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>

the man above me had the same answer i just did it as well because it's the right answer i looked it up i hope he or i help you guys <3
Answer:
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
<em>Note: The question is incomplete. The attachment below gives the complete question</em>
Explanation:
The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.
The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.
From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:
Solid 1: 10/2 = 5 cm⁻¹
Solid 2: 12.18/2 = 6.09 cm⁻¹
Solid 3: 19.0/2 = 9.5 cm⁻¹
Solid 4: 34.24/2 = 17.12 cm⁻¹
Solid 5: 65.79/2 = 32.895 cm⁻¹
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
B.
All dentist equipment is used in the mouth. Many deseases, bacteria and viruses are transmitted trough saliva, and not all of these are weak. So, that is why we clean the dental operatory, to lower the chances of transmitting anything.
