Answer:

As many as 30 thousand fur seals become entangled in lost or discarded fishing nets or cargo straps each year.

Explanation:

Human activities cause many damages to marine mammals in general. One of these activities is fishery. The nests are intercepting the migratory routes of animals or are floating free in the sea after being discarded. They are extremely strong, so whenever animals get stuck on them, they might carry them for months or years, affecting their diving, foraging, feeding, and reproductive behavior. These nets might hurt the animals´ skin, producing a wound that will probably get infected.

A few years ago, at least 50,000 northern fur seals died per year after getting stuck in fishing nets. The populations of these animals decreased sharply, affecting their reproductive and growth rates. In the present, due to the decrease in their population size, the number of dead animals is around 30,000 per year. This reduction in death is only because there are much fewer animals every year.

Which of the following are characteristics of archaeal cell membranes that probably help them survive at very high temperatures?
torisob [31]

Answer:

Option-B, C and E

Explanation:

Archaebacteria are a group of prokaryotes which can survive the extreme conditions. The archaebacteria which can survive very high temperature are called hyperthermophiles. The hyperthermophilic bacteria can survive temperature range between 70 t 125 °C observed in hydrothermal vents.

The archaea bacteria can withstand the high temperature as their membrane is adaptive. The membrane of the archaea is more stable due to the ether linkage which makes carbon less chemically reactive. The phospholipids possess a monolayer which decreases the layer fluidity and thus the unwanted movement of molecules.

The archaea also contain cyclopentane rings in the ester-linked phospholipids which allows tight pacing of the molecules which decrease the movement of solute into and out of the cell.

Thus, the selected options are correct.
