Explanation:

Definition of monocot

: a chiefly herbaceous angiospermous plant (such as a grass, lily, or palm) having an embryo with a single cotyledon, usually parallel-veined leaves, and floral organs arranged in multiples of three : monocotyledon Monocots account for a quarter of all flowering plants.

Besides having different chemical structures, what is the difference between glucose and ATP?

AVprozaik [17]

Glucose and ATP are organic compounds composed of carbon, hydrogen and oxygen. Other than these three elements, ATP contains Phosphorus and Nitrogen. Cellular respiration breaks down glucose into water and carbon dioxide producing 38 net ATP molecules. ATP is the energy containing nucleotide in cells while the energy found in glucose is used to make ATP. The key difference between glucose and ATP is the composition of these two molecules.

What is Glucose?

Glucose is a simple sugar which is widely used in living organisms. The chemical formula of glucose is C6H12O6. It is a monosaccharide which functions as a precursor for many carbohydrates found in the organisms. In plants, glucose is produced by photosynthesis and used as a substrate for energy production. In animals, glucose is a prime energy source. In prokaryotes, glucose subjects to either aerobic respiration, anaerobic respiration, or fermentation and converts into energy molecules. Therefore, glucose can be considered as one of a primary energy source of living organisms.

Glucose is broken down completely to water and carbon dioxide by aerobic respiration. It starts with electrolysis and going via Krebs cycle and electron transport chain. In the end, it converts the energy in the nutrient glucose into 38 ATP and other two waste products. Anaerobic respiration produces less number of ATP from a glucose molecule since glucose is undergoing incomplete combustion. Some microorganisms ferment lactose to lactic acid or alcohol produce energy under anorexic conditions. All these processes use glucose as the starting substrate for ATP production.

What is ATP?

Adenosine triphosphate (ATP) is the energy currency in living cells. It is a nucleotide composed of three major components; namely, ribose sugar, triphosphate group, and adenine base. ATP molecules bear high energy within the molecules. Upon an energy request for growth and metabolism, the ATP hydrolyses and releases its energy for cellular needs. Three phosphate groups are responsible for the function of the ATP molecule because the energy is stored in ATP molecule inside the phospho-anhydride bonds between phosphate groups. The most commonly hydrolyzing phosphate group of the ATP molecule is the farthest phosphate group (Gamma-phosphate) from the ribose sugar.

ATP molecule bears high energy within it. Therefore, it is an unstable molecule. Hydrolysis of ATP is always feasible via an ergonomic reaction. The terminal phosphate group removes from the ATP molecule and converts into Adenine phosphate (ADP) when the water is present. This conversion releases 30.6 kJ/mol energy to the cells. ADP converts back into ATP immediately inside the mitochondria by ATP synthase during the cellular respiration.

A. Your little sister has a severe allergy to bee stings. The last time she got stung, you watched her swell up and struggle to

Flauer [41]

Answer:

Your little sister has a severe allergy to bee stings. The last time she got stung, you watched her swell up and struggle to breathe until the paramedics got there. You also have a friend with mild asthma. When the news reports that asthma threatens the lives of more people than do allergies, you don't believe it.

This is an example of Vividness.

Explanation:

In Psychology, vividness explains that the things which influence you depend upon that how you see them or recall them vividly.
In the given situation, you don't believe the news report that asthma threatens the lives of more people than do allergies because you have seen your little sister suffered from allergy due to bee sting. The vividness of the incident makes you not to believe the report of the media.

8. What can be concluded from the evidence that coughs and sneezes are natural

andreyandreev [35.5K]

Answer and explanation:

8. What can be concluded from the evidence that coughs and sneezes are natural reflexes and from the evidence that our immune system attacks allergens?

Coughing and sneezing are natural defense mechanisms that consist of the sudden expulsion of air from the respiratory tract, with the intention of expelling any substance harmful to the body.

Allergies are the product of an exaggerated response of the body to the presence of environmental substances, such as dust, fungi and pollen, called allergens. This abnormal response is caused by an immune system previously sensitized to these substances.

Under normal conditions, the immune system is designed to defend an individual against potentially harmful elements. Coughs and sneezes are natural defense mechanisms, which are exaggerated in allergy sufferers.

9. What two possible reasons for the increase in allergies are explained in the passage?

- "Some scientists think our immune systems don't have enough to do ..." "... when our immune system have fewer germs to fight, they can get confused".

According to the excerpt, an immune system that has been inactive due to less contact with germs, looks for a way to attack any substance foreign to the body, which would be a mechanism that promotes the presence of the allergic response.

The confusion of the immune system would be given in some people by reacting in an unusual way to environmental stimuli or food, which do not affect the majority of people.

- ... "weather is warmer for longer periods now, so plants bloom longer .. release pollen, which is a common allergen".

Plant pollen is considered an aeroallergen capable of producing the response with sneezing or coughing in sensitive people.

Other evidence implies an increase in the amount of aeroallergens, as a consequence of the temperature change. A warm temperature for long periods of time promotes flowering in plants more frequently, and there is more pollen dispersed in the environment.

10. What can be concluded about the increase of allergies in the future?

In the text it can be clearly seen how, according to statistical data, the presence of allergies in more people has increased over time.

Many factors may induce an increase in the number of allergic patients in the future, such as the example provided by the passage of children less exposed to germs due to the use of increasingly available medications.

In the past, there were fewer allergies because the immune system remained active to defend the body without the help of drugs.
Additionally, the increase in processed food products may be a factor that in the future increases the appearance of allergies in the population.
Again, the environmental factor plays a determining role. Over time, many climatic changes occur, which, combined with environmental pollution, may lead to increased allergies in the future.

In the images below you will find the information of the article about allergies.
