Cell Analogy Story
A cell can be compared to a business. The Nucleus controls all cellular functions like a Chief Executive Officer that controls all of the operations and decisions of the business. Within the business there is the cytoplasm. The Cytoplasm in a cell, harbors cell organelles and provides structure. This compares to the factory work space that contains all the working bio-machinery and the nutrients, like the raw materials, for the cellular processes. The Cytoskeleton for a cell is what provides the shape and structure to the cell. This is compared to the architecture structure of a factory. It helps to support and strengthen the structure of the building. The Endoplasmic Reticulum of a cell is the site for protein synthesis, the vesicle packaging and transport. This is compared to an assembly line of the business. This is the main work space for production of the important cell components, for example the proteins. The Golgi Apparatus of the cell is the packaging of molecules into the transport vesicles. This is compared to the packaging department of a business. The packing department is the department that packages the goods that have been prepared. The Lysosomes of the cell is actually the membrane-bound cell organelle. It contains the digestive enzymes that break down the excess or the otherwise known worn-out parts of the cell. If the cell is considered damaged beyond repair it will help it to self-destruct with a process that is called programmed cell death. This is compared to the maintenance department of a business. The maintenance department is called in when there is old worn out machinery that needs replaced and discarded. The Mitochondria of the cell is in charge of producing the energy through cellular respiration. This is compared to the power plant or the generator of the business to help the production of energy. There are a few extra parts of the cell that could not be put on the chart above. The Plasma membrane of the cell is the semi permeable that controls cellular transport. This is compared to the Logistics department of the business. This department is in control of what is shipped in and out of the business. The last one is the Ribosomes of the cell. This Ribosomes are like the protein builders or the protein synthesizers of the cell. This is compared to the factory workers of the business. The works build the products for the company.

Explanation:
The body monitors the levels of oxygen in the blood to regulate breathing. Isabel is running in a marathon and is near the finish line. She feels out of breath. How will her nervous system work to generate a reaction?
Answer:
Low oxygen pressures in the blood cause the nervous system to respond with hyperventilation.
Explanation:
In our body, the partial pressures of oxygen in the blood is a marker of blood pressure and hyperventilation.
The partial pressure of this gas may be decreasing due to lack of partial pressure of oxygen in the atmosphere that we breathe or in the great respiratory demands, that is why in this case, the partial pressures of oxygen during the marathon decrease.
When decreasing, this is captured by the nervous receptors and the CNS executes an increase in respiratory rate, generating hyperventilation so that the partial pressure of oxygen increases.
These receptors are chemoreceptors, capable of detecting the slight drop in blood pH due to oxygen deficiency associated with hemoglobin, since metabolic acidity is very common in cases of low oxygenation.

If you measure one hundred centimeters, is the distance more or less than one kilometer?
The distance measure in centimeters is less than the kilometers.
What is centimeters and kilometers?Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.
Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.
For above conclusion we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.
So, we can say that one hundred centimeters is less than the one kilometer.

There is an algal bloom in a bay in a populated area. As the leading marine biologist in the area, what is the most important thing to do, based on scientific evidence about such blooms? warn people about which food is safe to eat develop a strategy to prevent future algal blooms warn people to stay away from the affected area evacuate all wildlife from the bay
The most important thing to do is that kindly evacuate all the living forms living in the area where there is an excessive amount of algal bloom.
What do you mean by Algal Bloom?
Algal bloom may be defined as the dense layer of tiny green plants that occurs on the surface of lakes and other water bodies when there is an overabundance of nutrients on which the species of algae depends.
Algal bloom grows as a result of Eutrophication. These growing algal species consume all major nutrients like phosphorus and nitrogen and expand their numbers. As a result of this, other organisms of that area feel the scarcity of minerals and nutrients, due to this a large mass of death has occurred. Algal bloom makes the surrounding water oxygen defiecient. So, to prevent these types of activities, it is better to evacuate all living forms and provide them with the other environment.
Therefore, The most important thing to do is that kindly evacuate all the living forms living in the area where there is an excessive amount of algal bloom.

Juan has been diagnosed with mono, and the doctor wants to determine if his spleen is enlarged. Where (quadrant, etc.) will the doctor palpate Juan's abdomen? What other organs might be compressed by Juan's enlarged spleen? Given the diagnosis, why is Juan's spleen enlarged and not his stomach or kidney?
Answer and Explanation:
Where (quadrant, etc.) will the doctor palpate Juan's abdomen?Under normal conditions in general the spleen can not be palped because of its reduced size. But when it is enlarged it might be easily touched. The spleen is located under the thoracic cage (rib cage) on the left side, between the 8th and 11th ribs. This would correspond to the left superior quadrant (left hemi-belly).
What other organs might be compressed by Juan's enlarged spleen?The enlargement of the spleen and the liver inflammation are symptoms of the mono disease. This enlargement might affect some neighboring organs such as the stomach, which might be displaced and compressed.
why is Juan's spleen enlarged and not his stomach or kidney?The spleen is part of the immunological system and helps the body to fight infections and filter old bloody cells taking them out of the blood current. This organ might get enlarged because blood cells accumulate in its interior. Red blood cells are excessively stored in the spleen, resulting in anemia. The more cells the spleen retains, the larger it becomes, and hence, the more blood cells it retains and destroys. If the spleen is unproperly working, it kills too many red blood cells and accumulates many others.
The Stomach and kidney are not part of the immunity system and they do not filter blood cells, so they do not seem to be affected by their accumulation.
