Explanation:
1. the similarity between biosphere and ecosystem is that they both have organisms that depend on each other and the difference is that biosphere uses every single organism while ecosystem only uses organisms that are inside of the ecosystem. 2. the similarity between theory and hypotheses is that they are both something that have to be scientifically proven and the difference is a theory relies on evidence and a hypothesis relies on a possibility. 3. a similarity between independent variable and constant is that they both change at the same time and the difference is that an independent variable is controlled or changed by the scientist while a controlled variable is one that they want to remain the same.
Answer:
Left amount of Polonium-210 after 115 days will be 4.5927 microgram
Explanation:
We have given initial mass of Polonium-210 
Decay rate x= 0.502% = 0.00502
Time t = 115 days
We have to find the left amount of Polonium -210 after 115 days
We know that left amount is given by
So left amount of Polonium-210 after 115 days will be 4.5927 microgram
This is a typical example of R selection life strategy. These species, including the Atlantic cod, produce a large number of offspring with a low chance of surviving to adulthood. This strategy is particularly successful in environments that are unstable. The main advantage of this strategy in changing environments is that the ''cost'' of making offspring is very low, so you the species can produce large numbers offspring, ensuring that at least some of them will survive into adulthood and continue the species.
Natural selection, in this case, favors the individuals that are able to adapt the fastest to the changing conditions.
Humans can will themselves to eat more, as we know that food comes easy to us.
Animals, on the other hand, top priority is survival, so they usually wouldn't think about eating more because it just "tastes good."
