our elements that comprise over 95% of the human body are _____. carbon, phosphorus, oxygen, hydrogen calcium, phosphorus, hydrogen, nitrogen carbon, hydrogen, oxygen, nitrogen calcium, hydrogen, oxygen, nitrogen

Answers

Answer 1
I believe the correct answer would be the third option. Our elements that comprise over 95% of the human body are carbon, hydrogen, oxygen, nitrogen. Carbon and hydrogen is the backbone of any hydrocarbon or organic compound. The cells in our body are made up organic compounds thus our body is mostly composed of carbon and hydrogen. Oxygen is also present in high percent in our body since it is important for the processes of the cells. Also, nitrogen should be present in our body in large amount since it is present in proteins which is found in our body's cells and tissues.

How does ATP supply energy for cellular activities?

Answers

ATP releases energy by breaking down the weak phosphate cell present.  The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. When a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. 
First of all 
1) The cellular activities are provided by adenosine triphosphate molecules 
2) ATP is one of the adenosine  molecules, out of three phosphate groups.
3) The energy can be released by breaking down the ATP adenosine diphosphate also known as ADP

Human beings are somewhat unusual among primates in the length of their life span beyond their productive years. this may have provided an adaptive advantage over the course of evolution and is known as ____.​

Answers

Human beings are somewhat unusual among primates in the length of their life span beyond their productive years. This may have provided an adaptive advantage over the course of evolution and is known as grandmother effect. This effect occurs when a grandmother takes care of children beyond her menopausal age, around 40 to 50 years old and is able to outlive the production years of her life. It provided the grandmother a chance to live more by taking care of her grandchildren to free her children from other tasks. It is an evolutionary phase for the woman who are past their menopausal change aside from the long term marriage from their partners. That is why, grandmothers tend to live more years compared to grandfathers.

When a person removes co2 from the lungs by exhaling, the person also removes __________ from the blood?

Answers

I think the correct term would be carbon dioxide. When a person removes co2 from the lungs by exhaling, the person also removes carbon dioxide from the blood. As the blood flows in the lungs, carbon dioxide would pass out from the blood and by diffusion to the alveoli. Then, by exhaling it is removed from the the lungs.
Final answer:

When a person removes CO2 from the lungs by exhaling, they also remove carbon dioxide from the blood.

Explanation:

When a person removes CO2 from the lungs by exhaling, they also remove carbon dioxide from the blood. Carbon dioxide is transported in the blood from body tissues to the lungs by several methods, including dissolution directly into the blood, binding to hemoglobin, or being carried as a bicarbonate ion. When the blood reaches the lungs, the dissolved carbon dioxide diffuses across the respiratory membrane into the alveoli, where it is then exhaled during pulmonary ventilation.

The endocrine system consists of a series of glands that produce chemical substances known as ________.

Answers

The answer to the question is hormones. Hormones are unique molecules that the body produces to chemically regulate certain parts of the body. For instance, testosterone is a hormone important for physiological development in humans, an especially important hormone for males.
Final answer:

The endocrine system is made up of glands that produce hormones, which are chemical substances that regulate various functions in the body. These hormones are secreted into the bloodstream and affect cells that have receptors for them, resulting in widespread and long lasting effects. Major endocrine glands include the adrenal glands, thyroid, pituitary, and others.

Explanation:

The endocrine system consists of a series of glands that produce chemical substances known as hormones. These glands include the adrenal glands, which produce hormones such as epinephrine and norepinephrine that regulate responses to stress, and the thyroid gland, which produces thyroid hormones that regulate metabolic rates. Hormones are released into body fluids, usually blood, which carries them to their target cells where they elicit a response.

The endocrine glands secrete hormones into the surrounding interstitial fluid; those hormones then diffuse into the blood and are carried to various organs and tissues within the body. The endocrine glands include the pituitary, thyroid, parathyroid, adrenal glands, gonads, pineal, and pancreas.

In contrast to neurotransmitters, hormones are not released in close proximity to cells with their receptors but are secreted into the bloodstream and travel throughout the body, affecting any cells that contain receptors for them. As a result, while neurotransmitters' effects are localized, the effects of hormones are widespread and slower to take effect but tend to be longer lasting.

Name the functional group that links two monosaccharides in a disaccharide

Answers

Final answer:

A glycosidic bond is the functional group that links two monosaccharides in a disaccharide. This bond is formed through a dehydration synthesis reaction between two monosaccharides. Examples of substances formed this way include sucrose, lactose, and maltose.

Explanation:

The functional group that links two monosaccharides in a disaccharide is called a glycosidic bond. This bond is formed when two monosaccharides undergo a dehydration synthesis or dehydration reaction. During this reaction, the hydroxyl group of one monosaccharide combines with a hydrogen atom of another monosaccharide. This process releases a water molecule and forms a covalent bond known as a glycosidic bond, linking the two sugar molecules. Important examples of disaccharides include sucrose, lactose, and maltose, each consisting of specific monosaccharides linked through glycosidic bonds.

Why does muscle account for such a large portion of your body mass?

Answers

Muscle is the part of the body that is attached to the bones and are responsible mostly for body's locomotion. There are three types of which: (1) skeletal, (2) cardiac, (3) smooth. 

This part of the body is compact and thus has a greater density because it occupies larger mass for a given volume. 

                         density = mass / volume

Because it has great density then, the mass is also large. Thus, this accounts for a large portion of the body mass. 

