Theory of Evolution
The evolution of life is a gradual process through which simple organisms are transformed into complex life forms over billions of years. It involves genetic changes, adaptation to the environment, and the emergence of diversity in species. Fossil records provide evidence of extinct life forms and transitional stages. Evolution is influenced by factors such as mutation, genetic recombination, and environmental pressure, shaping the biodiversity we see today. Charles Darwin and Alfred Russel Wallace were pioneering naturalists who developed the theory of evolution by natural selection.
Alfred Russel Wallace, a naturalist, arrived at conclusions similar to Darwin while working in:

If \(A=\left[\begin{array}{ccc}2 & -3 & 4 \\ -3 & 5 & x \\ 4 & 3 & 0\end{array}\right]\) is a symmetric matrix and \(B=\left[\begin{array}{ccc}0 & 2 & -10 \\ -2 & z & 6 \\ y & -6 & 0\end{array}\right]\) is a skew-symmetric matrix, then the value of \((x y+y z+z x)\), is:

The number of vectors of unit length perpendicular to both the vectors \(\vec{a} = \hat{i} + 2\hat{j} + 3\hat{k}\) and \(\vec{b} = \hat{i} - \hat{j} + 3\hat{k}\) is:

The reaction \(2 N_2 O _5(g) \rightarrow 2 N_2 O _4(g)+ O _2(g)\) is a first order reaction.
It occurs at constant volume. Calculate the rate constant if the total pressure is 0.8 atm initially and the total pressure becomes 1.0 atm after 100 s

Consider the following hypothesis \(H_0: \mu=315\) and \(H_a: \mu \neq 315\).
A sample of 60 provided a sample mean of 324.6 . The standard deviation ( \(\sigma\) ) is 14 and level of significance \(\alpha=0.05\). Then the confidence interval is :
