Answer:

Extinctions occur at higher rates during times of ecological stress when populations and species are poorly adapted

Explanation:

Evolution has made it known to us that organism goes to extinction as a result of changes in ecological stress without being able to adapt by this organism to the new changes, hence; leads to extinction.

Charle's darwin theory of natural selection discuss about '' survival of the fittest'' when an organism fails to survive during harsh environment changes, it leads to extinction of such organism. Dinnosaur were able to go into extinction as a result of environmental changes which they are unable to adjust, thus; they went to extinction.

MArishka [77]

Answer:

This question appears incomplete but The correct option is the last option

Explanation:

Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.
