Question

Life on Mars?
In 1976 two Viking spacecraft reached Mars. When they arrived each
spacecraft split in two. One part, called the Orbiter, travelled around the
planet taking photographs and measuring temperatures. The second part
called the Lander, touched down on the planet's surface. Although the
Lander measured the Martian weather and had equipment on board to detect
vibrations like earthquakes, the experiments that everyone wanted to know
about were the ones to test the soil for signs of life. There was great
excitement when one of the soil samples began to froth. It could have been
caused by something respiring - a sign of life. After a few weeks of further
investigation it was decided that the froth was most probably made by a
chemical reaction not connected to a living organism.
There are signs that water once ran over the planet's surface, so some
scientists believe that there could still be life there, but that it is buried
deeper in the soil than the Lander could reach.
In 1997 the Pathfinder probe reached Mars and a vehicle called the
Sojourner travelled around the landing site to take photographs and perform
tests on rocks. It did not have any experiments on board to test for life.
Further observations on the planet have shown that some water is
present. As living things need water there is a chance that when the water is
examined some life forms may be found.



Answer to these questions given below.

1 What were the two parts of the
Viking spacecraft and what
did each part do?
2 Why could the froth be a sign
that something was respiring?
3 What are the advantages and
disadvantages of bringing
back Martian rock to Earth to
look for organisms?
Can any of the disadvantages
be overcome? Explain your
answer.​

Answer 1

Answer:

A paradox is a statement that contradicts itself, or that must be both true and untrue at the same time. Paradoxes are quirks in logic that demonstrate how our thinking sometimes goes haywire, even when we use perfectly logical reasoning to get there. But a key part of paradoxes is that they at
