over time with exposure to sunlight and water.

A small fraction of large pest populations may have genes that confer some degree of immunity to a given pesticide, so they will survive and pass their resistant genes on to their offspring.

Spray more pesticides in their gardens to kill off insect pests.

Increase the amount of paved materials, like concrete, in their yards.

Grow more flowering plants in their gardens & even balconies that honeybees could use as a food source.

Kill all butterflies & wasps because they compete with bees for nectar plants.

Question 32 1 / 1 pts What is true about genetic engineering or modification (GM)?

Select all that apply.

Corn and wheat are the only GM crops grown in the U.S. Europe leads the world in land area dedicated to GM crops.

Genetically modified (GM) organisms are created through genetic manipulation of DNA, which mixes genes to create new traits in the target species.

They are unanimously favored by farmers and scientists, and the public.

GM mimics genetic mutation while traditional plant breeding is more like natural selection.

Question 33 1 / 1 pts Which of the following statements about gene editing are true?

Select all that apply.

Gene editing is just a theoretical idea that has not been tested in a laboratory setting yet.

Gene editing can potentially produce crops that are drought tolerant, resistant to disease, or more nutritious.

A small section of DNA can be changed using a technology called CRISPR. Gene editing can only be used to make plants tolerate pesticides like Roundup.

Scientists can make precise changes to a plant or animal's own DNA that could happen through traditional breeding but would have taken much longer.
