If rabbits are introduced in an isolated grassland for the first time, which of the following growth curves (shown using dashed line) is/are theoretically possible population dynamics over time?
Correctly match the following Arabidopsis genes (Group I) and the biological processes they primarily regulate (Group II):
The following table summarizes the flowering time behavior (days to flower) and the transcript levels in four genotypes of a plant species.
Which one of the following genetic pathways best explains the observations shown in the table?
Correctly match the photosynthetic pathways (Group I) with their first stable products (Group II) in respective plants (Group III):
In the history of photosynthetic research, the empirical reaction of photosynthesis was first proposed for green plants (equation 1), followed by another reaction for purple sulfur bacteria (equation 2), leading to a generalized equation for photosynthesis (equation 3), where \( {H}_2{A} \) in equation 3 is a generalized electron donor.
\[ {CO}_2 + {H}_2{O} \xrightarrow{{light}} {(CH}_2{O)} + {O}_2 \quad {(equation 1)} \] \[ {CO}_2 + 2{H}_2{S} \xrightarrow{{light}} {(CH}_2{O)} + {H}_2{O} + 2{S} \quad {(equation 2)} \] \[ {CO}_2 + 2{H}_2{A} \xrightarrow{{light}} {(CH}_2{O)} + {H}_2{O} + 2{A} \quad {(equation 3)} \] Where \( {H}_2{A} \) in equation 3 is a generalized electron donor. Which one of the following statements is DISPROVEN by equation 3?
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
