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

Fill in the table below by writing the complementary strand of DNA that would be formed by each template strand
BlackZzzverrR [31]

Answer:

DNA strand = complementary strand

GCAAG = CGTTC

TTACG = AATGC

GATAC = CTATG

CGGAT = GCCTA

DNA strand = mRNA strand

CGATT = GCUAA

GCTTA = CGAAU

GCATC = CGUAG

TTCAT = AAGUA

Explanation: A complementary strand is not the same in base composition and sequence with the template strand. In DNA, anywhere adenine is found in the template strand, thymine is found in the complementary strand and anywhere cytosine is found in the template strand, guanine is found in the complementary strand. But in RNA, anywhere adenine occurs in the DNA template strand, uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine occurs in the mRNA strand and wherever guanine occurs in the DNA template strand, cytosine occurs in the mRNA strand.

Summarily, in DNA adenine pairs with thymine while cytosine pairs with guanine while in mRNA, adenine pairs with uracil, while cytosine pairs with guanine.

The plasma membrane is composed of both lipids and proteins. The relative concentration of each in the plasma membrane is partly
vichka [17]

Answer:

Golgi complex

Explanation:

The Golgi complex, also known as the Golgi apparatus, is a cell organelle of eukaryotic cells that functions to sort different molecules which are destined to the plasma membrane. In the Golgi apparatus, proteins and lipids from the Endoplasmic Reticulum (ER) are subsequently processed and classified to be transported to different cell locations including, among others, the plasma membrane, or vesicles which are secreted from cells by exocytosis. Moreover, this organelle also contains specific enzymes (glycosylation enzymes) that function to modify proteins in order to form glycoproteins.
