Explanation:
Protect the crime scene.
This means that the first responder should protect the public and the crime scene and also control the changes made to the crime scene to the best of their ability.
Protection of the public means the evacuation of the public from the crime scene to a safer area.
The crime scene should be protected against evidence distortion.
The control of changes made to the crime scene maintains the original evidence present at the crime scene.

Answer:
Fire arm safety measures shall be taken
The gun should not be transported by placing a pencil in the barrel or inside the trigger guard.
There shall be documentation of the location of the gun.
Photos of the location of the gun should be taken.
There after the gun shall be retrieved from the river safely.
Since the gun shall be wet at the time of collection, it shall be kept in a plastic bag.
The gun shall then be transported to the evidence receiving area.
The gun should not be held in the plastic bag for more than two hours since this could lead to the growth of microorganisms which can destroy evidence.
3
Answer:
Things to keep in mind
Fire arm safety mechanisms should be put in place.
Evidence packed in plastic material should not be held in the packing material for more than two hours.
Only large quantities of dry powder should be collected and stored in plastic bags.
Any items which may cross contaminate each other must be packaged separately to avoid evidence contamination
The containers should be closed and secured to avoid the mixture of evidence during the transportation process.
Each container should have:
The collecting person's initials
Date and time it was collected
Complete description of the evidence and where it was found
The investigating agency's name and their file number.

Answer
Bullets from near the body of the victim should:
Be packaged separately and placed in paper envelopes or small cardboard pillboxes.
Handled carefully to prevent alter of evidence such as fingerprints.
The bullets have to be submitted to the crime lab for identification of any evidence present on them that could help in investigation.
Be kept safe and separate from the gun.
The container should be labeled to warn that the contents are precautions should be taken to prevent anyone from being injured.
5
Answer:
The gun and bullet might help us out in finding out:
The fingerprints of the user: The gun can be checked to retrieve the fingerprints of its handler if any.
The bullet cartilages shall reveal the owner of the bullets, this shall lead to the identification of a suspect.
Blood, hair that might be found on the gun and bullets might help in DNA analysis. This shall in turn lead us to a suspect.
The guns registration number shall lead us to the owner of the gun used thereby the suspect in the crime.

Answer:
The officer who arrested Oscar Pistorius on the night Reeva Steenkamp was killed last year testified Friday that police at the crime scene mishandled evidence, including a ballistics expert who handled the murder weapon without gloves.
This in turn led to confusion in evidence of the case.
The police should have instead used gloves in handling the pistol at the crime scene.
This would have prevented the intoxication of evidence.

Can genetic engineering cause harm to humans?
Answer:
There are many risks involved in genetic engineering. The release of genetically altered organisms in the environment can increase human suffering, decrease animal welfare, and lead to ecological disasters. The containment of biotechnological material in laboratories and industrial plants contributes to the risk of accidental release, especially if the handling and storage are inadequate.

Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.

How does the Sun heat the Earth?
Explain your answer in your own words.
Explanation:
The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.

How does natural selection lead to changes in organisms?
Answer:
it is every organisms goal to "survive and repopulate" therefore, with natural selection the weaker organisms die because they did not possess the traits necessary to survive, and the strong survive and repopulate

Why is genetic variation among individuals beneficial?(1 point)
A) More genetic variation means higher rate of survival versus species that have less genetic variation.
B) Genetic variation staves off extinction because it creates a fit population.
C) Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
D) Genetic variation leads to more new traits in the population which means evolution can occur faster.
Answer:
Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
Explanation:
it was the correct answer from the test
Genetic variations may lead to the diversity in the phenotypes of surviving individuals. It reduces the chances of extinction.
What do you mean by Genetic variations?Genetic variations may be defined as the presence of differences in sequences of genes between individual organisms of a species.
Genetic variation among individuals is beneficial because some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
Therefore, it is discussed above that genetic variation among individuals is beneficial.

Mr. Yien reports to the clinic after having passed reddish- colored urine this morning. He reports that he has been feeling very fatigued for several weeks and hasn't been urinating as much as usual. He also tells you that three years ago he had a kidney transplant. You order a urinalysis, which is positive for large amounts of blood and protein. What is potentially causing Mr. Yien's problems, given his medical history? Explain.
Answer:
Kidneys typically don't permit giant proteins to go through them. however thanks to harm to the units of excretory organ (nephrons), these proteins go through kidneys and ar suffered excretory product. This sickness is named symptom.

What items are used to identify the genetic makeup of an unknown organism?
Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.
As mentioned in the video, Dr. Nachman and his colleagues have collected dark and light colored mice from dark and light colored rocks in other areas of the American Southwest and found similar patterns (i.e., dark colored mice were more likely to be found on dark rocks; light colored mice were more likely to be found on light rocks). However, genetic analysis showed that the dark fur color in other rock pocket mouse populations was caused by mutations in different genes. This means that there is more than one way (genetically speaking) to make a mouse dark. It also means that adaptive mouse coloration has occurred more than once in similar environments across the southwestern US. How does this information support the concept that natural selection is not a random process
Complete question:
In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.
How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. They can do it by having a similar fur color that the color of the rocks they live on. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

Answer:
it may affect the animals and other tree's.
Explanation:
it may affect animals because since it is a new tree, you might not know that it may be harmful for some animals, like maybe the berries the produce are poisonous or fruits some animals are forbidden to eat. this may be a problem because some animals may accidentally eat that fruit and possibly be injured or die.
trees need sunlight and food, if another tree hopes in suddenly there would be more competition for sunlight and water, there may also be not enough water and sunlight for all the trees to share. this is a problem because if the trees can't get enough sunlight and water, they would die and this leads to a broken home for the animals living in that tree.