Hemoglobin is a protein in red blood cells that binds to oxygen. which physiological changes that naturally occur in the body reduce hemoglobin\'s affinity for oxygen?

Answers

Final answer:

Hemoglobin's affinity for oxygen decreases with higher carbon dioxide levels and lower blood pH, higher body temperatures, and in conditions like sickle cell anemia and thalassemia, which alter the red blood cells' structure or hemoglobin content.

Explanation:

Hemoglobin's affinity for oxygen can be reduced by several physiological changes in the body. High levels of carbon dioxide (CO2) lead to increased production of hydrogen ions, which decreases blood pH. This condition, known as acidosis, causes oxygen to dissociate more readily from hemoglobin, shifting the oxygen dissociation curve to the right. Similarly, an increase in body temperature, often a result of increased muscular activity, also reduces hemoglobin's affinity for oxygen. Certain diseases, such as sickle cell anemia and thalassemia, negatively affect red blood cells' shape or hemoglobin levels, thereby reducing their oxygen-carrying capacity.

"a simple scoring model for project evaluation requires":

Answers

Final answer:

The correct option is: score values assigned to each criterion in terms of its rating. A simple scoring model for project evaluation involves assigning weights and scores to various criteria, followed by multiplying these to arrive at a total score for each option. This method provides a quantitative basis for comparing and deciding on projects or options.

Explanation:

The simple scoring model for project evaluation elaborated upon involves several steps to ensure a comprehensive assessment. Initially, each criterion is assigned an importance weight ranging from 1 (least important) to 10 (most important) or could be expressed as a percentage out of 100. This flexibility allows evaluators to differentiate the significance of various criteria accurately. It is also mentioned that criteria can share the same weight, providing further adaptability in the evaluation process.

Following weight assignment, options are scored according to their performance against each criterion. These scores mirror the assigned weights in terms of scale, allowing for a nuanced assessment of how well each option aligns with the criteria. The next step involves multiplying the weight by the score for each criterion, which then adds up to yield a total score. This aggregated score forms the basis for decision-making, enabling evaluators to quantitatively assess the merits of different options or projects.

In a more specific scenario, such as a student project, the distribution of points among criteria is predetermined, guiding students on what aspects are crucial for achieving a higher grade. The flexibility of scoring and weighting allows for a customized evaluation that can adapt to various projects' unique demands and objectives.

The ________ of exercise determines whether carbohydrates or fat is the predominant source of energy production

Answers

The correct term to fill in the blank would be intensity. The intensity of exercise determines whether carbohydrates or fat is the predominant source of energy production. During high-intensity workouts, it is the fat that is used as the source of energy production while low-intensity exercises would only use the carbohydrates present for energy.

Exercise intensity dictates whether the body uses carbohydrates or fat as its main energy source, with low-intensity exercise favoring fat and high-intensity exercise favoring carbohydrates due to the aerobic and anaerobic metabolic pathways involved.

The exercise intensity determines whether carbohydrates or fat is the predominant source of energy production. During low-intensity activities, the body primarily uses aerobic metabolism, which is efficient at producing large amounts of ATP, and fat is the primary energy source. For high-intensity activities, where more ATP is needed quickly, the muscles rely on both anaerobic and aerobic metabolism, with carbohydrates being consumed more rapidly for immediate energy.

Fatty acids are favored during low-intensity exercise due to their abundant storage in the body, while glucose is primarily used during high-intensity activity, which relies more on anaerobic metabolism due to the limited oxygen available. However, the body's glycogen stores (from which glucose is derived) can be depleted, leading to fatigue.

It's important to note that even though fat reserves provide a more substantial energy source for prolonged exercise, carbohydrates are still utilized and are essential for shorter, more explosive movements where quick energy is necessary.

Bias can occur in sampling. bias refers to

Answers



Bias can happen in sampling. The propensity of a sample statistic to systematically under- or over-approximate a population is referred to as bias.

 

 

To add, in statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others.

 

The following are some types of biases in Statistics:

 

Selection bias includes individuals being more likely to be chosen for study than others, biasing the sample. This can also be termed Berksonian bias

 

In statistical hypothesis testing, a test is said to be unbiased if for some alpha level (between 0 and 1), the probability the null is not accepted is less than or equal to the alpha level for the entire parameter space defined by the null hypothesis, while the probability the null is rejected is greater than or equal to the alpha level for the entire criterion space interpreted by the alternate hypothesis.

Bias in sampling refers to any tendency that prevents unprejudiced consideration of a question. In the context of surveys and sampling, bias can occur due to the wording of questions, the methodology of data collection, or the self-selection of survey respondents. For example, an internet survey might be biased if only certain groups of people choose to respond, or a question in a survey about organic food might elicit biased responses due to its phrasing.

Bias can significantly alter the outcomes of a survey or poll and thus needs to be minimized to ensure more accurate results. For instance, Kenneth Rasinky noted that the use of terms such as "assistance to the poor" instead of "welfare" can cause respondents to indicate stronger support, despite the terms having the same meaning. The selection of respondents (like with internet surveys) can also lead to bias if the sample is not representative of the population. In addition, crafting questions in a survey is crucial as biased questions might lead respondents toward a specific answer, like the flawed example of proving chocolate ice cream's popularity by asking respondents if they simply like the flavor. A more neutral and comprehensive approach in both language and methodology is necessary to reduce bias in surveys.
