I think the first statement is true; while the second statement is false. It is true that drinking sea water would cause a rise in the osmotic pressure of the extracellular fluid because sea water will be hypertonic (salty water) to the extracellular fluid therefore water will move from the extracellular fluid osmotically creating an a rise in osmotic pressure. The whole effect won't make water leave the blood capillaries.
Se cree que los humanos emigraron al norte de Australia desde Asia en botes primitivos. Una teoría actual sostiene que esos primeros migrantes salieron de África hace unos 70,000 años, lo que convertiría a los aborígenes australianos en la población de humanos más antigua que vive fuera de África.
Parthenogenesis is a method of reproduction in which D.an egg develops without being fertilized by a sperm. That's true due to the definition of parthenogenesis.
There are four nitrogenous bases that makes DNA. These are A, T, G and C. If a DNA strand has eight pairs of nitrogenous bases, the eight bases can be
1. AA GG TT CC
2. GC GG AT CG
3. AT TA GG GC
4. GA AG GC GG
Like this, there can be 65,536 different sequences with ATCG.
Since we have 4 nitrogenous bases, pairing will make 4 X 4 = 16 combinations. If we have to make 8 pairs of bases, the number of possible sequences would be 4 to the power 8.
Answer: THERE WILL BE 65,536 DIFFERENT SEQUENCES OF 8 BASES.
