One important adaptation that separated us from other animals in our evolutionary trajectory is _________.
malfutka [58]

We can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

<h3>What is bipedalism?</h3>

Bipedalism was the adaptation of early human ancestors to abandon movement on all fours and begin to walk up-right. This was a vastly important adaptation as it provided the early humans with freed hands, allowing for many other uses such as tools and social cues.

Therefore, we can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred

ohaa [14]

Answer:

C. transcribed, mRNA

Explanation:

DNA, also known as deoxyribonucleic acid, is a molecule that holds genetic information needed to make other molecules in living organisms. However, before this genetic information can be harnessed, it needs to be expressed via two processes called transcription and translation.

Transcription is the first of the two processes that take place during genetic expression. It involves the synthesis of mRNA molecule from a DNA template. In other words, the DNA must first be TRANSCRIBED into mRNA.

Explain the difference between fire resistance and flame spread. describe the hazards firefighters should be aware of during the
Kaylis [27]

Fire resistance is where the amount of time that material has withstood a standard fire exposure whereas flame spread is the speed at which a flame spread along the surface of a specific material and is considered as the difference between fire resistance and flame spread.

Fire resistance is the resistance to fire that is for a particular specified time and is under circumstances of standard heat intensity. It will not structurally fail or else allow the transition of heat and also not permit the side away from the fire so as to become hotter than a temperature that is specified well.

Flame spread is described as the surface burning characteristics enhanced by building materials. It is the most tested property of the fire performance of a material.

Firefighters should be aware of the growth and spread of a fire as they face respiratory hazards in emergency situations which include oxygen deficiency,  temperature elevation, smoke as well as toxic atmospheres. This can also affect both the physical and mental effects of the firefighter and would be worse if proper respirator precautions are not followed.

This indicates that firefighters are regularly exposed to certain concentrations of hazardous materials that include carcinogenic products such as carbon monoxide, benzene, sulphur dioxide, hydrogen cyanide, aldehydes as well as particulates.
