Answer:
C. K+ ions flow out the the guard cells and water flows out the cells.
Explanation:
The turgidity of the guard cells allows the opening and closing of the stomata. This is especially necessary when it comes to water conservation in plants. In order for the cells to become turgid or flaccid, there must be the influx and out ward movement of water via osmosis.
In order for this the occur the osmotic pressure of the cellular environment must change and this is done by changing the solute concentration.
The pumping in of K+ ions out the cell allows the solute concentration to decrease and this in turn encourages the movement of water across a concentration gradient through a semi-permiable membrane.
The water leaves the guard cells and they become flaccid. This causes the stomata to be covered.

Answer:
systemic lupus erythematosus
Explanation:
Systemic lupus erythematosus (SLE or just lupus) is a chronic inflammatory disease of autoimmune origin, the symptoms of which may appear in various organs slowly and progressively (in months) or more rapidly (in weeks) and vary with phases of activity and remission. Because it is a disease of the immune system, which is responsible for producing antibodies and organizing inflammation mechanisms in all organs, when a person has SLE they may have different types symptoms and various body locations. Some symptoms are general such as fever, weight loss, loss of appetite, weakness and discouragement. Others, specific to each organ such as joint pain, skin blemishes, pleural inflammation, hypertension, and / or kidney problems.
The main cause of this disease is the imbalance in the production of antibodies that react with proteins in the body itself and cause inflammation in various organs such as the skin, mucous membranes, pleura and lungs, joints, kidneys, etc.). Thus, we understand that the type of symptom a person develops depends on the type of autoantibody the person has, and that as the development of each antibody relates to the genetic characteristics of each person, each person with lupus tends to have clinical manifestations. specific and very personal (symptoms).
Autoantibodies are antibodies directed to the body's own cells and tissues. Normally, the immune system differentiates the body's own proteins from foreign proteins, forming antibodies only against those identified as potentially dangerous.

When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor
Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.
Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.
<h3>How does transcription factors affect gene expression?</h3>
Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control
