Component of a phospholipid?

Biology
1 answer:
slamgirl [31]3 years ago
8 0

Answer:

  • Phosphate group head
  • Two fatty acid tails

Explanation:

A phospholipid is made up of a phosphate group head and two fatty acid tails. They are connected by a molecule of glycerol.

To form cell membranes, phospholipids line up with their hydrophilic (water loving) heads on the outside of the cell and their hydrophobic (water hating) tails inside.

A second layer of phospholipids forms with the heads facing inside the cell and tails facing away. This forms a double layer - with the phosphate group heads on the outside, and fatty acid tails on the inside. This double layer, called a lipid bilayer, forms the cell membrane.

Choose the statement that describes processes of receptor-mediated endocytosis, exocytosis, and the changes in the membrane orga
Elis [28]

Answer:

a. Endocytosis involves the opsonization of a receptor and its ligand in clathrin-coated vesicles, along with the inward budding of the plasma membrane. In exocytosis, waste material is enveloped in a membrane that fuses with the interior of the plasma membrane via attachment proteins.

Explanation:

Endocytosis: entails the external binding of a ligand to its receptor which is located on the external side of the plasma membrane. The membrane buds inwardly for internalization to occur.

Exocytosis: material that has been processed inside the cell is transported by vesicles which fuse to the internal side of the plasma membrane and ultimately transported to the outside of the cell.

Which trait makes the seaweed diffrent from the other orgainisms in the tree
QveST [7]

Answer:

Photosynthetic autotroph

Explanation:

Plants, algae/seaweed and some bacteria can use photosynthesis to turn light energy, carbon dioxide and water into glucose and oxygen. The glucose, or sugar becomes the food for these organisms.

Since they can produce their own food, they are called producers, but they are also called autotrophs. "Auto" meaning self, and "troph" meaning nutrition. Therefore, the correct choice is: Photosynthetic autotroph.
