Charicteristics of the thermosphere

Biology
1 answer:
marusya05 [52]3 years ago
4 0

Answer:

thermosphere(80 - 480 km from Earth's surface)

Explanation:

characteristics

- cloudless and free of water vapour

- the phenomenon of aurora is seen in this layer

- the bottom part of the thermosphere is known as the ionosphere

- the ionosphere has very high temperatures due to the presence of charged particles or ions. The ions function as a reflector of electromagnetic waves in long distance telecommunications.

Some have speculated that the origin of life occurred at geothermal vents. amino acids can form there. compared to the amino aci
cluponka [151]

There are a number of amino acids that have formed under certain environmental conditions if the required elements are present and the energy conditions ar compatible with chemical assembly. These conditions have also allegedly formed amino acids on meteors, asteroids and comets.


But, amino acids are a very minor component of more complex biochemical assemblies required for life. Pentose sugars are also required, which form under different environmental conditions than amino acids. More importantly, only left-handed homochiral amino acids and right-handed homochiral sugars can form functioning biochemical assemblies that are viable in an organism. But, natural conditions, like hydrothermal vents only produce racemic versions of sugars and acids, meaning they are always approx. 50% left and right handed. This is fatal to forming viable biochemical assemblies.


Further, it is not possible for all of the 20+ homochiral amino acids needed for a living organism to form naturally. The only ones found have been the simpler amino acids. Also, the 4 critical nucleotide amino acids, C, G, A, T, do not form naturally, are not homochiral, nor in the right proportions.


The geo/hydrothermal vent conjecture is nonsensical. These are open systems, susceptible to currents, mineral contamination, salinity, ph, and temperature, making them a totally unacceptable environment for the precise and exact placement of elements to assemble to form life.

Which of the following is likely the direct source of energy to move the sailboat? A, sun B. Wind. C. Moving sails D, Moving wat
ser-zykov [4K]
The direct source of energy to move the sailboat is probably wind, since wind is what pushes the sail of the sailboat, which is what propels the sailboat forward. 

Hope this helps!

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.
