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.

Which of the following is a normal process of photosynthesis that could not occur if all reaction centers were inactivated by a toxin?
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
B. absorption of photons by chlorophyll b
C. absorption of photons by carotenoids
D. donation of excited electrons by chlorophyll b to a primary electron acceptor

Answers

Answer:

A. donation of excited electrons by chlorophyll a to a primary electron acceptor

Explanation:

Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.

Why does climate change affect so many things?

Answers

Answer:

These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.

Explanation:

According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.

In the process of photosynthesis, _______ in autotrophs convert solar energy into chemical energy and store this 'food' for later use. The reaction for photosynthesis is: 6CO2(g) + 6H2O(l) + energy --> C6H12O6(s) + O2(g). In the process of ________, mitochondria in the cells of plants, animals and other multicellular organisms break down 'food' molecules to generate molecules of _______ . This is the source of energy for all cellular functions. The reaction for cellular respiration is: ________


ATP
chemosynthesis
chloroplasts
cellular respiration
NADPH and FADH2
C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy

Answers

Answer:

1. Chloroplast

2. cellular respiration

3. ATP

4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy

Explanation:

This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:

6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)

Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:

C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy

During a recent hurricane, 25 individuals of the same butterfly species were blown onto a barrier island in southern Florida. Prior to this event, this species did not inhabit the island, but with the ample vegetation on the island and a lack of predators, the displaced individuals were able to survive and reproduce. When the butterflies initially arrived on the island, they did not have to compete for food or space. What type of population growth did they likely exhibit

Answers

Answer: Exponential

Explanation:

The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.

This is what happened with humans during the Neolithic Revolution when we began farming.

The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.

Answer:

Exponential growth

Explanation:

Without any competition for food or space, the butterfly species likely experienced exponential growth.

The lack of competition would have allowed the population to flourish, as they would have excess amounts of resources, food, space, and other limiting factors.

So, they most likely exhibited exponential growth.

1 Reproduction is an important characteristic of living organisms.Explain

Answers

Answer:

Reproduction is one of the most important characteristics of living beings, because -

- The existence of any species is dependent on the reproduction because no living being is immortal.

After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.

And,the birth of newborns of next generation is only possible by the reproduction.

- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.

- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.

And as mentioned before,these newborns are only possible due to reproduction.

When can exponential growth happen?

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
