Which came first, the Chicken or the Egg?
Eggs come from chickens and chickens come from eggs: that’s the basis of this ancient riddle. But eggs – which are just female sex cells – evolved more than a billion years ago, whereas chickens have been around for just 10,000 years. So the riddle is easily solved…or is it?
Taken at face value, there is no doubt that the egg came before the chicken. We tend to think of eggs as the shelled orbs laid by birds from which their chicks hatch – unless we eat them first. But all sexually reproducing species make eggs (the specialised female sex cells). That’s 99.99 per cent of all eukaryotic life – meaning organisms that have cells with a nucleus, so all animals and plants, and everything but the simplest life forms.
We don’t know for sure when sex evolved but it could have been as much as 2 billion years ago, and certainly more than 1 billion. Even the specialised sort of eggs laid by birds, with their tough outer membrane, evolved more than 300 million years ago.
As for chickens, they came into being much later. They are domesticated animals, so evolved as the result of humans purposefully selecting the least aggressive wild birds and letting them breed. This seems to have happened in several places independently, starting around 10,000 years ago.
The wild ancestor of chickens is generally agreed to be a tropical bird still living in the forests of Southeast Asia called the red junglefowl – with other junglefowl species possibly adding to the genetic mix. From these origins, humans have carried chickens around the world over the past two millennia or more.
So, eggs dramatically predate chickens. But to be fair to the spirit of the riddle, we should also consider whether a chicken’s egg predates a chicken. As humans consistently chose the tamest red junglefowls and bred them together, the genetic makeup of the resulting birds will have shifted. At some stage during this domestication process the red junglefowl (Gallus gallus) evolved into a new subspecies, Gallus gallus domesticus, AKA the chicken.
In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some point two junglefowl bred and their offspring was genetically different enough from the species of its parents to be classified as a chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looked at this way, the chicken came first.

C. Compared to factory-made dairy products and condiments, these preservative-free goods have
a decreased shelf life, which increases the prices of the goods sold
d. Domestication of plants and animals began in the Fertile Crescent and the process diffused as
pastoral nomads migrated to other areas
Domestication of plants and animals began in the Indus River valley and the process diffused to
other areas across trade routes
e
Answer: B. Compared to plain milk or fresh fruit, these value-added agricultural goods significantly increase the price of the farm products sold and increase earnings for farmers
Explanation:
These value-added agricultural products greatly raise the price of the farm items sold and improve farmer incomes as compared to plain milk or fresh fruit.
What was economic advantage of the type of farm-produced goods ?The activity of developing natural resources for economic gain and human sustenance is known as agriculture. It blends innovative production techniques and cutting-edge technologies with the creativity, inventiveness, and expertise required for raising animals and cultivating crops.
Commodities, or basic goods utilised in commerce, such as grain, livestock, dairy, fibre, and raw materials for fuel, are also provided by agriculture to the world economy. For instance, according to The Balance Small Business, fibre is the top crop produced in the United States and is a crucial commodity for the apparel industry.
Shipping is necessary for the import and export of goods, such as agricultural products.techniques as road, rail, and maritime freight. The worldwide supply chain may be impacted by delays in the shipping of agricultural items from a Los Angeles port to China and vice versa.

Explain the difference between a Long Profile and a Cross Profile of a River.
Answer:
The average flow velocity of a river increases along its long profile. This makes sense; along the profile, more potential energy is converted to kinetic energy, increasing the velocity. This is only the average velocity however; a cross-section of a river shows that the velocity varies from one side to the other.

Explanation:
The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows.
why do we need visit Kathmandu?
Answer:
I think Kathmandu is indeed worth a visit, in the city centre there are the royal palace, and important religious sites, and the old town. If you need some scenery you have go out a little bit from the city, but you will be in Kathmandu valley, not the real Himalayan area. I think "Border" is the town for Himalaya.

Explanation:
When did the Meakambut first encounter Australian government officials? Why do you think it took so long for such an encounter to occur?
Answer:
The Meakambut only found members of the Australian government in 1966. This meeting was slow to happen because the Meakambut are a very small group that have nomadic habits and like to stay in remote and difficult to find environments.
Explanation:
Meakambut is a very small nomade ethnic group. It is estimated that there are less than 60 people in the Meakambut group. In addition, they do not usually socialize with other peoples, as they have nomadic habits, making frequent trips and taking shelter in very remote environments. These habits hindered the contact between that people and the Australian government that only met in 1966.
Answer:
The Meakambut first encountered Australian government officials in 1966. The Meakambut have a small population and live in remote areas. These factors limited the chances of the Meakambut crossing paths with government officials.

Outline how differences in albedo contribute to differences in temperature between the equatorial and polar regions ?
Answer:
Differences in Albedo contribute to temperature differences between the polar and equatorial regions because areas with high albedo deflect off about 80% of the sun's radiation thus resulting in a cooler atmosphere whilst regions with a lower albedo are more heated thus resulting in a hotter or more tropical weather.
Explanation:
Albedo in Latin simply means whiteness. In geography, it is used to describe the extent to which the earth's surface absorbs deflects the sun's radiation. For example, an area covered with snow will most likely have a high albedo and the obverse is also true.
The laws of physics help us to understand that a black object has the capacity to absorb all the wavelengths of light hence, they absorb more heat. White objects on the other hand reflect all the wavelengths of light, hence they absorb the least amount of heat.
This is also true of geographical spaces. There are two major kinds of albedoes:
Terrestrial Albedo and Extraterrestrial (or Astronomical) Albedo.Terrestrial Albedo surfaces comprise fo the following:
Bare soil Conifer forest Deciduous forest Fresh asphalt Green grass Ocean ice Open ocean Worn asphaltAll the surfaces mentioned above have their albedo. The typical range is given as 0.9 for fresh snow to about 0.04 for charcoal.
In effect, if the entire planet were covered with snow, it would give rise to a global temperature of 0 degrees because all the light and it's heat energy would be reflected back into space.
If however, all of it were covered with water, the global temperature would stand at 27 degrees.

In the Green River and Price area, what fossil fuel would you expect to find there?
The type of map represented in the picture is a geological map. Geological maps show features such as soil and rock type and structural features such as faults. There are numerous faults represented on the map The main type observed are thrust faults. The area around Salt Lake is approximately between Quaternary to late Tertiary based on the map. The main geologic unit in this area is composed of alluvial, glacial and lake sediments. Middle Tertiary volcanic rocks can be found south of Richfield. Pre-Cambrian metamorphic (narrow outcrop east of the Great Salt Lake) and igneous rocks are the oldest represented on the map. The youngest rocks are Quaternary salt flats found mainly south-west of the Salt Lake. Intrusive rock outcrops can be found in different areas on the map. Outcrops can be observed southeast of Richfield, south-east of Ceder Clay and North of Lake Powell. Coal is the fossil fuel type present in the Green River and Price area.
