Answer:

1) This happens in the nasal cavity or nostrils. The cilia (nasal hairs) are the ones responsible for this in which the particles are filtered. Then in the back of the throat is where the nasal cavity and mouth meet is the pharynx.

2) This is the correct function. There are four stages of gas exchange that occur when oxygen is breathed into the body: ventilation, pulmonary gas exchange, gas transport, and peripheral gas exchange. The processes of gas inhalation, exhalation, exchange at the alveoli, transportation to the blood, and subsequent diffusion through different cellular membranes situated in body tissues are described. The lungs contain millions of alveoli, which are surrounded by capillaries. Each bronchiole ends with a collection of tiny air sacs known as alveoli. Capillaries, which are very small blood arteries, surround alveoli. These air sacs are filled with oxygen-rich air from the air you breathe in. The exchange of gases takes place here.

3) It travels down both, not just one.  The air travels passed the larynx and into the trachea. The trachea is divided into two tubes which are known as the bronchial tubes. The left one leads to the left lung and the other to the right lung. From here the air is brought to even smaller tubes known as bronchioles.

4) Air enters from the outside during inhalation to either these two openings: nostrils or external nares. The cilia serve the purpose of capturing large inhalation particles. The internal nares are the openings between the nasal cavity and the pharynx. Hence, air enters into the nasal cavity.

5) From the pharynx, air flows through the glottis to the trachea and the cycle continues. The glottis and two or three other cartilages form the larynx, a simple tubular structure in most reptiles.

The elements that are made in an average main-sequence star are helium, carbon, and oxygen.

The elements that are made in a massive main sequence star as it starts to die elements are gold and uranium,

The life cycle of a star refers to the cycles which a star undergoes from birth to death of the star.

A star changes over time through a process called stellar evolution. The lifespan of a star can vary depending on its mass, from a few million years for the most massive to trillions of years for the least massive, which is much longer than the universe has been around for now.

Answer:

The brain stem is responsible for increased blood pressure, HR etc,

Explanation:

It is made up of the mid brain, the Pons, and the Medulla.

While the Pons serve as the neurological bridge between the brain regions e.g the cerebrum and cerebellum to conduct and control certain responses the Medulla controls involuntary activities.Thus the involuntary activities listed above are controlled by the medulla.

Thus the activities of the rats which involves the dilation of pupils, erection of hair, are controlled in the pons. While increases blood pressure and the H.R are under the medulla.

Answer:

Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle  

Explanation:

The term cell cycle refers to the mechanism of DNA replication and cell division, which involves a series of sequential steps. The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events. HeLa is an immortalized cell line derived from cervical cancer cells. These cells (HeLa) contain 76 to 80 total chromosomes (instead of the 46 chromosomes that contain normal-diploid body cells), some of which are heavily mutated. These mutations can affect CDKs that control the cell cycle as well as checkpoint-control mechanisms (for example, those resulting from DNA damage), thereby cells do not enter programmed cell death (apoptosis) and proliferate uncontrollably.

Explanation:

Most islands do not have the same environmental problems as mainland places. The animals on islands were able to evolve, while mainland animals could not. Even though different islands may have similar habitats, there could be other outside factors such as pollution from humans that could harm the evolution other animals were able to get.

Answer: Island dwelling organisms could be unique to an island, similar yet different to nearby mainland organisms, and not have the same adaptations as other organisms in similar island habitats because the islands may have small changes in its environment such as climate, food sources, size, and what other species of living organisms are among the island.

When recording euthanasia be sure to note the date, animal identification information, confirmed or tentative diagnosis, euthanasia method and final disposition.

The euthanasia record is an important document for veterinary practices and should be maintained according to state and federal regulations and the policies and procedures of your practice.

When recording euthanasia, be sure to note the date, animal identification information, confirmed or tentative diagnosis, euthanasia method, and final disposition.

Another important thing to note is that euthanasia should be considered only when alternative management options are not available or have been exhausted, when quality of life is poor, and when euthanasia is in the best interest of the animal.

All reasonable steps should be taken to minimize pain and distress during the process.

Hi! It's improving sanitation :)

Explanation:

edge2020

Improving sanitation would be the most practical way to prevent the spread of cholera in a human population.

The cholera bacteria are passed through feces (poop). It is spread by eating or drinking food or water contaminated by the feces (poop) of an infected person. This occurs more often in underdeveloped countries lacking proper water supplies and sewage disposal.

Cholera is a diarrheal disease caused by the bacterium Vibrio cholera. It is almost always transmitted by water or food that has been contaminated by human waste.

Heliocentric model  represents the copernican model that is most similar to that of Aristarchus

Aristarchus of samos was an ancient greek astronomer who proposed that the Earth revolves round the Sun, suggesting a heliocentric model of the solar system. However, his model did not gain widespread acceptance during his time and the geocentric model prevailed for many centuries.

The heliocentric model later reintroduced and developed by NIcolaus Copernicus in the 16th century. Heliocentric model placed the sun at the center of the solar system, with the planets, including Earth, orbiting around it.

The trp operon is a group of genes for the biosynthesis of the amino acid tryptophan in bacteria.

Thus, the trp operon consists of five structural genes (trpE, trpD, trpC, trpB, and trpA), an operator region, and a promoter region. When tryptophan levels are high, the repressor protein binds to the operator region, thereby, blocking the transcription of the structural genes.

When tryptophan levels are low, the repressor protein is not able to bind the operator region, and RNA polymerase, which can initiate transcription of the structural genes. The trp operon is an negative feedback regulation of gene expression in bacteria as its presence inhibits the transcription of the genes responsible for its synthesis.

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .
