It tells the audience if the results support or contradict the hypothesis

Explanation:

When a scientist describes the materials that she used and how she performed her experiments, it tells the audience if the results supports or contradicts the hypothesis.

A hypothesis formulation helps to test a scientific claims.
Experiments are usually hinged on well designed hypothesis.
From the hypothesis, one can be sure the experiment is tuned and designed within the scope of the observation desired to be tested.
This is why the materials used and procedures followed in an experiment can tell if the results supports or contradicts the hypothesis.

Liposomes consist of ________ bilayers that enclose an aqueous compartment where drugs can be contained for delivery to specific

Anna35 [415]

Answer:

Phospholipid bilayer

Explanation:

Liposomes are vesicles are spherical in shape. They consist of at least one phospholipd bilayer most especially phosphatidycholine. Liposomes are artficial vesicles similar to a membrane, because it has an hydrophilic core surrounded by a hydrophobic lipid bilayer.

Liposomes are artificial prepared and are used for the transportation of substances like drugs and nutrients between cell parts, outside of the cell and into the cell.

In liposomal drug delivery, the liposome fuses with other internal cell membranes at the site of action and releases its liposomal content.

Which is an advantage of using renewable resources

Sphinxa [80]

Answer:

Explanation: Renewable source are energy that is derived from the environment this include sun, wind. This energy have been utilized by many nations and companies for their activities. Fossil fuel is an example of non- renewable. The advantage of renewable energy include; It ability to be available all the time, they are renewed and always available this include sun, wind.

They are cost efficient this is because renewal of this energy is at no cost,they are available in the environment and can be channel for use.

They require no cost of transportation unlike other fossil fuel that will be moved from one place another and they are eco-friendly they do not bring fear of ozone layer depletion and green house gases.

How many possible open reading frames (frames without stop codons) are there that extend through the following sequence? 5'... C

fenix001 [56]

Answer:

There are 4 reading frames without stop codons.

Explanation:

1) To find the possible reading frames you need to separate your sequence in codons (trios) for the 5'-> 3' sense, first, excluding the first nucleotide, then excluding 2 nucleotides and then not excluding nucleotides.

5'... C TTA CAG TTT ATT GAT ACG GAG AAG G... 3' NO STOP CODON

5'... CT TAC AGT TTA TTG ATA CGG AGA AGG... 3' NO STOP CODON

5'... CTT ACA GTT TAT TGA TAC GGA GAA GG... 3'

2)Then you find the complementary sequence (which you already have)

3'... GAA TGT CAA ATA ACT ATG CCT CTT CC... 5'

3'... GA ATG TCA AAT AAC TAT GCC TCT TCC... 5'

3'... G AAT GTC AAA TAA CTA TGC CTC TTC C... 5'

3) Next, you have to obtain the reverse complementary

CCT TCT CCG TAT CAA TAA ACT GTA AG NO STOP CODON

CC TTC TCC GTA TCA ATA AAC TGT AAG NO STOP CODON

C CTT CTC CGT ATC AAT AAA CTG TAA G

4)Now you need to find start (AGT in terms of DNA) and stop codons(TAA, TAG, TGA, also in terms of DNA), in 5->3 and de reverse complementary.

As you can see, you have for open reading frames that lack of stop codon, unfortunately, they also lack of AGT, the start codon.

I added a table where you can find thestart and stop codons as well as the proteins that they translate to in terms of RNA.

I hope you find this information interesting and useful, good luck!
