Interphase is the cell grows and makes a copy of its DNA's and in m phase the cell separates the DNA's and divide its cytoplasm, forming two new cells
Eukaryotic cells posses a nucleus the purpose of the nucleus is it stores DNA which is the genetic material for the cell DNA acts as an instruction manual for the other organelles in the cell. While prokaryotic cells do not have a nucleus they still have dna but it’s floating around freely
The word isotonic is used to refer to the solutions (two solutions) which have the same osmotic pressure in both sides of the semipermiable membrane. The condition allows the free movement of water across the membrane. However, this does not change the concentration of the solution across the membrane.
Hence, osmosis may not occur in this condition.
Birds, just like humans, have a four-chambered heart.
