Answer:
The major characteristic feature of asexual reproduction is the production of clones.Identical offspring with virtually similar DNA.Therefore,this is advantageous to the parasite because, the offspring or progeny produce are similar(clones), to the parent parasites,thus multiple reproduction can occur when a single individual parasites cells divisions.
Explanation:
There's a great picture that I attached below that is a great representation
The red blood cels are pushed through both systems and works as a avocet to the send signals that the heart is overworked and cant push enough blood to the need breathing
1. The Cell Wall.
Plants have a cell wall in order to maintain rigidity and stability. Animal cells do not have a cell wall because they have a different structure, which makes them more flexible and able to move around easier.
2. Chloroplasts
Since plants cannot move, they get their energy from the sun. This energy is made inside of the chloroplasts. Animal cells don't have chloroplasts because their energy comes from other organisms.
3. Central Vacuole
The central vacuole provides structure and holds materials and wastes, and also decomposes those wastes. Animal cells don't have a central vacuole because they have lysosomes and normal vacuoles that do the same function.
Well they can begin as cosmic rays colliding with water molecules to create clouds. Hope this helps :)
