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 the concentration of ddt in ring seals is much higher than the concentration in arctic cod?
The concentration of DDT in ring seals is much higher than in arctic cod due to a process called biomagnification, where toxins accumulate at higher levels in organisms at higher trophic levels. Ring seals, being higher up the food chain, consume multiple prey items, which may contain DDT, leading to a greater overall concentration in their bodies. Additionally, seals have a longer lifespan and larger body mass, allowing for more significant accumulation of DDT over time compared to arctic cod.
What element has cable for a ring mains at 230v or higher?
Copper is commonly used for cables in ring mains operating at voltages of 230V or higher. Copper is a good conductor of electricity, allowing for efficient transmission of power, making it suitable for high-voltage applications.
Why is there no ring of fire in the Atlantic ocean?
The tectonic plates that occur where there is volcanic activity form a ring that almost completely encircles the Pacific Ocean. These teuconic plates are still moving and the pressure heats up the rock causing eruptions (volcanoes) that can occur at most points on the plates. That is why its called the ring of fire. Why is there no ring of fire in the Atlantic? There was at one time. The Icelandic Volcanoes are all that remains of a ring of fire that sculpted the coastlines of Norway, Sweden, Finland, Scotland, Ireland and Greenland. Iceland is largely a set of islands that emerged in the centre of that ring due to deposit of volcanic ash and cooling lava. The Giants Causeway in Northern Ireland is a set of Basalt pillars thrown up by Volcanic action. The North Atlantic ring of fire cooled over millions of years (Ice age and Arctic winters), which is why it is now restricted to a few very active volcanoes near the centre.
What is the belt of volcanic and seismic activity that borders most of the Pacific Rim?
The Ring of Fire is a belt of volcanic and seismic activity that borders most of the Pacific Rim. It is characterized by a high concentration of earthquakes and active volcanoes due to the movement of tectonic plates in the region.
Are volcanos scatered evenly or in concentrated zones?
Volcanoes are typically found in concentrated zones, such as along tectonic plate boundaries. These areas, known as the Ring of Fire, have a higher concentration of volcanic activity due to the movement and interactions of the Earth's tectonic plates. While volcanoes can occur in other locations, they are most commonly found in these concentrated zones.

Which animals are found in Arctic regions?
some animals are ring seals, polar bears, harp seals, leopard seal and some others.
With what other organisms do polar bears interact?
they meet other animals as they find prey, go hunting, and find other polar bears.
Where is the o ring located in the 2005 caravan airconditioning?

Do all 350 heads have valve seals?
The Chevrolet 350 stock "O" ring valve seals attach to the valves not the heads but, yes the head assembly has valve seals.
Can you use just umbrella seal on intake and exhaust valves instead of o ring type?
yes, you can use the umbrella seals. I just replaced my umbrella seals on my valves with new ones. My head gasket kit came with the o-ring seals though, I heard the umbrella seals were more preferred. I haven't had a issue since I replaced them.
