How does your body get the energy that it needs to do all of its daily activities? Describe the energy conversion that take place.

Answers

Answer 1
Final answer:

The human body gets the energy it needs for daily activities through cellular respiration. Glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and ATP. This energy conversion takes place in several steps, including glycolysis, the citric acid cycle, and the electron transport chain.

Explanation:

The human body gets the energy it needs to do daily activities through a process called cellular respiration. This is the conversion of food into energy at the cellular level. During cellular respiration, glucose (a type of sugar) is broken down in the presence of oxygen to produce carbon dioxide, water, and ATP (adenosine triphosphate), which is the main source of usable energy in cells.

Here is the step-by-step process of energy conversion that takes place:

Food is ingested and broken down into smaller molecules. For example, complex carbohydrates like starches are broken down into simple sugars like glucose.Glucose enters the cells and undergoes a series of chemical reactions called glycolysis, which occurs in the cytoplasm. During glycolysis, glucose is converted into pyruvate and a small amount of ATP is produced.If oxygen is present, pyruvate enters the mitochondria where it goes through a series of reactions known as the citric acid cycle and the electron transport chain. These reactions further break down the pyruvate and produce more ATP.At the end of the electron transport chain, oxygen accepts electrons and combines with hydrogen ions to form water.The energy released during these reactions is used to produce ATP, which is then used by cells to power various activities like muscle contractions, nerve impulses, and synthesis of molecules.

Answer 2
Final answer:

The human body acquires energy by metabolizing nutrients to form ATP, the energy currency of cells. This energy supports all bodily functions and activities. Excess energy is stored as fat, and the overall process is part of the body's metabolism.

Explanation:

Energy Conversion in the Human Body

The human body requires energy to perform various activities ranging from cellular processes to physical labor. Our bodies acquire energy by metabolizing nutrients from food, primarily through a process known as cellular respiration. This process converts the chemical energy present in food into adenosine triphosphate (ATP), which cells utilize to perform functions such as muscle contraction, molecule synthesis, and cellular transport. When we are at rest, the body consumes energy to maintain basic physiological functions like breathing and circulating blood, while during physical activities, much more energy is required to perform useful work.

The flow of energy through living systems, known as bioenergetics, dictates that the energy from food undergoes a conversion process. This includes the breakdown of complex carbohydrates into simple sugars and dietary amino acids into proteins, understanding that some chemical reactions within cells release energy (exergonic) and others require energy (endergonic). The aggregate of these reactions is referred to as metabolism. If we consume more energy than what's needed for daily activities and maintaining body temperature, the excess is stored as fat.

In summary, the conversion of chemical energy from food involves a series of metabolic processes that ultimately result in the generation of ATP, which powers various cellular and bodily functions. It is critical for the maintenance of life and allows humans to perform all manners of work, from the most mundane to the most strenuous of tasks.

A neutral atom of beryllium (Be) has an average mass of 9 amu and 4 electrons. How many neutrons does it have?

13
9
5
4

Answers

To find the number of electrons, just subtract the amu and the atomic number (aka number of protons or electrons)...

so it is...

9-4=5 neutrons

Brainliest plz! :)

The number of neutrons in a neutral atom of beryllium is equal to 5. Therefore, option (B) is correct.

What is a neutral atom?

A neutral atom can be defined as an atom in which the number of the negative charge is equal to the number of the positive charge. Therefore, the overall electric charge on the neutral atom is zero.

We can say that for a neutral atom, the number of protons in an atom is equal to the number of electrons in that atom. All elements arranged in the modern periodic table are in a neutral state.

The atomic mass or average mass of the atom is the sum of the number of protons and neutrons in the nucleus of that atom.

Given, the average mass of  beryllium (Be) atom = 9 amu

Therefore, protons + neutrons = 9 in the one Be atom

The number of electrons in Be atom = 4

The number of neutrons in netural beryllium atom = 9 - 4 = 5

Which one is a true statement about endothermic reactions?

