how does the energy of the reactants and products differ between an energy absorbing reaction and an energy releasing reaction
Answers
The mass of the products is larger than the concentration of the reactants in an energy absorption process.
The power of the reaction mixture is larger than the radiation of the outputs in an energy-releasing process.
As substances disrupt bonds, energy released, and then when outputs make new bonds, release energy.
Exothermic processes release energy, whereas endothermic reactions consume it. There is no general change in the quantity of energy throughout a chemical process, whether it collects or releases it.

Podríamos decir que un ecosistema es un “Lugar”? Justifica tu respuesta.
Answers
Hello
first of all we know that an ecosystem is a biological system made up of a community of living organisms (biocenosis) and the physical environment where they are related (biotope). It is a unit composed of interdependent organisms that share the same habitat. Ecosystems often form a series of chains that show the interdependence of organisms within the system. It can also be defined as follows: "An ecosystem consists of the biological community of a place and the physical and chemical factors that constitute the abiotic environment." Abiotic and biotic factors are considered to be linked by trophic chains, that is, the flow of energy and nutrients in ecosystems.
This concept, which was introduced in 1935 by the English ecologist AG Tansley, takes into account the complex interactions between organisms (e.g. plants, animals, bacteria, protists and fungi) that form the community (biocenosis) and the energy flows and materials that pass through.
In more understandable terms, the ecosystem is not a place as such.

Briefly describe about the formation and management of HCL through the respiratory and renal systems in digestive system.
Answers
Answer:
Explanation:
HCl is produced by the parietal cells of the stomach. To begin with, water (H2O) and carbon dioxide (CO2) combine within the parietal cell cytoplasm to produce carbonic acid (H2CO3), which is catalysed by carbonic anhydrase. Carbonic acid then spontaneously dissociates into a hydrogen ion (H+) and a bicarbonate ion (HCO3–).
The hydrogen ion that is formed is transported into the stomach lumen via the H+– K+ ATPase ion pump. This pump uses ATP as an energy source to exchange potassium ions into the parietal cells of the stomach with H+ ions.
The bicarbonate-carbonic acid buffer works in a fashion similar to phosphate buffers. The bicarbonate is regulated in the blood by sodium, as are the phosphate ions. When sodium bicarbonate (NaHCO3), comes into contact with a strong acid, such as HCl, carbonic acid (H2CO3), which is a weak acid, and NaCl are formed. When carbonic acid comes into contact with a strong base, such as NaOH, bicarbonate and water are formed.
The bicarbonate ion is transported out of the cell into the blood via a transporter protein called anion exchanger which transports the bicarbonate ion out the cell in exchange for a chloride ion (Cl–). This chloride ion is then transported into the stomach lumen via a chloride channel.The respiratory system contributes to the balance of acids and bases in the body by regulating the blood levels of carbonic acid
Chloride ions are important in neutralizing positive ion charges in the body. If chloride is lost, the body uses bicarbonate ions in place of the lost chloride ions. Thus, lost chloride results in an increased reabsorption of bicarbonate by the renal system.

O A. When there are limited resources
O B. When the death rate is high
Han
O C. When carrying capacity is reached
O D. When there is no competition
Answers
Answer:
D. When there is no competition
Explanation:
If there is no competition in a population, exponential growth can occur.
Without competition, resources are not limited and a population can grow rapidly.
With limited resources, a high death rate, and a reached carrying capacity, population growth is strongly limited and cannot grow at an exponential rate.
So, answer choices A, B, and C are all incorrect.
The correct answer is D. When there is no competition

Iron-55 has a half-life of 3 years. How much of a 40 gram sample will remain after 12 years? A. 0 grams B. 4 grams C. 2.5 grams D. 20 grams
Answers
Answer:
[tex]\boxed {\boxed {\sf C. \ 2.5 \ grams }}[/tex]
Explanation:
We are asked to find how much of a 40 gram sample remains after 12 years.
Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed.
12 years/3 years = 4 half-livesEvery time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample.
1 half- life: 40 g / 2 = 20 g 2 half-lives: 20 g / 2= 10 g 3 half-lives: 10 g / 2 = 5 g4 half-lives: 5 g / 2 = 2.5 gThere is also a formula that can be used to solve this problem.
[tex]A= A_o(\frac {1}{2})^{\frac{t}{hl}[/tex]
Where A₀ is the initial amount, t is the time, and hl is the half-life.
We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife.
A₀= 40 g t= 12 hl= 3[tex]A= 40 \ g (\frac{1}{2})^\frac{12}{3}[/tex]
[tex]A= 40 \ g (\frac{1}{2})^4[/tex]
[tex]A= 40 \ g * 0.0625[/tex]
[tex]\bold {A= 2.5 \ g}[/tex]
After 12 years, 2.5 grams of Iron-55 will remain.

ANSWER:-AMOUNT OF SUNLIGHT ABSORBED.
Number of gene for color of the skin is same in all the human beings and also it's a genetic factors is there will be any absence of gene due to its deletion AMOUNT OF SUNLIGHT it is variable in variable reasons which is a imp factor for the color in variation in earth. In regions near to the equator have high amount of the light so they have darker skin color then the people near the poles as there is less amount of light .Number of gene inherited is also same for each and every individual for single species for human which is 378 gene loci and if there is any variation in number due to any genetics disorder it would be a genetic factor again.amount of food consumed is different for different people with same color in same region as it only depends on the work which is done by the individual in the society for its existence. though it is a environmental factor bit it didn't effect color of the species.SO ACCORDING TO ABOVE DETAILS WE CAN CONCLUDE (2) AMOUNT OF THE SUNLIGHT IS THE ENVIRONMENTAL FACTOR WHICH IS RESPONSIBLE FOR THE COLOR OF THE SKIN IN HUMANS

Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.
During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells
