During intense exercise, the muscle cells require constant supply of ATPs but the supply of oxygen is low. In that case - the muscle cells of the person will switch from which to which pathway?

Answers

Answer:

Aerobic to lactic acid fermentation pathway

Explanation:

ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.

Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.

What would most likely happen to this ecosystem if all of the gray wolves were removed?

Answers

Answer:

D. The fox population would decrease

Explanation:

The food web shows that the gray wolves population are the only population that prey on the moose population. If the gray wolves were removed, the population of moose would increase significantly and would dominate the ecosystem. This means that other herbivores won't be able to compete with the moose population for the forages and vegetation in the ecosystem. The population of the other primary consumers/herbivores will reduce also. By implication, the fox which depend on other smaller preys to feed on would not have much prey to feed on. The ultimate effect of the removal of the gray wolves would lead to a later decrease in the population of the fox

Fill in the blank question. The initial effect of a stimulus on a sensory receptor is a small, local change in membrane potential called a(n)

Answers

Answer:

The initial effect of a stimulus on a sensory receptor is a small, local change in membrane potential called a(n) receptor potential.

Explanation:

The process used by sensory receptors to transform the physical energy of the sensory stimulus into action potentials, the fundamental unit of information in the nervous system, is called sensory transduction. The entrance of positive charges towards the interior (mainly Na +), will cause a depolarization; while if there is an exit of positive charges from the interior (mainly K +) then hyperpolarization will occur. This change in membrane potential is called the receptor potential. A receptor potential is then a local potential that can sometimes represent the only response that results from the transduction process, for example in the taste sensory cell.

What happens if a person has one kidney removed? 1 point a. They will continue as normal b. They will stop making urine c. They will accumulate excess urea D. They will die.​

Answers

In general, most people with a single, healthy kidney have few problems. However, some long term problems have been seen in some people.

In some people who were born with a single kidney, or had a kidney removed during childhood, there is a chance of some slight loss in kidney function later in life. This usually takes 25 years or more to happen. There may also be a chance of having high blood pressure later in life. However, the loss in kidney function is usually very mild, and life span is normal. Most people with one kidney live healthy, normal lives with few problems. - kidney . org

The inferior region of the brain stem, the __________ houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.

Answers

Answer:

The inferior region of the brain stem, the medulla oblongota houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.

Explanation:

The medulla oblongata is the part of the brain that joins the spinal cord and forms the lower part of the brain stem. In the bulb there are ascending (sensory) and descending (motor) fascicles that communicate the spinal cord with the brain, in addition to numerous nuclei or centers (masses of gray matter) that regulate various vital functions. The medulla oblongata has the function of controlling vital and unconscious elements such as the heartbeat and blood pressure. Thus, it is responsible for maintaining the heart rate and regulating vasoconstriction. Also, it manages the control of respiratory function, maintaining it at all times.

Answers

Answer:

❑How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)?  4

❑How much do you depend on natural ecosystems for the food you eat? 5

❑How important is preserving natural ecosystems to you? 5

❑How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future? 4

Explanation:

The questions are closely related to ecosystemic services and how humans make use of it. Let us first review theoretical concepts, and then discuss the rating of the questions.

Ecosystem services refer to all the benefits that human beings can get from ecosystems, not only for survival but also for good life quality. There are four types of ecosystem services:

• Provision or supply:

These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.

• Regulation:

Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pest/plague control, etc.

• Cultural:

Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, learn, enjoy spiritual/religious space, and are a source of inspiration. It is considered to be cultural patrimony and the source of scientific knowledge.

----------------------------------------------------------------------------------------------------------

I answered the questions from my personal point of view, and considering 5 as the most important topic, and 1 as the less important. So, from most important to less important is 5, 4, 3, 2, 1.

How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)?

Probably, we as species, do not need these activities to survive. However, we need them to have good mental health. These are activities that we enjoy and that produce satisfaction. Whenever we do things that we enjoy our organism secretes hormones that make us feel happy. This feeling is important when people are stress about any personal situation. So, this question does not get the highest rate, but it gets a significant one, a 4.

