During endocytosis and exocytosis, cells _____.

A) take in what they need and expel what they don't need
B) move water in and out through the cell membrane
C) actively transport molecules across the cell membrane

Answers

Answer 1

the answer is letter A

Answer 2

Answer:

Take in what they need and expel what they don't need. (Ans. A)

Explanation:

Endocytosis and exocytosis are two active transport processes which are helping macro molecules present in the cytoplasm to move inside or outside the cell across the plasma membrane. It is an energy requiring movement.

Endocytosis is known as a process which is capturing the particles from outside the cell by engulfing of them with the cell membrane. Endocytosis is mainly two types:

1) Phagocytosis, in this process cell is engulfing whole particle. It is also known as cell eating.

2) Pinocytosis, in this process cell is engulfing already dissolved food. It is also known as cell drinking.

Exocytosis, in this process where vesicles fusing with the plasma membrane which helping them to move substances out of the cell.

Suppose you have a population of 150 butterflies, but a wildfire devastates the population and only 24 butterflies survive. What percent does the colony decrease by?

Answers

Answer:

The colony decrease by [tex]84[/tex]%

Explanation:

Given -

Total population of butterflies before devastation (P) [tex]= 150[/tex]

Total Population of butterflies that survived after the devastation [tex]= 24[/tex]

Total population of butterflies that did not survived [tex]= P-p[/tex]

Substituting the given values in above equation, we get-

Total population of butterflies that did not survived [tex]= 150 -24[/tex]

Percentage by which the butterfly colony decreased [tex]= \frac{P-p}{P} * 100\\= \frac{150-24}{150} * 100\\= 84[/tex]%

Final answer:

The butterfly population decreased by 84% after the wildfire, calculated by dividing the decrease of 126 butterflies by the original population of 150 and then multiplying by 100.

Explanation:

To calculate the percent decrease in the butterfly population, we subtract the number of survivors from the original population to find the decrease in number, and then we divide that number by the original population and multiply by 100 to get the percentage. In this case, the original population was 150 butterflies and after the wildfire, only 24 survived.

The decrease in number is 150 - 24 = 126 butterflies. The percent decrease is (126 ÷ 150) × 100 = 84%. So, the butterfly population decreased by 84% after the wildfire.

The large surface area in the gut directly facilitates _____.

Answers

Answer:

B. Absorption

Explanation:

Absorption is a process that takes place in the small intestines or ileum of the GI tract, in which simple and soluble nutrients are absorbed into the blood stream.Absorption is enhanced by several adaptations of the gut such as large surface area of the gut which directly facilitates absorption of nutrients.Presence of villi and microvilli in the gut increases the surface area for absorption of nutrients in the ileum.
Final answer:

The large surface area in the gut, boosted by structures called villi and microvilli, facilitates the absorption of nutrients and water from ingested food. It also plays a role in the conversion of liquid chyme residue into semi-solid feces.

Explanation:

The large surface area in the gut directly facilitates the absorption of nutrients. The surface of the gut is filled with structures called villi and microvilli, which increase the surface area and therefore the gut's ability to absorb nutrients. With their vast surface area, the gut can process huge amounts of food (up to 10 liters), liquids, and GI secretions a day, efficiently absorbing ingested food, electrolytes, and water.

The absorption doesn't only benefit nutrient acquisition but also allows for the absorption of water, converting liquid chyme residue into semi-solid feces in the process. In addition to this, the presence of around 100 trillion bacteria in the human gut also play a role in digestion and nutrient absorption.

And finally, the small intestine, with its villi and microvilli, is responsible for the absorption of most carbohydrates and proteins. Interestingly, bile salts and vitamin B12 are absorbed mostly in the terminal ileum region of the small intestine.

Final answer:

Nuclear energy is highly efficient and provides a steady and reliable source of power, which contributes to the stability of power grids. The infrastructure for nuclear energy is already well-established. In the future, nuclear fusion could offer an even safer and cleaner source of energy.

Explanation:

Another advantage of using nuclear energy is its high energy density compared to traditional sources of energy. This means that nuclear energy is highly efficient, as it can produce a significant amount of energy from a relatively small amount of fuel. Additionally, nuclear energy provides a steady and reliable source of power, unaffected by changes in weather or raw material prices, thus contributing to the stability of power grids.

Furthermore, the techonology and infrastructure for nuclear energy are already well-established, unlike for some renewable energies where extensive development and scaling are still needed. For example, nuclear fission power plants are already present across the world and provide a significant quantity of the world's electricity.

Future technologies such as nuclear fusion can also provide an even greater reduction in greenhouse gas emissions while utilizing more abundant and less hazardous fuels than nuclear fission. Scientists believe that fusion reactors are nearly here, representing a safer, cleaner and more abundant potential source of energy.

How is homeostasis important to enzymes? Please Explain your answer.

