1. james decided to make his mother a cake for mother’s day. as he checked the recipe to make sure he had all the items he needed, he noticed that it required 30 deciliters of milk. he already has 1 liter of milk in the refrigerator. how many liters of milk will he need to buy for the cake recipe?

2. eric and paul both made airplanes in afterschool. they decided to have a contest to see which plane could fly the longest distance. eric’s plane flew 6 meters. paul’s plane flew 68 centimeters. which plane flew the longest distance and how much father did it fly?

3. ansley and her family decided to go to the beach for summer vacation. as they prepared to leave for their trip, her father programmed their gps with the address of their beach house in destin. they would need to drive 154 kilometers to get to the beach house. as they were driving, ansley noticed a sign that said, “destin – 1000 meters”. how many more kilometers meters is it to destin? how many kilometers have they traveled?

4. cailtyn loves fish. in fact, she has 4 tanks in her room filled with a variety of tropical fish. the tanks hold 4200 milliliters, 3600 milliliters, 1500 milliliters and 2000 milliliters. she needs to empty each tank and refill them. she only has a one-liter bottle to use to fill the tanks. how many times will she need to fill the liter bottle to re-fill all of her fish tanks?

currents is the correct answer.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
