Do you believe in animal research? can you give me some reasons? Do you think it is acceptable for scientists to perform research on animals like fruit flies, rats, mice, and rabbits?

1.A jar of tea is placed in sunlight until it reaches an equilibrium temperature of 32°C. In an attempt to cool the liquid, which has a mass of 180 g, 134 g of ice at 0°C is added. At the time at which the temperature of the tea (and melted ice) is 16°C, determine the mass of the remaining ice in the jar. Assume the specific heat capacity of the tea to be that of pure liquid water

Would it be possible to isolate and use the beneficial genes from this organism to engineer plants (food) that take on the beneficial traits of being heat/vaccuum/radioactive/cold resistance for possible use to grow in otherwise unhospitable environments? Thanks.

It's funny, but most of the pages on the net that one would find concerning the mystery of 0.9 repeater is constantly claiming that it simply equals 1. Which I frankly, disagree with, because easily demonstrated through the limiting sum...or calculus in general, 0.9 repeater approaches but never equals 1.
