Answer:

The correct answer is - fatty acid.

Explanation:

A phospholipid is a one of lipid molecule which is present as major component of cell membrane, that plays a significant role. Phospholipids allow for selective passage of ions and other molecules through the cell membrane.

Phospholipid is structurally similar to triglyceride except that it is made up of two fatty acids instead of three fatty acid, in phosphoplipid third fatty acid is replace wit a phosphate group, however, glycerol molecule present in both.  The phosphate group of the phospholipid is negatively-charged which makes it polar or hydrophilic head, .

Thus, the correct answer is - fatty acid.

<h3>Amino acid</h3>

Amino acid can simply be defined as those organic molecules or substances which combine to form proteins. However, amino acids are generally characterized by some key features or properties; some of these properties of amino acids includes the following:

  • They are soluble in water
  • They are base units of proteins
  • Amino acid are insoluble in organic solvent
  • Amino acids are colourless
  • They are crystalline solid
  • All amino acids however too, have at least one acidic carboxylic acid (-COOH) group and one basic amino (-NH2) group.

So therefore, the correct answer choice among the statement above about strings of amino acids which can be decoded using single letter amino acid abbreviations to a type of

secondary structure is:

Alanine luecine proline histidine alanine histidine glutamic acid leucine isoleucine cysteine glutamic acid serine. Option a is the correct answer

A derived trait of land plants is the presence of small openings that allow gaseous exchange between the plant and its environme
mel-nik [20]

Answer:

B. stomata.  

Explanation:

Stomata are openings in the surface of the plant epidermis through which gases and water vapor pass. They are formed by two elongated cells whose shape is similar to bean grain or dumbbell depending on the species.  These cells are called guard cells, and in their midst there is a slit called the ostiole.

The stomata make the exchanges between the external and internal environment of the plant. They regulate the size of the opening, so it is possible to increase or decrease the rate of perspiration of the plant.

Stomata are usually located at the bottom of the leaf, but in aquatic plants such as the water lily they are at the top and still in vertical growing plants on both sides.
