Please Help. Compare the energy input and output for nuclear fission and nuclear fusion.
Andrew [12]

Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. Comparison chart Embed this chart Nuclear Fission, Nuclear Fission is the splitting of a large atom into two or more smaller ones. Fusion is the fusing of two or more lighter atoms into a larger one. Natural occurrence of the process: Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun. Byproducts of the reaction: Fission produces many highly radioactive particles. Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that. Conditions: Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is

Which type of solution will cause cells to swell, or even to burst?
Inga [223]

Answer:

(b) Hypotonic solution

Explanation:

  • Any solution having lower osmotic pressure as compared to another solution is called as a hypotonic solution and the reason that a solution is hypotonic is that it has more water and lesser dissolved solute in it.
  • If a cell is placed in a hypotonic solution, the amount of water content in the cell would be lesser as compared to that of the solution and hence, the water will enter the cell due to which the cell will swell and may even burst.
  • The water molecules can enter the cell through the semipermeable membrane and in case of plant cells, the presence of cell wall may prevent it bursting, however, the animal cells lack the cell wall and hence if kept in hypotonic solution for long these cells may burst.

Certain flightless beetles have wings that have no function. The wings are an example of which type of structure?
iVinArrow [24]

<span>The wings on the beetles are examples of vestigiality. Vestigiality is a structure with attributes that have apparently loss its ancestral function but stil present during evolution. It is a normal evolutionary process in the changing environment that does not pressure them to evolve.</span>

An organism has brown fur, eats nuts and berries, and hibernates in the winter. What biome is this organism likely a part of? Ex
hammer [34]

Answer:

Forest.

Explanation:

Berries and nuts are typically fruits and products of trees, and there must be plentiful amount in which to have a population (though it states only an organism, but it can be assumed). Brown fur is typically <em>camo</em> against a brownish background, which can be reflected essentially through bark & wood of trees.

*Most likely the given organism is a squirrel, which typically prefer forest or habitats with trees or tree-like objects.
