The Difference Between

The difference is the life cycle, size of the worm and the kinds of damage each type can do. Pinworms are small worms and are generally more irritating than anything. They cause severe itching around the anus because their life cycle includes the female worm exiting the body and laying eggs on the skin around the anus using a very irritating substance to glue them in place. Roundworm, on the other hand, can grow to be very large and can cause severe damage to the lungs, because their life cycle includes migration through the lungs before they mature. Once mature, they can be a cause of malnutrition and impaction in the gastrointestinal tract. In animals (and humans) that are not their normal species to infect, some roundworms can enter the body and migrate through the eyes, brain, lungs and liver and cause damage to those organs. This is generalized information because there are many types of roundworms and pinworms, but it gives an idea of the differences in the two.

Grasshoppers have spiracles that help them breath whereas crayfish breath through gills.

hyphae is a brown seaweed that has holdfasts.

aka hookweed.

Well ones a bit bigger than the other

A spider lives in a web and a caterpillar is a ground species like a grub.

It might just be semantics. The words can pretty much be interchanged (and often are), but the difference is probably that a factory may have several plants within its manufacturing complex. A car factory might have an engine plant and an assembly plant as well as a bunch more other plants, each of which puts together a subassembly of the vehicle. It is not surprising that if the definition of each work is looked up, the other word is often applied in that definition of that word.

In mutualism, both organisms win... like the bacteria in our guts, they break down food so we can absorb it, and we feed them. Win-win.

In parasitism, one organism wins at the expense of the other. Take tape-worms, like bacteria, they can live in our guts, we feed them, but they provide NOTHING of value to us and instead actually hurt us.

isopods have 7 pairs of legs but beetles have 3 pairs of legs

They have 4, but not exactly "fingers"

A bearded collie is much bigger than a border collie and the bearded collie has longer hair than the border collie.

No. The Andalusian and Lipizzan horses are different breeds. They are closely related, but are distinct breeds with separate breed registries.

The International Andalusian and Lusitano Horse Association has a website, so does The Lipizzan Association of North America.

well gators have a u-shaped mouth but crocs has v-shaped they both hunt and crocs are more dangerous.

A turtle can only stay out of water for a short amount of time, a tortoise can stay out of water for a long time depending on how sensitive their skin is.

A drake is a male duck.

"Joey" is the term for all young marsupials. These animals feed solely on mother's milk for the first 3-8 months of their life, depending on the species.

Kangaroos are herbivores, primarily eating grass and other vegetation, feeding in the early morning and late afternoon/evening towards sunset. Besides grass, they eat young shoots and tender leaves of native shrubs. They enjoy grains as well, but being herbivorous, they do not eat any other animals.

Tree kangaroos eat leaves, and sometimes fruit.

If living in captivity, kangaroos have access to a greater variety of vegetation and grains such as corn. Whilst kangaroos do need water, they can go for some time without direct water, as long as they have enough access to green plants, from which they obtain most of their moisture needs. Without sufficient water, they must move to better grazing grounds.

Smaller varieties of kangaroos such as the musky-rat kangaroo are omnivores, eating fruits, seeds, fungi insect larvae and small invertebrates such as grasshoppers and beetles.

Dogs can get sick just like all of us. We share many diseases, such as: Albinism, Ataxia, Deafness, Glaucoma, Hypothyroidism, Epilepsy, and even cancer. Some diseases only dogs have such as: Hip and elbow displaisia, Shar-pei fever, Pug dog encephalitis, and Lick Glaucoma.

well, a shark bite is usually created by a shark (when it bites you) and a crocodile bite is usually created by a crocodile.

To know if its a male or a female you can look at their color the male is a tanish white and the female is a light brown sometimes darker than that. Another way to tell is the female makes a monkey-ish noise and the male coo's very pretty and very often.

From an external heat source like the sun.

Male iguanas are typically larger than females.

Well the grasshopper, bee and beetle are all alike one because obviously they are all animals which are insects and two because they are all insects that have chewing mouth parts. So mosquitoes, moths, butterflies, flies and so on are insects that have sucking mouth parts, where as the ants, bees, wasps, beetles, weevils, grasshoppers, crickets and so on eat by biting and chewing not sucking.

A spider is neither a mammal nor an insect; it belongs to the class Arachnida. Spiders have eight legs and lack the wings and antennae characteristic of insects. Mammals, on the other hand, are warm-blooded vertebrates with fur or hair and typically produce milk to feed their young. Thus, spiders are distinctly different from both mammals and insects.
