A. Water+ carbon dioxide (light) > sugars + oxygen
Plants, Dinosaurs and bugs.
Because a spring is from where the water table is too high
Four new haploid cells are formed once the sister chromatids within the two daughter cells separate, forming four new haploid gametes.
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years.
The original mass is 30 g and the new mass is 3.75 g.
New mass = Original mass × (1/2)^n, where n is the number of half lives;
3.75 = 30 × (1/2)^n
1/8 = (1/2)^n
n = 3
Thus, the time taken will be; 3 × 5500 = 16500 years.
