Explian by taking three different examples how do certain organisms pull through the adverse conditions when unable to migrate under stressful period.

Text Solution

AI Generated Solution

To explain how certain organisms cope with adverse conditions when they are unable to migrate, we can look at three different examples: estivation, hibernation, and diapause. ### Step-by-Step Solution: 1. **Estivation**: - **Definition**: Estivation is a state of dormancy that occurs in some animals during periods of extreme heat or drought, typically in the summer. - **Example**: Snails are a prime example of organisms that undergo estivation. When the temperature rises and water becomes scarce, snails reduce their metabolic activity significantly. They may seal themselves in their shells with a layer of mucus to retain moisture and survive until conditions improve. ...

A reaction is spontaneous if free energy change DeltaG , for the reaction is negative . The question arises, how we can explain , the spontaneous of reversible reaction taking the example of dissociation equilibrium N_2O_4 hArr 2NO_2(g) the variation of free energy with the fraction of N_2O_4 dissociated under standard conditions is shown in the figure below. When 2 moles of NO_2 change into equilibrium mixture the value of DeltaG^@ is

Silicon is the second most abundant element (~27.2%) in the earth's after oxygen (45.5 %) Carbon. Silicon, germanium, tin and lead constitute the group 14 of the periodic table. Chemistry of silicon is distinctly different from that of carbon. For example, under standard conditions CO_(2) is a gas whereas SiO_(2) is a covalent solid. Draw the structure of the anion present in pyroxene (MgCaSi_(2)O_(6)) . Silicones are important synthetic polymers which find extensive applications due to their chemical inertness and water repelling nature. Thet are produced via the following reactions. 2 C_(6)H_(5)Cl +Si underset("370 K")overset("Cu")to A A underset(-HCl)overset(H_(2)O)to B
