Forensic scientists have various tasks and responsibilities related to the examination and analysis of physical evidence in criminal investigations and legal proceedings. Three primary tasks or responsibilities of a forensic scientist include Evidence Collection and Preservation,  Laboratory Analysis and Expert Testimony.

1. Evidence Collection and Preservation: Forensic scientists are responsible for collecting, documenting, and preserving physical evidence found at crime scenes. This includes gathering items such as DNA samples, fingerprints, bloodstains, clothing, weapons, and other relevant materials.

2. Laboratory Analysis: After evidence is collected, forensic scientists analyze it in a laboratory setting using specialized techniques and equipment. Depending on the nature of the case, forensic scientists may conduct various types of analyses, such as DNA profiling, fingerprint analysis, ballistics testing, toxicology screening, trace evidence examination (e.g., fibers, hair, soil), and handwriting analysis.

3. Expert Testimony: Forensic scientists are often called upon to testify as expert witnesses in court proceedings. They present their findings, interpretations, and conclusions based on their analyses of the evidence. Expert testimony helps to clarify complex scientific matters for the judge and jury, assisting them in understanding the significance of the evidence in the context of the case.

Answer: C. The carbon cycle

Explanation:

The burning of the fossil fuel like coal will liberate carbon dioxide and carbon monoxide gases into the atmosphere. The carbon present in this gases circulates among the biosphere, hydrosphere, lithosphere and geosphere. Hence, burning of the fossil will affect the carbon cycle.

Answer:

So that they can be absorbed by the body.

Explanation:

Carbohydrates are complex and sugars are simple form of carbohydrates. Since carbohydrates is complex and not easily absorbed it is converted to sugars which the body can absorbed easily during digestion and it is converted to energy to drive the cells. Examples of sugars are sucrose,glucose.

Final answer:

Converting carbohydrates into sugars is essential as it provides energy to the body. During this conversion, glucose is produced, which is the body's main fuel. This process makes carbohydrates easier to digest and allows the sugars to be absorbed by the body.

Explanation:

Carbohydrates are essential macromolecules that originated from photosynthesizing organisms such as plants. These organisms use sunlight to convert carbon dioxide (CO₂) into sugar molecules like glucose (C6H12O6). This process of creating a larger, energy-storing molecule requires energy investment, as represented in the equation 6CO2 + 6H₂O + energy -> C6H12O6 + 6O2.

After consumption, the carbohydrates in our food are broken down into simple sugars via a process known as digestion. The digestion of carbohydrates begins in the mouth with the action of salivary amylase on starches and ends with monosaccharides being absorbed across the epithelium of the small intestine. The monosaccharides are then transported to the tissues, initiating the process of cellular respiration.

During cellular respiration, glucose is oxidized, releasing the energy stored in its bonds to produce ATP (Adenosine Triphosphate), which is the body's main fuel. This is why it's essential to convert carbohydrates into sugars. When consumed, carbohydrates provide much needed energy to the body, predominantly through glucose, a simple sugar. Converting complex carbohydrates into simple sugars allows for easier digestion and absorption by the body.

The statement that describes the order blood flows through the body and the heart is:

• Right atrium, right ventricle, lungs, left atrium, left ventricle, body.

What is blood?

It is a red liquid with different shades that varies according to the amount of oxygen it has inside, that is, hemoglobin.

Characteristics of blood circulation

• It is a necessary substance for oxygenation to occur between cells, as well as to regulate blood pressure.

• Each side of the heart is divided into an upper chamber called the atrium and a larger, lower chamber called the ventricle.

• The blood flows since it has left the right ventricle, has been oxygenated by the lungs and has returned to the left atrium through the pulmonary veins, it is carried to the left ventricle.

Therefore, we can conclude that the main function of the blood is to ensure that oxygen and nutrients are distributed between the cells of each organism.

Answer:

answer is D

l

Explanation:

Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
