1. entomology
   zoology
2. mammalogy

The word is zoology, and this area of science covers the study of all things in the animal kingdom.

1. more than one million
   more than 10 million
2. more than 100 million

A whopping one million species have been identified -- and don't forget, we're referring to generic species, not animals within sub-species.

1. logical conjecture
   fossils
2. biblical reference

Fossil evidence indicates this.

1. homo sapiens
   mammals
2. fungi

The fifth one is fungi. These five kingdoms cover all types of living organisms.

1. because this is still a new field and scientists are studying it all the time
   because the organism is little known
2. because it may possess traits from more than one classification

Each kingdom is distinguishable by the traits of those within its classification, but some organisms possess traits from more than one kind.

1. is mobile during at least one phase of its life
   has fur, claws, paws, fins or blubber
2. can manufacture its own food through the processing of organic or inorganic matter

It has to be able to move about under its own power (be mobile) during a stage of its life, unlike plants and fungi.

1. organ, muscular and skeletal systems
   digestive, circulatory and respiratory systems
2. both of the above

Many bodily systems are present in all members of the animal kingdom. Those NOT mentioned yet include: integumentary, immune, excretory, endocrine, nervous and reproductory systems.

1. amphibians
   primates
2. reptiles

They're called primates. This group includes apes, monkeys and lemurs.

1. They possess something called adaptations, each animal with its own color, size, shape, etc. allowing itself protection.
   They have the characteristic of camouflage.
2. They all have venom or spikes, which affords them protection.

All animals possess adaptations. Each animal has its own adaptation in the form of camouflage, size, body shape or whatever, that protects it from predators.

1. nesting
   adapting
2. hibernating

This phenomenon is particular to warm-blooded creatures and it's called hibernating. They can do this because of their ability to adapt to environmental change.

1. 5,000 miles (8,050 kms)
   11,000 miles (18,000 kms)
2. 18,000 (29,000 kms)

They will migrate as far as 11,000 miles (18,000 kms) to find warmer waters for breeding.

1. antelopes and deer
   wombats and kangaroos
2. bears and bats

Bears and bats both instinctively choose this form of shelter for sleeping and raising young.

1. They leave manure and droppings around and this generates plant reproduction.
   They carry pollen from flower to flower to facilitate fertilization or they may spread seeds by carrying them in their fur.
2. They don't; this is a myth.

Some animals, such as birds and bees, carry pollen from flower to flower and this facilitates fertilization. Other animals spread seeds around by carrying them on their bodies or in their fur.

1. Each caste has its own lifespan and reproductive cycle.
   Each caste differs in body structure and performs different tasks.
2. Each caste is independent of the other and feeds on different foods.

Termites and ants have a discernible system of hierarchy. In this system, each caste has its own body structure and performs its own tasks.

1. mutualism
   commensalism
2. parasitism

Commensalism. A good example of this is barnacles that live on the backs of whales at no expense or harm to the whales themselves.

1. the study of animal behavior
   the study of early life forms
2. the study of predatory animals

Ethology is the study of animal behavior.

1. yes, usually
   rarely
2. absolutely not

In most cases, the animal will not be tempted to eat because it is satiated already. This is part of its instinctive food drive -- the drive to eat until satiation.

1. sight, taste and smell
   sight, smell and sound
2. smell, touch and sound

The senses of sight (vision), smell (scent) and sound (hearing) are all used for communication between animals.

1. They were experimented on.
   They were worshipped as gods.
2. They were hunted as food.

In certain ancient societies, animals were worshipped as gods. An example of this is ancient Egypt, which worshipped the cat and the lamb.

1. reptiles
   jungle animals
2. those that carry or cause disease

Animals that carry or cause disease are the most harmful to humans, causing thousands of deaths per year.
