Which one of the following structural formulae of two organic compounds is correctly identified along with its related function?

Assertion : The only product of light reaction required in dark reaction are NADPH₂ and ATP  in C₄-plants.
Reason: Dark reaction occurs in night only.

A rectangle with sides 2m – 1 and 2n – 1 is divided into squares of unit length by drawing parallel lines as shown then number of rectangles possible with odd side lengths is

Using permutation or otherwise prove that is an integer, where n is a positive integer.

Find two values of k such that the points (2,-3), (3,0),(4,k) are collinear.

The sum of the first four terms of an A.P. is 56. The sum of the last four terms is 112. If its first term is 11, the number of terms is

Here we used the concept of Arithmetic progression to find the number of terms in the given series. When we study Arithmetic Progression, which is associated with: There are two key formulas we encounter, those were nth term of AP and sum of the first n terms. So therefore the number of terms in this AP is 11.

The sum of all two digit numbers which when divided by 4 leaves 1 as remainder is

Here we used the concept of Arithmetic progression to find the number of terms in the given series. When we study Arithmetic Progression, which is associated with: There are two key formulas we encounter, those were nth term of AP and sum of the first n terms. So therefore the sum is 1210.
