Answer:
World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored?
Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science.
Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainability—in areas such as human settlements, agriculture, industry, and energy—and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.

Explanation :
In simple words, Planting multiple crops in appropriate combinations throughout the identical field is known as intercropping. Crop rotation is the process of changing the crops cultivated on a farm from one harvest to the next. On steep hillsides, terracing provides flat floors for plants to collect rainfall and decrease desertification.
what is moraine? , explain it.
Answer:
Explanation:
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet).
what are the three types of materials that affect light differently
Answer:
Explanation:
The purpose of this lesson is for the students to learn that light interacts differently with different types of materials. Students will be able to categorize materials into 3 categories based on how the light interacts with those materials: transparent (light shines through), translucent (some light shines through, and opaque (no light shines through).
Answer:
Glass, plastic, mirrors="If a material is a light colour or has a smooth surface, more light will be reflected. Shiny opaque materials, such as mirrors, reflect most of the light that strikes them. If a material is a dark colour or has a rough surface, more light will be absorbed. Opaque objects that absorb light also become warm."

A certain sample of limestone formed when shells from organisms were buried under layers of sediment and experienced pressure. A student classifies the sample as clastic sedimentary rock. What is one problem with this classification
Answer:
The problem with this classification is clastic sedimentary rocks are not formed with organic elements, that is, they do not form with the remains of organisms, such as shells, for example
Explanation:
The student made an incorrect classification. This is because he classified a rock formed from shells as clastic sedimentary rock.
Shells are organic materials, as they are the remains of living organisms. Organic material is not capable of forming clastic sedimentary rocks, as these rocks are formed only by sediments. Remains of organisms, manage to form a type of rock called organic rock.

Which of the following statements is true? Group of answer choices Temperature inversions make pollution problems worse. Normally, cool air near earth's surface expands and rises, carrying pollutants higher into the troposphere. Temperature inversions help prevent air pollution. Temperature inversion occurs when a layer of cold air prevents warm air from rising.
Answer:
Normally, cool air near earth's surface expands and rises, carrying pollutants higher into the troposphere.
Explanation:
Thermal inversion is an atmospheric phenomenon. It tends to occur in large urban centers where industrial production is intense and the amount of polluting gases is greater. When the thermal inversion happens, the cold air is trapped and is prevented from circulating. This cold air is trapped close to the Earth's surface, very close to the toposphere. The problem is that cold air is loaded with polluting gases and this promotes strong atmospheric pollution, which aggravates many environmental and health problems. It is because of the thermal inversion that we can see a gray layer on the horizon of some urban centers.

Explanation:
Hope This Helps If It Wrong Please Tell Me
A part of a reflecting telescope would you measure to find the aperture is the mirror.
What is a telescope?Scientists can observe celestial stars using a telescope. When collecting light, refracting telescopes use lenses, while reflecting telescopes utilize reflectors in order to observe an object.
The aperture in refractors refers to the thickness of the lens at the top of the tube. The diameter of the bottom tube's mirror, where light is collected, is used to measure reflectors.
White light is made up of a spectrum of colors, according to Isaac Newton, who developed his reflecting telescope as evidence for this theory in order to see far way objects.
The mirror size of a reflecting telescope is used to calculate the aperture. When selecting a telescope, the aperture—or the width of its primary mirror or lens—should be your primary consideration.

Rivers downcutting into a land surface, in the absence of other forces, usually tend to erode a ________-shaped form when viewed in cross-section across its valley. flat bottomed U delta V groove
Answer:
Rivers downcutting into a land surface, in the absence of other forces, usually tend to erode a V-shaped form when viewed in cross-section across its valley.
Explanation:
Rivers on steep surfaces tend to have a very high flow speed and the higher the slope of the terrain and the speed of the river, the greater the erosion power of these rivers. Under these conditions, a river can deepen its bed, creating a V-shaped valley, especially at the headwaters of the banks, where the erosion process is usually greater.
Utilizando los conceptos soberanía alimentaria, agriculturización, monocultivo,
expansión de la frontera agropecuaria, seguridad alimentaria y éxodo rural;
explica la siguiente frase: "LA FABRICA QUE PRODUCE POBRES ESTA EN EL
MODELO RURAL"
Answer:
La frase "La fábrica que produce pobres está en el modelo rural" es una clara referencia a que el modelo rural, en contraposición con el modelo industrial imperante en la enorme mayoría de los países económicamente desarrollados, es un sistema económico de poca proyección, con baja capacidad de proyectar sus ganancias y beneficios al común de la sociedad, sino por el contrario a un selecto grupo de individuos que desarrolla la actividad a gran escala.
Así, el resto de los pequeños productores no logra escalar en el sistema, cayendo en la pobreza y sin posibilidades de acceder a una verdadera seguridad alimentaria, con lo cual se produce el éxodo rural: los campesinos pobres emigran a las ciudades en busca de oportunidades.
Si un país no tiene una economía compleja y con distintos sectores armónicamente complementarios, es muy difícil que este alcance una verdadera soberanía alimentaria (la capacidad de que cada individuo se alimente y subsista por sus propios medios): la agriculturización de la sociedad, en pleno siglo XXI, es improcedente, dado que el valor agregado de los productos industriales es la fuente de las mayores riquezas en la actualidad.
Por lo tanto, debe abandonarse el sistema rural y agricologanadero, para pasarse a un sistema mixto: industrial y con un sector agropecuario caracterizado por los monocultivos, es decir, la producción específica de bienes agrícolas para la exportación.
The tiny fruit fly is a superstar of genetics research. Thousands of experiments have explored how flies inherit traits. Wing shape, body color, eye color, and head shape are a few traits under investigation. Fruit flies make good study subjects because they are inexpensive, take little space, and breed quickly. In addition, humans and fruit flies share 75% of their disease genes. By studying fruit-fly genetics, we can learn about human illness.
Short-winged fruit flies studied in the lab cannot fly because they have an allele that causes them to grow tiny wings (w). Normal fruit flies, known as “wild-types”, have fully functional wings (W). The wild-type wing is the dominant allele.
If you cross one short-winged fly (ww) with a wild-type fly (WW), what is the probability of getting a short-winged offspring in the F1 generation?
Explain your reasoning.
Answer:
a. 0
b. There are no short winged genes expressed in this generation
Explanation:
a. What is the probability of getting a short-winged offspring in the F1 generation?
Since we have the ww gene for the short winged fly and the WW gene for the wild type fly.
In the F1 generation, we have
Ww, Ww, Ww and Ww
Since the W wild-type allele is the dominant gene, in the F1 generation, all the fruit flies have wild-type wing.
Probability of short-winged fly, P(short-winged) = number of short-winged genes/total number of genes =
number of short-winged genes = 0
total number of genes = 4
P(short-winged) = 0/4 = 0
b. Explain your reasoning.
Since the wild winged type allele is the dominant gene, there are no short winged genes expressed in this generation. Thus, the probability of obtaining a short-winged fly in the F1 generation is therefore zero.
