Answer: (TFIID) TBP-> TFIIB IIA--> TFIIF RNA POL II

Explanation:

Remember that in eukaryotic organisms, transcription and processing are coupled processes. There are 3 different types of Rna pol. In the case of RNA pol II transcribes genes that encode proteins (mRNA synthesis). Transcription factors are involved, for example: TFIID, TBPs, TAF (recognizes TATA promoter center, regulatory functions), TFIIA (stabilizes TBP union, antirepressant function), TFIIB (RNA Pol II starting point selection).

Internal threats are always accidental and stem from poor access controls. Only external attackers intentionally plan and carry
Troyanec [42]

Answer: false

Explanation: External threats are not intentional.

Companies face business risks every day, and those risks are part of every organisation which can be in form of

--- External threats (economic, social , political and Micro threats )are threats or risk that cannot be controlled by a company or predicted with a high level of reliability. Therefore, making it difficult to reduce the associated risks.

-And Internal threats are threats that happen inside the organisations which can be predicted with some reliability, and therefore, provide chances of reducing it.

They both can lead to lower revenue, profits, and financial loss.

John and Joshua used a light microscope to observe a plant cell. They indicated the magnification as x1000. Given the eye piece
Zinaida [17]

Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100
