Doppler's effect can be defined as the increase or decrease in the frequency of the waves, such as the sound waves and light waves when the source moves closer or farther away from the source.

In forensic investigation of a crime involving a shooting, the Doppler effect is useful in determining how far the shooter was. By determining the distance from which the shot was fired, it can be concluded whether the crime was a suicide or homicide or in self-defense.

In order to transport the weapon used in the crime to the lab by carefully packaging it in a paper bag. The trace evidence, such as hair, or blood, that may be present on the weapon must be packaged separately. The packaging should be labeled and then transported to the lab. It should be made sure whether the cartilage is empty or not. The safety of the weapon should be on while delivering it to the lab for analysis.

 The Doppler Effect is when sound waves become stretched behind a moving object. This is applicable in ambulances in which frequencies matter with distance from the person hearing. This is useful for a forensic investigation involving a shooting because witnesses can Identify a firearm by the sound it makes.

Explain how seasonal changes in carrying capacity can account for the annual cycles in population size observed for this populat
murzikaleks [220]
<span>Carrying capacity is how many animals a given location can hold. This means that if the number of rabbits, n, exceeds the carrying capacity, C, then the difference between the number of rabbits minus the carrying capacity (n - C) will likely die to starvation. Seasons in Ohio can directly affect carrying capacity because colder weather usually means less food. Rabbits can eat plants as well, and in winter, plants do not do well to survive. Thus, the carrying capacity will decrease. In contrast, in summer, plants flourish so the carrying capacity will increase.</span>

Discuss some of the possible side effects that occur when the pyramid becomes blocked.
faltersainse [42]

The imbalance in energy would cause warming up of the planet and variety in fauna would be limited.

Explanation:

in an energy pyramid large amount of the energy gets dissipated only 10% of the energy is transferred to other level. Trophic level tells the placement of organism in a energy pyramid.

If at any time the pyramid gets blocked:

The passing of biomass and energy gets break to each level.

The organism at the higher level will be scarce of resources as nutrition and energy for growth, multiplication and metabolism.

The organisms at the higher level will get die eventually and vanish from the earth as no reproduction.

The energy dissipated will be in large amount disturbing the ecological chain.

The imbalance in energy would cause warming up of the planet and variety in fauna would be limited.
