Answer:

Gather 11 Cups And then fill each cup with 5 ounces of whole milk, next is take the first cup to add a known quantity of lactaid. As A Control take another cup and do not add any lactaid. After 1 Minute, pour a known quantity of benedicts into cups of milk. Record the colour ( blue is the least amount of glucose progressing to green, then yellow, orange, red and brick/red brown). Take another cup of milk and then add the lactaid and wait for 5 minutes... Next is add the benedicts. Record the color, repeat steps 7 - 10 adding 5 minute each time until there are no cups left ( 15 minutes, 20,25,30,35,40,45) .

For the last is graph the data and forms conclusions ..

This is the right answer.
Hope it helps.

Why was water used to dilute the substances instead of another chemical?

BabaBlast [244]

Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.

Body Type: DNA code- AGTGCCTTC RNA code- ___________ Amino Acid sequence (aka protein)- ___________________ Body Type?- ________

olga2289 [7]

Answer:

The correct answer would be:

mRNA sequence - UCACGGAAG,
amino acid sequence - Ser-Arg-Lys, and
body type - dwarf

By central dogma, we know that nucleotide sequence of deoxyribonuceic acid (DNA) form the amino acid sequence of a polypeptide chain.

Nucleotide sequence of DNA is first decoded in the form of nucleotide sequence of mRNA (messenger ribonucleic acid) under the process of transcription. The sequence of RNA is complementary to the nucleotide sequence of template strand of DNA. In addition, uracil is present in RNA in place of thymine.

tRNA (transfer RNA) then deciphers the codon sequence of mRNA into amino acid sequence of polypeptide sequence by the process of translation.

Now, given DNA sequence is AGTGCCTTC.

so, the mRNA sequence would be UCACGGAAG.

Codon sequence is UCA CGG AAG.

So, the amino acid sequence would be Ser-Arg-Lys.

Hence, the trait of showman performer would be dwarfism.

Codon sequence chart is attached for reference.

Answer:

Meat, fish and eggs.

Explanation:

Meat, fish and eggs are the foods that do not contain any or less carbohydrate, these foods are high in protein and fats. By looking on the nutrition label for the amounts per serving (in grams) of fiber and total carbohydrates, if there is no or less percentage of carbohydrates so by see the label we can say that whether the food has low or high amount of carbohydrates.
