Answer:
D. Sunlight
Explanation:
Since photosynthesis provides the energy the plant needs for growth, lack of light will stunt the plant's growth.
Answer:
Pressure sensing cells
Explanation:
Merkel cells provide information on pressure, position and deep static touch features such as shapes and edges. They are tactile sensors on the business of mechanotransduction. They encode surface features of touched objects into perception, but also have to do with proprioception.
<span>By definition, the two determinants of mean arterial pressure are cardiac output and total peripheral resistance. It has been shown that Lasix decreases cardiac output and total peripheral resistance. Diuretics increase urine production, so it will lower mean arterial pressure.</span>
Answer:
They have helical thickening of lignin in their walls to prevent collapse
Explanation:
the primary function of Xylem and its conducting vessels tracheids is to provide support and tranport water and minerals in plants.
Xylem vessels have layers of dead materials in the walls called LIGNIN. Lignin is a polymer; a very strong, hard materials that stop water passage through it,because it contains dead cells,
Therefore the presence of deposit of these strong impermeable, ligified walls in its walls prevent its collapse during mass flow of water of transpiration pull.
Carbon is the correct answer hoped i helped