Answers

Homeostasis is important to enzymes because in order to function properly, they need to be in prime conditions and keeping homeostasis, a consistent internal environment (right temperature, right pH, right glucose levels in blood, etc). If homeostasis is not kept he enzymes will not be able to work properly. For example, if temperature get too high the enzymes will denature (get destroyed basically) and will be unusable, if temperatures get to low the bonds the enzyme has will get to stiff and substrate won’t get able to bond to it, both slowing enzyme production. There are other examples but basically homeostasis is necessary for consistent and fast enzymes.

Homeostasis is vital to enzymes as it maintains conditions for optimal enzyme activity. It includes mechanisms that regulate temperature and pH to preserve enzyme structure and function, and it also involves feedback mechanisms for maintaining equilibrium in the body's metabolic processes.

Importance of Homeostasis to Enzymes

Enzymes are biocatalysts that facilitate almost all biochemical reactions in the body, but they require specific temperatures and pH levels to maintain their active site conformation and function properly. Homeostatic mechanisms work continuously to regulate internal conditions, such as temperature and pH, ensuring that enzymes can perform their roles efficiently. For instance, thermoregulation is a form of homeostasis that prevents enzymes from denaturing due to high heat or becoming less active in colder temperatures.

Moreover, the regulation of enzyme activity is a key aspect of maintaining homeostasis within cells. This regulation allows for enzymes to be activated or inactivated as needed, enabling cells to respond to changes and maintain equilibrium. In essence, homeostasis and enzymes work together to ensure that the body's metabolic processes operate smoothly. Feedback mechanisms also play an essential role in homeostasis, with negative feedback loops acting to reverse changes and positive feedback loops amplifying them. For example, when body temperature deviates from the ideal range, feedback mechanisms will trigger responses to bring it back to normal, much like the adjustments made by a thermostat to maintain a steady temperature in a home.

A 45-year-old man had coronary artery stents placed 2 days ago. Today, he is in severe distress and is reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mm hg, respiratory rate is 28 breaths/min, and oxygen saturation is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Which condition led to cardiac arrest?

Answers

Answer:

In the particular case, acute coronary syndrome (ACS) have occurred in the cardiac arrest. The ACS refers to a condition that arise due to the decrease of blood flow in the coronary arteries, such that the segment of the heart muscle is not able to function properly or dies. Some of the signs and symptoms of ACS are chest pain and discomfort, pain rising in your chest and in the arms, shoulders, neck, or jaw, indigestion, nausea or vomiting, shortness of breath, unusual fatigue, excessive sweating, restlessness, dizziness, or fainting.

Answer:

The given case is a result of acute coronary syndrome.

Explanation:

Acute coronary syndrome is a term given to the three kinds of coronary artery disorder, which are related to the sudden splitting of plaque within the coronary artery. The condition generally results from the accumulation of plaques or fatty deposits in and on the walls of the coronary arteries, that is the blood vessels that transmit nutrients and oxygen to the muscles of the heart. When the deposit of the plaque splits or ruptures, the formation of blood clot takes place. This clot prevents the flow of the blood to the muscles of the heart.

The impact was where modern day Yucatan is located, and it released such an enormous energy that it managed to change the face of the Earth. The explosion itself managed to kill off pretty much everything nearby, but there was also a very hot wave that circled the whole planet. Enormous amounts of dust and ashes were released into the atmosphere that blocked the Sun, and the volcanoes all over the globe were triggered. This caused major climate and environmental changes, leading to a mass extinction, with the most noticeable victims being the dinosaurs.

Explanation: E2022

For each data set, the aspect that is likely to cause inconsistent evidence is outliers for both Data Set I and Data Set II, and inaccuracy for Data Set III."

"The correct aspects of the data likely to cause evidence obtained from each data set to be inconsistent are as follows:

Data Set I: Outliers

Data Set II: Outliers

Data Set III: Inaccuracy

 For Data Set I, the values are relatively consistent, with most measurements clustering around the correct value of 195, except for one value, 540, which is significantly higher than the rest. This extreme value is an outlier and is likely to skew the results, leading to inconsistent evidence. Outliers can significantly affect the mean and other statistical measures, thus causing inconsistency in the data analysis.

For Data Set II, the values are spread out around the correct value of 15, but there is no single value that stands out as drastically different from the rest. However, the range of the data is quite wide, and there are several values that are somewhat distant from the correct value. This variability in the data can be attributed to outliers, as there are multiple values that deviate from the central tendency. These outliers can lead to inconsistent evidence when analyzing the data.

For Data Set III, the values are clustered closely together, with all measurements ranging from 48 to 53. However, the correct value is given as 65, which is substantially higher than any of the measured values. This indicates that the measurements are not accurate; they are consistently lower than the correct value. In this case, the issue is not with outliers but with the accuracy of the measurements. The data consistently misses the mark, suggesting a systematic error or bias in the measurement process, leading to inaccurate evidence.
