Answer:
168 J
Explanation:
Work can be calculated using the following formula.
w=f*d
where w is work, f is force, and d is distance.
Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.
f=84 N
d=2 m
Substitute these variables into the formula.
w=84 N* 2 m
Multiply
w=168 N-m
A N-m is the same as a Joule, or J.
w= 168 Joules
Anna does 168 Joules of work.
As the name says the goal of the descriptive investigation is to describe.
This type of investigation has no hypothesis, but only a question. With this type of investigation Tyler will be able to observe all types of insects and study the insects in many various aspects and provides a bigger overview, because it uses both quantitative<span> and qualitative data.</span>
It seems that you have missed the necessary options for us to choose from, anyway, I had to look for it and here is the answer. The one who uses the information provided by cytotechnologists are the pathologists. Hope this answers your question.
The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.
More differences between prokaryotic and eukaryotic transcription:
• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,
• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).
• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.
• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.
