This is because you cannot drink all water on earth. Freshwater is the only type of consumable water and there is less than 10% available. Water is very valuable for us to survive. BRANLIEST?!!!

The thing about water is that not all water on earth is able to be utilized. (Drinking) Think about it, 75 percent of the world is ocean that cannot be consumed. We need to conserve clean drinking water so that we can survive.

(01.02 HC) What inference can correctly be drawn from the diagram shown below? (2 points) Image depicts four very similar birds
stealth61 [152]
You can infer that the birds once had a common ancestor but became separated. Mutations in copying their genes stacked and caused changes in the beaks so the birds could be more well off or better adapted in their new environment.

Find the prokaryotic promoter sequences; Draw boxes around them, Circle the start codon. Then transcribe the following DNA seque
Degger [83]

Explanation:

The transcription is a process which transcribe the DNA into a molecule which could be read by the machinery to translate it into the proteins and that molecule is known as the mRNA molecule.

1.The mRNA molecule is transcribed by an enzyme called RNA polymerase which transcribe DNA in 5'to 3'direction that is DNA strand will be 3' to 5'direction therefore the strand with 3' to 5' will act as template strand.

2. The RNA polymerase binds at promoter region and there are two sequences in prokaryotes at -35 end which is TTGACA and at -10 end which is TATAAT.

3. The translation begins after the start codon which is AUG therefore proteins will be synthesized after AUG.

In the given question, both promoter sequence are present in the 5'to 3'strand

There are two start codon thus two polypeptides will be synthesized.

What level of organization in protein structure are hydrogen bonds within molecules?
Nimfa-mama [501]

Answer:

Proteins have four levels of organization. Primary structure refers to the linear sequence of the amino acids connected by the peptide bonds. The secondary structure consists of local packing of polypeptide chain into α-helices and β-sheets due to hydrogen bonds between peptide bond – central carbon backbone.
