Answer:
Answer is option A (True).
Explanation:
The fingerprint pattern of an individual is unique as no two individuals have the same pattern and it remains unchanged. So fingerprints are considered as one of the main types of physical evidence that can be recovered from a crime scene for identification purposes.
The three types of fingerprint impressions are;
Patent fingerprints or visible fingerprints - They are visible prints that are left on a smooth surface of another object when foreign substances such as blood, ink, or some other liquid present on the skin of a finger come in contact with the surface. These prints are easily identifiable and are visible with the naked eye without any technological enhancements.
Plastic prints - They are visible, three-dimensional prints that are left on soft surfaces such as freshly painted surfaces or materials like wax, gum, clay, soap, etc when a finger comes in contact with that surface resulting in an indentation. These prints are easily observable and no enhancement is required.
Latent prints - They are invisible fingerprint impressions that are left on a surface as a result of the perspiration, moisture or oil found in the ridges of fingers. Since they are not visible to the naked eye, enhancement is required upon their collection.

The best answer is b. 4
The human heart has four chambers - two atria and two ventricles.
1. Right atrium - receives oxygen-poor blood from the body and pumps it to the right ventricle.
2. Right ventricle - pumps oxygen-poor blood to the heart.
3. Left atrium - receive oxygen - rich blood from the lungs.
4. Left ventricle - pumps oxygen rich blood to the body.
The heart is a muscular organ. It is about the size of a closed fist. It is located in the thoracic cavity. It is protected by the rib cage and is the major organ of the circulatory system.
