Water diffuses from the lumen into the interstitial space during the reabsorption of water in the proximal convoluted tubule due to an increase in the interstitium's osmolarity.
Reabsorption is the process by which water and solutes from the PCT are injected into the blood. From the proximal convoluted tubule, the solutes and water go to the interstitium before entering the peritubular capillaries. The majority of the solutes and 99 percent of the water filtered by the nephron must be reabsorbed; all of these chemicals were "absorbed" in the digestive tract. The peritubular and vasa recta capillaries return reabsorbed fluids and chemicals to the circulation.

Answer:
1. Option D. 2. Option A.
Explanation:
1. Every individual has some unique characteristics and therefore, their ability to think and interpret things is different from each other. Hence, every individual concludes things on the basis of his/her own experiences, thinking, thoughts, etc.
Therefore, when two scientists get different results while studying the evolution of the universe then it is likely that they will get different results because both of them will have their own style of identification, hypothesizing things, or situations.
Thus, we can conclude that the two groups of scientists got different results because they had different specialties and interpreted their data differently.
2. It is the Chandrasekhar limit which gives an idea about the formation of the white dwarf, neutron star, or black hole at the last stage of a dying star.
The Chandrasekhar limit is equal to 1.4 solar masses.
As per the Chandrasekhar limit, if the mass of the dying star is less than 1.4 solar mass, then it will become a white dwarf.
If the mass of the dying star is greater than 1.4 solar mass, then a neutron star or black hole is formed.
Hence, the correct answer to this question is mass.
The reason why it takes a long time to develop a new variety of tomato is because changes in traits happen gradually, over many generations. The correct answer is A.
