Explanation:
Answer:
Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes.
Explanation:
Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.
Exoskeleton
Exoskeleton is a evolutionary innovation. This is operated by muscles attached to it and acts as an armor. Other than support this is an adaptive mechanism to provide protection against predators. In vertebrates, it is considered as the dermal bone that developed via membranous ossification. Fishes retained their exoskeleton in the form of their scales. However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,
Answer: What will happen to a cell if placed in a hypotonic solution?
A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis. These three examples of different solute concentrations provide an illustration of the spectrum of water movement based on solute concentration through the process of osmosis.
