What is the difference between a bony fish and a cartilaginous fish?
blondinia [14]
Bony fish belong to Class Osteichthyes, while cartilaginous fish belong to Class Chondrichthyes. Bony fish have a bony skeleton, while cartilaginous fish have one composed mostly of cartilage. Bony fish have body coverings of scales, while cartilaginous fish are covered with dendritical projections (think shark skin).
Bony fish are found in fresh and salt water; cartilaginous fish are found only in salt water. Bony fish have gills covered by an operculum; cartilaginous fish have gill slits. Bony have no eyelids; the cartilaginous fish do. Bony fish have an air-filled swim bladder; cartilaginous fish have an oil-filled liver to keep them bouyant. Hope this helps! Whew!

What makes essential fatty acids amino acids different from ones that arent essential?
Svetlanka [38]

Answer:

\rB. nutrients that are essential cannot be made by the body, so they must be obtained from food.

Explanation:

If we look at the definition of essential fatty acids, it clearly states that these are fats which human body cannot prepare but are essential for proper functioning of body. Since body cannot synthesize them on their own, therefore we must obtain them through a diet rich in them. Two main essential fatty acids are:

  • Alpha-linolenic acid (omega-3)
  • linoleic acid (omega-6)

They play essential functions in body sucg as :

Production of hormones

Better adrenal and thyroid activity

Regulation of inflammatory and immune responses, function and development of brain.

Supporting the development of healthy skin and hair.

Option B is the best option.

Hope it helps!

Thank you
