Sunday, July 20, marked 45 years since the United States put the first two astronauts safely on the moon. The cost for the Mercury, Gemini and Apollo programs was more than $25 billion at the time more like $110 billion in today’s world. The ensuing U.S. space efforts have cost an additional $196 billion for the shuttle and $50 billion for the space station. NASA’s total inflation-adjusted costs have been more than $900 billion since its creation in 1958 through 2014 (more than $16 billion per year). Looking back, have we gotten our money’s worth from the investment?

An adaptive trait: (mark all that apply)
snow_tiger [21]

Answer:

[a] varies in its characteristics according to local environmental circumstances

[b] becomes common within a species through natural selection

[d] tends to promote the well being of an organism in its natural or social environment

Explanation:

The adaptive traits in the living organisms have a simple basic role, that is to make the organism better suited for survival in its environment. The adaptive traits come in all sorts of different shapes, be it some that are manifested in the physical appearance or in the behavior of the organisms. Adaptive traits can be increased speed, prolonged neck, living in a groups, developing thorns and many more. This type of traits occur when the organisms face increased competition or when the environment in which they live starts to change, so in order for them to survive, they start to develop traits that will make them better suited for the new conditions and more competitive. The main principle through which the adaptive traits are transferred and rapidly increase in a population is through natural selection, as the organisms choose the ones that have advantageous traits for their mates, while they live aside the others.

Climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount
miss Akunina [59]

Answer:

Yes, that is very much true, just because climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount of heat radiated back into space by the Earth.

  • <u>Climate change:</u>

<em>"The change in stability of the environmental factors or the negative effects  in the equilibrium inside the environment is called as the climate change."</em>

  • <u>Global Warming And the green house effect:</u>

<em>"The overall rise in temperature of the earth spheres and its environment is termed as global warming, and its due the green house effect(the negative effect due to the increase level of CFC's)."</em>

  • <u>The trapped Sun radiation inside the earth's sphere:</u>

<em>"Due to large number of CFC's inside the earths sphere, as they results in trapping the radiation which needs to be radiated back out of the earth's sphere. Causing the rise in temperature of the overall environment."</em>

Explanation:

  • The chloro, floro and carbon elements which are also termed as the CFC's in general are created due increase level of industrial waste presence in the environment, leading to more solar radiation trapped inside the outer sphere of the earth's protective shield. Due, to this process the gasses are trapped inside the earth's sphere resulting in the rise in temperature.
  • <u>Consequences of Climate Change:</u>
  1. As our earth passed from various levels and situations and as there were also some ice ages, which almost resulted in creating inhabitable situations for the living beings.
  2. But, these days earth is facing some alarming situations in the form of high temperature in its environment, which is some how leading to some thing more worse.
  3. There will be less resources of food in the near future and most importantly there will be species like polar bears and some marine animals who will face extinction due to the rise in temperature inside the environment.
