Frogs

Yes, frogs exhibit bilateral symmetry. Cephalization is the concentration of nervous tissue at one end of an organism. The frog has this nervous tissue (the brain) at the anterior end of the body (the head.)

the jelly like substance serve the purpose of protecting the eggs and also to keep it together. The jelly like substance also protect the eggs from water.

You measure your horse at his withers. I've come across many people who think that you measure the horse at his poll when his head is as high as it can go. Measuring a horse at it's poll. Correct: Measuring at his withers. You've probably heard people say something like this: "My horse is 15.3hh." The "hh" part means "hands high." What is a hand? That is the unit that you measure your horse in. Each hand is equal to four inches. So, lets say [beware, we are doing very easy math, nothing to sweat about]: Your horse is 9 hands. Each hand = 4 in. So, we would do: 9 hands x 4 in. = 36 inches. So, if your horse is 9 hands, he is 36 inches.

Frogs don't breath through gills. They breath through there nostrils but as young tadpoles they have gills and through the process of metamorphosis they grow lungs and loose their tails and grow feet.

No. They are vertebrates, but Leopard frogs are ectothermic, not endothermic. All frogs are ectothermic, which is commonly referred to as 'cold-blooded'. Frogs are amphibians, and all amphibians are ectothermic, as are fish and reptiles. Their body temperature is dependent on external environmental conditions.

They are in a pre- stage of mating wich means that the male is holding on to the female. They are not having sex - the male clamps the female so no other males can fertilise her eggs when the female deposits them. Only during this moment - the so-called spawning, the males will deposit their sperm.

Hey

A food chain of a grasshopper grass snake frog and hawk looks like the consumers are at the top which are snake and hawk. The snake and the hawk eat the grass the grasshoppers the frog.

The grasshopper eats the grass, the frog eats the grasshopper, the snake eats the frog, the hawk eats the snake. That's how the grasshopper snake grass frog and hawk food chain web works.

Hi there frog are amphibians this means they live o land and in water.Frogs eat flies and insects as there main diet , they husnt these bby flicking there long tongue out and sticking the insect to it by use of sticky syliva.The lay eggs called frog spawn up to numbers of 200 and then they hatch into tadpoles then eventually more frogs.

The atrium of a frog is part of the heart and is located on the upper chamber of the heart, also known as the auricle. It receives blood that has circulated through the body and is about to be pumped to the lungs or skin for oxygenation.

Well a bell frog has cold blood and does not like warmth; it lives in Antarctica.

In proportion to the size of the creature, the cricket jumps further.

Well depnding on the speices, but most of them swell up a little and go into the more shalow water and lay a clutch of eggs, after about 1-2 weeks the eggs hatch into tadpoles.

There are three chambers. One collects blood from the body and pumps it into the middle chamber. This pumps blood both to the lungs and to another chamber which pumps the blood back through the body. The major difference between this and a human heart is the mixing of blood from the body and blood from the lungs. In humans the lungs have their own separate circulatory system and there is no mixing of blood. This is because humans are warm blooded and need more Oxygen than a cold blooded creature requires. Blood leaving the human heart is fully oxygenated. Fish, frogs and reptiles have blood which is just partially oxygenated, because of the mixing of blood in their hearts.

FYI: the human heart develops from a two chambered (fish) and then a three chambered (frog) design in the embryo. The middle chamber is eventually split into two chambers by a muscular sheet of tissue called a septum. One congenital defect is an incomplete development of this septum before birth. The infant is born with "hole in the heart disease". The mixing of blood severely limits the Oxygen in the blood and these infants are also called "blue babies" because of their skin color. Open heart surgery was perfected decades ago and this condition can be corrected.

I had always thought that a complete metamorphosis involved a pupae stage. The argument that a froglet, being just a smaller version of an adult frog, might lead one to believe that humans (post natal) undergo a similar bypass of the pupae stage, in that as human babies, they do resemble humans, but are grossly dissimilar in proportion, human's baby's heads being about 1/3 of their total body length.
Incomplete.

Tadpole

lysosome

The goby fish can sometimes resemble a tadpole due to its elongated body shape and small fins. They are small, bottom-dwelling fish found in coral reefs and rocky areas.

Frogs can be VERY aggresive when it comes to their eggs. I would warn you NOT to touch a frog's eggs or you will be sorry.

They can breathe with lungs and can perform oxygen exchange through their skin when moist. Well I theorize that when they hibernate, they go underwater into the mud at the bottom of ponds. Now how is a frog to breathe underwater? while underwater their oxygen requirements are low, but they still need it. That is why they can also perform oxygen exchange through their skin. probably because they're amphibians.

No, because the genes of that quality is already there. it just isn't ready to undergo it.

The most important temperature, the second is light intensity

Yup. Sure do. So do toads. Catch one and hold it in your hand. You'll see. Been there, done that, got peed on.
