Answer:
Explanation:
Plant transport systems move energy from leaves and raw materials from roots to all their parts. The xylem (tissue) moves water and minerals obtained from the soil to all other parts of the plants.
Answer:
Negative feedback has the function of controlling and regulating the processes of a system. Without such a mechanism there would be no balance in the body. As such, it is responsible for maintaining balance within the system, counteracting or modifying the consequences of certain actions, that is, it seeks to reduce the effects of external aggressions.
Explanation:
When an internal or external variable of the body changes with respect to normal limits, a response is triggered that reverses the change. In this case, we are in the presence of a negative feedback. In negative feedback there are normally three parties involved: the so-called receptor, the control center, and the so-called effector. The receptor is the organ or tissue that intervenes in the negative feedback process, recording the values of some variable of the organism; these variables can be very different, for example temperature, blood pressure or blood glucose concentration. The information collected by the receiver is continuously sent to the control center. When the received values go out of the normal ranges, the control center will send orders to the effector organs so that they begin to function in a certain way that helps to return the values of the variable to the normal values in basal state.Negative feedback is the main control mechanism of homeostasis and as such is essential to keep the different parameters of the body between the values in which it can perform its functions. If negative feedback didn't exist, we would die. In fact, when negative feedback control mechanisms fail, we have to resort to medicine to help the body maintain homeostasis.

Answer:
is more steeply sloped than the windward side
Explanation:
The wind is the primary agent that moves the sediments and creates sand dunes in the deserts. When the wind starts to slow down it loses its power to carry the sediments so it starts to deposit them. As it does, a hill of sand is starting to form, called a sand dune. The wind will constantly be bringing new sediments, and the windward side is the one that gets them, while the leeward side doesn't. This results in the windward side to be much larger, but also to have much lower angle of fall, while the leeward side is having a very steep slope as it is constantly building on the top, but not the rest of it.
