Answer:

Tapeworms are a parasite of humans

Explanation:

Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae. If you ingest certain tapeworm eggs, they can migrate outside your intestines and form larval cysts in body tissues and organs (invasive infection).

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one
netineya [11]

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because <u>the two sides of a cell membrane face different environments and carry out different functions. </u>

<u></u>

Explanation:

<u>PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .</u>

<u>PROTEINS -:</u> The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: <u>integral and peripheral.</u> As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

<u>LIPID -:</u> Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both <u>hydrophilic and hydrophobic regions.</u>

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

<u>CARBOHYDRATES</u> -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.

The answer is Cells.

Explanation:

  • The chart is a basic molecular design of multicellular organisms.
  • Atoms, molecules, cells, tissues, organs, organ systems are the building blocks of the human body which combine together on the basis of similar function or structure to achieve various body functions.
  • Atoms form chemical bonds with other atoms and form molecules.
  • Molecules combine together to form cells.
  • Cells are the basic functional and structural units of life.
  • Cells that perform similar functions combine together to form tissues.
  • Two or more kinds of tissues that perform similar functions combine to form organs.
  • Organs, in turn, form organ systems such as the respiratory or cardiovascular systems etc.
