Scientists.

They utilize and make use of the scientific method in order to have clear basis and evidence for their investigations. Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation
2. Hypothesis
3. Experimentation
4. Interpretation of data
5. Evaluating the data
6. Passing and recording the data

These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.

the only reason i am wasting one of the two answers your post is allowed to get is because its been 3 hours and no one has answered yet.

Where do you go to school? I think it is very coincidental that you have the exact same question i do, and you had the question exactly when I got the question...about 3 hours ago. Now it IS a curriculum so its not that weird, but by any chance are you in K12? 8th grade?

Dvinal [7]

Answer:

All of these environmental disturbances use such energy present within the ecosystem to survive and reproduce. In order to conserve the health of the environment, the best thing that can be done is finding ways to reuse the energy as much as we can such as recycling cardboards or tin cans. Other ways would be to lower use of carbon emitting cars and have more conservation awareness.

The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man

IgorLugansk [536]

Answer:

Number of nucleosomes in $2.9 * 10^9$ bp is equal to $1.47 * 10^7$

Explanation:

For wounding one nucleosome, total length of DNA required is equal to $146$ bp

The length of linker DNA in mammals is equal to $50$ bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

$= 146 + 50\\= 196$ bp

Thus, in $196$ bp length of DNA, the total number of nucleosomes is equal to $1$

Thus, number of nucleosomes in $2.9 * 10^9$ bp is equal to

$\frac{2.9* 10^9}{196} \\1.47 * 10^7$

What happens to RNA polymerase II after it has completed transcription of a gene? a. It begins transcribing the next gene on the

Over [174]

The correct answer is: b. It is free to bind to another promoter and begin transcription

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex.

RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
