The chemical formula for glucose is C6 H12 O6 what are the names of the elements in glucose and how many atoms of each element a
NNADVOKAT [17]
First, we have C6. The C represents Carbon, and there are six atoms present. Next, we have H12. The H represents Hydrogen, and there are twelve atoms present. Finally, we have O6. The O represents Oxygen, and there are six atoms present.

Combined, these atoms make our lovely glucose, a form of sugar that plant produce in the process of photosynthesis.

FYI most of this information can be found on the lovely search engine called Google. ;)

ethical scientist would follow scientific method they would also report accurate data and they're going to keep detailed records now an ethical scientist is not going to hide their experiment from the public the only reason you're going to hide your experiment from the public would be because you have something to hide being on ethical and it would also be unethical to make an unbiased conclusion

svlad2 [7]

Answer:

1. DNA

2. Nucleus

3. mRNA

4. Transcription

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

9. Translation

10. anti-codons

11. codon

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific  tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.

Place the 4 steps of biofilm formation, listed below, in the correct order.
makvit [3.9K]

Answer:

1. Surface (substratum) is preconditioned by environment molecules.

4. Microbes attach and detach from the preconditioned surface.

2.Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably.

3. Biofilm matures and some microorganisms escape to the plank-tonic state.

Explanation:

Biofilm is a process in which microorganism irreversibly attach and grow on the surface to produce extra cellular polymers that facilitate formation of matrix. The biofilm process takes three days for the formation after which thickness of plaque increases. There are 4 main steps in biofilm formation. Surface is preconditioned by environment molecules. The microbes attach the preconditioned surface. Establishment of extra cellular matrix and finally biofilm matures.
