Cell membrane i think as I remember
Hydrogen bonds connecting base pairs must be broken.
The decay of uranium isotopes is used to provide information about the age of Earth.
<h3>
Explanation:</h3>
Isotopes of Uranium U-232, U-233 , U-234 , U-235 , U-236 , U-238 are used as fuel in nuclear reactors or as explosives for nuclear weapons. Uranium 238 is not very radioactive and it constitutes for nearly 99.3% of natural uranium on Earth and has the longest lifetime: its period is 4.5 billion years, about the age of Earth.
Use of radiometric dating techniques help in defining the age of substances (natural or man-made) using the known decay rates of radioactive elements. Each element has an individual decay rate and half life time.
Two Uranium isotopes (U-238 and U-235) are used for radiometric dating. Both the isotopes have different decay rates and half life period. Both are unstable and radioactive. Since two different isotopes produce two different decay clocks (one as a reference to other), it is beneficial in accurately determining the age of samples. The age of earth (rocks or other natural elements) can be easily determined using Uranium isotopes.
The cells would cease to function <span>after a relatively short amount of time (a few years at best, depending on the amount of cells that part normally has). A living being's body parts would also never grow. They would stay the same size since they were born. The only good result is that without mitosis, cancer wouldn't occur.</span>
Answer:
In all different levels of the food webs and food chains, it is seen that damaged members of the prey have become easy food for the predators.
Explanation:
Preys can identify the other members of their species are injured or wounded or fed by the predators by their body fluid in as if a predator eats the prey the blood or other body fluid releases. These fluids or blood help individual prey species to be aware of the predator as they recognize that their species member is wounded or consumed by there olfactory receptors.
There are several other chemicals cue that is species specif that are released by the prey to alarm the other species member by injured or dead members.
Thus, the correct answer is - In all different levels of the food webs and food chains it is seen that damaged members of the prey have become easy food for the predators.
