In a typical cell membrane, phospholipids arrange themselves to form a bilayer. This bilayer is a thin membrane which is considered a polar membrane composed of two layers of lipid molecules. This serves as a barrier around the containing cells.
Explanation:
Transpiration, plant breathing, is when plants absorbs water from the roots using the xylem and phloem and takes them to the leaves where they exit as water vapour via the stomata (tiny openings). Through transpiration plants are able to cool themselves and produce their own food using the process of photosynthesis.
Temperature is a measurement of the average kinetic energy of the molecules
in an object or system.
Speciation! Speciation occurs when a single species becomes two or more separate populations by a geographical barrier. This changes each population’s environment which forces them to adapt. Eventually these populations will become so different from each other that they will not be able to interbreed populations and create fertile offspring. This is what makes them different species, but they still share a common ancestor.
