Single-celled organisms would likely fare well.
The television show 'Mythbusters' tested and seems to have proved that cockroaches would not survive radiation very well at all. In fact they discovered that flour beetles could and did survive doses of 100,000 Rads (1000 Rads is lethal to a human) with no signs of dying out.
Many, not just 3. Insects and bacteria are two. Creatures that live underground will also survive more often than those that live on the surface.
Depending on the situation, it'll most likely be either military installations/supplies or the most populous cities. Possibly both.
Runaway volcanism (not likely).Massive object impact (not likely).The sun swelling to a red giant (most likely).Earth going outside the green zone and too close to the Sun (very likely)."God" or a deity (not likely).Nuclear war would not be likely to cause destruction by fire; there is a miniscule chance of setting the atmosphere alight, but nuclear winter (extreme cooling caused by fallout) is more likely in the event of absolute nuclear war.
Not likely since they wouldn't survive the winters in Europe...where most moats were built.
It depends on how large of a nuclear war. If India should have a nuclear war with China or Pakistan, the human race would probably survive it. However, if the US had exchanged nukes with the USSR during the Cold War, there might have been no safe place in the world from the radioactive fallout.
From 1945 until the late 1970s or early 1980s the United States always had the most nuclear weapons. After then the USSR/Russia has had the most nuclear weapons.
The mostly likely to survive even nuclear war are rats.
an organism that needs lots of water to survive is able to prevent water from evaporating
When an organism is petrified its organic tissue is most likely replaced with minerals.
Hydrogen is the element that is most likely to undergo nuclear fusion.
cells
may be is the living organism
most likely the organism will die
An organism that has a hard structure is most likely to become a fossil because it can survive through different weather changes and an organism with a soft structure will most likely dissolve or decompose.
bacteria
Actually a very complex question. Most insects and bacteria would likely survive, but it depends on the exact weapon effect(s) you are concerned about.
if an organism can only be seen though a microscope , what is most likely true of that organism
Natural Selection a theory originated by Charles Darwin states that the fittest will survive. The organisms most likely to survive are the fittest, the ones that can adapt themselves to a changing environment. Edit: it's those with traits best suited to their environment. -Holy122
