Answer:

Scientific Method.

Explanation:

A scientific method is basically a method or a process when you conduct an experiment. Normally, the process goes like this:

1. You make like a question or something that you want to investigate, it's like the aim of the experiment.

2. You make an experiment and a hypothesis. A hypothesis is basically a guess on how the results of the experiment would turn out. You don't have to be correct for the hypothesis since there is no right or wrong answer.

3. Conduct the experiment. I don't think this needs a detailed explanation since experiments vary from one another.

4. Collect results. The data you collect come in different ways based on your experiment, but it is crucial you get data so that you can answer your question in 1.

5. Make inferences. You can't directly get a conclusion or answer from the results, so inferences are needed.

6. Craft a conclusion or answer. This is the final step when conducting an experiment and the part where you have the answer you needed when you conducted the experiment :)

What is the total number of elements in group 17 that are gases at room temperature and standard pressure?
White raven [17]

Answer:

Only to elements are gases at room temperature and standard pressure.

Fluorine and chlorine.

Explanation:

The group 17 is called halogen.

There are five elements in halogen group.

All halogens required one electrons to complete the octet and to get the noble gas electronic configuration.

All halogen elements have seven valance electrons.

Halogen elements:

Fluorine, chlorine, Bromine, iodine and astatine

Fluorine is gas at room temperature which s 25°C and standard pressure which is 1 atm.

It is present in the from of F₂.

Chlorine is also gas at room temperature and standard pressure.

It is present in the from of Cl₂.

The bromine is liquid under these condition.

Iodine and astatine are solids.

As we move down the group their melting and boiling points increases.

What is the acronym for DNA??
victus00 [196]
The acronym 'DNA' stands for deoxyribonucleic acid.   

DNA is used to 'code' the genetic makeup of all living organisms, and is found inside the nucleus of the cell(Eukaryotes) or just floating in the cytoplasm of the cell(Prokaryotes).  DNA is made up of 4 different pairs of base molecules(nucleotides) that are slightly different from another.  The similar molecule structure RNA(ribonucleic acid) differs from DNA in that RNA nucleotides are just slightly different from the nucleotides of DNA.  This difference is that RNA nucleotides have a hydroxide group(OH) where the DNA nucleotides just have a hydrogen atom.  
Because the DNA nucleotide doesn't have the hydroxide group it has one less oxygen than RNA nucleotides do.  This is where DNA derives the prefix "deoxy-," meaning "without oxygen."  
The prefix "ribo-" is given to molecules with a certain configuration of a set of 3 consecutive but not necessarily contiguous CHOH(asymmetric) groups.
The combined form "nucleo-" is used to imply something that has to do with the nucleus, such as the nucleus of a cell where DNA is stored in Eukaryotes.  
And finally, the ending of the acronym: "acid." DNA is an acid because the 4 nucleotides each contain a phosphate group, which are acidic.

And thus, we get our answer: deoxyribonucleic acid, and the meaning:
deoxy-ribo-nucleic acid
(without oxygen) + (has 3 CHOH groups) + (in/of the nucleus) + (acidic)
Thus, DNA is a molecule is basically an acidic molecule residing in the nucleus with 3 CHOH groups and is missing oxygen atoms.

I know this isn't really what you're looking for, but honestly I had a great time doing a little research into the name!

Hope this explains it a little! c;