A) The reaction container always feels hot.

B) More heat is given off than is put into the reaction.

C) The reactant have less heat energy than the products.

D) Energy is absorbed making it feel colder.

Answers

Answer;

D) Energy is absorbed making it feel colder.

Explanation;

An endothermic reaction is a reaction in which heat energy is absorbed from the surroundings. In such a reaction the energy of the reactants is less than the energy of the products and therefore the enthalpy change is positive, greater than zero.

An endothermic reaction occurs when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products. This means that overall the reaction takes in energy, therefore there is a temperature decrease in the surroundings.

Answer:

I completely agree that it is D) Energy is absorbed making it feel colder!

The alkali earth metals have five valence electrons.
Select the rewording of the statement that is true.
The alkali earth metals have one valence electron.
The alkali earth metals have two valence electrons.
The halogens have five valence electrons.
The alkali metals have five valence electrons.

Answers

Answer:

The alkali earth metals have one valence electron.

Explanation:

Alkali earth metals are elements that constitute Group I in the periodic table. These include: lithium (Li),  sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr).

The alkali earth  metals are characterised by a outer or valence electron configuration of ns¹.

Li = 2s¹, Na = 3s¹, K = 4s¹, Rb = 5s¹, Cs = 6s¹

Therefore, in their outermost or valence shell these elements have only one  electron.

Hence the given statement: that the alkali earth metals have 5 valence electrons is false. Instead it should be reworded as:

The alkali earth metals have one valence electron.

Final answer:

The alkali earth metals, located in the second group of the periodic table, have two valence electrons, not five. So, the true rewording of the given statement should be 'The alkali earth metals have two valence electrons'.

Explanation:

The statement that 'The alkali earth metals have five valence electrons' is incorrect. The alkali earth metals, which occupy the second group of the periodic table, actually have two valence electrons. Therefore, the correct rewording of the statement would be 'The alkali earth metals have two valence electrons'.

After a hormone enters the bloodstream, it is transported throughout the body, but the hormone only affects certain cells. The reason only certain cells are affected is that the membranes of these cells have specific

Answers

The membranes have specific receptors, you're welcome :).

Final answer:

Only certain cells are affected by hormones because these cells have specific receptor proteins that allow the hormone to bind and initiate a response. These receptors determine the cell's sensitivity to the hormone and can vary through up-regulation or down-regulation, adapting to hormone levels.

Explanation:

The reason only certain cells are affected by hormones is because only some cells have receptor proteins that can bind to a given hormone. These receptors are specific to a particular hormone and allow it to have an effect when it binds to them.

The hormone will travel throughout the bloodstream until it finds a cell with the correct receptor and binds to it, which initiates various responses depending on the type of hormone, such as a steroid hormone or a non-steroid hormone.

Hormones, acting as messengers, are crucial in regulating physiological processes. They play a significant role in human reproduction, development, metabolism, and maintaining homeostasis, among other functions.

The presence and quantity of hormone receptors determine which cells will respond to a given hormone, thus determining the sensitivity of the cell to the hormone. Cell sensitivity to hormones can change through processes like up-regulation and down-regulation, which adapt the number of receptors available in response to hormonal levels.

Hydrogen peroxide is sold as a 3.0% (by mass) solution. The rest of the solution is water . How many grams of hydrogen peroxide are in 250 grams of this solution?

Answers

Final answer:

The question deals with percent by mass calculations. For a 3.0% by mass solution of hydrogen peroxide, there are 3 grams of hydrogen peroxide in every 100 grams of the solution. Therefore, a 250-gram solution would contain 7.5 grams of hydrogen peroxide.

