Blank makes up cell membranes​

Phospholipids : This makes up the bi-layer which is the membrane's basic structure and has great control over what can enter and exit the cell, due to their hydrophobic tails and hydrophilic heads.

Cholesterol : This also controls entry and exit of substances as it also exhibits hydrophilic heads and hydrophobic tails. It also stabilises the membrane and affects its fluidity (the more there is, the more fluid is the membrane.)

Glycolipids : Those can act as receptor molecules (essential for cell-signalling), antigens and in cell-adhesion

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
