How does the addition of salt or sugar help preserve food?

Biology
1 answer:
likoan [24]3 years ago
4 0

Answer:

The addition of sugar and salt to the food material result in the increase in the osmotic pressure, which help to destroy the bacteria and help in the preservation of food.

Explanation:

addition of salt or sugar help to preserve food because

  • by adding salt to the food material it absorbs the water and high concentration of salt inhibit the growth of microbe and if the water is not present in food bacteria will not able to reproduce by this way addition of salt help in the preservation of food.
  • by adding sugar to the food material it reduces the water content which prevent the food from microbial spoilage.if the sugar concentration is high ,the bacteria to lose water and if enough water is not present bacteria will not able to grow

thus by this way addition of salt or sugar help preserve food.

Look at the number of organisms and the amount of energy in each level of the pyramid. Why do you think there are more organisms
aleksandrvk [35]

Answer:

If there wasn't a lot of organisms and energy in the productive part of the triangle, then there wouldn't be a lot of third level organisms. The energy piramid would be a lot smaller then what it is here, and maybe if the energy source was low then there might not be such a vast varity of animals in the ecosystem.

Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.

Explanation:

The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.

The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.

MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.

The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.

An experiment was performed to study the progress of cells through the mitotic cell cycle. The compounds listed below were used
Hatshy [7]
<h2>Mitotic Cell Cycle</h2>

Explanation:

a. Cytochalasin: an inhibitor of actin microfilament

  • Cytokinesis is the process by which cytoplasm is divided into two cells hence generation of two daughter cells
  • In animal cells the division of cytoplasm starts with the assembly of contractile ring
  • Contractile band consists of actin and myosin and catalyze cleavage furrow formation
  • Cytochalasin is a drug that blocks the polymerization of actin filament
  • When cytochalasin is added dividing cell fails to undergo in cytokinesis due to defective assembly of contractile band

b. Colchicine: an inhibitor of microtubule formation

  • Colchicine tightly binds with free tubulin dimer and prevents its polymerization
  • In this case mitotic spindle apparatus do not assemble and cells unable to do partitioning of chromosomes into two groups
  • Thus cell division is arrested

c. Aphidicolin: an inhibitor of DNA Polymerase activity

  • Aphidicolin is used to induce cell cycle arrest via specific inhibition of DNA Polymerase α
  • It blocks the cell cycle at early synthesis(S) phase

d. Emetine: an inhibitor of ribosome activity

  • It blocks the protein synthesis in eukaryotic cells by binding to small subunit(40 S) of ribosomes
  • It interferes with the synthesis and activities of DNA and RNA
