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.

Answers

Answer 1

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.

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"

Answers

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 United States is located in North America in the Western Hemisphere. It spans a large amount of the continent, so it covers many areas with unique climates.

The Northeast has a lot of forest cover, and encounters very diverse climates throughout the year, from bitter winters to blistering summers, and have even experienced hurricanes.

The Southeast is generally mild, and experiences warm weather year round. The further south you go, the warmer it gets. You also see more bayous and swamps in the south. The northern ends of the Southeast such as North & South Carolina can experience some snow and colder weather in the winter.

The Midwest is also mild, and generally flat, which makes it ideal for agriculture.

As you go west, you will find more mountainous regions, as well as arid desert landscapes. The Southwest is the pinnacle of these desert landscapes, seeing hot weather in the day, and cold weather in the night, with high temperatures year round.

And finally, the Northwest is a mild climate, with high mountains and abundant rain.

Explain the rock cycle with the help of diagram and how does weathering affect the rock cycle.​

Answers

The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.
Forces like wind and water break down rocks through the processes of weathering and erosion. Weathering is the process that breaks down rocks. ... Weathering and erosion help shape Earth's surface. They are part of a process called the rock cycle.

Answer:

Sedimentary - A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals. ... Metamorphic - These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time.

environmental possibilitiesm believes that human activities are controlled by the evironment?​

Answers

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.

what is moraine? , explain it.​

Answers

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).
