Homeostatic mechanisms are involuntary actions by organs, glands, tissues and cells to maintain balance within the body. If a function is disrupted the body will readjust in an attempt to maintain balance. During periods of starvation the body will break down glucose reserves in order to maintain normal glucose levels.

A chemical change involves a chemical reaction and new substances are produced. When baking soda is added to something sour (acidic) it neutralizes the acid and forms new molecules, in this case carbon dioxide and water. A physical change does not produce new substances. Phase changes such as evaporation and sublimation are physical changes. Changing the ratio of ingredients in a mixture, like adding more water to clay, does not change it chemically, but it can change some of the mixture's physical properties.

Maintaining homeostasis means that conditions are kept stable and relatively constant. Negative feedback is a mechanism used to reverse or minimize changes in a system. In this example, negative feedback is used to keep the body's glucose and insulin levels stable. Positive feedback (B) is a mechanism that Increases changes in a system. A stress response (C) describes the body's reaction to threats or pressures. Parasympathetic regulation (D) refers to activities of the nervous system, including slowing the heart rate and boosting Intestinal activity.

There are two types of nitrogenous bases: purine and pyrimidine bases. Purine bases have two rings in their structure and consist of adenine and guanine. Pyrimidine bases only have one ring in their structure and consist of thymine and cytosine (DNA) and uracil and cytosine (RNA). Therefore, the correct answer is B since thymine is a pyrimidine.

A solution that contains more hydroxide ions than hydrogen ions is a base, and bases have a pH greater than 7, so the only possible answer is choice D. 9.

The best use of the International System of Units (SI) for this situation would be the use of the micrometer as it is the smallest unit of measurement provided and the scientist is using a microscope to view the insects.

The scapula, commonly known as the shoulder blade, is above the olecranon, commonly known as the elbow. Conversely, the olecranon is distal or inferior to the scapula.

Of these orbitals, the last to fill is 6s.

Orbitals fill in the following order: 1s, 25, 2p. 35, 3p, 4s, 3d, 4p, 55, 4d, 5p. 6s, 4f, 5d, 6p. 7s, 5f, 6d, and 7p. The number is the orbital number, and the letter is the sublevel identification. Sublevels has one orbital and can hold a maximum of two electrons. Sublevel p has three orbitals and can hold a maximum of six electrons. Sublevel d has five orbitals and can hold a maximum of 10 electrons, Sublevel f has seven orbitals and can hold a maximum of 14 electrons.

While the random selection and large number of surveys sent out were a good start, to truly study the relationship between age and screen usage, it would have been better to have a few more age groups or just a direct age value from each participant rather than four large categories. As far as whether the age distribution accurately reflected the population, we don't have enough information to say if that was a problem or not. Also, the fact that each response is from just one person at the address is not a flaw but a reasonable way to get a good variety of responses

This is a single replacement reaction in which copper replaces silver. The copper combines with the nitrate ions, and the silver precipitates out. Single replacement reactions have the general form of

A + BC →AC + B. Double replacement reactions have the general form of AB + CD→ AD + CB. Synthesis reactions have the general form of A + B →AB. Decomposition reactions have the general form AB→ A+B.
