The over-harvesting is one of the biggest threats to endangered species.

Option: B

Explanation:

An organism or group of organism or species that is expected to reach extinction in the immediate future, either internationally or under a limited political authority, is understood as an endangered species. This may be at threat because of factors including habitat loss and poaching or over-exploitation. There are many species which are getting vanished day by day due to pollution or poaching, for an instance, pangolins, who have been hunted beyond he limits for their skin, scales, meat, and some body parts are utilized by people in making traditional medicine. The Indian and Philippine pangolin are listed as endangered while the Sunda and the Chinese pangolin are rated as critically endangered by the IUCN, which contributed to the Convention on International Trade in Endangered Species (CITES) prohibiting global trade that had something to do with pangolins or their components.

Answer from: Quest

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.
