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: Young rivers are channels that are deeper than they are wide, have a very fast flow, and contain frequent waterfalls and rapids
The dilution factor in order to end up with 96 colonies of bacteria is 0.23 × 
.
For calculating the colony forming unit bacteria;
Colony-forming unit (CFU or cfu) is a measurement of live bacterial or fungi cells and is used to calculate the colony-forming unit of bacteria. CFU counts only viable cells as opposed to direct microscopic counts, which count all cells, both living and dead, using a hemocytometer. Colony-forming units per milliliter (CFU/mL) for liquids and colony-forming units per gram (CFU/g) for solids are used to indicate the results for convenience. The miles and Misra method can be used to compute CFU, which is helpful for assessing the microbiological load and severity of illness in blood and other samples.
∴ cfu/ml = (no. of colonies x dilution factor) / volume of culture plate
23 x cells per mL = 96 × dilution factor
Dilution factor = 23 × / 96
Dilution factor = 0.23 ×
Therefore, the dilution factor in order to end up with 96 colonies of bacteria is 0.23 × .

<span><span>There are choices for this question namely:
a. Her waist is 36 inches.
b. Her triglyceride level is 140 mg/dL.
c. Her blood pressure (BP) is 128/84.
d. Her fasting blood sugar (BS) is 108 mg/dL.
The correct answer is that </span>her waist is 36 inches. The criteria for metabolic syndrome include a large waist circumference (>35 inches for women, >40 inches for men), <span>high triglyceride level (>150 mg/dL), reduced HDL or good cholesterol (<40 mg/dL), elevated blood pressure (>130/85 mmHg), and elevated fasting blood sugar (>100 mg/dL). While her fasting blood sugar is elevated at 108 mg/dL, more specific criteria is the waist circumference.</span></span>
