What is a species found in the Platyhelminthes phylum?
There is no specific scientific name, there is only a Greek root word.
What are the daptation of a rain forsest frog?
Some rainforest frogs do not need water for their offspring. They lay their eggs in a moist environment and the little frogs develop completely in the egg, without a freeliving larval stage.
What is the process of asexual reproduction in freeliving flatworms?
Flatworms are one of the few animals that have the capability to produce sexually or asexually. To reproduce asexually, they must split and regenerate using a technique called binary fusion.
What are the four primary structural differences between a free-living flatworm and a parasitic flatworm?
Parasitic flatworms have to have a host. A free-living one doesn't.
Classification of Organism?
Taxonomists, biologists who specialize in the field of classification, use several categories when classifying organisms. A domain is the highest level of organization. Within a domain, there are kingdoms. within kingdoms, there are phya. within phyla are classes. within classes are orders. within orders are families. families contain genera (singular genus). finally, one genius contains one or more species.

What is a hair snake?
It's to gobble up oil its made out of hair they use it in the big oil spills========================================================================================================Nature Bulletin No. 101 February 1, 1947Forest Preserve District of Cook CountyWilliam N. Erickson, PresidentRoberts Mann, Supt. of ConservationHAIR SNAKESFarm boys have more fun than city boys. Every farm boy has watched the "hair snakes" sometimes found wriggling in drinking troughs for horses and cattle, or in puddles on a country road. They and their fathers will argue obstinately that these are hairs, from a horse's mane or tail, that turned into snakes. Phooie.Hair snakes are not snakes at all. They are roundworms. There are four common groups of worms here: annelids, which include earthworms and sewage-sludge worms; tapeworms; flatworms; and roundworms. The last three are called the "Lower Worms" and many of them are parasitic in other animals.The adult hair snakes, called "Gordian worms" by biologists because frequently found in tangled masses suggesting the Gordian knot of mythology, do resemble animated horsehairs or fine wires. They are covered with a thick tough skin and feel like the wet gut leader on a fishing line. They have a pair of eyes and many fine bristles along the body which are sensitive to touch. Having no mouth, they cannot eat although they may live for weeks or even months. They are freeliving -- only in the young stages are they parasitic.The female lays a white thread-like string of eggs, sometimes several feet long and containing millions of tiny eggs, often found along the shores of streams and lakes, or on aquatic plants. After hatching, the tiny young bores its way into some aquatic insect such as the mayfly larva where it passes through one stage of its development. It may remain there until the insect is eaten by a beetle or a fish. Or, if the insect dies, it may find its way into the body of a grasshopper, a cricket, or a beetle, where it completes the second larval stage and becomes an adult worm.If this second insect "host" falls into a brook or pond, the worm breaks through the body wall of the insect and seeks a mate. Otherwise it breaks through, falls on land, and may be swept into a body of water, or a puddle, by rain. Once we saw two boys, both sons of zoologists, having a swell time dropping grasshoppers into a tub of water and betting on whether a hair snake would emerge, thus completing the cycle.
What is the importance of living a healthy lifestyle?
The Importance of a Healthy and Clean EnvironmentEveryone wants to stay healthy and no one wishes to get sick at all times: that is why you too do everything to make sure that the environment you live in is clean, by sanitizing and sterilizing the things that you use on a daily basis and defending your home from pests. However, many people out there choose to spend a fortune in buying different solutions to ensure that they achieve such results.Illness-freeLiving in a home that is clean means that you and your family members are very likely to be free from unwanted illnesses, because, believe it or not, dirt is what attracts pests, which are responsible for causing many diseases. In fact, if your environment is unkempt, different bugs and mosquitoes may thrive in it. Mosquitoes are great bearers of sickness: just think that some of them are so dangerous that they have taken millions of lives worldwide.However, if you are going to thoroughly clean your environment - even the hidden parts and corners of the house, you are assured that those unwanted bugs will not harm or put your family's health at risk.Relieves you from emotional stressLet's face it, you feel worried even when a casual friend of yours is sick. They may pass their illness to you, or to one of your family members. But how much burden to your emotions it would be if the person involved is one of your children, a relative or a close friend? It will surely stress you out emotionally. Now remember that emotions play a big role in the entire human system. Emotional stress leads to anxiety, then to depression. Later on, you may lose your appetite, sleeplessness, restlessness and the list goes on. Having an ill member of the family creates a domino effect. On the other hand, you can definitely prevent this from happening. You just have to keep your environment clean.Saves you from financial burdenWith the unpredictable status of the economy these days, the last thing you want to be doing is to spend a hundred bucks in medicines and hospitalization. In fact, not everybody has the privilege of being covered by medical insurance. But also in that case medicines would cost so much you'd have to pay for them yourself. Well just think that you can save more and spend your money in other things if you just keep your surroundings cleansed and sanitized.Time is goldMoney can be replaced and health can be restored in most cases. But what with time? You are familiar with the phrase, "Time lost is time wasted". It is so true. When you get sick, you spend time resting because you have no energy to do your work. The hardest part is that time can never be replaced and restored anymore. Make full use of your time in things productive. Clean your environment and maintain it that way.Another wise quote is, "Prevention is better than cure". By keeping your environment clean and healthy at all times you have just saved your own life and that of the people around you.
