Option A - Metabolism
Metabolism is a collective term for the physical and chemical changes or reactions that occur within the body.
Physiology the branch of biology that deals with the normal functions of parts living organisms.
Assimilation in biology means the absorption and digestion of food or nutrients by the body or any biological system.
Excretion is the process of removing waste and toxins from the body.
The correct answer to this question is 3. While all of these choices are the body reacting to abnormal conditions, pulling blankets over yourself when it is cold at night is not an example of a homeostatic mechanism. Homeostatic mechanisms help to regulate the body including organs, glands, tissues, and cells.
These adjustments occur in order to keep the body at a steady state. The main homeostatic mechanisms are body fluid composition, blood sugar, body temperature, blood pressure, and gas concentrations. Shivering is the body's way of trying to get the body temperature back up to homeostasis.
Increasing heart rate is how the body controls its blood pressure. The secretion of insulin is the body's way of controllling blood sugar.
The correct answer to this question is D, Oxytocin, and Antidiuretic Hormone. There are two types of pituitary glands. One is anterior, and the second is the posterior. The posterior gland is a part of the brain. Its function is secreting hormones into the bloodstream. The hypothalamus produces the hormones that the posterior pituitary glands secrete.
The Oxytocin hormone is how uterine contractions, which a woman feels during labor. This hormone is also responsible for secreting milk during breastfeeding. The other hormone, Antidiuretic, is in control of blood pressure and water balance. The posterior pituitary gland stores these hormones before they are secreted.
Option B - Water will tend to leave the cell by osmosis.
To understand what is happening here, you need to understand the principle of osmosis and tonicity.
Osmosis is the net movement of WATER and not SOLUTE across a semipermeable membrane from an area of lower solute concentration (which in this case is the cell) to an area of higher solute concentration (outside of the cell).
The ability of an extracellular solution to make water move into or out of a cell.
Glucose cannot cross the cell through osmosis. Glucose is transported across a cell through active transport and not through osmosis.
The correct answer to this question is Oxgen increase in amount due to higher reales after inspiration and since are highly required by brain function. The symbol for oxygen is O, and it has an atomic number of 8. The nuclear number means that the nucleus has 8 protons.
Oxygen has no color and no odor. It also doesn't burn, but it can support other substances ability to burn, for instance, striking a match. Oxygen is essential to all life on Earth. We need to have oxygen to breathe and live. The stars make the oxygen we have.
This question si either worded incorrectly or it is just wrong. A synovial joint is a moveable joint including the ball and socket saddle and condyloid joints.
The function of ADP molecules living in a cell is to locate and taking the energy given off by other processes which are also taking place in the cell. Sometimes this process of taking the energy during oxidation is called "capturing" the energy.
Although more people are familiar with ATP, ADP is closely related to ATP as ADP happens first. ATP has been found to be the product of ADP. These molecules are pretty similar except for the number of phosphates they have. ATP has three phosphate groups while ADP only has two. The reason for this is because the additional group gives it more energy.
There are two types of metabolism, both of which are known as catabolism and anabolism.
Catabolism is a metabolic operation which involves the breaking down of larger molecules into simpler ones. It is also called the destructive metabolism, and a very good example is the breakdown of protein into amino acids.
Anabolism, on the other hand, is a constructive aspect of metabolism. During catabolism, energy is released, and this energy is used in the anabolic process, where smaller molecules come together to form larger ones. A good example of anabolism is the synthesizing of glucose.
Anabolism is the opposite of catabolism.
An example of negative feedback from our bodies is when our temperature rises or falls due to exercise. When our body temperature rises above 98.6, which is the normal body temperature for the human body, our bodies will automatically do a few things in an effort to return to homeostasis.
Amongst these things our blood flow increases, sweating increases, temperature declines, and the body cools. These natural processes are put in place by the body in order to regulate our bodies to the conditions that they should be in. If, for some reason, the body does not perform these functions on its own outside measures should be taken.
