Question 6 (1 point) The function Square replaces each element of a list of integers with the square of that element. For example, when this function receives [2,0,-3] as input, the output will be [4,0,9]. Incomplete code for Square is given below. def Square (A): for i in range(0, len (A)): #FIX ME# return A What should the line of code which contains the expression #FIX ME# be replaced with in order to complete the code? A[i] = A[i]**2 i = A[i]**2 A[i] = i**2 i = i**2

What property of the element silicon has led some biologists to propose that silicon-based (rather than carbon-based) life-forms may have arisen on other planets? The number of valence electrons in silicon is the same as carbon, which means that the number of covalent bonds formed would be the same. Silicon is liquid at room temperature and therefore can act as a medium in which other chemical reactions can occur. Silicon is one of the fundamental building blocks of life on Earth currently and so could play a larger role on other planets. The electronegativity of carbon and silicon is exactly the same meaning they both form polar covalent bonds.