Explanation:

The solution of hydrogen peroxide is 3.0% by mass. This means that there are 3 grams of hydrogen peroxide in every 100 grams of solution. Therefore, in 250 grams of solution, the amount of hydrogen peroxide can be calculated by setting up a proportional equation:

(3 grams H2O2 / 100 grams solution) = X grams H2O2 / 250 grams solution

To solve for X, which represents the amount of hydrogen peroxide, cross multiply and divide:

(3 g H2O2 x 250 g solution) / 100 g solution = 7.5 g H2O2

So, there are 7.5 grams of hydrogen peroxide in a 250-gram solution.

Is nail polish a pure substance or a mixture?

Answers

Final answer:

Nail polish is a mixture made up of solvents, polymers, colorants, and additives. It can be physically separated into its different components.

Explanation:

Nail polish is a mixture, not a pure substance. It is made up of different components, such as solvents, polymers, colorants, and additives. These components are not chemically bonded together and can be separated from each other.

For example, if you leave a bottle of nail polish open, the solvents will evaporate, leaving behind a dried-up mixture. Additionally, if you mix two different colors of nail polish together, you will create a new mixture with a blend of the two colors. Therefore, nail polish is considered a mixture because it contains multiple substances that can be physically separated.

Nail polish is not a pure substance, but rather a mixture of several substances. A pure substance has a constant composition with fixed ratios of elements, but nail polish consists of a blend of different chemicals including solvents, film formers, resins, and plasticizers. Each of these components contributes to the characteristics of the final product, such as its ability to adhere to the nail, its durability, and its shine.

For instance, the film formers and resins create the hard coating on your nails that lasts for days, while the plasticizers provide flexibility so the polish doesn't chip or crack. Solvents are used to keep the other components in a liquid state so they can be easily applied to the nails. Once the polish is applied, the solvents evaporate, leaving behind the hard, colored film on the nail. This makes nail polish a mixture and not a pure substance.

CO2 is carbon dioxide which is most famous for being in gas form so i would figure if it was exposed to freezing temperatures it would turn into a liquid then maybe a solid

The options in the question are as follows

a. The motion of particles becomes random.

b. The motion of the particles is unchanged.

c. The particles move with more force.

d. The particles decrease in speed.

Answer:

The particles decrease in speed.

Explanation:

In a gas at room temperature, the particles of the gas move at a very high speed and in a random manner. A gas has no definite volume and it is also assumed that there is minimal interaction between gas particles. Recall that temperature is a measure of the average kinetic energy of the particles of a system. As the temperature is decreased and heat is withdrawn as the CO2 approaches freezing temperature, the speed and kinetic energy of the particles decreases and significant interaction between particles is observed. Hence the CO2 particles slow down.

a student determined in the laboratory that the percent by mass of water in cus04 5h20 is 38.0% if the accepted value is 40% what is the percent of error

Answers

Final answer:

The percent of error is calculated using the formula: Percent error = (Experimental Value - Accepted Value) / Accepted Value * 100%. In this case, the percent of error is -5%.

Explanation:

The percent of error can be calculated using the formula:

Percent error = (Experimental Value - Accepted Value) / Accepted Value * 100%

Given that the experimental value for the percent by mass of water in CuSO4 • 5H2O is 38.0% and the accepted value is 40%, the percent of error can be calculated as:

((38.0 - 40) / 40) * 100% = -5%

Therefore, the percent of error is -5%.

Final answer:

The percent error in the student's measurement of the percent by mass of water in CuSO4·5H2O is  5.0%. This is calculated by using the formula for percent error, which yields a percent error of 5.0%.

Explanation:

The student determined that the percent by mass of water in CuSO4·5H2O is 38.0%, but the accepted value is 40%.

To calculate the percent error, we use the formula:

Percent Error = (|experimental value - accepted value| / accepted value) × 100%

Substituting the given values:

Percent Error = (|38.0% - 40.0%| / 40.0%) × 100%

Percent Error = (2.0% / 40.0%) × 100% = 5.0%

Thus, the percent error in the student's measurement is 5.0%.
