With the help of endospores, or thick-walled structures that help the bacteria survive harsh conditions.

What mechanism allows both bacteria and viruses to survive harsh environments e.g in the gut?

I'm guess is that... the bacteria and viruses forma a thick coat, called an endospore inside them that allows them to survive harsh enviorments while making them dormant (resting cells) at the same time. once the envorment becomes suitable again, the endospore deteriorates and thus the bacteria or virus once again becomes prominant ( non- resting, it can move around now). i think soooooooooo

How does bacteria survive?

There are three types of bacteria. Some bacteria are animal-like. The prey on the on other bacteria for food in order to survive. Other bacterias are fungi (mushroom) like. They survive by getting nutrients from dead objects. The fungi -like bacteria is commonly used today s yeast or for curing infections. The third type of bacteria is plant-like. They use photosynthesis to make thei food.

Why do the bacteria used in recombinant DNA expirements have been changed so that they can only survive under special conditions in a laboratory?

Your grammar for this question is not very good however, I believe I can answer your question. If they do get change so they can only survive in a certain condition in a laboratory, I would most likely be to make the bacteria not able to survive Outside the lab. In other words, they don't want it getting out. This would be because they usually give the bacteria a resistance to certain antibacterial solutions so that when they cultivate he bacteria, the bacteria that did not accept the plasmid will die from the antibiotic that got mixed into the Agar. In other words, the only bacteria that would grow are the bacteria have accepted the plasmid.

Can a willow tree survive in harsh climate?

There are several varieties of willow trees and some varieties areable to survive in harsh climates. Types of willow trees that growin the extreme northern climates include the sage leaf and flatleaf.

How do bacteria survive harsh conditions?

They form an endospore. An endospore is a thick cell wall that helps protect them. Endospores enable bacteria to lie dormant for extended periods of time when the environment is unfavorable (such as extreme temperatures, radiation, extreme pH levels, extreme pressures and harmful chemical agents). Then, when the environment becomes more favorable, the endospore can reactivate itself to the vegetative state.

How are cactus' able to live under such harsh conditions?

Cacti have adapted to extremely arid and/or semi-arid hot environments. They show a wide range of features which conserve water. Their stems have adapted to become photosynthetic and succulent, while the leaves have become the spines for which cacti are well known. The bodies of many cacti are thick and have water-retentive tissue Most cacti have a short growing season and long dormancy. They also have the ability to form new roots quickly. Two hours after rain following a relatively long drought, root formation begins in response to the moisture.

How do seals survive the harsh wether i need to know?

Seals are very good at surviving cold temperatures, because they are protected by a thick layer of fat under their skin, called blubber. It is extremely effective- there is no ocean on earth so cold that it doesn't have seals.

How was the harsh condition reaching the Oregon Trail?

Very harsh. Pioneer journals describe crossing flooded rivers and having whole wagons getting washed down river and how they lost everything. They write about the sickness, death, and heat. How, when going over the mountain passes, the wagons would go over a cliff and they would loose family members and all of their stuff. That they would bury their dead along the trail and hope it was deep enough so animals wouldn't dig up the bodies. Of the fear of Indian attacks, of getting lost, of death of a child, of having enough food, weather conditions, and anything else. One woman writes about her husband dying on the trail leaving her with 6 children and a newborn baby. She keeps going, looses her wagon in the mountains pass, and when she and her children finally arrive in Oregon they are in rags, hungry, and on foot. We can't even imagine what these people when through.

How can lichens survive in habitats so seemingly devoid of nutrients and under harsh physical condition?

Lichens are one of the first organisms to colonise a newly disturbed area and are a part of the first stage in plant succession. Like mosses lichens have a number of adaptations which allow them to survive seemingly nutrient free habitats. Lichens, unlike vascular plants can grow with very little nutrients. There are enough nutrients carried in rain water and dust to allow lichens to grow on rock faces etc.

Bacteria that can survive without oxygen are?

If they CAN survive without oxygen, they are called facultative anaerobes . In other words, these can survive with or without oxygen. If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes . In other words, these can only survive if there is no oxygen.

How harsh were the conditions at breitenau concentration camp?

In the eyes of the Nazis, the deaf were of "minor value". The assumption that deafness was a "hereditary disease" lead to forced sterilization. Breitenau was a Nazi education and labor camp established in June 1933 in Germany. It was located in Guxhagen, ca. 15 km south of Kassel and was built around the Breitenau monastery. By the end of 1933, 11,000 people were arrested and placed in concentration camps. Only a few of them were brought to Breitenau. After the Law for the Prevention of Hereditarily Diseased Offspring was made, Breitenau officials began to test prisoners for hereditary diseases. Many of the prisoners who were found to have hereditary diseases were often transported to euthanasia killing centers or kept at Breitenau under penalty of being forcibly sterilized.

