<span>When plants moved on the land they had to adapt to new environment and </span>to deal with new <span>problems. The main problem for plants was to figure out how to regulate water loss within the cells. One of the solution was the formation of the waxy covering on top of leaves-cuticle, which evolved on the surface of leaves to reduce water loss. Another problem for plants was to figure out how to obtain resources from soil and air, so they developed vascular tissue to transport water/sugar within the plant.</span>

Answer: The question is not complete, here are the options.
Which statements best describe this scenario? Check all that apply.
A. The potato plant is parasitic.
B. The dodder plant is parasitic.
C. The potato plant will grow stronger.
D.The potato plant stays alive because of
E. The dodder plant stays alive because of the potato plant.
The correct options are A and E.
Explanation:
This is because dodder plant is a parasitic plants that survive and live on the host plants there by causing harm or destroying the host because it survive on the resources needed for the host survival. Dodder plants twine around the potatoes and obtain nutrients and water from the potatoes through it root system.

Answer:
Explanation:
The main function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept these receptors to get into the cells, causing infections.
