Which group has 4 extraembryonic membranes- aquatic animals or land animals?
Land animals have four extraembryonic membranes: amnion, chorion, allantois, and yolk sac. Aquatic animals typically have fewer extraembryonic membranes as they rely on the water environment for support and protection of their embryos.
Are zooplankton protists?
No, zooplankton are not protists. Zooplankton are a diverse group of small animals that drift in aquatic environments, while protists are eukaryotic microorganisms that can be both single-celled or multicellular, but are not classified as animals.
What is the scientific name for the group of animals that can live both on land and in water?
The scientific name for animals that can live both on land and in water is "amphibians." They include frogs, toads, salamanders, and newts. Amphibians typically have moist skin and undergo metamorphosis during their life cycle.
What are different animals in the sponge group?
Animals in the sponge group, known as phylum Porifera, include various species of sponges such as sea sponges, glass sponges, and demosponges. These animals are multicellular but lack true tissues and organs, with specialized cells performing different functions within their bodies. Sponges are filter feeders that live in aquatic environments, ranging from freshwater to marine habitats.
Molecular phylogenies show all land plants are a monophyletic group This suggests that . A. there was a single transition from aquatic to terrestrial habitats B. land plants have undergone?
A. there was a single transition from aquatic to terrestrial habitats.
Which group has 4 extraembryonic membranes- aquatic animals or land animals?
Land animals have four extraembryonic membranes: amnion, chorion, allantois, and yolk sac. Aquatic animals typically have fewer extraembryonic membranes as they rely on the water environment for support and protection of their embryos.
Is a frog an amniote?
No, frogs are not amniotes. Amniotes are a group of vertebrates that possess extraembryonic membranes, such as reptiles, birds, and mammals. Frogs belong to a different group of vertebrates called amphibians, which do not have these extraembryonic membranes.
Is fish a aquatic animal?
Yes, fish are aquatic animals that live in water. They have adapted over time to thrive in various aquatic environments such as oceans, rivers, and lakes.
What is the difference between ichthyology and fish and fisheries?
Ichthyology is the study of the group of animals called fish. Fish are a group of aquatic animals with fins. Fisheries are entities engaged in the controlled harvesting of fish, generally for food.
Are zooplankton protists?
No, zooplankton are not protists. Zooplankton are a diverse group of small animals that drift in aquatic environments, while protists are eukaryotic microorganisms that can be both single-celled or multicellular, but are not classified as animals.
Are aquatic animals porifera or coelenterate?
Not all aquztic animals are porifera or coelenterate. There are molluscs, crustraceans, and even mammals amoung them. Porifera consists of all the sponge species and Coeletrata is a vast group consisting of hydra, cnideria etc.
What is another term for sea cow?
Sea cows are a group of fully aquatic mammals that live in swamps, rivers, and marine wetlands. These completely herbivorous animals are commonly called Sirenia.
What major group does the humpback whale belong to?
aquatic mammals
What molecule makes up cell membranes?
Cell membranes are mainly composed of phospholipids. A phospholipid is a phosphate group with a fatty acid tail. Proteins are also present in cell membranes.
What is a Coelenterate?
A group of primitive aquatic animals that include jellyfish, corals, and sea anemones. Colenterates are sessile (sedentary) and exhibit symmetry. Their body parts are symmetrically arranged around a central point.
What vertebrate group is a dolphins?
mammal
What is a sterol?
Sterols are a type of lipid molecule found in cell membranes. They are important for regulating membrane fluidity and permeability. One common sterol in animals is cholesterol.
