xxMikexx [17]2 years ago
6 0

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.

Indicate whether each of the following occurs in the ER (E), Cytoplasm (C), Golgi apparatus (G), lysosome (L) or mitochondria (M
Lelechka [254]

Answer:

EELG

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum

(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum

(3) Degradation of misfolded ER protein ossurs in the Lysosome

(4) O-linked glycosylation occurs in the Golgiapparatus

Explanation:

1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.

N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.

The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.

2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.

Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).

The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.

3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.

4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.

Water vapor in the air forms clouds because the air can no longer hold the water vapor as it _____.
pantera1 [17]

The answer is; B

As air cools, its capacity to hold moisture reduces. This is is why as warm humid air cools, it reaches a saturation point, and the water moisture begins to form droplets. These droplets form clouds in the atmosphere.

In some protists, genetic information is transferred from one cell to the next. This transfer is called _____.
bearhunter [10]
<span>conjugation
</span><span>
Binary fission is a reproduction process wherein one cell divides asexually into two cells forming two daughter cells. into In binary fission, the chromosome is being replicated in which the resultant prokaryote is exactly the same copy of the parental prokaryote which means to say that there is no chance for genetic diversity. However, prokaryotes can still share or even exchange genes through the mechanisms of  transformation, transduction and conjugation.</span>
