The correct answer is Protozoa.
A class of single-celled, non-prokaryotic organisms known as protozoa.These could either be parasitic or free-living in nature. These are heterotrophs that procreate via binary fission in an asexual manner. Numerous unrelated or tangentially related organisms make up the Protozoa. Sarcodina, Flagellates, Ciliates, and Sporozoans are the four main divisions. There are two stages in the life cycle of certain protozoa: the proliferative stage (trophozoites), and the resting stage (cysts). Trophozoites are the proliferative stage of the protozoa, which is when they divide and reproduce. The protozoa can tolerate adverse environmental circumstances like toxic chemicals, intense heat, and nutrition and water shortages because of their resting cyst shape.

Answer:
Though ice and snow are both made up of water, there is a difference between the two. Snow is nothing but the frozen atmospheric vapour which falls in winters on earth as light flakes whereas ice is simply frozen water.
First, a complete digestive system means that the digestive tract has a beginning or the oral end and the opposite end or the aboral end. This is found in more complex animals starting from roundworms (flatworms have an incomplete digestive tract). A closed circulatory system is found in animals more recent than mollusks. The presence of the coelom makes it more evolved than the flatworms.
Specifically, a small animal with a segmented body, short stiff appendages, and soft skin with the above characteristics point out to the phylum Annelida or annelids.
number 1 is not part of the theory of evolution.
Evolution is change in the heritable characteristics of biological populations over successive generations.
An animal that only eats meat is called a carnivore
An animal that eats both meat and vegetation is called an omnivore
An animal that only eats vegetation is called a herbivore
