What type of land animals are able to exchange oxygen and carbon dioxide through their skin?

Amphibians, such as frogs and salamanders, are able to exchange oxygen and carbon dioxide through their skin. Their skin is thin, moist, and highly vascularized, allowing for this gas exchange to occur.


Can manometers be used to record any metabolic gas exchange?

Manometers are typically used to measure pressure, so they are not commonly used to directly measure metabolic gas exchange. For recording metabolic gas exchange, methods such as gas analyzers or respiratory gas exchange systems are more commonly used because they can measure specific gas concentrations in exhaled breath.


Is lancelet living or nonliving?

A lancelet is a living organism. It is a type of marine invertebrate with a simple body structure, similar to that of a fish. Lancelets are considered living organisms because they exhibit characteristics of life such as growth, reproduction, and response to stimuli.


Why is water always lost from the gas exchange surface?

Water is lost from gas exchange surfaces due to evaporation. As gases diffuse in and out of the surface, water molecules also escape in the process, leading to its loss. This water loss helps maintain the concentration gradient necessary for efficient gas exchange.


The relationship between the animal's type of gas exchange system and it's environment?

An animal's type of gas exchange system is influenced by its environment. Animals in aquatic environments may have gills for efficient gas exchange with water, while terrestrial animals often have lungs to extract oxygen from air. Some animals like insects have a tracheal system for gas exchange that connects to almost every cell in their body. The type of gas exchange system an animal has is adapted to meet the specific oxygen requirements and environmental conditions of its habitat.
