The access is most heavily limited by Climate

In an extremely dry and hot climates such as desert, it will be incredibly hard to access potable water because they evaporate really quickly

Meanwhile in a wet and cool climates such as rain forest, it will be extremely easy to access potable water

Explain how seasons are similar and different on your Uranus as compared to the Earth.

Alisiya [41]

Answer:

Uranus, like Earth, has four seasons. ... For starters, the length of Uranus' seasons are different from ours. It takes Earth 365 days to orbit around the sun, but it takes Uranus 84 Earth-years, more or less. So Uranus' year is 84 Earth-years along, and each season on Uranus lasts 21 earthly years.

artcher [175]

<h2>Himalayas </h2>

Explanation:

Once, all the world’s landmass was connected, forming one super-continent known as Pangea
About 200 million years ago, tectonic forces broke apart this giant continent into pieces, eventually forming the continents that are known today
As convection currents worked independently on the plates associated with these new continental pieces, the plates and their respective continents began to drift across the globe to their present-day geographical locations
Eighty million years ago, India was approximately 6400 km south of the Eurasian plate, separating the two was the Tethys Sea
The Indo-Australian tectonic plate – containing the continent of Australia, the Indian subcontinent, and surrounding ocean – was pushed northward by the convection currents generated in the inner mantle
For millions of years, India made its way across the sea toward the Eurasian plate
As India approached Asia, around 40 million years ago, the Tethys Sea began to shrink and its seabed slowly pushed upwards
The Tethys Sea disappeared completely around 20 million years ago and sediments rising from its seabed formed a mountain range
When India and Tibet collided, instead of descending with the plate, the relatively light sedimentary and metamorphic rock that makes up the subcontinent of India pushed against Tibet, forcing it upwards, and created a massive mountain fold, The Himalayas
This process hasn’t stopped, the Indo-Australian plate is still moving toward Eurasia, still pushing Tibet upwards
The Himalayas continue to rise by an average of 2 cm each year and the highest mountains are only getting higher

dsp73

Answer:

The first attached figure below shows the design of an agarose gel with four sequencing reactions. The second figure presents a photo of an agarose gel, so that you can better understand how the bands are represented in this gel.

Explanation:

To view the bands of four sequencing reactions on an agarose gel, you will need to use a melted agarose gel, plastic combs suitable for that reaction and a container suitable for that type of gel. You will place the plastic combs in the container and pour all the gel into the vat and wait for the melted gel to solidify. The plastic combs will form holes in the hardened gel where the DNA samples will be placed.

Once the gel is hardened, you will remove the plastic combs and begin to apply the sequenced DNA.

The sequenced DNA samples will be mixed with a dye, usually bromophenol blue, which will allow you to visualize the bands formed on the gel. You will also apply the dye to a sample without DNA containing only the dye, which serves as a comparison for the size of the bands.

Each sample of DNA will be plated in the column of holes formed by the plastic combs. Then, this container, with the gel, will be placed in a larger container that contains a loading buffer. The larger container will be closed and an electric field will be applied that will force the DNA samples to be moved from one pole to another inside the container, in this case, the samples leave the negative pole for the positive pole.

After a few minutes, it is possible to visualize the DNA displacement and at the end of the procedure it will be possible to visualize the formation of bands as shown in the drawing and in the figure below. The size of these bands can be compared and analyzed.
