How the cell membrane structure of an arctic fish differ from tropical fish?
Arctic fish have a cell membrane structure that contains more unsaturated fatty acids to remain fluid in colder temperatures, while tropical fish have a higher proportion of saturated fatty acids to provide stability in warmer waters. Additionally, arctic fish may have specialized proteins in their membranes to help regulate their internal temperature in extreme cold environments.
Ascending unsaturated air expands or compresses?
Ascending unsaturated air expands as it rises due to lower atmospheric pressure at higher altitudes. Conversely, descending unsaturated air compresses as it descends to higher pressure levels closer to the surface.
Do you have facts about arctic bumblebees?
The Arctic Bumblebee (Bombus polaris) is found in Canada, Alaska, some of the Arctic Islands, Scandinavia and Russia. The Arctic bumblebee has dense fur that slows heat loss. These bees move their muscles quickly to warm their bodies. Also these bumblebees have a higher abdominal temperature than its temperate cousins.
How do membranes with low unsaturated lipids compare to those with high unsaturated lipids?
A high percentage of unsaturated phospholipids is more rigid. A low concentration is more flexible.
Would a larger mammal have a lower affinity for oxygen?
No, larger mammals tend to have a higher affinity for oxygen. This is because larger animals have a greater need for oxygen due to their higher metabolic rates, so their bodies have adapted to efficiently utilize the available oxygen.
What is the difference between saturated and unsaturated colors?
Saturated colors are vivid and intense, while unsaturated colors are more muted and subtle. Saturated colors have a higher level of purity and brightness, while unsaturated colors have a lower level of intensity and appear more washed out.
Why is the concentration of DDT in ring seals higher than the concentration in arctic cod?
The concentration of DDT in ring seals is higher than in arctic cod due to a phenomenon known as biomagnification. As DDT accumulates in the food web, predators like ring seals, which consume multiple prey species including arctic cod, accumulate higher concentrations of the chemical in their bodies. Additionally, ring seals may have a longer lifespan and greater fat storage, allowing more DDT to accumulate over time. This results in higher concentrations of DDT in ring seals compared to their prey.
Why is beef fat a solid at room temperature?
This is because it contains more saturated fatty acids then unsaturated fatty acids. Saturated fatty acids have a higher melting point then unsaturated fatty acids.
What are the producers in the Arctic Ocean?
Producers?
What is the food of mammals?
Different mammals eat different food. Mammals occupy varying places on a food chain. Some mammals are vegetarians, they are primary consumers. Some mammals are carnivores, they are higher level consumers. Some mammals are omnivores.
A plasma membrane is most fluid if it contains?
A plasma membrane is most fluid if it contains a higher proportion of unsaturated fatty acids in its phospholipid bilayer. Unsaturated fatty acids have kinks in their hydrocarbon tails, which prevents them from packing tightly together, making the membrane more fluid. Additionally, a higher ratio of cholesterol can also contribute to fluidity by increasing flexibility and reducing rigidity in the membrane.