How much do you depend on natural ecosystems for the food you eat?

Basically, we depend on nature and the ecosystem to get food and any kind of supply. If the ecosystems are damaged and altered, there is a general disbalance, and every form of life is affected. Some species might even get extinct. If we keep damaging the environment as we are doing currently, we will get to the point of not having any supply available to survive. So this is one of the most important questions, which gets the highest rate, a big 5.

How important is preserving natural ecosystems to you?

This question is closely related to the anterior one. It is very important for us as a species to realize that we depend on nature 100%, that we need to take care of it and preserve ecosystems all around the world. With no healthy and equilibrated ecosystems, we do not get to survive. So this is the other question that gets the highest rate, 5.

How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future?

This one is kind of difficult to answer, We could say that we are 100% willing to sacrifice to make sure ecosystems stay unharmed. However, we are so used to consumption, technology, confort, an easy lifestyle, and etc, that would be really difficult for us to sacrifice everything that we are used to. Just imagine yourself giving up your cellphone or your computer. Technology is one of the most polluting industries in the world. But we depend so much on it, that seems almost impossible to imagine us without it. This is why my score for this question is a 4. Personally, I surely would sacrifice too many useful things, but I find it hard to sacrifice some others.  

Myoglobin levels are higher in Tibetans and other ethnic groups that live at high altitudes. Explain the benefit of higher myoglobin levels for individuals living at high altitudes.

Answers

Answer:

They are able to take up and store more oxygen in their muscles

Explanation:

According to Oxford dictionary, myoglobin is ''a red protein containing haem, which carries and stores oxygen in muscle cells. It is structurally similar to a subunit of haemoglobin.''

The fact that Tibetans have a high level of myoglobin implies that they are able to take up and store more oxygen in their muscles since myoglobin is involved in storage of oxygen in muscle cells. Hence elevated levels of myoglobins enables the muscle cells to work more effectively.

Excessive sugar intake is related to development of dental caries because
A. oral bacteria produce acids that dissolve tooth enamel when they metabolize sugars.
B. sugar leaches calcium and phosphorus out of teeth.
C. salivary amylase dissolves tooth enamel during carbohydrate digestion.
D. sugars make the saliva more alkaline, causing damage to tooth enamel.

Answers

Answer:

The correct answer is A.

Explanation:

Dental caries is a chronic dynamic disease or process that occurs in the tooth structure in contact with microbial deposits. Among the factors that favor the development of dental caries is the excessive consumption of simple sugars. The sugars consumed with the diet constitute the substrate of the oral microflora and initiate the process of cariogenesis. Streptococcus can ferment sugars in the diet to produce primarily lactic acid as the end product of metabolism. This lowers the pH and demineralizes tooth enamel. Cariogenic microorganisms are characterized because they are capable of transporting carbohydrates in competition with other microorganisms, which could be present in the plaque; the rapid fermentation capacity of this substrate made up of sugars and starch and its acidic capacity - acid products - and acidic acid - capable of performing various functions under conditions of extreme acidity. The marked decrease in pH will contribute to the demineralization of the tooth, favoring the appearance of carious lesions in hard tissues: enamel, dentin and cementum.

A simple test to differentiate between Staphylococcus and Streptococcus is the addition of H2O2 to a colony to see if bubbles form, which are positive for catalase. Which organism would be positive

Answers

Answer:

The Correct answer is B, Staphylococcus.

Explanation:

The Catalase test is used to differentiate Staphylococci (Catalase positive) from Streptococci (Catalyst negative). The enzyme catalase is produced by bacteria that respire using oxygen and protects them from the toxic by-products of oxygen metabolism.

Catalase positive bacteria includes strict aerobes as well as facultative anaerobes. Catalase negative bacteria maybe anarobes or facultative anarobes that only ferment and don't respire using oxygen as terminal electron acceptor.

Catalase converts hydrogen peroxide to water and oxygen gas. Though both Staphylococcus and Streptococcus are gram positive bacteria, only Staphylococcus produces catalase enzymes.
