In humans, babies that are born too small often lack the reserves to thrive, and babies that are too large are prone to difficult births. Since babies at the extremes are less likely to survive, evolutionary pressures favor moderately-sized babies. What type of selection is this an example of?

In humans, babies that are born too small often lack the reserves to thrive, and babies that are too large are prone to difficult births. Since babies at the extremes are less likely to survive, evolutionary pressures favor moderately-sized babies. What type of selection is this an example of NATURAL SELECTION

Explanation:

Charles Darwin theory of natural selection best describes that organism that best fits an environment survives while the ones that could not thrive go to extinction or die-off

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
