Is hair a good source of criminal evidence, explain your answer?
Answer:
yes
Explanation:
Hair contains DNA of the criminal. DNA is unqiue to everyone, no one is ever simialr in DNA to eachother. So if a hair sample is found, then testing it would provide a great piece of evidence.
Answer:
yes because if the body is unditfied they can always take a hair sample and run it but if it is the killers they run it to see if it has dna strands and then if they find something they will get the suspect in and take a piece of their hair to see if it is the perfect match

How did a famous event change the course of the American Revolutionary War? in essay form pls
Answer:
The American Revolution was a political battle that took place between 1765 and 1783 during which colonists in the Thirteen American Colonies rejected the British monarchy and aristocracy, overthrew the authority of Great Britain, and founded the United States of America. See the fact file below for more information and American Revolution facts.
-The American Revolution, also known as the Revolutionary War, began in 1775.
-British soldiers and American patriots started the war with battles at Lexington and Concord, Massachusetts.Colonists in America wanted independence from England.
-The British government attempted to pass some laws, enforce several taxes, and increase more control over the colonies.
-The colonies strongly objected to these laws and taxes.
-They wanted England to have no control over them.
-For ten years before the war actually started, there was a lot of tension between England and the colonies.
-The colonies had no central government at the beginning of the war, so delegates from all the colonies were sent to form the first Continental Congress.
-George Washington, a former military officer and wealthy Virginian, was appointed Commander in Chief of the Continental Army.
-Members of the Continental Congress wrote a letter to King George of England outlining their complaints and declaring their independence from England.
-On July 4, 1776, the Continental Congress adopted the Declaration of Independence, in which the colonies declared their independence from England.
-The war ended in 1783, and the United States of America was born.

Explanation:
(By CMI W Sunce Source
1. What organism is pictured?
2. Name and describe the process is shown on the right.
3. What is the name of the circular bodies? What happens there?
Answer:
Explanation:
Suppose an explorer discovered a unique new species of plant and collected a sample for analysis by a geneticist. The geneticist then isolated chromatin from the plant sample and examined the chromatin using electron microscopy. The chromatin observed was organized in a way that is similar to beads on a string A small amount of nuclease was then added, which was observed to cleave the string into individual beads that each contained 280 bp of DNA.
Histone H1 H2A H2B H3 H4 H7 (new histone)
Percentage 12.5% 25% 25% 0% 26%
After thorough digestion with more nuclease, only a 120 bp fragment of DNA remained attached to a core of histone eins. Analysis of the histone core revealed the data dicated in the table to the right.
Using the data provided, determine the conclusions that the geneticist could make about the likely structure of the nucleosome in the chromatin of this new plant species
A. The nucleosome core contains a heterodimer of the histones H7 and H1
B. The nucleosome core contains two each of histones H2A, H2B, and H4
C. The nucleosome core contains a homodimer of the histones H2A, H2B, and H4
D. The nucleosome core contains one each of histones H1 and H7
E. The nucleosome core histone H7 replaces the standard histone H3

noah created a model of a glacier to help explain how glaciers change the surface of Earth. He froze two large blocks of ice. One block was pure water. The pther was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Noah's model explain how glaciers change Earths surface?
Answer: The model is depicting the glacier erosion.
Explanation:
The glaciers are responsible for causing erosion of the earth. They transport the materials away from the locations were they are earlier situated. They carve the materials present beneath the land. They erode the materials like soil, pebbles, boulders, against the pressure of the unstable mass of the ice moving down the slope. The broken ice mass carriers away the broken rocks, materials and soil debris far away from the places where they have been originally situated. This causes the glacial erosion. Also the broken and displaced rocks displace the soil and other materials come in contact with during erosion.
According to the given situation, the ice formed with water only had no impact on the tinfoil on the other hand the ice containing the sand and rocks removed the tinfoil from places. This is because of the friction created by the sand and rocks on the tinfoil. The glacier material like ice, soil, rocks due to friction erode the material come in contact with it with an appreciable pressure underneath.

Which of the following is not correct about diffraction?
Answer:
Diffraction occurs just with electromagnetic waves.
Explanation:
The information that should not be true about diffraction is that it arise with the electromagnetic waves only.
What is diffraction?It is considered as the process where the beam of light or the other system waves should be spread out that leads of passing via the narrow aperture or it should be an across of an edge that should be accompanied by interfering between the formation of the waves that should be generated.
So the above information should be considered.

Which describes a similarity between abiotic and biotic factors?
Answer: They are both necessary for organisms to survive.
Explanation:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
