Answer:

false

Explanation:

Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.

RIBOSOMES on the ROUGH ENDOPLASMIC RETICULUM

Explanation:

This is the site of protein synthesis usually find attached to the rough endoplasmic reticulum or freely on the cystosol,

When they are attached to the endoplasmic reticulum they appeared as back dots which makes the surface of ER to appear rough, hence the name ROUGH ER. Smooth ER, lacks Ribosomes, and therefore appears smooth,

Ribosomes are made up of PROTEIN AND RNA.

They are 25nm in diameter;when viewed under high magnification, where theymade up of two sub-units the small and large units.

The protein synthesize by the Ribosomes are passed into the sacs of Rough E.R for transportation,

Basically, a complete Ribosomes is refereed to as 70S for prokaryotic ribosomes and 80S for Eukaryotic Ribisomes.This refers to their sedimentation Co-efficient in Svedberg units,the Eukaryotes sediment faster than the Prokaroytes

Answer:

By decoding information with the help of transfer RNA (tRNA).

Explanation:

The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.

Answer:

Explanation:

The Electrically initiated Improvised Explosive Device (IED) generally consist of four component with the acronym PIES, the P stands for power sources which supplies electrical charge to the I; initiator contains a small amount of explosives such TNT or PETN which triggers the remaining amount of explosive, E is the explosive itself which is triggered into explosion by the initiator and finally the S, Swtich, example clock or a cell phone which determine the device explodes
