In what way are frog and fish similar?

Both frogs and fish belong to the phylum Chordata and the subphylum Vertebrata. This means that both frogs and fish have a spinal cord and backbone. In addition, all chordates have bilateral symmetry. This means that they have a matching left and right side.

How is the breathing process of a frog different from that of a fish?

Frogs breathe through their skin and fishes breathe through gills.

How is breathing similar in a fish and a tadpole?

General Science fish breathe in water using gills. Water flows across the gills and blood is allowed to exchange oxygen and carbon-dioxide. Tadpoles breathe the same way as fish during that stage of life before maturing into frogs that use their lungs to breathe.

What are the similarities and differences of the respiratory system of human and frog?

Humans breathe exclusively through their lungs, but frogs use their lungs for only part of their respiration. Frog lungs have thinner walls and are almost like balloons. They often fill their lungs to help them stay buoyant when swimming.

How are frogs alike?

Frogs and toads are both members of the same class — Amphibia — which means that they’re both amphibians. Amphibians are cold-blooded vertebrates that spend the early part of their lives in water (breathing with gills) and the rest of their lives on land (breathing with lungs).

How are frog and toad alike?

They are both amphibians in the order Anura, which means “without a tail.” Toads are a sub-classification of frogs, meaning that all toads are frogs, but not all frogs are toads. They both reproduce in water, and they even look alike. Frogs usually have webbed hind feet, and some have webbed front feet.

How does frog breathe in water and on land?

In water, frogs exchange gases through its thin, moist and smooth skin which is richly supplied with blood capillaries. On land, frogs breathe through lungs.

What makes frogs breathe in water as a tadpole?

Tadpoles have gills that allow them to breathe during their underwater phase of life. The gills, which are usually covered with a flap of skin, are located on the side of their head. Along with gills, the tadpoles also develop lungs. These lungs help the tadpole breathe in water with a low oxygen concentration.

What are the similarities and differences of the circulatory system of human and frog?

Both creatures possess a circulatory system, which operates as the heart pumps blood throughout the body. However, frogs have a three-chambered heart, with two atria and one ventricle compared to the human’s two atria and two ventricles. Additionally, frogs and humans have similar digestive and respiratory systems.

How are humans and frogs similar?

Scientists found additional similarities between the frog genes and human genes. For instance, genes in frogs have very similar neighboring genes as humans about 90 percent of the time. In other words, the frog genome contains the same sort of “gene neighborhoods” as the human genome.

What do frogs have in common?

How do frogs Breathe Out of water?

gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air. A frog may also breathe much like a human, by taking air in through their nostrils

How is the respiratory system of a frog different from humans?

sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in. In order to draw air into its mouth the frog lowers the floor of its mouth,

How does repiration take place in a frog?

While completely submerged all of the frog’s repiration takes place through the skin. The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels.

What is the difference between air and water for fish?

Comparisons. Mammals and insects both get their oxygen from air, while fish get oxygen from water. Water has a much lower oxygen concentration than air, and is harder to ventilate because it is more viscous. This means fish need to have a more efficient gas exchange system to get enough oxygen from the water.
