Some hunter-gatherer groups for whom we have ethnographic records,

a. believed that overhunting would anger deities
b. killed large numbers of animals only every several years
c. were not especially concerned with conservation
d. all of these

option D

Explanation:

Ethnographic relates to the scientific study of specific human cultures and societies.

Cultures & traditions are held in several parts of the world, from Africa to South America to Asia so. on.

Most hunter-gatherer groups had

I) LITTLE belief in preserving natural resources, because they basically LIVED for sustenance, and even organized COMPETITIONS to reward the Hunter with the MOST KILL OR HUNTED ANIMALS

II) belief that overhunting would anger deities, as some animals like CROCODILES are considered SACRED and should not be hunted.

III) belief that hunting (like fishing) in some rivers should be seasonal or periodic like ONCE in four years etc

So, ethnographic records will actually have all of the options A, B, and C

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.
