Because they have mutated to be able to infect hosts that can be used for the energy and materials needed for the virus to be reproduced. They are constantly mutating, and that allows them to adjust to any changes in environment or hosts so that they can survive.
Some viruses can survive passage through the gastrointestinal tract due to their ability to resist stomach acid and bile salts. However, many viruses are not able to survive this harsh environment and are inactivated before they can infect cells in the intestines.
Thermophiles, which are organisms that thrive in extreme heat, and acidophiles, which are organisms that thrive in acidic environments, are known to adapt and thrive in such conditions. These extremophiles have unique adaptations that allow them to survive and even thrive in environments that would be inhospitable to most other life forms.
It is called a response. Organisms react to their surroundings in order to survive and thrive in their environment.
Examples of extremophiles include thermophiles that thrive at high temperatures, psychrophiles that survive in extremely cold environments, acidophiles that can tolerate acidic conditions, alkaliphiles that thrive in alkaline environments, and halophiles that live in highly saline habitats.
It would not be advantageous for a virus to kill its host because if the host dies, the virus would also die since it needs the host to replicate and spread. It is more beneficial for a virus to keep the host alive so it can continue to infect other individuals.
any virus needs a source of energyl to thrive and dies withing munits in abscense of such source. dirty hands-to-food, sharing the flatware is enough.
Not just survive, but thrive.
One animal that adapts to its environment in order to survive and thrive is the chameleon.
Yes, moss does need sunlight to survive and thrive. Sunlight is essential for moss to photosynthesize and grow. Without sunlight, moss may struggle to survive and may not thrive as well.
HIV virus can not survive in hot water.
Survive, effort, toil.

The word 'alive' rhymes with 'survive' and is a simple word.
Sunflowers are typically annual plants that do not survive the winter. They thrive in warm temperatures and are not well-suited for colder climates.
Yes, moss does need light to survive and thrive. Light is essential for moss to carry out photosynthesis, a process that allows it to produce food and grow. Without sufficient light, moss may struggle to survive and may not thrive as well as it would with adequate light.
