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.

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.

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.

Answers

Answer:

A

Explanation:

The correct answer would be that the sperms are changing chemical energy to kinetic energy.

In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells.  Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.

The correct option is A.

Answers

Answer:

D. x2000

Explanation:

magnification = image(drawing size)/actual size

magnification = 40/0.02

magnification = x2000

The magnification of the diagram is x2000. So, the correct option is (D).

What is Magnification?

Magnification is the process of magnifying something. It enlarge the apparent size and not the physical size. This type of enlargement is certainly quantifiable. It also refers to the action of visually enlarging an object with the help of lenses.

This concept exist in two forms-

1. By microscope

It makes small objects appear large

2. By telescope

It makes a distant object which appear closer and the images are more clear and defined.

The formula of magnification represents the ratio of the height of the image to the ratio of the height of the object.

Magnification = image/actual size

For given example, magnification = 40/0.02

magnification = x2000

Thus, the magnification of the diagram is x2000. So, the correct option is (D).

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.

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.

During pulmonary ventilation, relaxation of the diaphragm and external intercostals ________ and air flows out of the lungs. increases the pressure in the thoracic cavity flattens the floor of the thoracic cavity increases the volume of the thoracic cavity expands the rib cage stimulates the phrenic nerve

Answers

Answer:

Increases the pressure in the thoracic cavity

Explanation:

During pulmonary ventilation, relaxation of the diaphragm and external intercostals increases the pressure in the thoracic cavity and air flows out of the lungs.

Pulmonary ventilation involves the exchange of air in the body. The exchange mainly takes place between the lungs and the the blood. When the lungs take in oxygen it distributes it to other parts of the body after which the byproduct is expelled in the form of Carbon dioxide.

The diaphragm and intercostal muscles are found close to the chest(thoracic) region such that when air is expelled it produces a similar effect such as relaxation of the diaphragm which also makes the chest muscles go down and exert pressure. This mechanism aids the expulsion of Carbon dioxide from the lungs.

Part Two: Position Paper What's your position about building roads in the rainforest? Write a paper that explains your position. Use facts from your research to support your position. How would humans and different parts of Earth be affected by the construction? Is there any argument against your position?

Answers

Answer:

We should not be building roads in the rain forest. Some reasons behind this include trees produce oxygen, animals leaving their natural habitat would not survive, and it would only increase pollution. Research states that if pollution increases any more, the Ozone protecting us will deteriorate. Other research states that if animals lose their natural habitat and have to adapt to a new environment, they are not very likely to survive. And not surviving means that the food chain will break, affecting everything above it, and that could also include us. This concludes why we should not build roads in rain forests.

Explanation:

Sorry if its short, but here <3

No roads should be build in the rainforests.

What do you mean by rainforests?

"A luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall."It's a moisture dependent vegetation.Why no roads?To build a road a vast area full of vegetation will be cut down.This will adversely affect the climate and habitats of organisms living there.This will also result in scarcity of rainfall.This results in interference of humans on the habitat of that area.

Hence, building of road should be avoided in rainforests.

Rate each question from 1 to 5 ❑How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)? ❑How much do you depend on natural ecosystems for the food you eat? ❑How important is preserving natural ecosystems to you? ❑How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future?

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.

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.
