Answer:
Viruses rely on the cells of other organisms to survive and reproduce, because they can't capture or store energy themselves
Marine biologists study changes in the ocean. so they will look at the chemical composition of deep waters and see how consecrated the oxygen is. They will also study the movements of the plates because when planted move it usually makes new food for deep life
they will also check animal concentrations in certain areas.
Another thing they do is track animal movements. this could be by putting a tracker on a whale or a shark or anything and watching its depths it goes or watching the distance it goes in a day.
Answer:
Blowfly adults looking for a place to lay their eggs
Explanation:
Blowfly adults are attracted to the gases and fluids of a dead body and usually lay their eggs on a dead body within the first two days after death.
The eggs then turn into larvae then enter pupal stages and then become adults themselves. Forensic entomologists can determine how long a body has been dead by the stage of development of the blowfly with the ambient temperatures that have been present.
Answer:
Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.
