Which statement describes how water is pulled up through the xylem to the leaves of the plant? As water exits the leaf, hydrogen bonding between water molecules pulls more water up from below. A As water exits the leaf, signals are sent to the roots to pump more water up to the leaves through the xylem by adhesion. B Evaporation from the leaf decreases the hydrogen bonds that form between the water molecules in the xylem, which helps the water molecules to be pulled up the xylem. C Evaporation of water from the leaf increases the hydrogen bonds that form between water molecules in the air, providing the energy for transport.

Option (A) is Right Answer

Explanation:

    A As water exits the leaf, signals are sent to the roots to pump more water up to the leaves through the xylem by adhesion

Water diffuse out of the stomata, this makes pressure in the xylem Water is therefore pulled upwards as it replaces the water that is lostIt goes in a ceaseless "line" up the xylem because of the attachment inside water, this importance the hydrogen bonds that structure between each water molecule Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by dispersion through the stomata

Yes it is hereditary because of the penis

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
