Roots and leaves
The major driving force of water uptake in a large tree is transpiration.Transpiration is the process by which plants absorb water through the roots and release it as water vapor through the pores in their leaves. Once this water evaporates, a negative water vapor pressure is created or develops in the surrounding cells of the leaf. when this happens, water is pulled into the leaf from the vascular system, the xylem, to replace the water that has been transpired from the leaf.This pulling of water, or tension, that occurs in the leaf, will extend through the rest of the xylem column of the tree right into the xylem of the roots as result of the cohesive force holding the water molecules along the sides of the xylem tubing.The xylem is a continuous water column extending from the roots to the leaves.<span>Finally, the negative water pressure that occurs even to the roots will result in an increase of water uptake from the soil.</span>
An animal undergoing hibernation is able to maintain a regular body temperature during winter and also keeps it from starving. If it didn't hibernate, the animal would be hungry, sick, and cold... it would not being able to maintain homeostasis.
Ans.
Ruminants are those animals that gain nutrients from plant-products or foods by fermenting them in ruminant compartment before digestion. Ruminant compartment is made up of four chambers, rumen, reticulum, omasum, and abomasusm. The smallest ruminant compartment is reticulum, which helps in separation of smaller and larger food particles during digestion.
Thus, the correct answer is option D). 'reticulum.'
The answer is C trade slower on the tree develop before traits higher on the tree.
