In plants, there is a conducting tissue that is located in the veins. Inside, there are xylem cells that conduct water and minerals upward from roots to leaves and phloem that conducts food. Plants have only water solutions flowing through the tubing. Animals can have one of two kinds of circulatory systems: open or closed. In animals, each blood vessel in the network is responsible for transporting nutrients and oxygen to cells and for removing wastes and carbon dioxide from cells.
Answer:
According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>
<u />
Thus the rate at which oxygen will move across the phospholipid bilayer will depend on the concentration or amount per mole of the oxygen molecule hitting the phopholipid at a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules increases.
Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid bilayer should also be maximized. the distances between the phopholipid and the vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law has been applied , and therefore maximum oxygen molecules can diffuse across.
Explanation:
Answer:
No.
Explanation:
Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms.
False there is also messenger making it 3
The answer is Integrated Pest Management. IPM involves integrating
practices in an effort to drastically reduce the population of a pest, such as
mosquitos, to below the economic injury level (EIL) and reduced risks to human
health population. IPM practices should be safe and involve the control the
pest rather than eradicate.
