Explanation

 A cut in the skin with jagged edges that's caused by a forceful tearing of skin tissue is called a laceration.

Lacerations are a type of wound that can be deep and often involve significant bleeding. 

Causes

Lacerations are caused by blunt trauma to the body. 

They can involve the skin, mucous membranes, and deeper body structures. 

Lacerations can be contaminated with bacteria and debris from whatever object caused the cut. 

Explanation

The initial data collected by Emergency Medical Technicians (EMTs) to evaluate a patient's condition is called Assessment.

This assessment includes vital signs, the patient's medical history, and any other relevant information that helps the EMT understand the patient's needs.

It is the first step in providing appropriate medical care and allows the EMT to decide the level of intervention required.

Explanation

An alkyl group is formed by removing a hydrogen atom from an alkane, and since the hydrogen atom is removed with one bonding electron, the resulting group has an unpaired electron, making it a radical. 

Explanation

Fluorine, being the smallest halogen, has the weakest intermolecular forces and therefore the lowest boiling point. 

Explanation

The stop codons are :

1. UAA
2. UAG
3. UGA

A stop codon is a sequence of three nucleotides (a trinucleotide) in DNA or messenger RNA (mRNA)

That signals a halt to protein synthesis in the cell.

There are 64 different trinucleotide codons:

• 61 specify amino acids 
• 3 are stop codons
  

Explanation

Geology is the study of the various processes that occur on and inside the surface of the earth.

Similarly, Entomology is the branch of biology that deals with the study of insects.

Entomology: علم الحشرات، وہ علم جو حشرات کی ساخت سے تعلق رکھتی ہے

Insects: کیڑے مکوڑے یا حشرات 

Explanation

Sunspots are dark areas in the Sun's photosphere, which are cooler than their surroundings

The Sunspots on the Sun's Surface with a periodicity of 11 years.

They consist of a central darker region, known as the umbra,

and a surrounding region, known as the penumbra.

Additional Information:

Bright spots on the surface of the sun are called Plages

Explanation

 Glycolysis is the initial stage of both fermentation and cellular respiration, breaking down glucose into pyruvate and generating a small amount of ATP and NADH, regardless of whether oxygen is present. 

Explanation

The organelle that is not present in animal cells is the Plastid. 

Plastids, including chloroplasts, are organelles specific to plant cells and are not found in animal cells. 

Endoplasmic Reticulum:

Present in both animal and plant cells. 

Ribosome:

Present in all cells, as they are the site of protein synthesis. 

Mitochondria:

Present in most animal cells, responsible for generating energy. 

Explanation

To find the unit vector of A = 8i + 2j + 2k, follow these steps:

1. Find the magnitude of vector A:

   √(8² + 2² + 2²) = √(64 + 4 + 4) = √72

2. Divide each component by the magnitude:

   Unit vector â = (1/√72) × (8i + 2j + 2k)