By forming this structure some bacteria can survive harsh condition?

They form an endospore. An endospore is a thick cell wall that helps protect them. Endospores enable bacteria to lie dormant for extended periods of time when the environment is unfavorable (such as extreme temperatures, radiation, extreme pH levels, extreme pressures and harmful chemical agents). Then, when the environment becomes more favorable, the endospore can reactivate itself to the vegetative state.

Do Koala bears have harsh living conditions?

Koalas, which are not bears at all, do not necessarily have harsh living conditions, althoug it is true that they sometimes endure terrible heatwaves in southern Australia, which often lead to devastating bushfires. It lives mostly within the temperate zones. Its habitat is eucalypt woodland and bushland , but of the several hundred species of eucalyptus ("gum trees"), koalas prefer about 60 varieties, with their specific preferences being limited to a couple of dozen. After that, there are still just one or two key species that a koala population must have to thrive, even if the number of trees of that species is only small. Koalas live in cool temperate zones, right up to hot, sub-tropical zones. They live in eucalyptus trees and are mostly nocturnal and eat certain types of eucalypt leaves exclusively. They are particular to Eastern Australia. Koalas live in a range of habitats, as long as there are abundant eucalyptus trees of the sort they prefer. They are found on coastal islands, tall eucalypt forests, bushland and low woodlands inland. Koalas spend most of their time nestled in the branches of their favoured trees. They do not shelter in tree hollows or nests, but sit comfortably wedged in between tree branches. Koalas are not found in rainforests, nor in grasslands or deserts. These biomes do not support the eucalyptus trees which koalas favour. They are also not found in Alpine or snowy regions.

How have the Adelie Penguins adapted the the harsh conditions in Antarctica?

"Adelie Penguins, like the other three penguin types that breed onAntarctica's beaches, increase their body warmth by basking in the(usually) 24-hour sun, or by retreating to liquid water, which isalways warmer than the ambient Antarctic air. The home of all penguins is sea water, and that's where their foodchain can be found. All penguins regulate their body heat throughthe layer of fat between their skin and their vital organs. Thiskeeps them warm wherever they are. No animal lives on Antarctica: it's too cold and there is on foodchain on land its land.

How did the Jews deal with such harsh conditions?

The upper middle and higher class fled to another country. Everyone below found a hiding spot or were sent to concentration camps __ Not all upper and middle class fled. Many were rounded up and sent to concentration camps as well. Those that did manage to flee, usually went to other European countries. As the Nazis moved in, they ran out of places to go. Many countries simply refused to allow them to migrate to their countries so they too were rounded up and sent to camps as well.

Why does not bacteria survive in harsh conditions?

There are a number of bacteria that DO survive in harsh environments be it pH or temperature extremes or an environment that is very salty. Bacteria that don't survive in harsh conditions usually lose cell wall integrity and break apart, or lose all their intercellular fluid and shrivel up.

How do animals survive in the harsh desert climates?

There is no one way desert animals survive. Instead, there are a lot of ways animals (and plants) survive in deserts, in part because there are different kinds of deserts. Some are hot, some are cold, some get a lot of rain occasionally, while others get no rain ever, but do get a lot of dew frequently. The same survival techniques do not work everywhere.

How did Anasazi survive in such harsh environment?

The Anasazi irrigated their very arid landscape to grow corn, beans, and squash, herded sheep, hunted rabbits and deer and bison, and tried to live in harmony with the elements; which included the Great Spirit and other, lesser gods.

How do spiders survive you harsh winters?

Spiders like the garden orb weavers, argiopes, widow varieties thatonly live one season, will die in Winter, leaving behind their eggsac for the next season. Other spiders like tarantulas and fishingspiders, that live longer may hibernate in Winter spending the coldweather under tree bark or rocks, or in cellars and attics. Someadults survive by preparing a winter nest of silken webbing underloose bark within which they are insulated from the cold. Inseveral species, young spiderlings hatch out, then remain in acommunal webbed egg sac through the winter. Those spiders thathibernate in leaf litter and in rock piles often are not deeplyasleep, and on mild winter days may crawl about in search of insectfood that is plentiful and easy to secure in its dormant state.Young spiders often take refuge in moss, and should you bring aclump into the house, be prepared to have spiderlings and manyother little hibernating creatures crawl out as warmth unlockstheir muscles and increases their metabolism and consumption ofoxygen.

How do penguins survive in its harsh environment?

Penguins survive their harsh environment because of a layer of fatand water-resistant feather patterns that are tightly packed. Thefeathers keep out the brutal Antarctic winds. When possible, and apenguin wants to 'warm up', the animal simply dives into the warmerwater, which is always warmer than the ambient air above the waterline.
