Besides oxygen exchange, the respiratory system also functions to eliminate (Click to select) . Too much of this gas can cause a(n) (Click to select) in blood pH, compromising homeostasis.

Answers

Answer: Carbon dioxide, decrease

Explanation:

Cellular respiration is a set of reactions by which organic compounds (sugars) are degraded by oxidation to inorganic substances. This process provides energy in the form of ATP and to achieve this, many reactions occur in which electrons are passed from one molecule to another, called redox reactions. In the case of aerobic respiration, the final electron acceptor is molecular oxygen, which is reduced to water.  Oxygen, like any gas, crosses the plasma membrane and then the mitochondrial membrane, and in the mitochondrial matrix it binds electrons and protons, forming water. It is in this final oxidation and in previous processes that energy is obtained. The reactions that extract energy from sugars such as glucose are catabolic reactions since a large molecule is broken into smaller molecules. For example, when glucose is broken down in the presence of oxygen, six molecules of carbon dioxide (CO2) and six molecules of water are obtained. Both CO2 and water are eliminated by lung exhalation.

In the event that this carbon dioxide is not completely eliminated, something called respiratory acidosis occurs, which is one of the disorders of the acid-base balance due to a decrease in the frequency of respirations or hypoventilation. The increase in the concentration of carbon dioxide in the blood causes the pH value to decrease. This scale is a measure of the degree of acidity or alkalinity of a substance or solution. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more alkaline. Carbon dioxide is constantly produced as the body metabolizes energy, which will accumulate in the circulation rapidly if the lungs do not remove it properly. Alveolar hypoventilation thus leads to an increase in arterial CO2 partial pressure. The increase in pressure in turn decreases the ratio of bicarbonate (HCO3) to bicarbonate pressure with a consequent increase in acidity or decrease in blood pH. The body's metabolism rapidly generates a large amount of carbonic acid (H2CO3) and non-volatile acid. The lungs normally excrete the volatile fraction through ventilation without accumulation of acid in the blood but in this case this is not possible and this accumulation of carbonic acid causes the pH to rise. This disrupts homeostasis, a form of equilibrium that is achieved through a network of feedback control systems that constitute the self-regulatory mechanisms.

When you pushed the diaphragm up what change occurred in chest cavity pressure? Explain how this change in chest cavity pressure affected the lungs.

Answers

Answer:

positive pressure

Explanation:

Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.

Explanation:

The endoplasmic reticulum is considered as the transportation system of the eukaryotic cell, and perform many important functions such as protein folding. Endoplasmic reticulum is a type of organelle which is made up of two subunits i.e. rough endoplasmic reticulum, and smooth endoplasmic reticulum. Endoplasmic reticulum performs a variety of essential cellular functions such as protein synthesis, processing, lipid synthesis, and calcium storage and its release in the body.

Answer:

So, the mitochondria are like the cell's power plant and the nucleus are the command center, then the endoplasmic reticulum (ER) is the cell's factory. This type of organelle is a packaging and storage facility. The ER is separated into two types – rough and smooth.

The rough ER looks like sheets of bumpy membrane. The bumps are just ribosomes attached to the organelle. The function of the rough ER is protein synthesis, (it's where the proteins are made). Ribosomes create amino acids that are built into proteins inside the ER. Some of the proteins are used by the cell, while others are packaged and sent out through the cell membrane for use elsewhere.

The smooth ER is a network of tubes attached to the rough ER. It is called smooth ER because it lacks ribosomes. The smooth ER is responsible for the production and storage of steroids and lipids, also known as fats. It also stores calcium ions used by muscle tissue.

C . an oceanic and a continental plate diverge
D.

Answers

Largest mountains such as the Himalayas occur where two continental plates converge

The formation of mountains occurs due to the movement of plates, which are sections of Earth's crust. Moreover, this phenomenon happens when two plates converge or collide as this causes one plate to move beneath the other and creates elevations such as mountains.

Besides this, the formation of big mountains such as the Himalayas is mainly the result of continental plates converging (plates that form continents), for example, the Himalayas formed as the Eurasian and Indian plates collided.

Answer:

formation of gametes.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Generally, cells have the ability to independently replicate themselves.

Differentiation can be defined as the process in which a cell changes from a generalized cell type into a specialized cell type for performing specific functions in the body.

Mitosis can be defined as a type of cell division that occurs in all body cells found in living organisms.

Hence, all of the aforementioned statements refer to mitosis, except formation of gametes.

In living organisms, the formation of gametes is linked or has to do with meiosis.

Blair & Rosen (B&R) plc is a U.K. based brokerage firm that specializes In building investment portfolios designed to meet the specific needs of its clients who are mostly private investors willing to invest their r savings in stocks and shares. One client who contacted B&R recently has a maximum of $500,000 to invest. The company`s investment advisor has decided to recommend the portfolio consisting of two investment funds: An internet fund where the companies are all active in internet businesses of one kind or another and the blue-chip fund which is more conservative and traditional. The internet fund has a projected annual return over the next few years of 12 %, while the blue-chip fund has a projected annual return of 9%. The investment advisor has decided that at most, $350,000 of the client`s funds should be invested in the internet fund. B&R services include risk rating for each investment alternative. The internet fund which is more risky of the two alternatives has a risk rating of 6 for every thousand dollar invested while the blue-chip fund has a risk rating of 4 per thousand dollar invested. So, for example, if $10000 is invested in each of the two investments funds, B&R risk rating for the portfolio would be 6(10) + 4(10)= 100. Finally B&R has developed a questionnaire to measure each client`s risk tolerance. Based on the responses, each client is classified as conservative, moderate or aggressive investor. The questionnaire results have classified the current client as a moderate investor. B&R recommends that a client who`s a moderate investor limit his or her portfolio to a maximum risk rating of 240. You have been asked to help the B&R investment advisor. What is the recommended investment portfolio for this client? What is the annual return for the portfolio?
