Think and compare.
Comparison of overall equations of photosynthesis show that to some extent, two process are reverse of each other.

Some Mendelian crossing experimental results were shown to the students. Teacher informed that there are two genes located on the same chromosome. He inquired if they will be ever separated from each other?

Two long conductors, separated by a distance d carry current I_(1) and I_(2) in the same direction . They exert a force F on each other. Now the current in one of them is increased to two times and its direction is reversed . The distance is also increased to 3d . The new value of the force between them is

In a plant tallness is dominant over dwarfness and red flower is dominant over white.Starting with the parents work out a dihybrid cross.What is standard dihybrid ratio? Do you think the values would deviate if the two genes in question are interacting with each other?

Two long conductors separated by a distance 50 cm carry current I_(1) and I_(2) in the same direction. They exert a force F on each other. Now the current in one of them is increased to two times and its direction is reversed. The distance is also increased to 1.5 m. The new value of the force between them is

Apparatus: Two plastic bottles, measuring cylinder, thermometer, etc Chemicals: Potassium nitrate, sodium hydroxide, water, etc. (Sodium hydroxide being corrosive, handle it carefully in presence of teacher.) Procedure: Take I 00 mL water in each of the two plastic bottles. Plastic being insulator of heat, the dissipation of heat can be prevented. Note the temperature of water in the bottles. Put 5 g potassium nitrate (KNO_3) in the bottle and shake well. Note the temperature of the solution formed. Put 5 g sodium hydroxide (NaOH) in the other bottle. Shake the bottle well. Note the temperature. In the first bottle, the process of dissolution of potassium nitrate took place while in the second bottle, the process of dissolution of sodium hydroxide took place As per your observation which one is exothermic process and which is an endothermic process?

The two processes are reverse of each other to some extent. Photosynthesis involves reduction of CO_2 and respiration involves the oxidation of glucose. Explain.

When two cells of emfs. E_1 and E_2 are connected in series so as to assist each other, their balancing length on a potentiometer is found to be 2.7 m. When the cells are connected in series so as to oppose each other, the balancing length is found to be 0.3 m. Compare the emfs of the two cells.

Two wires of the same material and of the same length are stretched by longitudinal force, each of the some magnitude. Compare the extension, produced if the radius of the first wire is twice the radius of the second wire

A' is the largest structure of brain. It is enclosed in upper part of skull 'B' and covered by membranes 'C'. It shows two hemispheres internally connected to each other by 'D'. Write the names of A,B,C and D.

Two boys stand close to a long straight metal pipe, at some distance from each other. One boy fires a gun and the other hears two explosions with a time interval of 1 s between them. If the velocity of sound in metal is 3630 m//s and in air is 330 m//s , then the distance between the two boys is
