Select all of the food items where microbial growth is controlled by means of osmotic pressure.

1 answer:

5 0

The answer would be:
Jellies
Salt cured meats
Honey

High osmotic pressure can be used as a natural preservative. In high osmotic pressure, the microbes will hardly survive as their surrounding concentration is too high and induce severe osmosis. The osmosis will take the microbes water, makes it shrink continually lead to the microbes death.
In those 3 foods, there is a high concentration of sugar or salt that increase the osmotic pressure.

g Choose the correct answer from the list. Group of answer choices DNA sequences that are deduced by comparing many related DNA

REY [17]

Answer:

Explanation:

Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.

sveta [45]

Answer:

Starch is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

Cellulose is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

Glycogen is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.
