What structure in fish performs the same function as lungs in mammals?
Gills
The gills perform the same function.
Which is more related to a human frog bat lobe-finned fish or alligators?
I'm not sure... I also want to know it because I have this exactly same question for my homework today.
That it is impossible for cats to snore. Obviously, shewas never woken up by my cat's snoring. The feline likely suffers from some sort of allergy or asthma problem that is made worse by the lack of movement while sleeping.
What type of consumer is a puffer fish?
Apart from the cartilaginous fish such as shark, almost all fish have a spine, therefore are vertebrates.
What kind of fish that eats wood?
Amazonian Panaquefish eat wood and have bacteria in their stomachs to help break it down
hope that helped
Plecco's also need bog wood to help digest their food.
Dangers faced by fishes in the river?
They must face predators, oil slicks and pollution which can lead to instant death or death by killing the things they eat. They also will face man made materials that may entangle them.
Good colors are chartreuse, and white. For plastics, however, the top producer color is green pumpkin.
Yes, dragonflies do have gills and a chin that can reach out like an arm and eat small fish. But grow lungs as they grow older, they are amphibians.
BONUS: THEY DO MUTATION
Why are your mollies killing everything?
Mollies are a group/schooling fish that can become restless if overcrowded by other species, or it's own, and attack, thus controlling the population of the tank. While peaceful, the molly can become aggressive and is teritorial.
Is there any food that Ospreys eat besides fish?
Ospreys feed almost entirely on fish, plucked from the water.
Most fish have swim bladders giving them buoyancy that allows them to "float" at various levels in water. While some species are surface dwellers other fish floating on the surface are deceased and float because of gases formed within their bodies due to the process of decay.
What problem caused biologists to believe amphibians evolved from certain fish?
The earliest forms of amphibians evolved from lobe-finned fish in the Devonian Period, around 350 million years ago. These fish had strong, bony fins that allowed them to drag themselves on land, and some of them developed lungs for breathing air. These two adaptations were very helpful in their freshwater environments that were often stagnant and dried out. Eventually the bony fins of these fish evolved into limbs that became better suited for terrestrial locomotion over time. Early amphibians still spent most of their lives in water and always had to lay their soft eggs in water.
One of the earliest and most well known ancestors of amphibians (and all tetrapods in general) is a lobe-finned fish called Eusthenopteron. Although it never actually went on land, it still had four fins with bone structures homologous to all modern tetrapods, and also had internal nostrils and enfolded enamel found on primitive labyrinthodont amphibians.
Another important transitional form is Tiktaalik, who is an important link in the transition between lobe-finned fish and tetrapods. By the structure of its jointed fins, which contain wrist bones, it was probably one of the first fish to crawl on land. However, it only did so under certain circumstances and still spent almost all of its time in water. It had both gills and primitive lungs, and had a flattened head shaped like that of an amphibian's.
The earliest amphibians include Acanthostega and Icthyostega. Their primitive limbs contained digits, but were still poorly adapted for moving efficiently on land. Yet it was a good start, and they would be succeeded by labyrinthodonts such as Tulerpeton and Eryops, who are the ancestors of true amphibians.
The first modern amphibians emerged in the Carboniferous Period and had all the adaptations necessary to make them suitable for living both in water and on land. Amphibians became the dominant terrestrial vertebrates through most of the Carboniferous until they are replaced by their descendants, the reptiles.
Do fish have segmented bodies?
Flies are in fact an insect that has a segmented body. Other insects with segmented bodies include ants and beetles.
The pH scale is made up of 3 parts:
- Acidic
- Basic
- Neutral
These 3 parts are represented on the scale in different points. The scale is like this:
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
A substance with pH between 1-7 is Acidic and on a universal indicator it comes up as the colour red or yellow.
7 is Neutral. A neutral is a substance like water it is neither acid or alkaline. It comes up as the colour green.
7-14 is Basic. It comes up as the colour blue or purple..
Examples:
- On the scale, if the pH is 1, it is an extremely strong acid this will be deep red.
- If it is 6, it is an extremely weak acid this will be a yellowish green.
- if it is 8, it is an extremely weak base and its light blue.
- If it is a 14, it is an extremely strong alkaline and its dark purple.
